China Post Tracking

Track a China Post shipment on this page

Enter the identifier exactly as shown in:

• the sender’s shipment notice;
• the merchant or marketplace order record;
• a China Post or EMS receipt;
• the printed label;
• an official carrier or destination-post record.

Preserve:

• every letter and digit;
• leading zeros;
• the original sequence;
• the original identifier even if a second local number appears later.

The public promise on this page is:

Enter one supported China Post-associated tracking identifier.

Do not substitute:

• a merchant order number unless it is explicitly identified as the carrier’s tracking number;
• a marketplace account number;
• a customs payment reference;
• a complaint or inquiry case number;
• a local delivery release code;
• a recipient name, phone number, email address, or street address.

Why does the wording say “China Post-associated”?

The route can involve more than one entity.

The identifier can belong to:

• China Post international letter post;
• China Post international parcel post;
• China Postal EMS;
• ePacket;
• a registered, tracked, or ordinary small-packet product;
• a China Postal EMS commercial channel;
• a commercial carrier that receives the shipment later;
• a destination-country postal operator;
• a marketplace or consolidator record that is not itself proof of China Post possession.

The active provider and event source must be verified before the page describes a specific carrier as responsible.

China Post, EMS, ePacket, Cainiao, and commercial partners are different

Keep these distinctions visible:

China Post ≠ every EMS product

ePacket = China postal/EMS product ≠ separate universal carrier

Cainiao tracking record ≠ one physical carrier throughout the route

seller says shipped ≠ China Post accepted the item

same corporate postal ecosystem ≠ identical provider, tracking depth, proof, or claim terms

What is ePacket?

ePacket, also written e邮宝, is a China postal/EMS cross-border ecommerce product for lightweight goods.

Current official product material describes major tracking nodes and delivery information.

Use:

ePacket → identified postal ecommerce product ≠ separate universal carrier ≠ continuous live tracking ≠ identical destination coverage ≠ guaranteed delivery time

The destination postal operator or partner can control the later record.

China Post product and tracking-coverage classifier

“Full tracking” is still event-based

A product described as fully tracked can publish more milestones, but this does not mean:

• continuous GPS;
• every physical movement;
• every airport transfer;
• guaranteed scan timing;
• every customs action;
• every destination attempt;
• public proof for every delivery.

Product recognition does not prove event coverage

A number can be recognised while:

• only origin events are available;
• the destination operator has not published events;
• the product is unregistered;
• a commercial partner uses another number;
• customs interrupts the sequence;
• the active provider omits events.

S10 identifiers and other China Post tracking numbers

What is an S10 identifier?

The Universal Postal Union’s S10 standard defines a 13-character postal identifier:

• two letters for the service indicator;
• eight serial digits;
• one check digit;
• two letters for the country-code suffix.

Many international China Post, EMS, registered, and parcel products use this architecture.

What does the CN suffix mean?

The suffix indicates the authority under which the identifier was issued.

Use:

S10 suffix CN → identifier issued under China’s assigned postal authority ≠ parcel currently in China ≠ China Post currently controls the item ≠ parcel was manufactured or purchased in China

The same identifier can continue after a destination postal operator receives the item.

The first two letters do not prove the complete product

The service-indicator letters can provide structural information, but the prefix alone does not safely prove:

• EMS;
• ePacket;
• registered mail;
• parcel post;
• compensation;
• destination tracking;
• delivery speed;
• current operator.

Do not assume that every identifier beginning with E is automatically the same EMS service.

No universal China Post identifier length is confirmed

S10 identifiers use 13 characters, but not every:

• domestic China Post code;
• commercial-channel code;
• marketplace logistics number;
• partner-carrier number;
• destination local number

uses S10.

The public page must not reject an identifier solely because it does not match a popular S10 pattern.

Original tracking number and destination local number

A destination operator or commercial partner can:

• continue using the original S10 identifier;
• create an internal mapping;
• publish a second local number;
• expose the local number only in its own system;
• use no public second number.

Use:

second local number appears → later operator or mapping may exist ≠ original number is fake ≠ original history should be discarded

Preserve:

• the original identifier;
• the local identifier;
• the handoff event;
• the name of the current operator.

Do not promise that USPS, Royal Mail, or any other national post always handles every China Post shipment. Commercial channels and partner carriers can use different last-mile operators.

Use Find the Last-Mile Carrier for the wider operator-discovery process.

A recognised number does not prove China Post possession

Read the evidence in stages.

Use What Does “Label Created” Mean? and Carrier Received Package for the broader cross-carrier evidence model.

Seller “shipped” and China Post acceptance are different

A seller or marketplace can mark an order as shipped after:

• creating a label;
• assigning a logistics number;
• transferring the parcel to a warehouse;
• giving it to a consolidator;
• scheduling a pickup.

This does not prove that China Post or EMS physically accepted it.

Stronger evidence includes:

• a post-office receipt;
• Posting;
• Collection;
• Acceptance;
• another clearly attributed origin-post scan.

Use:

seller says shipped → commercial order workflow advanced ≠ postal possession

Posting, collection, and acceptance

Posting or collection

A posting or collection event can indicate that the item entered the origin postal process.

Use:

posting or collection → stronger physical handover evidence ≠ international dispatch completed

It does not prove:

• the contents were verified;
• the declared value is correct;
• export customs cleared;
• the item left China;
• the delivery date is guaranteed.

Acceptance

An acceptance event is a stronger possession boundary.

Use:

accepted by China Post or EMS → origin operator records physical intake ≠ item exported ≠ every later scan guaranteed

Early return or security event

An item can be returned or stopped because of:

• prohibited contents;
• incomplete data;
• packaging;
• security screening;
• customs;
• sender action;
• operational correction.

Do not assign a specific cause unless the exact event or official notice states it.

Offices of exchange and international postal dispatch

What is an office of exchange?

An office of exchange handles international postal mail exchanged between designated operators.

It can:

• receive items from the domestic network;
• prepare dispatch;
• group mail into receptacles or bags;
• exchange electronic messages;
• send mail toward another operator;
• receive inbound international mail.

Arrival at outward office of exchange

This means the item entered an export postal-processing stage.

Use:

arrival at outward office of exchange → export postal processing ≠ export dispatch ≠ aircraft departure ≠ destination customs

Departure from outward office of exchange

This indicates that a postal dispatch stage was recorded.

Use:

departure from outward office of exchange → mail moved out of the origin exchange-office stage ≠ parcel confirmed on a specific aircraft ≠ direct flight ≠ destination arrival

Dispatched from office of exchange

This is a postal-dispatch event.

It does not establish:

• the exact transport mode;
• continuous movement;
• flight number;
• destination receipt;
• customs release.

Item event and mailbag event can differ

International post can move in bags, receptacles, containers, or consolidated loads.

A public item record can be based on:

• an item scan;
• a receptacle dispatch;
• an electronic message;
• partner data;
• later event exchange.

The public wording does not always reveal the physical granularity.

“Handed over to airline” does not mean live flight tracking

Handed over to airline

Use:

handed over to airline → transport handoff or preparation stage recorded ≠ aircraft departed ≠ package is on a specific flight ≠ direct route ≠ destination country received the item

The parcel can still:

• wait for capacity;
• remain in a consolidated mail unit;
• move by road to another airport;
• be rebooked;
• transit another country.

Airline departure

Use:

airline departure → transport departure event was published ≠ continuous flight tracking ≠ nonstop movement ≠ customs release ≠ destination-post receipt

Airline reception

Translated wording such as airline reception can refer to acceptance by a transport actor or a normalized logistics code.

It does not mean recipient delivery.

Repeated airline events

Repeated or similar airline events can reflect:

• multiple transport legs;
• electronic-message updates;
• consolidation;
• transfer between facilities;
• rebooking;
• third-party normalization.

Do not infer loss or circular movement from repeated wording alone.

China Post shipments do not always travel by air

Current official product material supports:

• air;
• surface;
• combined air and surface;
• rail;
• road;
• commercial express networks.

The product and route control.

Safe China Post international event ladder

Not every tracker displays every stage, but this conceptual ladder is useful:

seller or merchant record → posting or acceptance → origin processing → outward office of exchange → origin dispatch → transport → destination office of exchange → import customs → destination-post processing → delivery office → attempt, pickup, or delivery

Events can be delayed or out of order

Possible reasons include:

• delayed electronic exchange;
• item-level scans arriving after receptacle data;
• provider normalization;
• destination operator publishing first;
• time-zone conversion;
• duplicate messages;
• later reconstruction.

Do not treat a displayed order as perfect proof of the physical sequence when timestamps or sources conflict.

No universal English event dictionary

Different providers can translate one underlying postal event differently.

Preserve:

• original event text where available;
• event source;
• operator;
• timestamp;
• location;
• normalized explanation.

Do not map every phrase to one UPU code unless the active provider exposes and verifies the code.

Destination-country arrival, customs, and postal receipt are different

Use this state model:

arrival in destination country or region → destination-side transport or exchange process ≠ customs released ≠ destination post received item-level custody ≠ delivery started

A destination-arrival event can precede:

• mailbag opening;
• import presentation;
• customs assessment;
• destination-post item scan;
• local-number mapping;
• domestic sorting.

Destination postal operator controls the last mile

After handoff, the destination postal operator or carrier can control:

• domestic sorting;
• attempts;
• neighbor or safe-place delivery;
• pickup;
• holding period;
• signature;
• proof;
• return;
• local support.

China Post origin rules do not create one universal destination workflow.

Use:

destination-post event → local operator controls that stage ≠ China Post still controls the physical last mile

Use Handed to Local Carrier and How International Package Tracking Works for the broader handoff model.

Why China Post tracking can stop updating

Gap after seller record

Possible reasons include:

• label created but no handover;
• consolidator holding the parcel;
• wrong identifier;
• first postal scan delayed;
• unregistered or limited product;
• provider mapping problem.

Evidence that changes the conclusion:

• posting receipt;
• acceptance scan;
• origin postal event.

Gap after acceptance

Possible reasons include:

• domestic transport;
• exchange-office queue;
• security screening;
• export customs;
• seasonal congestion;
• missed scan.

Evidence that changes the conclusion:

• outward-office processing;
• dispatch;
• transport event;
• return event;
• formal sender inquiry.

Gap after outward dispatch or airline event

Possible reasons include:

• transport capacity;
• consolidated mail;
• transit country;
• delayed electronic exchange;
• destination customs;
• destination operator not publishing item-level events;
• limited product tracking.

Evidence that changes the conclusion:

• destination arrival;
• customs notice;
• destination-post event;
• local tracking number.

Gap after destination arrival

Possible reasons include:

• import customs;
• mailbag or receptacle opening;
• item-level sorting;
• local mapping;
• delayed data exchange;
• commercial handoff.

Limited visibility can be normal

For ordinary or unregistered small packets, origin-only or sparse tracking can be consistent with the product.

Use:

limited or unregistered product → destination scans may be absent ≠ item automatically lost

The absence of public events does not prove successful delivery either.

When escalation becomes stronger

Escalation is more justified when:

• the merchant’s promised delivery window has passed;
• the destination operator reports no receipt after a route-specific period;
• customs requests action;
• the item is marked returned;
• the sender has proof of posting and the formal inquiry window is open;
• a tracked or high-value product has an unexplained long gap;
• a product-specific deadline is approaching.

Use Tracking Not Updating for the complete cross-carrier decision model.

Customs and postal handling are separate

Actor model

Customs state model

electronic advance data → export acceptance or security → international dispatch → destination arrival → import presentation → document or payment request → assessment → payment → customs release → destination-post processing → delivery

Keep these boundaries:

customs event ≠ delivery-ready

documents submitted ≠ accepted

payment requested ≠ paid

paid ≠ customs released

customs released ≠ destination post sorted the item

destination sorting ≠ delivered

China’s postal customs platform

China Customs and China Post have published an official one-stop platform for inbound and outbound postal items.

It can support official customs-status and action workflows.

11Tracking cannot access that private customs process or submit documents on the user’s behalf.

United States low-value import rules reviewed in July 2026

Duty-free de minimis treatment remains suspended in the current rule

Current U.S. official material reviewed on July 25, 2026 states that duty-free de minimis treatment remains suspended for covered low-value shipments.

Do not rely on older generic advice that every parcel under USD 800 enters the United States duty free.

New postal informal-entry process

U.S. Customs and Border Protection states that a new mail informal-entry process takes effect on July 24, 2026.

This is a high-volatility rule and should be verified against the shipment-specific U.S. customs or destination-post process.

No universal U.S. charge can be calculated from tracking alone

The amount and procedure can depend on:

• tariff classification;
• country of origin;
• declared value;
• product;
• applicable trade measures;
• entry method;
• postal or commercial route;
• exemptions;
• current legal authority;
• handling charges.

11Tracking cannot calculate or pay a shipment-specific duty.

Postal and commercial routes can differ

A China Post-branded seller record does not prove that the U.S. entry remains a postal-mail entry.

Commercial-channel products can use:

• commercial customs;
• express partners;
• another last-mile carrier;
• a separate local tracking number.

European Union low-value import rules reviewed in July 2026

Temporary EUR 3 duty

From July 1, 2026, the European Union applies a temporary EUR 3 customs duty in the scoped low-value distance-sale flow for consignments up to EUR 150.

The measure is scheduled through July 1, 2028.

The duty is not simply once per parcel

Current European Commission guidance describes the duty by qualifying item or tariff classification under the declaration.

Illustrative logic in the official guidance includes:

several identical products in one classification → one EUR 3 classification line in the example

products in two classifications → EUR 6 in the example

Use this safe formulation:

The temporary duty is calculated by qualifying item or tariff classification under the customs declaration, not simply once per parcel and not necessarily once per physical unit.

The actual customs declaration and destination invoice control.

IOSS does not automatically remove the duty

VAT paid through IOSS does not automatically eliminate the temporary customs duty in the main scoped flow.

Keep separate:

• VAT;
• customs duty;
• excise or other taxes;
• destination-post or carrier handling fees;
• marketplace-collected charges.

Product Identifier timeline

The European Commission says Product Identifiers can be declared voluntarily from July 1, 2026 and become mandatory from November 1, 2026 in the scoped system.

This can affect customs data quality and processing but does not by itself prove customs release.

Customs payment does not prove release

Use:

customs payment requested ≠ payment completed

payment completed ≠ customs released

customs released ≠ destination-post processing completed

destination-post processing ≠ delivery started

Verify payment through an independently opened official customs, destination-post, or carrier workflow.

Use Customs Processing, Package Stuck in Customs, and Customs Cleared but No Update for the wider action model.

Delivery attempts, pickup, and holding periods vary by destination

Once the destination operator receives the item, its rules control.

Do not publish one universal China Post rule for:

• number of delivery attempts;
• neighbor delivery;
• safe place;
• pickup point;
• locker;
• holding period;
• identity requirement;
• signature;
• proof;
• return.

A generic Available for pickup event does not establish:

• exact location;
• deadline;
• required ID;
• authorization rules;
• customs payment;
• successful collection.

Use the destination operator’s notice and official tracking.

Delivered does not always prove named-recipient receipt

The destination operator can record delivery to:

• the named recipient;
• a household member;
• a neighbor;
• reception;
• a safe place;
• a pickup point;
• a locker;
• another product-specific location.

Use:

Delivered → publishing operator records completion ≠ named addressee personally received in every product ≠ contents or condition proved ≠ merchant refund automatically resolved

The strongest local proof may exist only in the destination operator’s system.

Use Delivered but Not Received and Proof of Delivery, Photo, and Signature for the broader procedure.

Signature and proof are product-specific

Possible evidence includes:

• delivery status;
• signature;
• collector or addressee name;
• delivery location;
• pickup record;
• local carrier proof;
• EMS proof;
• destination-post record.

Do not promise that every China Post or ePacket shipment includes:

• signature;
• named-recipient identity;
• downloadable proof;
• complete destination history;
• compensation.

A signature does not automatically prove:

• package contents;
• package condition;
• correct item;
• later possession;
• absence of delivery error.

Who should investigate a missing China Post international item?

China Post’s official English contact guidance says the sender should go to the local posting office to complete the formal inquiry procedure for an international item.

Use:

recipient sees a problem → recipient contacts seller or sender → sender uses posting receipt and origin-post inquiry

recipient concern ≠ recipient automatically controls China Post formal inquiry

Current inquiry window in the scoped universal-service standard

China’s universal postal-service standard says an international registered item can be queried within 180 days from posting using the receipt.

This is a scoped postal rule.

Do not generalize it to:

• every EMS commercial product;
• every unregistered packet;
• every destination-country claim;
• every marketplace refund deadline;
• every partner-carrier shipment.

Current inquiry-response framework

The same standard describes international and remote-area inquiry responses within 30 days where possible and no later than 60 days in the stated framework.

This is not:

• a guaranteed delivery time;
• proof of loss;
• a compensation deadline;
• a merchant refund deadline.

Complaint and formal inquiry are different

• Complaint: reports dissatisfaction with service.
• Formal inquiry: traces a postal item using the sender’s posting evidence.
• Postal compensation: product- and liability-specific outcome.
• Merchant remedy: refund or replacement under the purchase relationship.

An inquiry case does not prove:

• loss;
• liability;
• compensation;
• refund;
• replacement.

Postal compensation and merchant refund are separate

Under the international postal framework, inquiry and indemnity rights generally begin with the sender, with product- and national-rule exceptions or transfer mechanisms.

For a retail purchase, the merchant controls:

• order contents;
• value;
• seller records;
• carrier contract;
• refund;
• replacement;
• marketplace dispute.

Use:

postal compensation ≠ merchant refund

sender inquiry ≠ refund approved

carrier liability decision ≠ marketplace dispute outcome

Do not publish one universal China Post compensation amount.

Evidence to preserve for a China Post problem

Keep private copies of:

• merchant order;
• original tracking identifier;
• local tracking identifier;
• posting receipt;
• product name;
• declared value;
• customs declaration;
• tracking timeline;
• destination-post record;
• proof or signature;
• packaging;
• damage photos;
• merchant messages;
• inquiry case.

Do not publish unredacted identifiers, addresses, customs documents, signatures, or identity data.

Use Who to Contact About a Package and Package Claim Guide for the broader actor and claim model.

Returns and return-to-sender tracking

Return state model

delivery fails, recipient refuses, or customs blocks the item → destination operator records return branch → destination export or customs handling → international return dispatch → China Post or partner receives the return → sender or merchant receives the item → inspection → refund or replacement decision

Keep these boundaries:

return initiated ≠ returned to China

returned to origin country ≠ sender received

sender received ≠ refund approved

refund approved ≠ refund paid

A return can use a new number

The destination operator or commercial partner can create another reference.

Preserve both identifiers and the mapping.

Undeliverable items do not have one universal outcome

Destination-country law, customs rules, UPU terms, product conditions, and sender instructions can affect:

• return;
• storage;
• abandonment;
• customs disposal;
• destruction;
• recovery charges.

Do not infer the final outcome from one generic exception.

Use Return to Sender for the wider evidence model.

Who should act on a China Post tracking problem?

11Tracking cannot contact China Post, EMS, Cainiao, an airline, customs authority, destination post, commercial partner, sender, or merchant on your behalf.

Verify China Post, customs, and delivery messages safely

A fraudulent message can contain:

• a real tracking identifier;
• a correct destination city;
• a current customs phrase;
• a real delivery event;
• China Post, EMS, or destination-post branding;
• a plausible amount;
• a genuine local number.

Therefore:

real tracking number ≠ authentic message

correct event ≠ official payment link

carrier logo ≠ official website

Use this procedure:

1. Open the official China Post, EMS, destination-post, or customs site independently.
2. Enter only the identifier required by that official system.
3. Identify the current operator.
4. Verify any local number through the named operator.
5. Use the official shipment-specific customs or payment flow.
6. Contact the seller for retail disputes.
7. Never publish the full customs notice, proof document, identity document, signature, or payment data.

Use Fake Delivery Message for the complete scam procedure.

Protect China Post tracking, customs, and proof data

Treat the following as sensitive:

• original tracking identifier;
• destination local number;
• merchant order number;
• sender and recipient names;
• full address;
• phone and email;
• customs reference;
• customs declaration;
• commercial invoice;
• identity document;
• payment data;
• signature;
• proof document;
• complaint or inquiry case;
• marketplace account;
• local release code.

Do not place those details into:

• a public forum;
• an unredacted screenshot;
• a public URL;
• metadata;
• JSON-LD examples;
• analytics;
• an unverified support form;
• a public AI prompt.

A public tracking explanation does not require a full address, identity document, customs invoice, payment card, signature, or marketplace login.

Frequently asked questions

How do I track a China Post package?

Enter one supported China Post-associated tracking identifier in the form on this page. Preserve every letter, digit, and leading zero.

Does a recognised number prove China Post has the parcel?

No. A seller, marketplace, warehouse, or consolidator can create a record before postal acceptance.

What proves China Post accepted the item?

A posting receipt, collection event, acceptance event, or another clearly attributed origin-post scan is stronger evidence than label creation.

Is every China Post tracking number 13 characters?

No. UPU S10 identifiers have 13 characters, but domestic, commercial, partner, marketplace, and local numbers can differ.

What does the CN suffix mean?

It indicates the postal authority under which an S10 identifier was issued. It does not prove current location.

Does CN mean the parcel is still in China?

No. The same S10 identifier can continue after the item reaches the destination country.

Is every identifier beginning with E an EMS shipment?

No. The prefix alone does not safely prove the exact product or provider.

Is China Post the same as China EMS?

No. They are related within China’s postal system, but EMS has a separate product and tracking environment.

Is ePacket a carrier?

No. ePacket is a China postal or EMS ecommerce product that uses destination partners.

Is Cainiao the same as China Post?

No. Cainiao is a logistics platform and network that can display events from several actors.

Can I use my marketplace order number?

Only when the marketplace explicitly identifies it as the carrier’s tracking number. An order number is normally a purchase reference.

What is an S10 identifier?

It is a 13-character international postal identifier defined by the Universal Postal Union.

Can a China Post parcel receive a second tracking number?

Yes. A destination operator or commercial partner can create or expose a local number.

Does a second number mean the original number is fake?

No. Preserve both numbers and verify the mapping with the current operator.

Does every S10 identifier work on the destination post’s website?

No. Product, data exchange, and destination-operator support vary.

What is an ordinary China Post small packet?

It is an economy letter-post product that can have limited or origin-only visibility.

Can an ordinary packet be delivered without destination scans?

Yes. Limited visibility can be consistent with the product, but the lack of scans does not prove delivery.

Does seller status “shipped” mean China Post accepted the parcel?

No. The seller can mark it shipped after creating a label or transferring it to a warehouse or consolidator.

What does Posting or Collection mean?

It is stronger origin-post handover evidence. It does not prove export or destination arrival.

What does Acceptance mean?

The origin operator records physical intake into its process. It does not prove export.

What is an outward office of exchange?

It is an international postal facility that prepares or processes mail exchanged with another postal operator.

Does departure from the outward office mean the plane left?

No. It records postal dispatch from the exchange-office stage, not a confirmed aircraft departure.

What does Handed over to airline mean?

A transport handoff or preparation stage was recorded. It does not prove the item is on a specific flight.

What does Airline departure mean?

A transport departure event was published. It is not continuous flight tracking and does not prove destination arrival.

What does Airline reception mean?

It is usually a translated transport-acceptance event. It does not mean the recipient received the package.

Can a China Post parcel travel through another country?

Yes. Consolidation, transit, gateways, road transfer, rail, and mixed transport can create intermediary-country events.

Why are airline events repeated?

Multiple legs, rebooking, consolidation, data exchange, or provider normalization can produce repeated wording.

Does every China Post parcel travel by air?

No. Products can use air, surface, rail, road, combined transport, or commercial express networks.

Does arrival at the destination country mean customs cleared?

No. Import presentation, assessment, payment, release, and destination-post receipt can follow.

Does customs processing prove the destination post has the parcel?

Not necessarily. Customs and the postal operator are separate actors.

Does customs payment mean the parcel was released?

No. Payment, customs release, destination sorting, and delivery are separate stages.

Why did China Post tracking stop after leaving China?

The item can be in transport, transit, customs, destination processing, limited-tracking service, or delayed data exchange.

Why does the destination post show more events?

The destination operator controls the local stage and can publish domestic scans not visible through the origin tracker.

Who delivers China Post in my country?

The product and route control. It can be the national post or a commercial partner.

Does USPS always deliver China Post in the United States?

No. Postal and commercial-channel products can use different last-mile operators.

How do I find the last-mile carrier?

Look for the handoff event, destination operator name, and any verified local tracking number.

Why did the tracking number change?

A destination operator, gateway, or commercial partner can create a local reference.

Why do Cainiao and China Post show different events?

Cainiao can aggregate seller, warehouse, consolidator, postal, customs, and destination-carrier data.

Why are tracking events out of order?

Electronic messages, time zones, delayed scans, duplicate data, or provider normalization can affect display order.

How long should I wait after an airline or outward-office event?

No universal period is supported. Use the product, route, destination, merchant promise, and later operator evidence.

When should the sender open an inquiry?

When the tracked product has an unresolved route-specific delay and the formal inquiry window is open.

Can the recipient open the formal China Post inquiry?

China Post’s official English guidance directs the sender to the local posting office for the formal international inquiry.

How long is the China Post international inquiry window?

The reviewed universal-service standard gives 180 days from posting for the scoped registered international item.

Does the 180-day period apply to every EMS or commercial shipment?

No. It is a scoped postal standard, not a universal product rule.

How long can an international inquiry take?

The reviewed standard describes 30 days where possible and no later than 60 days in the stated framework.

Does opening an inquiry prove the parcel is lost?

No. It begins an investigation and does not establish liability or compensation.

Is postal compensation the same as a merchant refund?

No. Postal compensation belongs to the carrier relationship; refund or replacement belongs to the purchase relationship.

Does Delivered prove the named recipient received the parcel?

No. The destination operator can deliver to a household member, neighbor, reception, safe place, point, locker, or another allowed location.

Does every China Post shipment have a signature?

No. Signature and proof depend on the product and destination operator.

Can China Post provide the destination proof of delivery?

Sometimes the strongest proof exists only with the destination operator. Public availability varies.

How many delivery attempts does China Post make abroad?

No universal number exists. The destination operator and product control.

How long is a China Post parcel held for pickup abroad?

The destination operator’s notice and product control.

Does return to sender mean the parcel is already back in China?

No. Return initiation, international transport, origin-country arrival, sender receipt, and refund are separate stages.

Can a return use a new tracking number?

Yes. A destination operator or commercial partner can create another reference.

Does a return event mean my refund is complete?

No. Merchant receipt, inspection, approval, and payment come later.

What changed for U.S. low-value imports in 2026?

Current U.S. official material reviewed in July 2026 says duty-free de minimis treatment remains suspended for covered low-value shipments.

Is the old USD 800 de minimis rule still a safe assumption?

No. Do not rely on older generic advice that every parcel below USD 800 enters duty free.

What changed for U.S. postal imports on July 24, 2026?

CBP says a new mail informal-entry process takes effect on that date.

Can 11Tracking calculate U.S. customs duty?

No. Classification, origin, value, route, legal authority, and handling affect the result.

What changed in the European Union on July 1, 2026?

A temporary EUR 3 customs duty began in the scoped low-value distance-sale flow for consignments up to EUR 150.

Is the EUR 3 duty once per parcel?

No. Current EU guidance uses qualifying item or tariff classification under the declaration.

Does IOSS remove the temporary EU duty?

Not automatically. VAT and customs duty are separate.

Can the destination post charge a handling fee?

Yes. A carrier or post can charge handling separately from customs duty and VAT.

How do I verify a customs-payment message?

Open the official customs, destination-post, or carrier site independently and use the shipment-specific official workflow.

Can 11Tracking locate the flight carrying my package?

No. Airline-related tracking events are not live flight tracking.

Can 11Tracking contact China Post or EMS?

No. It cannot contact carriers, postal offices, airlines, customs, sellers, or destination operators.

Can 11Tracking open an international inquiry or claim?

No. Use the sender-led official inquiry and merchant-remedy routes.

Can 11Tracking pay customs or clear the parcel?

No. It cannot submit documents, accept payment, or obtain customs release.

Can 11Tracking retrieve a signature or proof of delivery?

No. Proof remains with the relevant official carrier or destination operator.

Keep China Post updates together in USTracking

After identifying the product, original number, latest event, current operator, local number, customs stage, and responsible actor, USTracking can help you:

• save a supported China Post-associated identifier;
• preserve the original identifier and a verified local number;
• organize public events in one timeline;
• monitor later public updates;
• compare China Post, EMS, customs, and destination-operator events when available;
• organize outbound, inbound, and return shipments;
• receive notifications.

USTracking cannot:

• track by name, phone, email, address, identity, or merchant order;
• unlock private marketplace or postal-account data;
• determine the exact China Post product from an unsupported prefix alone;
• identify a live flight;
• contact China Post, EMS, Cainiao, an airline, customs authority, destination post, commercial partner, sender, merchant, or delivery worker;
• create a formal inquiry, complaint, claim, compensation request, return, refund, or replacement;
• change delivery;
• retrieve a local release code;
• retrieve private signatures or proof;
• submit customs data;
• calculate or pay duties, VAT, or handling fees;
• clear customs;
• create, alter, or correct carrier scans;
• recover, accelerate, reroute, release, collect, or guarantee a shipment.

Use USTracking as a public-event monitoring and interpretation companion, not as a substitute for China Post, EMS, the destination operator, customs authority, seller, or merchant.

Scope and limitations

• This page explains China Post-associated identifiers, EMS, ePacket, product tracking depth, posting and acceptance, exchange offices, airline and transport wording, destination handoff, local tracking numbers, customs, delivery, proof, inquiries, claims, and returns. It does not diagnose an individual shipment.
• The public form is intended for one supported China Post-associated identifier. It does not automatically accept every order number, Cainiao number, customs reference, inquiry case, local release code, name, phone, email, or address.
• China Post, China Postal EMS, ePacket, Cainiao, marketplaces, commercial partners, airlines, customs, and destination operators are separate entities, products, or stages.
• ePacket is a product, not a separate universal carrier.
• A recognised identifier does not prove China Post physical possession.
• Seller or marketplace shipped status does not prove postal acceptance.
• UPU S10 identifiers use 13 characters, but not every China Post-associated number uses S10.
• The CN suffix identifies the issuing postal authority and does not prove current location or current operator.
• The first two letters do not safely prove the complete product, compensation, delivery speed, or destination tracking.
• No universal China Post identifier prefix, length, or regex was confirmed.
• A second destination local number can be legitimate and does not automatically invalidate the original identifier.
• Product recognition does not prove full event coverage.
• Ordinary or unregistered small packets can have limited or origin-only visibility.
• “Full tracking” remains scan-based and does not mean continuous GPS or every movement.
• Posting or acceptance is stronger possession evidence but does not prove export.
• An outward-office event records international postal processing and does not prove aircraft departure.
• Handed over to airline, Airline departure, and similar wording are transport-stage events, not live flight tracking.
• Repeated airline events do not identify one cause.
• China Post products can travel by air, surface, rail, road, mixed transport, or commercial express.
• Destination-country arrival does not prove customs release, destination-post receipt, or delivery start.
• Events can be delayed, duplicated, normalized, translated differently, or displayed out of order.
• The destination postal operator or commercial partner can control the later record.
• No universal USPS, Royal Mail, or other destination-carrier mapping was confirmed.
• No universal international delivery-attempt count, pickup period, neighbor rule, signature, or proof applies.
• A Delivered event records completion in the publishing operator’s system and does not universally prove named-recipient receipt, contents, or condition.
• Formal international inquiry is sender-led in the reviewed China Post guidance.
• The 180-day inquiry period and up-to-60-day response framework are scoped to the reviewed universal-service standard and do not apply to every commercial or unregistered product.
• Opening an inquiry does not prove loss, liability, compensation, refund, or replacement.
• Postal compensation and merchant refund are separate.
• A return event does not prove that the parcel is back in China, received by the sender, inspected, refunded, or paid.
• The U.S. low-value import guidance described here reflects official material reviewed July 25, 2026 and is highly volatile.
• Current U.S. official material says duty-free de minimis treatment remains suspended for covered low-value shipments.
• CBP says a new mail informal-entry process takes effect July 24, 2026.
• No shipment-specific U.S. duty can be calculated from tracking alone.
• The temporary European Union EUR 3 duty described here began July 1, 2026 and is scheduled through July 1, 2028 in the scoped flow.
• The EUR 3 duty is based on qualifying item or tariff classification under the customs declaration, not simply once per parcel.
• IOSS does not automatically remove the temporary customs duty.
• VAT, duty, excise, destination-post or carrier handling fees, and marketplace-collected charges are separate.
• Product Identifiers become mandatory from November 1, 2026 in the scoped EU system described by the current guidance.
• Customs assessment, document request, payment, release, destination-post processing, and delivery are separate stages.
• Legitimate customs charges can exist, but a real identifier or correct event does not authenticate a message or payment link.
• China Post products, routes, tracking depth, event wording, provider mappings, destination partners, customs laws, service alerts, inquiry rules, and proof availability are highly volatile.
• 11Tracking and USTracking are not China Post, EMS, Cainiao, an airline, customs authority, destination post, commercial partner, sender, merchant, or marketplace and cannot act on the physical shipment.
• Verify high-stakes customs, payment, delivery, proof, inquiry, claim, return, and compensation questions through the current official shipment-specific workflow before acting.
