About ZH

ZH(ZhongHang Logistics or 中航国际供应链) is the display name used here for Guangzhou Zhonghang International Supply Chain Co., Ltd., a Guangzhou-based cross-border logistics and supply-chain provider. ZH describes its role as arranging international express, dedicated cross-border lines, postal and SF small-packet services, air freight, ocean less-than-container-load freight, and Europe/United States FBA logistics. For partner-carrier services, ZH may arrange the shipment while UPS, DHL, FedEx, EMS, SF, a postal operator, or another destination carrier performs later transport stages.

Official evidence	17TRACK tracking platform

Quick Answer

Enter the shipment number supplied by ZH or the assigned transport partner on the ZH tracking entry, or submit the number to 17TRACK. If no result appears, first remove spaces, verify every character, confirm that you copied a shipment number rather than a marketplace order number, and ask the seller which ZH service or partner carrier was selected.

Pro Tip: A label or electronic shipment record can exist before ZH or a partner carrier physically receives the parcel. Wait for an acceptance or facility scan before treating the shipment as in transit. 17TRACK is an independent tracking platform and cannot change delivery instructions, release customs, approve refunds, or settle claims.

How to Track ZH Packages

Use the identifier shown in the ZH account, shipping label, dispatch confirmation, or merchant shipment record. Tracking may begin with ZH and later show scans from the express, postal, customs, or last-mile organization handling the next stage.

Copy the complete shipment number without adding the marketplace order number.
Open the official ZH website and use its logistics tracking entry.
Paste the identifier and review the newest event, location, timestamp, and named operating carrier.
Alternatively, open 17TRACK, enter the same number, and use automatic carrier detection or select the carrier shown in the shipping record.
If a partner number appears after handoff, retain both identifiers and check the destination carrier’s official tracker as well.

Which Identifier Should You Use?

Identifier	How to use it
Tracking or waybill number	Use this for shipment-event queries. It may be assigned by ZH or by the booked carrier.
Order number	Use it with the seller or marketplace; it is usually not a carrier tracking identifier.
Merchant reference	Use it to locate the order in the merchant’s system, then retrieve the corresponding shipment number.
Partner or last-mile number	Use it after a downstream carrier is named or after a number conversion is displayed.
Delivery notice number	Use it with the destination delivery carrier for pickup or redelivery instructions.

If you received no shipment number, the sender or ecommerce seller must obtain it from the ZH account or booked partner service. If a valid-looking number remains inactive, ask the sender whether the parcel has physically left the warehouse and which carrier is expected to perform the first acceptance scan.

Tracking Number Formats and Examples

ZH offers several service families rather than one universal numbering system. The usable identifier can therefore be a ZH shipment number, an international express waybill, a postal identifier, or a downstream delivery number. Preserve the exact value shown in the shipment record and use the carrier name displayed beside it.

Tracking Number Format

Identifier family

Normalized pattern

ZH shipment identifier

Use exactly as printed; remove only display spaces or hyphens when the tracker rejects formatting.

Issued by	The merchant, marketplace, or order-management system.
Typical service/use	Customer-service lookup and order reconciliation.

Important caveat	Ask the seller to map the order reference to a shipment number before using a carrier tracker.

Tracking Statuses and Meanings

ZH shipments can contain events from several operators. Read the exact event together with the named carrier and location; the newest physical scan is more useful than an electronic pre-advice event.

Average Delivery Days	Use the 3–7-business-day express reference window rather than an unsupported route mean.
Last-Mile Partner / Handoff Carrier	The selected UPS, DHL, FedEx, postal, or contracted destination network shown in tracking.
Customs & Clearance Tips	Use specific commodity descriptions, correct values, HS codes where required, and complete recipient details. Carrier acceptance and customs release are separate events.

Last-Mile Partner / Handoff Carrier	The delivery carrier identified in the shipment record or destination scan.
Customs & Clearance Tips	Ensure the seller applies the correct tax and import-data treatment for the transaction and responds promptly to carrier requests.

Last-Mile Partner / Handoff Carrier	The selected express carrier, postal operator, or contracted delivery network.
Customs & Clearance Tips	Provide VAT, EORI, or marketplace tax data where the destination and shipment type require it. Arrival at an import gateway does not mean customs release.

View all Middle East delivery details

Primary Service Type	ZH dedicated line or international express
Average Delivery Days	Use the service-specific route quote and local customs outcome.
Last-Mile Partner / Handoff Carrier	The carrier named in destination tracking.
Customs & Clearance Tips	Accurate consignee identity, telephone details, invoices, origin markings where required, and product compliance documents can prevent avoidable holds.

ZH publishes route families and a 3–7-business-day reference for listed international express channels, rather than a verified country-by-country historical-average dataset. The table therefore avoids invented averages. Weekends, holidays, peak periods, weather, capacity, remote areas, poor address data, customs, restricted goods, and partner handoffs can move delivery outside the reference window.

Common Tracking Problems and Solutions

Start with the latest physical scan, identify the organization named in that event, and then involve the sender because the ZH account holder usually has the booking record, declaration, invoice, and contractual authority needed to open an inquiry.

Problem & Solution

Problem/status shown

Likely cause

Invalid number

Typing error, order ID submitted, wrong carrier selected, or identifier not yet registered.

View solutions for an invalid number

Who to contact	The seller or ZH account holder first.

No tracking or label created

Electronic booking exists, but the parcel may remain with the sender or origin warehouse.

Check first	Look for an acceptance or facility scan rather than only pre-advice.
Immediate action	Ask the sender for the actual handover date and receipt.
When to escalate	When the promised dispatch date has passed without physical acceptance.
Who to contact	The sender, merchant, or ZH account manager.

View solutions for delivered but not received

Check first	Check entrances, mail areas, lockers, reception, household members, and neighbors.

International Shipping, Customs and Carrier Handoffs

A ZH cross-border parcel may pass from the seller to ZH, an export or express partner, customs authorities, a destination gateway, and a last-mile carrier. Electronic pre-advice, physical custody, customs release, and final delivery are separate milestones.

Delivery Management and Post-shipment Options

Delivery changes depend on the underlying partner carrier, destination, shipment stage, and shipper authorization. ZH’s international express terms show that address correction or re-routing can generate charges and that successful modification is not assured.

Lost, Damaged, Claims, Insurance and Refunds

A tracking inquiry, carrier investigation, compensation claim, postage adjustment, and ecommerce refund are different processes.

Shipping Restrictions

Customer Service

For shipment inquiries, contact the seller or ZH account holder first, then use the ZH business contacts with the shipment record. After a partner carrier records physical receipt, that carrier can address local operational events; ZH remains the contract contact for a service purchased through a ZH account.

Ecommerce and Business Tracking

Merchants should store the order ID, ZH reference, partner waybill, last-mile number, service, and carrier as separate fields. This prevents an order reference from being mistaken for a transport identifier and supports handoff-aware exception monitoring across multiple carriers.

FAQ

1. How do I track my ZH package?

Enter the shipment number on the official ZH website or track it with 17TRACK. Check the newest event for the named carrier because a ZH shipment may transfer to an express, postal, or last-mile partner.

2. Where can I find my ZH tracking number?

Look in the ZH account, shipping label, seller dispatch email, or marketplace shipment record. If you see only an order number, ask the seller for the carrier shipment or waybill number.

3. What does a ZH tracking number look like?

ZH shipments do not use one universal public format because ZH offers dedicated lines and partner services. Use the complete identifier exactly as issued and verify the associated carrier instead of guessing from a prefix.

4. When will the first ZH tracking event appear?

The first physical event appears after ZH, an origin facility, or the selected carrier accepts and scans the parcel. Label creation or electronic pre-advice alone does not prove physical handover.

5. Why is my ZH tracking not updating?

The parcel may be between scan points, consolidated for line-haul, in customs, or awaiting a carrier handoff. Check both the original and partner numbers, then ask the seller to open an inquiry if the shipment exceeds the booked expectation.

6. How long does ZH delivery take?

ZH lists a 3–7-business-day reference for its published UPS, DHL, and FedEx international express channels. Dedicated lines, postal packets, FBA logistics, air freight, and ocean LCL follow route-specific quotations, while customs and exceptions can add time.

7. What should I do after a failed ZH delivery attempt?

Follow the destination carrier’s notice for redelivery or pickup and act before return processing begins. Notify the seller if an address correction, authorization, or charge is required.

8. What should I do if ZH tracking says delivered but I received nothing?

Check entrances, lockers, mail areas, reception, household members, and neighbors first. Then request delivery details from the destination carrier and give its case number to the seller or ZH account holder for investigation.

9. How do I report a lost or damaged ZH shipment?

Photograph and retain the parcel, label, contents, and packaging, then report the issue to the delivering carrier and ZH account holder. ZH’s listed UPS, DHL, and FedEx channel terms require claim applications within 30 days after shipment.

10. How do I contact ZH customer service?

Use the official ZH business consultation page, telephone numbers 13711780664 or 13302775023, or the listed WeChat account yyi0295. Prepare the tracking number, booking reference, service, ship date, latest scan, and supporting evidence.

11. Does a partner tracking record mean the partner already has my ZH parcel?

No, an electronic partner record can exist before physical transfer. Responsibility remains with the upstream custodian until the downstream carrier records an acceptance or facility scan.

12. Can a ZH shipment receive a second tracking number?

Yes, a partner express carrier or destination delivery operator may assign another identifier. Keep the original ZH reference and every partner number because support teams may use different identifiers for different transport stages.

13. Who is responsible when a ZH shipment is in customs?

Customs controls the release decision, while the carrier or bonded facility may physically hold the parcel. The sender, recipient, declarant, or broker must provide requested invoices, values, commodity descriptions, tax details, and compliance documents.

14. Is the ZH estimated delivery date guaranteed?

A reference transit range or tracking estimate is not automatically a guaranteed commitment. Only the written terms of the purchased service determine whether a delivery guarantee or refund remedy applies.

15. Can businesses track ZH shipments through an API?

Businesses can use their authorized ZH account workflow and may use the 17TRACK multi-carrier API for supported tracking. Implement only against current provider documentation, and keep order IDs, ZH references, partner waybills, and last-mile identifiers as separate data fields.

Tracking API

Use an official ZH integration only when ZH supplies current account-specific documentation and credentials. For multi-carrier tracking, consult the 17TRACK API documentation. The 17TRACK carrier code for ZH is left as a placeholder below rather than guessed.

# 1. ZH official tracking API
# Use only account-specific API documentation and credentials supplied directly by ZH.
# No unofficial endpoint is included.

# 2. 17TRACK API — register a shipment
curl --request POST \
  --url "https://api.17track.net/track/v2.4/register" \
  --header "17token: YourKey" \
  --header "Content-Type: application/json" \
  --data '[
    {
      "number": "TRACKING_NUMBER",
      "carrier": "CARRIER_CODE"
    }
  ]'

# Replace TRACKING_NUMBER with the shipment identifier.
# Replace CARRIER_CODE only with the verified code from current 17TRACK documentation.
