China customs cargo hold problems can quickly create storage, demurrage, missed delivery and contract-default costs for U.S. and European companies. When a shipment is inspected, detained or not released, the first task is to identify the actual legal or documentary reason, preserve the customs and logistics record, and coordinate the importer, exporter, customs broker, carrier and warehouse before charges escalate.

Why cargo may be held by China Customs
- the product description, value, quantity or HS classification is inconsistent;
- required licenses, certificates of origin, inspection or quarantine documents are missing;
- the declared consignee, consignor or trade mode does not match the supporting documents;
- Customs requests inspection, sampling, valuation evidence or additional technical information;
- the goods may be restricted, prohibited or suspected of intellectual-property infringement;
- duties, taxes or a required security have not been paid or provided.
Immediate response checklist
- Obtain the written notice, system message or broker explanation and identify the responsible customs office.
- Freeze inconsistent communications and appoint one response coordinator.
- Collect the contract, invoice, packing list, bill of lading, declaration, licenses, origin documents and product specifications.
- Compare the declared data with the goods and commercial transaction before submitting corrections.
- Record storage, demurrage, container and warehouse deadlines.
- Notify the carrier, insurer and contractual counterparty where required.
- Assess whether amendment, supplementary evidence, security, re-export, administrative review or another procedure is available.
Do not amend documents without a consistent explanation
A rushed correction can create a second inconsistency. Under China’s Customs Law, declarations and supporting documents must be accurate, and accepted declarations generally require a valid reason and approval before amendment or withdrawal. Review the commercial documents, payment record, product data and logistics instructions as one evidence set.
Who bears storage and demurrage?
The answer depends on the sales contract, Incoterms® rule, freight-forwarding agreement, carrier tariff, cause of the hold and each party’s conduct. Preserve invoices and notices, challenge unsupported charges promptly, and document reasonable mitigation. A customs hold does not automatically decide contractual liability between buyer and seller.
Representative scenario: classification evidence arrives too late
Representative scenario, not a specific client result: a European buyer’s machinery shipment is held because the invoice description is broad and the broker used a classification inconsistent with the technical manual. While the parties debate responsibility, container charges accumulate. A coordinated submission containing specifications, intended use, transaction documents and a reasoned classification position can be more effective than separate emails from multiple parties.
