Reliable sourcing and import agency services.
I am the procurement manager of a foreign trade company and have just taken over the import business segment. Last time, our cooperating freight forwarder missed the additional declaration on the certificate of origin, resulting in the goods being detained by customs. This not only delayed the delivery schedule but also led to a penalty payment.
Now I want to find a professional agency import customs declaration company, and I would like to know the complete customs declaration process, what documents need to be prepared in advance, how to avoid price assessment being questioned, and how to handle subsequent remittance and tax refund. Could you please explain this in detail?

First，it is necessary to clarify the full-chain compliance steps for agency import customs declaration，which must strictly follow customs supervision requirements from pre-preparation to final implementation. Completing document pre-review 3-5 days in advance is the core pre-action. You need to verify the consistency of documents such as commercial invoices，packing lists，bills of lading，certificates of origin (for RCEP items，comply with the latest accumulation rules)，and import licenses. Special attention should be paid to dedicated documents for goods under special supervision，such as health certificates for food products and 3C certification for mechanical and electrical products.
For core node coordination，focus on synchronous verification of manifest and customs declaration data. In 2026，the national customs clearance system has realized automatic manifest comparison. If the bill of lading number，pieces/weight/measurement，and commodity HS code do not match the manifest information，it will directly trigger inspection control. Before declaration，confirm the division of responsibilities corresponding to trade terms，for example，under CIF terms，freight and insurance premiums must be accurately included in the dutiable value to avoid price assessment disputes.
Contingency plans for abnormal situations should be prepared in advance. If customs inspection control is triggered，arrange on-site contact personnel to cooperate immediately and prepare supporting materials such as the original packaging of goods and production records. If price assessment is questioned，provide supporting documents for the transaction price，such as purchase and sales contracts，payment vouchers，and third-party price comparison reports.
Final compliance implementation requires completing three links: tax payment，release and pick-up，and document filing. In 2026，customs has launched an electronic document archiving system. All customs declaration materials must be retained in electronic form for at least 5 years. At the same time，cooperate with subsequent tax verification and foreign exchange verification to ensure consistency of the four flows (contract，invoice，logistics，and capital).

Regarding document review and price assessment disputes, focus on verifying the latest version of the certificate of origin. In 2026, RCEP certificates of origin have added an automatic calculation module for regional value content. If the declared component ratio does not meet requirements, it will directly trigger price assessment. If customs questions the transaction price, provide long-term cooperation agreements with overseas suppliers and price certificates for bulk purchases to prove that the transaction price meets fair market standards and avoid being assessed for dutiable value.

For the international logistics link, prioritize confirming the accuracy of manifest information. In 2026, global port congestion has decreased by 30% compared to 2024, but it is still necessary to lock in shipping space 7 days in advance and apply for a 14-day free storage period and 7-day free container detention period. If port changes or container roll-offs occur, contact the agent immediately to modify bill of lading information and update customs declaration data synchronously to avoid customs declaration delays caused by lagging logistics information. Endorsement and transfer of electronic bills of lading must be completed via the blockchain platform designated by customs to ensure compliance of title transfer.

In terms of tax planning, the VAT deferral policy has covered all national ports in 2026. Imported goods can postpone VAT payment at declaration and complete payment after subsequent sales, effectively reducing capital occupation costs. Note that pricing for cross-border related transactions must comply with the latest BEPS requirements to avoid transfer pricing adjustments by tax authorities. Meanwhile, complete remittances via the CIPS RMB cross-border payment system to avoid exchange rate difference losses.

For cross-border payment and receipt compliance, focus on the authenticity of SWIFT messages. In 2026, customs and the foreign exchange administration have realized real-time comparison of message data. If the payment/receipt amount does not match the customs declaration amount, foreign exchange verification will be triggered. Retain complete trade contracts, payment vouchers, and logistics documents to ensure every capital flow has a corresponding trade background. Additionally, use forward foreign exchange settlement tools to lock in exchange rates and reduce cost risks caused by exchange rate fluctuations.

International trade legal risks should be avoided in advance. Soft clauses in letters of credit must be reviewed before issuing the LC to avoid unenforceable clauses. In case of force majeure events such as port congestion or policy changes, issue a force majeure certificate promptly to claim exemption from liability from overseas suppliers. Title transfer must be completed via a formal Letter of Indemnity (LOI) to ensure legality, and complete customs recordation of intellectual property rights to avoid goods being detained due to infringement.

For on-site inspection, prepare materials such as original goods packaging, production batch records, and component test reports in advance to cooperate with customs in seal identification and container unpacking checks. In 2026, the customs machine inspection system has realized AI automatic identification. If the machine inspection result shows abnormalities, arrange for testing promptly and provide third-party lab reports to prove the actual components of the goods, avoiding increased port detention fees caused by inspection delays.

Packaging for special goods must comply with UN dangerous goods classification standards. In 2026, customs has increased inspection intensity for dangerous goods packaging. Complete MSDS preparation and packaging identification in advance to ensure the UN number and hazard category marks on packaging are clear and accurate. Food products must use dedicated moisture-proof and insect-proof packaging to avoid cargo damage during transportation, and provide a health certificate meeting importing country standards to ensure smooth customs clearance.

For the export tax refund link, ensure consistency of the four flows. In 2026, tax authorities have launched an electronic document filing system. All customs declarations, foreign exchange receipt vouchers, and logistics documents must be uploaded to the system for retention. If a tax inquiry is received, provide complete trade materials promptly to cooperate with tax authorities in completing verification and avoid tax refund delays. For cross-month declarations, pay attention to the deadline and ensure pre-declaration is completed within 15 working days after goods release to avoid late payment penalties.
