I am the person in charge of a small and micro enterprise that just started import business. Last month, I handled my first import by myself. Because the small agency I found operated irregularly, the goods got stuck in the customs declaration link after arriving at the port.
Not only did I incur over 8,000 yuan in port detention fees, but I also almost had the goods seized by customs due to non-compliant documents. It took nearly two weeks to resolve, and I wasted a lot of money. Now a new batch of goods will arrive at Shanghai Port next week.
I plan to switch to a professional agency, but I still don't understand how formal import agency customs declaration is done, what key points must be noted in the entire process, and how to avoid the pitfalls I encountered last time. I want to know the complete operation standards clearly to avoid problems again.

The first step of formal import agency customs declaration is pre-document review. Before the goods are shipped，the full set of documents are checked，including packing lists，invoices，trade contracts，certificates of origin，import approvals or permits for specially supervised goods，etc. All document information is checked for consistency one by one，and the accuracy of commodity code classification is confirmed. Common issues such as document errors/missing items and classification deviations are identified in advance to avoid delays in customs clearance due to document amendments or cancellations after the goods arrive at the port，which would incur additional port detention fees.
Three working days before the goods arrive at the port，the agency completes the preparation work for pre-declaration. After the goods arrive at the port，the agency completes the document exchange immediately，then sends the formal electronic declaration to the customs. After completing system data entry and tax calculation，the agency assists in completing electronic tax payment in advance to reduce customs clearance waiting time. If the customs triggers an inspection，the agency will connect with on-site inspection arrangements in advance，assist in preparing for container unpacking，and organize corresponding supporting documents to cooperate with on-site inspection work. If no inspection is needed，it will directly wait for customs release.
Regarding contingency plans，corresponding response plans are prepared in advance for common issues such as price assessment doubts，inspection anomalies，and document rectification. If a price assessment dispute arises，price supporting documents are organized and provided immediately to cooperate with negotiations，avoiding long-term detention of goods at the port.
After the goods are released，the agency will organize and archive the full set of customs declaration files to ensure traceable operations throughout the process. At the same time，it will assist in completing subsequent connection work such as foreign exchange payment and input tax deduction to ensure a compliant closed loop for the entire process.

A common anomaly in the import agency customs declaration link is price assessment disputes. If the customs questions the declared price, corresponding price supporting documents need to be provided in a timely manner, including original factory invoices, foreign exchange payment vouchers, insurance documents, transaction records of the same batch of goods, etc. In case of account suspension or document rejection, it is necessary to first check whether there is an error in system information comparison.
After confirming that the document information and declaration information are completely consistent, apply for document cancellation and re-declaration. Under the integrated customs clearance mode, cross-port declaration needs to confirm that the information of the local place and the port is synchronized to avoid information deviations in secondary declarations. All declaration links must have a closed information loop, and every modification at each node must be recorded on file to avoid missing data during subsequent verification.

In the import agency customs declaration link, it is necessary to connect with logistics nodes in advance. After confirming the arrival time of the goods at the port, reserve time for document exchange in advance. If the shipping company skips the container or changes the port, the customs declaration information must be updated immediately and the declaration time adjusted.
For container detention fees and port detention fees, you can apply to the shipping company for an extension of the free storage period in advance to reduce additional costs. When choosing between direct shipping or transshipment plans, it is necessary to consider the time requirements for customs declaration.
If the goods have urgent clearance needs, the direct shipping plan is preferred; if you need to avoid peak clearance to reduce costs, you can choose the transshipment plan. For bill of lading endorsement transfer, it is necessary to confirm the completeness of the endorsement information to avoid affecting the transfer of goods ownership and the customs declaration process.

In the import agency customs declaration link, you can apply for VAT deferment based on the nature of the goods and import qualifications to postpone the time of VAT payment, optimize the company's cash flow, and reduce capital occupation costs. For imported goods in cross-border related-party transactions, it is necessary to complete pricing filing in advance and comply with the arm's length principle to avoid being identified by tax authorities as profit transfer and triggering BEPS-related investigations.
The dutiable value of imported goods must be declared truthfully, including related expenses such as freight and insurance. Avoid underreporting leading to low dutiable value and triggering tax audits. For imported goods where the owner is a non-resident enterprise, it is necessary to pre-accrue income tax in advance and make compliant declarations.

In the foreign exchange payment link after import agency customs declaration, it is necessary to ensure that the foreign exchange receipt and payment information is consistent with the customs declaration form information. For those using CIPS RMB cross-border payment, it is necessary to check the consistency between the message information and the customs declaration information to avoid failure in settlement and account reconciliation due to information errors or omissions.
Foreign exchange receipt and payment through offshore accounts must comply with regulatory requirements to avoid illegal settlement. In the foreign exchange purchase link, you can choose the appropriate time to purchase foreign exchange according to exchange rate fluctuations to optimize the cost of foreign exchange purchase. All foreign exchange receipt and payment operations must retain corresponding transaction vouchers to cooperate with subsequent compliance verification and avoid the problem of account suspension that cannot be reconciled.

Before import agency customs declaration, it is necessary to confirm the terms in the trade contract. For payment by letter of credit (L/C), it is necessary to check for soft clauses in the L/C to avoid refusal of payment due to non-compliance of documents.
The contract needs to add a force majeure clause as a safety net. If customs clearance is delayed due to customs policy adjustments or inspections, responsibilities can be divided according to the clause. For the transfer of goods ownership, it is necessary to confirm the completeness of the bill of lading information.
The letter of guarantee must clearly specify the scope of guarantee and validity period. If the imported goods involve intellectual property rights, it is necessary to complete the customs protection record of intellectual property rights in advance to avoid the goods being seized by customs due to intellectual property disputes and ensure clear ownership of the goods.

After receiving the customs inspection notice, interpret the content of the notice immediately to confirm whether the inspection method is machine inspection or manual container unpacking inspection. It is necessary to check the authenticity of the container seal, confirm that the seal number is consistent with the bill of lading information, and take photos for evidence immediately if the seal is damaged.
For machine inspection, the goods placement information must be sorted out in advance to avoid abnormal machine inspection images caused by messy placement of goods, which may trigger manual inspection. If sample inspection and identification are required, cooperate with customs to take samples and follow up the progress of the test report. If the test result is abnormal, provide corresponding product certification materials immediately to cooperate with subsequent processing.

If the imported goods are dangerous goods, it is necessary to confirm in advance that the UN dangerous goods packaging mark meets the requirements, the packaging complies with transportation and customs clearance standards, complete the dangerous goods classification identification in advance, and prepare compliant MSDS documents. The MSDS must be prepared in accordance with the latest standards in 2026 with complete and accurate information.
For ordinary moisture-proof goods, it is necessary to prepare a moisture-proof reinforcement plan in advance, select appropriate buffer packaging materials to avoid damage to the goods during transportation, which may lead to customs inspection determining the goods as unqualified and affecting the customs clearance process. Packaging information must be declared truthfully to avoid declaration anomalies due to underreporting of packaging attributes.

The rhythm of import agency customs declaration can be adjusted according to inventory conditions. Adopt an inventory linkage strategy to reasonably arrange the arrival time of goods at the port and the customs declaration time to avoid inventory backlog or out-of-stock. You can switch between CIF and FOB trade terms according to actual needs.
Under the FOB term, you can independently choose logistics and customs declaration agents to better control costs and customs clearance rhythm. For enterprises that import for a long time, a cost actuarial model can be built to calculate the customs declaration, logistics, and tax costs of each batch of imports, optimize the supply chain structure, reduce overall import costs, and increase profit margins.
