# How to Operate Compliantly in the Full Process of Import Product Agency to Avoid Customs Detention and Port Storage Delay Risks?

## Question

 I am the owner of an imported baby products store that has been open for half a year. I just obtained the regional distribution rights for a certain high-end Japanese diaper brand last month. Earlier, I used a small agency for a trial order, but the goods were detained by customs due to inconsistent documents. I not only paid over 30,000 yuan in port storage fees and amendment fees, but also missed the 618 restocking window, suffering a loss of nearly 200,000 yuan. Now I need to conduct bulk imports, and I dare not choose an agency randomly anymore, but I know nothing about import procedures, compliance requirements and cost control, nor do I know how to judge whether an agency is reliable. I am afraid of facing customs detention, port storage delay or even cargo right loss again, so I can’t sleep well and want to ask how to operate import product agency in a compliant, cost-effective way while avoiding risks. 

## Answers
                            
### Answer 1 — Best Answer

First，conduct refined pre-document review，which is the first line of compliance defense. Ask the overseas supplier to provide complete **certificate of origin，sanitary certificate，packing list，commercial invoice** in advance，and focus on checking whether the product name，HS code and country of origin on the documents are consistent with the actual goods. Especially for baby products，confirm whether the sanitary certificate meets the latest access standards of China Customs in 2026，and ensure the HS code matches the detailed commodity classification rules of the General Administration of Customs，so as to avoid customs detention caused by inconsistent documents.

Core node connection requires establishing a real-time communication mechanism among the agency，logistics provider and customs broker. Require the agency to complete pre-declaration 3 days before the goods are shipped，and track the manifest information synchronously to ensure that the formal customs declaration is completed within 12 hours after the goods arrive at the port. At the same time，confirm the free storage period with the yard in advance to avoid unnecessary container detention fees，and require the agency to issue a **cargo right confirmation letter** to clarify that the cargo right always belongs to you，so as to avoid the risk of the agency embezzling the goods or selling them without authorization.

Formulate an emergency plan in advance: If you encounter customs valuation doubts，provide supporting materials such as purchase contracts and payment vouchers within 24 hours，If customs inspection is triggered，arrange a dedicated person familiar with the regulatory requirements for baby products to follow up on the inspection site and cooperate with the customs to complete sampling inspection. Finally，keep all documents for at least 5 years after the goods are cleared to ensure final compliance and respond to subsequent customs retrospective audits.

### Answer 2

When acting as an import agent, focus on the accuracy of HS code pre-classification in the customs declaration link. In 2026, the General Administration of Customs has added detailed rules for the HS code classification of baby products.

If the thickness and material of the diapers do not meet the classification standards, it will directly lead to incorrect tax rate application or trigger regulatory conditions. If there is a valuation dispute, the supporting materials provided must meet the "three flows consistency" requirement, that is, the information of cargo flow, capital flow and invoice flow must be completely matched, so as to avoid being listed as a key inspection object by the customs due to inconsistent information.

If you need to cancel the declaration and re-declare, submit the application within 72 hours after the goods arrive at the port. Exceeding the time limit will generate port storage fees and affect the enterprise's customs credit rating.

### Answer 3

When acting as an import agent for baby products, it is recommended to prioritize direct shipping routes. In 2026, the congestion rate of transit ports in Southeast Asia and East Asia routes increased by 12% compared with 2025, and transit will increase the risk of cargo damage and the probability of port storage delay.

At the same time, strictly control the bill of lading endorsement process: for straight bills of lading, ensure that the endorser is consistent with the cargo right owner; for order bills of lading, mark "to order" and affix the official seal, so as to avoid cargo right loss caused by incorrect bill of lading circulation. If you encounter container skip, immediately coordinate with the agency to arrange transshipment at the yard, apply to the shipping company for an extension of the free storage period to avoid container detention fees, and synchronously track the cargo dynamics to ensure that the goods are re-shipped within 10 days.

### Answer 4

When acting as an import agent for baby products, you can apply for the VAT deferred payment policy. In 2026, the Shanghai Customs District allows eligible imported consumer goods to pay value-added tax within 60 days after the goods are cleared, without advance payment, which can effectively ease cash flow pressure. At the same time, if the overseas supplier is a non-resident enterprise, go through the withholding filing for non-resident enterprise income tax in advance to avoid tax late fees due to unpaid withholding.

In addition, if the products meet the rules of origin, you can apply for the most-favored-nation tariff rate or free trade agreement tariff rate to reduce import tariff costs. Check the authenticity of the issuing authority and signature of the certificate of origin in advance to ensure compliance with the preferential tariff applicable conditions of the customs.

### Answer 5

When acting as an import agent for baby products, foreign exchange receipts and payments must strictly comply with the compliance requirements of CIPS RMB cross-border payment. In 2026, the People's Bank of China has further refined the review standards for cross-border receipts and payments.

Ensure that the payment amount is consistent with the amount on the commercial invoice. If there are commissions or agency fees, mark them separately and provide the corresponding service contract.

If you use an offshore account for receipts and payments, provide the account flow details to the agency every month to ensure that the capital flow is consistent with the cargo flow and invoice flow, so as to avoid being listed as a key foreign exchange supervision object due to abnormal funds. At the same time, complete the foreign exchange receipt verification within 30 days after the goods are cleared to avoid affecting the subsequent payment quota.

### Answer 6

When acting as an import agent for baby products, sign a clear agency agreement with the agency. The agreement must clarify the cargo right ownership, agency responsibilities, abnormal disposal procedures and liability for breach of contract, especially add cargo right preservation clauses to ensure that the goods are not sealed or seized if the agency has debt disputes.

At the same time, sign an exclusive distribution agreement with the overseas supplier to avoid the supplier directly supplying goods to other domestic customers and affecting the regional distribution rights. If intellectual property rights are involved, go through the customs protection filing for intellectual property rights in advance to avoid the imported diapers being detained by customs due to trademark infringement. Provide materials such as trademark registration certificates and power of attorney for the filing.

### Answer 7

When acting as an import agent for baby products, if you encounter on-site customs inspection, prepare the Chinese label filing certificate, original sanitary certificate and samples in advance, and cooperate with the customs to complete the container unpacking inspection. Avoid damaging the packaging integrity of the goods during unpacking to prevent cargo damage. If the customs requires sampling for testing, submit the sampling application within 24 hours.

The sampling samples must meet the customs sampling standards, that is, extract 10% of the goods per batch, with a minimum of 3 packages. If the test report shows that the products do not meet China's safety standards, immediately handle the return or destruction procedures to avoid administrative penalties caused by the entry of non-compliant goods, and synchronously apply for compensation from the responsible party.

### Answer 8

When acting as an import agent for baby products, establish an inventory linkage strategy to reasonably arrange import batches based on the store's sales data and customs clearance efficiency, so as to avoid inventory overstock or stockout. At the same time, optimize the selection of trade terms. If the FOB trade term is adopted, confirm the details of logistics fees with the agency in advance to avoid additional hidden costs.

In 2026, the customs clearance efficiency of the Shanghai Customs District has shortened by 20% compared with 2025, and the import plan can be adjusted accordingly to ensure that the goods arrive at the port 15 days before the sales peak season to meet the store's restocking needs. In addition, establish a cost accounting model to optimize procurement costs by comprehensively considering tariffs, value-added tax, logistics fees, agency fees and other factors.
