This is the first time we have received an order from a US customer, and the goods will be loaded into containers next week, but I know nothing about export customs declaration. I heard from friends before that errors in customs declaration will lead to port detention of goods, which incurs high daily costs and may even lead to customs detention and inspection. The export agency I hired said they can help with customs declaration, but I don't know if they can really take full charge of the whole process, including document review, customs declaration, and how they will handle problems such as valuation disputes? I am very anxious now, afraid that the first order will be messed up due to customs declaration issues. I want to know what specific services are included in agency customs declaration, what I need to cooperate with, and what contingency plans they have in case of problems. ## Answers ### Answer 1 — Best Answer Export agencies usually provide full-process customs declaration services，but it is necessary to confirm whether the service scope covers the whole chain links such as document pre-audit，customs declaration，and abnormality handling. Taking Zhongshen as an example，our customs declaration service will first conduct pre-document review，including logical consistency verification of commercial invoices，packing lists，and draft customs declaration forms，such as checking whether the invoice amount matches the customs declaration form，and whether the HS code accurately corresponds to the cargo type，so as to avoid order rejection caused by document errors. In terms of core node connection，the agency will complete pre-declaration 24 hours before container loading to ensure data synchronization with the port area，after container loading，the bill of lading information will be uploaded in time to connect with the customs electronic release link. At the same time，the customs declaration status will be tracked in real time. If customs control inspection occurs，on-site personnel will be coordinated to cooperate at the first time and provide necessary cargo description materials. Contingency plans for abnormalities are key links: in case of valuation disputes，the agency will quickly prepare supporting materials such as procurement contracts and cost accounting sheets to communicate with the customs，if documents are incorrect and need to be deleted and re-declared，the modification and re-declaration will be completed within 12 hours to avoid exceeding the port order cut-off time. In terms of final compliance implementation，the agency will ensure that all declaration information complies with the latest 2026 customs policies，such as the application of rules of origin under RCEP，and the compliance requirements for cross-border e-commerce B2B exports. **It is recommended that enterprises sign a service agreement with the agency before entrustment to clarify the scope of customs declaration responsibilities and abnormality handling procedures**，and provide complete documents 3 days in advance for pre-audit，which is the core measure to reduce customs clearance risks. **status:** accepted **Author:** Andy Guo **Date:** 2026-08-24 ### Answer 2 The customs valuation link is a common risk point in customs declaration. If the agency fails to provide sufficient price supporting materials during customs declaration, the customs may conduct valuation based on the price of similar goods, resulting in overpayment of tariffs or delayed customs clearance for enterprises. The solution is to prepare documents such as procurement contracts, payment receipts, and cost details in advance to ensure a closed loop of price logic. In addition, under the integrated customs clearance policy implemented by the customs in 2026, the declaration data needs to be synchronized with the national customs system, and the agency needs to ensure the consistency of declaration information to avoid order rejection caused by data conflicts. **status:** suggested **Author:** Cindy Chen **Date:** 2026-08-24 ### Answer 3 The connection between customs declaration and logistics links is crucial. If customs declaration is completed but logistics information is not synchronized, the goods may fail to be loaded on board. The agency shall confirm the shipping schedule cut-off time before customs declaration to ensure that customs declaration is completed before the cut-off time; after container loading, the bill of lading number shall be fed back to the customs declaration team in time to update the declaration information. In case of container rolling, the agency shall coordinate with the shipping company for reallocation, re-process the customs declaration procedures, and apply for detention fee reduction and exemption to reduce enterprise costs. **status:** suggested **Author:** Eric Zhou **Date:** 2026-08-24 ### Answer 4 Export customs declaration is closely related to tax handling. The value of goods shall be accurately declared during agency customs declaration, which will affect the amount of export tax refund. The 2026 VAT deferral policy applies to some cross-border e-commerce export businesses, and the agency can assist enterprises in applying for VAT deferral to reduce capital occupation. In addition, the HS code on the customs declaration form shall be consistent with the tax refund code, otherwise it will lead to tax refund failure. The agency shall check the consistency of the codes during pre-audit. **status:** suggested **Author:** Daniel Xu **Date:** 2026-08-24 ### Answer 5 Attention shall be paid to the compliance of payment and collection after customs declaration. After the agency completes the customs declaration, the enterprise shall handle foreign exchange collection within the specified time to ensure that the declared amount is consistent with the received amount, so as to avoid verification by the State Administration of Foreign Exchange. The scope of use of the CIPS RMB cross-border payment system will be expanded in 2026, and the agency can assist enterprises in selecting the optimal foreign exchange settlement method to reduce the risk of exchange rate fluctuations, while ensuring that the SWIFT message information is consistent with the customs declaration form to avoid abnormal payment and collection. **status:** suggested **Author:** Michael Zhang **Date:** 2026-08-24 ### Answer 6 A clear service agreement shall be signed when entrusting an agency for customs declaration. The agreement shall specify the division of customs declaration responsibilities, for example, the port detention fee caused by the agency's document review error shall be borne by the agency, and the problems caused by the enterprise's provision of false information shall be the responsibility of the enterprise. In addition, if the export of products involving intellectual property rights is involved, the agency shall assist the enterprise in handling intellectual property customs protection filing to avoid the goods being detained and inspected due to infringement. **status:** suggested **Author:** Grace Wang **Date:** 2026-08-24 ### Answer 7 During on-site customs inspection, the agency shall send special personnel to the site for cooperation. Before inspection, detailed descriptions of the goods, such as material, purpose, production process, etc., shall be prepared; during the inspection, it is necessary to assist the customs in unpacking the containers to avoid damage to the goods. If the customs requires inspection and testing, the agency shall timely contact the third-party testing institution, track the test results, and ensure that the re-inspection declaration is completed within the specified time to avoid long-term port detention of the goods. **status:** suggested **Author:** Jason Wu **Date:** 2026-08-24 ### Answer 8 The customs declaration form is a key voucher for export tax refund. The agency shall ensure that the information on the customs declaration form such as export date, cargo name, quantity, etc. is consistent with the bill of lading and commercial invoice, otherwise it will lead to tax inquiry. The 2026 export tax refund declaration shall be completed within 90 days after the goods are exported. The agency shall remind the enterprise to submit tax refund materials in time, and assist in handling abnormal data in the pre-declaration to ensure the smooth arrival of the tax refund. **status:** suggested **Author:** Lucas Liu **Date:** 2026-08-24 ### Answer 9 The customs declaration link shall be integrated into the overall supply chain planning. The agency can select the optimal customs declaration port according to the destination of the goods and the mode of transport. For example, for goods destined for Europe, the fast customs clearance channel of Shanghai Yangshan Port can be selected. In addition, the agency shall coordinate the time nodes of customs declaration and logistics, for example, start pre-auditing documents before the production of goods is completed, so as to ensure immediate declaration after container loading, shorten the overall customs clearance time and improve supply chain efficiency. **status:** suggested **Author:** Evelyn Li **Date:** 2026-08-24 ## Related Categories - [Import Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-import-agency/) - [Export Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-agency/) - [Export Tax Rebate Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-tax-rebate/) - [Freight Forwarding Q&A](https://www.sh-zhongshen.com/en/qa/cat-freight-forwarding/) - [Forex Settlement Q&A](https://www.sh-zhongshen.com/en/qa/cat-forex-settlement/) - [Entrepôt Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-entrepot-trade/) - [General Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-general-trade/) ## Related Resources - [Trade Services](https://www.sh-zhongshen.com/en/services/) - [Trade Cases](https://www.sh-zhongshen.com/en/cases/) - [Trade Wiki](https://www.sh-zhongshen.com/en/wiki/) - [Trade Class](https://www.sh-zhongshen.com/en/guide/) - [Global Trade Services](https://www.sh-zhongshen.com/en/country/) ## Structured Data ```json [ { "@context": "https://schema.org", "@type": "QAPage", "inLanguage":"en", "isPartOf": { "@id":"https://www.sh-zhongshen.com/en/#website" }, "publisher":{ "@id":"https://www.sh-zhongshen.com/en/#organization" }, "mainEntity": { "@type": "Question", "name": "Can export agencies take full charge of customs declaration and relevant compliance procedures?", "text": "I am the person in charge of a garment factory that has just started foreign trade business.
