Last month, I entrusted another agent to import a batch of Japanese and Korean beauty products, but the goods were detained for 12 days because I forgot to submit the certificate of origin and Chinese label filing documents. The detention and warehouse fees alone cost over 8,000 yuan, which ate up half a month's profits. Now I want to entrust Zhongshen to handle the import agency for two batches: one is Japanese maternal and infant complementary food, and the other is EU dietary supplements, and we will use RMB cross-border payment and settlement. I'm really afraid of making mistakes again. I want to know what necessary documents I need to prepare for different product categories and cross-border payment scenarios, what details are easy to overlook, and whether I need to prepare any additional filing documents when cooperating with you for the first time. I'm so anxious that I can't sleep, just afraid that something will go wrong again! ## Answers ### Answer 1 — Best Answer Many cargo owners have a common misconception: they think they can complete customs clearance only by preparing three basic documents: bill of lading，commercial invoice and packing list，and ignore the exclusive compliance documents corresponding to different product categories. This is the core cause of more than 80% of customs detention and detention fee cases. If the certificate of origin for maternal and infant complementary food or the **entry goods inspection and quarantine pre-filing certificate** for EU health products is missing，the customs will directly trigger manual examination and detain the goods. The daily warehouse and detention fees for consolidated cargo can reach 1,200-1,800 yuan. If the detention exceeds 14 days，the goods will be auctioned. Not only will you lose the payment for goods，but also your customs credit rating will be affected，and subsequent customs clearance will be listed as a key supervision object. Risk prevention measure: Sort all documents into three categories: basic documents，exclusive category-specific documents and payment and settlement supporting materials，submit them to the agent 7 days in advance，and have the professional team conduct pre-review to ensure consistent information logic and no omissions. Exclusive loss mitigation tip: When cooperating with Zhongshen，you can sign a **pre-review indemnity agreement**. If customs detention and warehouse fees are caused by our pre-review omissions，we will bear 50% of the detention and warehouse fees to minimize your losses. **status:** accepted **Author:** Andy Guo **Date:** 2026-10-05 ### Answer 2 When handling import agency customs declaration, in addition to the three basic documents of bill of lading, commercial invoice and packing list, corresponding supporting documents need to be provided according to customs valuation requirements: If the declared price of the goods is lower than the internal reference price of the customs, you need to provide the original factory purchase contract, payment slip, brand authorization letter, and 3-month cross-border e-commerce platform transaction records of the same product; For used equipment, you need to provide equipment depreciation certificate and overseas third-party inspection report; For donated goods, you need to submit donation agreement and public welfare qualification certificate of the donee. All documents must ensure consistent information logic, especially the correspondence between invoice amount, bill of lading weight, volume and quantity, and declaration elements. If there is a discrepancy, the customs will initiate valuation consultations, which will delay the process by at least 7-10 days, and may even trigger deductive value valuation, resulting in 20%-50% higher tariff payments. **status:** suggested **Author:** Cindy Chen **Date:** 2026-10-05 ### Answer 3 Documents required for import agency logistics links need to match the transportation route and cargo right control requirements: If you choose to transship at a transit port, you need to submit the warehouse agreement of the transit port and the transshipment confirmation letter issued by the shipping company to avoid being identified as falsely declaring the origin without transit certificates; If telex release bill of lading is used, you need to submit the telex release letter stamped with the shipper's official seal in advance, and provide a copy of the consignee's business license to the agent to ensure smooth transfer of cargo rights; For cold chain goods, you need to submit the full-course temperature record and refrigeration equipment inspection report with the goods. If the documents are incomplete, the port cold storage will refuse to accept the goods, resulting in cargo deterioration and losses of more than 30% of the cargo value. In addition, if you apply for an extension of the free detention period, you need to submit the domestic sales contract of the goods to prove that the goods have found buyers, which can improve the approval rate. **status:** suggested **Author:** Evelyn Li **Date:** 2026-10-05 ### Answer 4 Documents for import agency tax compliance need to be prepared according to the tax calculation method: If you apply for VAT deferred payment, you need to provide the enterprise's VAT general taxpayer qualification certificate and domestic sales contract to prove that the goods will be sold domestically without paying import VAT in advance, which can ease the capital pressure; For cross-border related party transactions, you need to submit the related party relationship filing form and transfer pricing contemporaneous documents to avoid the tax authority adjusting the taxable income due to unreasonable pricing, and paying back taxes and late fees; If you enjoy tariff reduction policies, you need to submit the corresponding certificate of origin and tax reduction approval form to ensure the authenticity and validity of the documents. If false declaration of origin is found during inspection, you will not only need to pay back taxes, but also be fined 0.5-3 times the tax amount. In addition, all payment vouchers need to be retained for more than 5 years for tax authority inspection. **status:** suggested **Author:** Lucas Liu **Date:** 2026-10-05 ### Answer 5 Compliance documents required for import agency cross-border payment and settlement: If you use RMB cross-border payment (CIPS), you need to submit the import goods customs declaration form, trade contract and commercial invoice. If the single payment amount exceeds 50,000 US dollars, you need to provide an additional payment explanation detailing the purpose and transaction background of the goods; If you use an offshore account for payment and settlement, you need to submit the offshore account opening certificate and account flow of the past 6 months to prove the legitimacy of the capital source; For advance payment, you need to submit the advance payment filing form and complete the filing on the SAFE digital platform in advance to avoid payment being intercepted due to unfiled, delaying the arrival time of the goods. In addition, all payment and settlement documents must be consistent with the customs declaration form information, especially the goods amount, quantity and counterparty information. If there is a discrepancy, the SAFE will initiate an inspection and suspend the enterprise's payment and settlement authority. **status:** suggested **Author:** Eric Zhou **Date:** 2026-10-05 ### Answer 6 Legal documents required for import agency entrustment: You need to submit the import agency agreement stamped with the official seals of both parties to clarify the cargo right ownership, responsibility division and penalty clauses to avoid subsequent cargo right disputes; For goods involving intellectual property rights, such as branded maternal and infant products and patented health products, you need to submit the brand authorization letter and patent certificate to avoid customs detention due to infringement and loss of cargo value and detention fees; If you use letter of credit settlement, you need to submit the draft letter of credit and review the soft clauses in time, such as "need to submit the inspection report issued by the import country inspection institution", to avoid refusal to pay due to inability to meet the clauses; If the goods are subject to force majeure risks, you need to submit the cargo insurance policy in advance to clarify the insurance scope and ensure smooth claims when the goods are damaged. In addition, all legal documents need to be retained in original for subsequent legal disputes. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-05 ### Answer 7 Auxiliary documents required for import agency on-site inspection: If the goods involve wooden packaging, you need to submit the IPPC mark certificate and wooden packaging fumigation and disinfection certificate to avoid goods being fumigated and delayed for 3-5 days, resulting in additional fumigation fees; For maternal and infant complementary food and dietary supplements, you need to submit the factory inspection report and nutrition composition table with the goods. The customs will check the consistency between the documents and the goods during on-site inspection; For mechanical and electrical products, you need to submit the 3C certification certificate. For products exempt from 3C certification, you need to submit the 3C exemption application form and product manual to prove that the goods meet the exemption conditions; If the goods are found to be inconsistent with the declaration during on-site inspection, you need to prepare actual cargo photos and supplementary purchase contracts in advance to explain the situation to the customs in time, avoid being identified as false declaration and being fined heavily. **status:** suggested **Author:** Victor Sun **Date:** 2026-10-05 ### Answer 8 Documents required for import agency supply chain planning: If you use the bonded warehouse stock mode, you need to submit the bonded warehouse agreement and goods warehousing plan to ensure that the goods can enter the bonded warehouse smoothly and enjoy the bonded policy; If you use the direct mail mode, you need to submit the consignee's ID card copy and order information to meet the personal goods customs clearance requirements and avoid being taxed according to general trade; For multiple batches of imports, you need to submit the import plan and sales forecast data of the past 6 months to allow the agent to optimize the logistics route, select the most cost-effective shipping companies and flights, and reduce transportation costs by 10%-20%; If you choose LCL shipping, you need to submit the detailed packing list of the goods, clarifying the quantity, weight and size of each SKU, to avoid unpacking inspection due to inconsistent LCL data and increasing inspection fees. In addition, all documents must be consistent with the actual goods to ensure the compliance of the entire supply chain. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-05 ## 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": "What core documents are required for full-process import agent customs clearance under general trade mode?", "text": "I am the owner of a small e-commerce business in Shanghai that just started cross-border imports.
