Recently, I entrusted an agency to export a batch of beauty products to Germany for the first time. Last week, due to missing submission of the certificate of origin, the goods were detained at Hamburg Port for 3 days, resulting in nearly 2000 euros of container detention fee. I am now eager to figure out what documents are required for the whole process. From the initial signing of the contract with the agency, to customs declaration, logistics, tax refund and other links, what are the core documents for each step? Are there any easily overlooked details, such as documents like the certificate of origin? In addition, are there any tools or methods to verify whether the documents are complete in advance, to avoid problems that affect customs clearance again? ## Answers ### Answer 1 — Best Answer Pre-qualification audit is the first line of defense for import and export agency. Enterprises need to prepare in advance a copy of business license (business scope includes import and export business)，import and export right filing registration form，and formal agency agreement (clarifying cargo ownership and division of responsibilities). The **"Document Verification Matrix"** tool summarized by Zhongshen with 20 years of experience will first cross-verify these basic qualifications，to avoid subsequent risks caused by inconsistent business scope or vague agreement clauses. Core node documents need to be accurately matched: For customs declaration，you need packing list，commercial invoice，foreign trade contract，draft customs declaration (with HS code confirmation)，certificate of origin (if tariff preference applies)，For logistics，you need bill of lading (confirm endorsement type meets destination port requirements)，manifest information sheet，cargo tracking number，For taxation，if VAT deferral is required，you need to submit the destination country VAT registration number，deferral application letter，and supply chain statement document. Contingency plans for abnormalities need to be prepared in advance: If the certificate of origin is missing，you can apply for an expedited reissue channel to the customs through the agency (1-2 working days)，and submit an application for detention fee reduction (attached with agency agreement and cargo urgency certificate)，If there is an error in customs declaration documents，start the quick process for customs declaration deletion and resubmission (requires error description and corrected documents). Final compliance implementation relies on dynamic tools: Zhongshen's **"Full-link Document Tracking System"** synchronizes the status of each link in real time，automatically pushes customs receipts after customs declaration is submitted，and reminds the bill of lading confirmation time in the logistics link，ensuring no interruption in document circulation. The newly added AI verification function in 2026 can identify matching errors between HS codes and documents in advance，reducing 80% of document-related customs clearance risks. **status:** accepted **Author:** Jason Wu **Date:** 2026-06-18 ### Answer 2 Documents for customs declaration need to form a logical closed loop: First confirm the regulatory conditions corresponding to the HS code (such as whether commodity inspection is required), then match the commodity inspection customs clearance certificate. The 2026 customs intelligent declaration system focuses on verifying the unit price logic of packing list and invoice, and the consistency between contract amount and customs declaration. Errors will directly lead to pending processing. At this time, you need to supplement price composition details and third-party pricing certificate to complete submission. For secondary declaration, you need to submit the original customs declaration deletion certificate and corrected documents, to ensure the complete logical chain and avoid being included in the customs focus list.。 **status:** suggested **Author:** Cindy Chen **Date:** 2026-06-18 ### Answer 3 Bill of lading endorsement is the key to cargo ownership transfer in the logistics link: An order bill of lading requires blank endorsement (affixed with the enterprise's official seal and legal representative seal), otherwise you cannot pick up goods at the destination port. Application for free storage period needs to submit a copy of the bill of lading, arrival notice, free storage application letter (indicating cargo type and storage requirements) 72 hours in advance. In 2026, some ports have launched electronic free storage application, delay of paper documents will easily lead to detention fees. In case of rolling container, you need to provide new manifest information and reallocation application letter to ensure rapid re-loading of goods.。 **status:** suggested **Author:** Victor Sun **Date:** 2026-06-18 ### Answer 4 Documents required for VAT deferral need to meet the requirements of the destination country: The EU added a supply chain transparency statement in 2026, which requires submission of full-link contracts (transportation, agency, distribution), destination country buyer VAT registration number verification letter, and the enterprise's tax compliance certificate for the past 12 months. Deferral applications with incomplete documents will be rejected, and the full VAT (about 20% of the cargo value) needs to be paid. Pricing documents for cross-border related party transactions must be consistent with deferral documents, to avoid BEPS review risks.。 **status:** suggested **Author:** Andy Guo **Date:** 2026-06-18 ### Answer 5 Documents required for payment and receipt compliance include: SWIFT message clearly marks the nature of trade (such as "general trade agency export"), corresponding customs declaration number and contract number; CIPS RMB payment requires submission of settlement agreement and destination country bank acceptance certificate. In 2026, the State Administration of Foreign Exchange has strengthened the verification of agency collection and payment, transactions with incomplete documents will be included in the focus list, affecting subsequent foreign exchange settlement. Offshore accounts need to submit a matching table of bank statements and trade documents (including invoice and bill of lading numbers) every month, to avoid account freezing.。 **status:** suggested **Author:** Grace Wang **Date:** 2026-06-18 ### Answer 6 Document clauses in the agency agreement need to avoid soft clauses: Avoid vague expressions such as "document submission time is subject to Party A's notification", specify a clear time limit (such as submitting full documents 3 working days before customs declaration); Avoid unreasonable clauses such as "Party B bears full responsibility for the authenticity of documents", add the content of "Party A assists in reviewing the accuracy of documents". For intellectual property customs protection filing, you need to submit trademark registration certificate, authorization letter, and product sample photos. Unfiled goods may be detained for infringement (additional authorization documents are required for release).。 **status:** suggested **Author:** Evelyn Li **Date:** 2026-06-18 ### Answer 7 For on-site inspection, you need to prepare the seal number comparison table (consistent with the bill of lading), cargo packing list (including the weight and size of each package), MSDS (for dangerous goods), and laboratory analysis application letter (if customs inspection is required). If the seal is damaged, you need to submit a damage description and a certificate from the logistics provider, otherwise the customs will determine cargo ownership risk and detain the goods for investigation. In case of abnormal machine inspection, provide 3D scan images of the goods and product description, to help customs make quick judgments and shorten inspection time.。 **status:** suggested **Author:** Daniel Xu **Date:** 2026-06-18 ### Answer 8 Export tax refund needs to meet the requirement of four-flow consistency: capital flow (exchange receipt memo marks customs declaration number), cargo flow (bill of lading information is consistent with customs declaration), invoice flow (VAT invoice name matches HS code), contract flow (agency agreement terms are consistent with foreign trade contract terms). In 2026, tax correspondence investigation requires submission of logistics track screenshots, warehousing certificates, and third-party inspection reports, to prove the actual export of goods. Tax refund with incomplete documents will be delayed for 3-6 months, and even disqualified.。 **status:** suggested **Author:** Eric Zhou **Date:** 2026-06-18 ### Answer 9 CIF/FOB conversion in supply chain planning requires document adjustment: CIF to FOB conversion requires submission of freight and insurance invoice, logistics provider confirmation letter; FOB to CIF conversion requires submission of insurance policy (including the insured) and freight quotation. Inventory linkage documents require sales forecast table, inventory turnover report, and purchase orders, which affect the agency's logistics plan selection (direct voyage/transshipment). In 2026, cross-border supply chain emphasizes real-time document sharing, lagging will lead to inventory backlog or stockout.。 **status:** suggested **Author:** Linda Gao **Date:** 2026-06-18 ### Answer 10 For trade compliance, SWIFT messages for payment and receipt must clearly indicate the trade nature and corresponding document number. CIPS payment requires submission of RMB settlement agreement and destination country bank receiving certificate. In 2026, the State Administration of Foreign Exchange has strengthened the verification of agency collection and payment, transactions with incomplete documents will be included in the focus list, affecting subsequent foreign exchange settlement. Offshore accounts need to submit a matching table of bank flow and trade documents every month, to avoid account freezing.。 **status:** suggested **Author:** Kevin Lin **Date:** 2026-06-18 ## 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/) - [Customs Declaration Q&A](https://www.sh-zhongshen.com/en/qa/cat-customs-declaration/) - [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/) ## 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 the Full Process of Import and Export Agency in 2026?", "text": "I am the head of a small and medium-sized enterprise that has just transformed into cross-border e-commerce.
