What Core Documents Are Required for the Full Export Process? Do Requirements Differ Across Trade Scenarios?
or complex compliance issues.
clearance and fund security.
I am the head of a small and micro enterprise based in Shanghai, mainly engaged in the export of hardware tools. I just signed two orders last week: one is a traditional foreign trade container order for a German distributor, and the other is a cross-border e-commerce B2B direct mail order for a US buyer.
I used to entrust freight forwarders to handle all documents, but last month I missed the application for FORM A Certificate of Origin, which caused customs clearance delay for the German customer. I not only paid 2000 euros as port storage charges, but also almost lost a long-term cooperative customer, which still makes me shudder when I think about it. I have been looking through materials these days, but the more I read, the more confused I get.
I neither know what core documents need to be prepared for the whole process, nor understand the differences in document requirements across different trade scenarios and target markets, and I am even more afraid of missing any special documents and causing trouble again. My small business really cannot afford such losses, so I hope you can help me sort this out clearly.

Documents required for export customs declaration are divided into basic category and regulatory category: basic documents include commercial invoice, packing list, customs declaration form and bill of lading; regulatory documents are determined according to HS code. For example, if your hardware tools use wooden packaging, you need to provide a fumigation certificate; if they are subject to statutory inspection and quarantine, you need to provide a clearance certificate for exit goods.
Special note: the "Intelligent Audit" system launched by Shanghai Customs in 2025 will automatically verify the HS code matching degree and cargo value rationality of documents. If there is an HS code classification error, the system will directly lock the order, and you need to resubmit a classification opinion, which may cause port delay. Therefore, you need to confirm the accuracy of the HS code through the customs pre-classification inquiry system before customs declaration to avoid unnecessary delay.

Core documents in the logistics link include ocean bill of lading (or air waybill), packing list and commercial invoice. If it is less than container load (LCL) cargo, you also need to provide an LCL distribution order. For cargo to European and American markets, if FOB terms are adopted, you must clearly mark "Freight Collect" on the bill of lading to avoid the freight forwarder mistakenly filling in "Freight Prepaid" which leads to the customer's refusal to pay freight; if the cargo is dangerous goods, you need to provide MSDS report and dangerous goods packaging certificate, and the UN number and dangerous goods class must be displayed on the bill of lading.
In addition, starting from 2026, Port of Hamburg in Germany and Port of Los Angeles in the US require submission of Cargo Tracking Note (CTN/ENS) 48 hours before cargo departure. If not submitted on time, the cargo will be refused entry to the port, and the container detention fee and port storage fee incurred will be borne by the shipper.

For cross-border e-commerce B2B export, if you adopt the "9610" mode, you need to additionally provide order screenshots from the cross-border e-commerce platform and shipping labels; if you adopt the "1210" bonded warehouse mode, you need to provide bonded warehouse outbound order and warehousing agreement.
Special note: the "immediate collection and immediate refund" policy for export tax refund implemented in Shanghai in 2026 requires "Four-Flow Consistency" (contract flow, capital flow, goods flow, invoice flow) of documents. If there is inconsistency, you will not be able to enjoy fast tax refund, and the application will enter the manual review link, and the tax refund cycle will be extended to more than 30 days.

Documents required for export foreign exchange settlement include commercial invoice, electronic record of customs declaration, transaction contract and foreign exchange receipt slip. If it is advance payment, you need to file it in the "Trade Credit Financing System" of the State Administration of Foreign Exchange in advance. For foreign exchange settlement for European and American markets, if the customer uses SWIFT wire transfer, the customer's bank account number, SWIFT code and remittance purpose must be clearly marked on the documents; if the customer uses RMB cross-border payment (CIPS), you need to provide CIPS message receipt.
Special note: the State Administration of Foreign Exchange strengthened the supervision of abnormal foreign exchange settlement in 2026. If the difference between the cargo value on the document and the received foreign exchange amount exceeds 5%, it will trigger a foreign exchange early warning, and you need to submit a difference description and relevant supporting materials, otherwise your foreign exchange settlement right will be restricted.

From the perspective of legal compliance, commercial invoice, transaction contract and bill of lading are core legal documents in export, and all clauses must comply with Incoterms 2024. For traditional foreign trade orders from German customers, if CIF terms are adopted, the insurance policy number and insurance amount (at least 110% of the cargo value) must be clearly marked on the bill of lading; for cross-border e-commerce B2B orders from US customers, the words "Cross-Border E-Commerce B2B Transaction" must be clearly marked on the commercial invoice to avoid being regarded as a general trade order and incurring additional tariffs.
In addition, if there are vague expressions in the documents, such as "approximate quantity" and "approximate cargo value", it may lead to customer's refusal to pay or trigger trade disputes. All clauses must be clear, definite and unambiguous.

Documents focused on in export tax refund audit include tax refund copy of customs declaration, commercial invoice, foreign exchange receipt slip and export goods outbound order. You need to ensure that the date, cargo value and product name on the documents are completely consistent. In 2026, export tax refund audit in Shanghai adopts the "big data comparison" mode, which will automatically compare customs declaration data with invoice data in the tax system and foreign exchange receipt data in the foreign exchange system.
If there is inconsistent data, it will trigger tax correspondence inspection, and you need to provide relevant supporting materials and accept on-site inspection. Special note: documents must be kept for at least 5 years. If you cannot provide complete documents during the audit, the already refunded tax will be recovered, and you may face a fine.

From the perspective of the whole supply chain, export documents need to form a closed loop with documents from procurement, production and logistics links, including procurement contract, production material requisition form, finished product warehouse receipt and logistics consignment note.
For traditional foreign trade container orders, you need to prepare the draft of commercial invoice and packing list when the goods are put into warehouse, to avoid errors caused by temporary modification before shipment; for cross-border e-commerce B2B direct mail orders, you need to automatically connect platform order data with shipping label data to realize real-time generation and synchronization of documents. The "Digital Supply Chain Collaboration" platform launched in Shanghai in 2026 can realize document sharing among foreign trade enterprises, freight forwarders, customs and taxation authorities, reduce manual input errors, improve document processing efficiency and reduce compliance risks.
