I am engaged in cross-border home goods export. After expanding to European and American markets this year, 10 containers of goods I shipped last month were detained at Shanghai Port due to the missing scanned copy of the certificate of origin, resulting in nearly RMB 20,000 of port demurrage fees.
Now I have two new batches of goods to declare for customs, and I am completely confused about the material differences between general trade, cross-border e-commerce 9610 and dangerous goods shipments, fearing that I will miss a key document and run into problems again. I need to clarify all the mandatory customs declaration materials under different trade modes and special scenarios, as well as precautions for advance preparation, to avoid falling into compliance pitfalls again, and ensure fast customs clearance of my goods.

Core customs declaration documents are divided into general basic documents and scenario-specific supplementary documents，which are broken down in full-link logic as follows: Three core documents including commercial invoice，packing list and ocean/air waybill shall be reviewed in the pre-procedure stage，to ensure that the product name，quantity and amount on the invoice are fully consistent with the packing list，and the consignee information on the bill of lading matches the trade contract，the pre-filled customs declaration form shall be submitted simultaneously at the core node. The 2026 customs system has stricter verification rules for electronic documents，so pre-review of electronic data shall be completed 1 day in advance to avoid field errors. For special trade types，general trade requires supplementary certificate of origin and commodity inspection clearance form，cross-border e-commerce 9610 requires submission of filing list form，dangerous goods require UN packaging certificate and MSDS report. For exception handling，if documents are temporarily missing，an electronic letter of commitment can be submitted first to apply for pre-clearance，and the paper documents shall be supplemented within 3 days，with the maximum duration no more than 7 days. Finally，the status of the electronic customs declaration form shall be confirmed within 12 hours after customs clearance，to prevent obstacles in subsequent tax refund and foreign exchange settlement procedures.

Core document verification shall comply with the 2026 customs electronic verification rules. The commercial invoice shall mark 6-digit or more detailed HS codes, the packing list shall specify the exact gross weight and volume of each package, and the bill of lading shall show "to order" or the specific consignee name without ambiguous expressions. At the pre-declaration stage, the pre-review function of the Electronic Port can be used to check field errors in advance, to avoid rejection due to non-compliant document formats.
For special trade types such as Cross-border E-commerce B2B Direct Export (9710), supplementary transaction vouchers from the cross-border e-commerce platform are required, and the official original scanned copy of the certificate of origin issued by authorized institutions shall be submitted. The Electronic Port system will automatically verify the authenticity of the certificate, and any fake certificate will directly trigger cargo detention.。
