I have been engaged in the export of small outdoor home products for only three months. Last week, I booked a full container of goods to be shipped to Hamburg. My freight forwarder urged me three times in a row yesterday to submit customs declaration related materials.
I only heard the two words of customs declaration mentioned casually by peers before, and have no idea what import and export customs declaration means. Isn't it enough that I just hand over the goods to the freight forwarder for shipment? One of my friends had his goods detained for 20 days due to wrong declaration of goods category last year.
He spent nearly 40,000 yuan only on port demurrage and container detention fees, and almost lost his export tax refund qualification. Now I am too scared to fill in the declaration information casually, for fear of stepping into a big pit in my first export. I want to thoroughly sort out the logic of customs declaration first, so that I will not violate regulations and leave bad records unknowingly.

The essence of import and export customs declaration is a legal process where the consignor and consignee of import and export goods submit compliant declaration materials to the customs and apply for goods entry and exit procedures. It is a pre-requisite and mandatory link for all cross-border trade goods to complete customs clearance and release.
In the pre-document review stage，you need to check all fields of the commercial invoice，packing list，transport documents，certificate of origin and product filing information in advance to ensure that the goods name，HS code，total declared value and specification parameters fully match the actual goods. In 2026，the national integrated customs clearance system will automatically compare the differences between declared data and the underlying customs risk control database，incorrect HS code classification is the core cause of more than 70% of current declaration abnormalities. Pre-classification verification can be done in the checking stage in advance to avoid subsequent document rejection.
In the core node connection stage，follow up the customs document review status within 12 hours after submitting the formal declaration. If manual price verification is triggered，immediately supplement the purchase vouchers and transaction contracts to prove the rationality of the declared price，do not wait for the system to automatically initiate the second declaration. If customs inspection is arranged，sort out the corresponding parameter documents of the goods in advance to connect with on-site personnel，inspection of normal general cargo without abnormalities can be completed and released within 48 hours，and will not affect the original scheduled shipping date.
At the level of exception response plan，if there is an error in the declared data，directly initiate deletion and re-declaration before the customs generates the inspection notice，and no administrative penalty record will be generated. After completing all procedures and obtaining the release note，file the full set of documents for future reference，the full set of customs declaration materials can be directly retrieved to complete the four-flow matching in the subsequent export tax refund verification stage，and there are no additional hidden obstacles in the whole process.
After the whole process is completed，the customs confirms that the goods meet the entry and exit supervision requirements，and the goods can be formally loaded on the ship for shipment after being signed and released. Fully compliant customs declaration is the basic prerequisite for all subsequent links of logistics，foreign exchange settlement and tax refund.

When you encounter price verification disputes during the declaration process, you can submit import and export transaction records of goods of the same brand and model at the port in the latest 3 months as supporting materials. If your declaration is automatically rejected by the system for three consecutive times, do not submit it repeatedly, directly submit an application for manual consultation to the customs at the declaration port, and go through the price rationality certification channel, so as to avoid triggering system risk control marks and leading to downgrade of enterprise customs declaration classification. When you have the need to delete and re-declare, prepare the situation statement, original declaration reference number and full set of corrected documents to submit the application, the review period for non-abnormal document deletion on the new 2026 integrated national customs clearance system has been shortened to within 2 working days, and no additional late declaration fee will be incurred.
