Can import and export enterprises meeting customs qualification requirements complete the whole-process customs declaration and clearance independently?
or complex compliance issues.
clearance and fund security.
I am the head of an enterprise mainly engaged in precision machinery import and export based in Shanghai. Last week, our cooperative customs declaration agency misclassified the HS code of our precision grinding tools worth 800,000 RMB, resulting in the goods being detained at Yangshan Port for 3 days.
We not only paid 18,000 RMB port storage fee, but also compensated 12,000 RMB penalty to our German client. Now the agency has suddenly raised the customs declaration fee by 15%, which I can no longer tolerate. I want to handle customs declaration with our own company, but I am not sure: we have formal import and export operation rights, can we complete the whole-process customs declaration independently?
Will more serious problems occur because we are not familiar with new customs regulations and operation procedures, such as longer port detention and customs hold caused by document errors and omissions, or being penalized by customs for failing to meet hidden qualification requirements? We have an urgent order to ship to Munich next Wednesday, we are anxious to finalize the plan and feel very confused and anxious.

First of all，the new 2026 customs regulations clearly stipulate that enterprises holding valid import and export operation rights and completing customs declarer registration with customs can complete the whole-process customs declaration independently. Pre-document review needs to focus on: first，accurate matching of HS codes. You need to check against the 2026 edition of Customs Import and Export Commodity Classification Catalogue，verify one by one based on the product's technical parameters，use and material，to avoid triggering machine inspection alarm due to code error，second，the "consistency of three documents" of certificate of origin，commercial invoice and packing list. You need to ensure that the font and format of value，quantity and shipping mark fully comply with the entry specifications of the customs electronic port system. The system added an AI intelligent verification function in 2026，any minor deviation will be intercepted.
Connection of core nodes needs to be completed simultaneously: first，upload electronic documents on the "Single Window" 24 hours in advance to trigger customs pre-audit，if you receive a pre-audit alarm，you need to complete modification and resubmit within 4 hours，second，complete manifest confirmation 6 hours before cargo arrival at the port，to ensure that manifest information fully matches the cargo name and weight on the customs declaration. Yangshan Port has realized real-time linkage between manifest and customs declaration in 2026，inconsistent information will directly lock the container.
Contingency plans for abnormalities need to be prepared in advance: if abnormal result occurs in customs machine inspection，you need to submit product technical specifications and third-party test reports to the on-site inspection department within 1 hour，and arrange a product-familiar specialist on standby to cooperate with inspection at any time，if there is a code dispute，you can use the classification consultation channel on the "Single Window". Customs added a 12-hour response fast consultation service in 2026 to avoid port detention.
For final compliance implementation，you need to complete document filing within 10 working days after customs clearance，including customs declaration receipt，manifest copy and original certificate of origin，to meet the requirements of subsequent customs audit，it is recommended to regularly check customs declaration data through the compliance self-inspection module on the "Single Window" every month，and correct potential compliance risks in time.

According to 2026 customs regulations, enterprises can conduct self-customs declaration only after completing customs declarer registration and obtaining the Registration Certificate of Customs Declaration Unit. Unregistered enterprises cannot operate independently even if they have import and export operation rights. If HS code error occurs during self-customs declaration, you need to submit a modification application within 2 hours after customs issues the Customs Declaration Modification/Cancellation Notice. Customs has simplified the deletion and re-declaration process in 2026, qualified applications can be approved within 4 hours, but you need to submit the Code Error Description affixed with the enterprise's official seal and product technical parameter certificate. In addition, you need to pay attention to the newly added "related party transaction price verification" rule in the price verification process in 2026. If the deviation between the self-declared cargo value and the customs reference price exceeds 10%, you need to provide supporting materials such as purchase contracts and payment vouchers, otherwise a price verification dispute will be triggered.

When conducting self-customs declaration, you need to pay attention to the linkage between logistics nodes and customs declaration processes at the same time. In 2026, Yangshan Port provides an extra 1-day free storage period for self-declaring enterprises, but you need to complete the binding confirmation of customs declaration and manifest on the "Port Logistics Service Platform" in advance. If container detention fee is incurred due to customs declaration delay, the enterprise can apply for reduction or exemption from the shipping company with the Customs Declaration Abnormality Certificate issued by customs. Shipping companies have uniformly recognized the validity of this certificate in 2026. In addition, if port change or transshipment is required, self-declaring enterprises need to modify the customs declaration within 12 hours before cargo departure, and update the manifest information synchronously, to avoid title risk caused by inconsistent cargo and documents. It is recommended to use electronic bill of lading for title transfer. Shanghai Port has realized full-process electronic circulation of electronic bills of lading in 2026.

Enterprises conducting self-customs declaration need to pay attention to the intellectual property customs protection filing of goods. Customs has realized real-time comparison of intellectual property filing information with customs declarations in 2026. If the goods involve unfiled intellectual property rights, they will be detained until the enterprise provides an intellectual property authorization certificate. In addition, if the enterprise uses a standard contract for self-customs declaration, it needs to ensure that the contract includes a customs declaration liability clause, clarifying the compliance responsibility for customs declaration operations, to avoid contract breach risk caused by customs declaration errors. If customer claim is caused by self-customs declaration, the enterprise can use the Customs Declaration Compliance Certificate issued by customs as the basis for liability exemption, but it needs to ensure that the certificate is issued before the claim event occurs.

In 2026, customs on-site inspection has added a "Focus List" for AI machine inspection. If the goods declared by the self-declaring enterprise belong to the products on the list, the enterprise needs to prepare materials such as product technical specifications and test reports in advance.
In case of devanning inspection, the enterprise needs to arrange a product-familiar specialist to be present, cooperate with customs inspectors in unpacking, sampling and other operations, to avoid cargo damage caused by improper operation. In addition, self-declaring enterprises need to pay attention to the authenticity identification of seals.
Customs has launched electronic seals in 2026, enterprises can inquire the authenticity of seals through the "Single Window". If abnormal seal is found, it needs to be reported to customs immediately to avoid customs detention risk caused by fake seals.

In 2026, export enterprises conducting self-customs declaration need to ensure the "consistency of four flows", that is, cargo flow, capital flow, invoice flow and customs declaration flow are completely matched. If any flow is inconsistent, the enterprise cannot enjoy the export tax refund policy. Self-declaring enterprises need to complete export tax refund pre-declaration within 5 working days after customs clearance, use the pre-audit module of the "Export Tax Refund Comprehensive Service Platform" to check the consistency of documents.
The platform added an AI intelligent verification function in 2026, which can automatically compare the information of four flows. If a warning occurs in pre-audit, correction needs to be completed within 3 working days, otherwise the progress of formal declaration will be affected. In addition, the enterprise needs to keep documents such as customs declaration receipt, bill of lading and VAT invoice on file for at least 5 years, to ensure compliance with the audit requirements of the tax authority.
