I'm a newcomer to the imported aquatic products business in Shanwei. Last month, I used a small customs broker for my first shipment. They omitted several declaration elements, which resulted in my goods being held at the port for 3 days.
I not only incurred over eight thousand yuan in demurrage fees but also missed the delivery deadline to my client and had to pay a penalty. Now I'm preparing to ship another batch, and I'm very anxious, afraid of encountering problems again. I want to ask, what exactly are the required declaration elements for agent import customs declaration in Shanwei in 2026?
Which ones are mandatory and must not be omitted? Will there be additional requirements for declaration elements for different categories of imported goods? Could you please explain clearly to help me avoid making costly mistakes again?

A common industry misconception is that declaration elements only require filling in three basic pieces of information: product name，composition，and value，and the rest can be filled in arbitrarily or left blank. Many small agents also default to simplified declarations to speed up document processing.
The chain reaction of such operations is very direct: Shanwei port has fully implemented an intelligent document review system in 2026. Missing items or incorrect entries will directly trigger manual review and control measures. At best，this causes a 1-3 day clearance delay，incurring demurrage and container detention fees. At worst，it leads to direct cargo detention and declaration amendment，affecting the letter of credit delivery period，and may even trigger customs audits leaving a negative record.
The basic mandatory declaration elements for regular imported goods include: product name，intended use，composition and content，specifications and model，country of origin，terms of trade，unit price and total price，certificate of origin number，and brand type. For goods subject to statutory inspection and quarantine，the Quarantine Approval Number must be additionally filled in.
For special categories，such as imported food requiring production date and batch number，or imported chemicals requiring CAS number，it is important to note that these additional elements for special categories are mandatory requirements and cannot be omitted.
The risk isolation method is: when entrusting an agent for customs declaration，request the agent to provide a checklist of declaration elements for the corresponding product category in advance. Verify all elements one day before shipment，confirm there are no omissions，and then submit the declaration. Simultaneously，require the agent to utilize an intelligent pre-screening system to check for errors and omissions beforehand，preventing the risk of missing or incorrect entries at the source.

In addition to basic universal elements, declaration elements related to customs valuation cannot be ignored. This includes adjustment items for the transaction price, such as whether it includes overseas freight, insurance, royalty fees, and details on commission rebates or discount amounts. These must be truthfully declared.
The Shanwei port currently implements nationwide customs integration valuation rules. Concealing or omitting valuation-related elements will directly trigger a valuation adjustment, requiring supplementary provision of payment vouchers, contracts, invoices, and other materials, and may also result in tax late payment penalties.
For imported goods involving cross-border related-party transactions, it is additionally necessary to declare the related-party transaction situation and provide proof of price composition to ensure the valuation process proceeds smoothly. If previous issues with declaration elements have caused valuation anomalies, it is necessary to promptly organize complete price documentation, cooperate with customs verification, and complete the clearance process as soon as possible to minimize losses.

Declaration elements related to foreign exchange receipts and payments need to match foreign exchange regulatory requirements. These include transaction currency, payment method, and trading country information. These elements are not only used for customs declaration but are also synchronized to the foreign exchange regulatory system.
Incorrect entries can affect the normal processing of subsequent foreign exchange settlement and purchase. In 2026, with the increased proportion of RMB cross-border settlement, the Shanwei port requires clear labeling of the settlement currency as RMB for imported goods settled in RMB, along with filling in the CIPS declaration number, to avoid affecting subsequent verification.
For special trade methods, such as returned goods or leasing trade, it is necessary to additionally declare the corresponding trade method code and the original customs declaration number, ensuring a complete compliance chain and avoiding issues with foreign exchange receipt/payment suspension. All declaration elements involving funds must be consistent with the contract and payment vouchers; mismatches are not allowed.

The content filled in for declaration elements must match the actual goods, as this directly affects the results of on-site inspection. For example, if the declared composition, content, specifications, model, or country of origin does not match the inspection results after the actual goods are unpacked, it will be directly deemed an inaccurate declaration, leading to penalties.
During the inspection process at Shanwei port, the intelligent document review system directly compares declaration elements with scanned images and commodity information data. Any discrepancies will trigger a container unpacking inspection, causing significant delays.
For imported goods bearing a brand, it is necessary to clearly declare whether the brand type is a self-owned brand or a foreign brand, and whether authorization has been obtained, to avoid cargo detention due to intellectual property issues. After completing the declaration elements, you can verify the goods and document information in advance to ensure consistency with the actual goods, reducing the probability of inspection anomalies.

Declaration elements related to taxation need to be accurately filled in. This includes whether the country of origin enjoys a preferential agreement tariff rate. The corresponding required origin elements, including the certificate of origin number and port of shipment information, must be completely filled in to successfully enjoy the preferential tariff rate and reduce import duties.
If applying for VAT deferral, it is necessary to clearly declare the deferral declaration identifier. Incorrect entries will result in the inability to process the deferral, requiring prepayment of VAT and tying up working capital.
For imported consumer goods, it is necessary to clearly declare the relevant elements corresponding to the excise tax tariff code, confirm whether they fall within the scope of excise tax, and avoid penalties for underpayment of taxes. Different tariff codes have different requirements for declaration elements. It is necessary to accurately fill in the corresponding tax-related elements based on the classification result to ensure the tax process is compliant.

The content filled in for declaration elements will serve as legal evidence in subsequent trade disputes. For example, declared information on origin, brand, and specifications/model can affect the process of letter of credit negotiation and transfer of title. If declaration elements are incorrectly filled, leading to document discrepancies, it can trigger letter of credit refusal, affecting payment collection.
For imported goods involving intellectual property, it is necessary to clearly declare whether authorization has been obtained and whether it complies with customs intellectual property filing requirements, to avoid cargo detention and legal disputes due to inaccurate declaration. Under special trade methods, such as consignment or exhibition sales, it is necessary to clearly declare the corresponding trade elements to ensure clear ownership of the goods and avoid subsequent title disputes. All declaration elements must be consistent with the terms of the trade contract to avoid contradictions that could lead to disputes.

For dangerous goods or goods under special supervision, packaging-related declaration elements are mandatory. These include packaging method, UN packaging number, dangerous goods classification, and component information corresponding to the MSDS.
Incorrect or omitted entries for these elements will directly result in the goods being unable to clear customs. The Shanwei port has very strict audits for declaration elements of imported dangerous goods, requiring accurate declaration of packaging category, packaging specifications, hazard classification information, consistent with the provided MSDS and dangerous goods classification identification report.
For ordinary goods, special packaging such as moisture-proof or damage-proof also needs to be clearly indicated in the declaration elements to avoid liability disputes arising from goods damage during transportation. When declaring packaging-related elements, they must match the actual packaging situation; false reporting or concealment is not allowed, as it may trigger safety risk warnings and lead to cargo detention for correction.

The accurate filling of declaration elements affects the turnover efficiency of the entire supply chain. Errors and omissions can lead to clearance delays, disrupting inventory and distribution plans, and increasing overall supply chain costs.
For imported goods under different Incoterms, the requirements for filling in declaration elements such as terms of trade, freight, and insurance differ. There are clear distinctions between the elements required for FOB and CIF terms. Incorrect entries can lead to errors in calculating the dutiable value, resulting in tax discrepancies.
For goods imported in multiple batches, it is necessary to clearly declare batch information, corresponding to specific orders and inventory plans, to facilitate subsequent supply chain management. Sorting out all required declaration elements in advance and preparing all information ahead of time can shorten customs review time, expedite cargo release, improve the turnover efficiency of the entire supply chain, and reduce overall operating costs.
