Guide to Precise Compliance Operation of Full-Process Import Agency Customs Clearance and Global Port Services

Analysis of Core Nodes in the Full Process of Import Agency Customs Clearance

In 2026,global trade rules continue to iterate,and the accuracy of customs supervision continues to improve.The customs clearance process for import enterprises is no longer a simple document submission,but involves multiple compliance nodes such as HS code classification,customs valuation,pre-inspection of commodity inspection,and license processing.Many customers reported that inconsistencies between declaration elements and actual goods alone lead to targeted inspection of goods,and even incur demurrage and tax supplementary costs.Among the hundreds of import cases we have handled,80% of the problems stem from inadequate preliminary document and compliance preparation.

Accurate HS Code Classification and Compliance Declaration

HS code is the core foundation of import customs clearance.In 2026,the General Administration of Customs updated the new version of HS code annotations,adding classification rules for more than 300 products.For example,codes for new energy energy storage equipment and intelligent security products have been adjusted.Incorrect classification will not only lead to deviations in tariff rates,but may also trigger anti-dumping duties or changes in regulatory conditions.

Last year,a customer from Suzhou imported residential energy storage inverters from Germany.The initially declared code was 85044099,while the actual corresponding code should be 85044011,as the former belongs to general transformers and the latter belongs to special photovoltaic inverters.We assisted the customer in submitting product technical parameter descriptions and original factory nameplate materials,cooperated with the customs to complete the classification reconsideration,and finally avoided a 20% tariff difference loss.It should be emphasized that: Declaration elements must be completely consistent with the actual goods,including details such as brand,model,material,and rated power.In 2026,the customs AI inspection deployment system can automatically compare declaration information with actual product pictures,and any slight deviation will trigger inspection.

Customs Valuation and Pre-Audit of Documents

In 2026,the customs valuation system is upgraded to a global big data comparison model,which automatically compares the transaction price of imported goods with the global transaction price of similar goods in the same period.Many customers have their customs valuation increased due to undervaluation of goods or failure to provide valid transaction vouchers,resulting in additional tariffs and value-added tax.

Our pre-audit process requires customers to provide complete transaction vouchers,including formal foreign trade contracts,commercial invoices,packing lists,ocean bills of lading,and foreign exchange payment slips.If there is third-party payment or commission,it must be listed separately.A Shanghai-based importer once had his customs valuation increased by 12% for failing to disclose the 5% commission paid to overseas suppliers,resulting in nearly 300,000 yuan of tax supplementary costs.In addition,hidden charges such as document exchange fees and yard fees are also common traps.We will confirm the fee details with the freight forwarder in advance to avoid additional expenses.

Commodity Inspection and Pre-Audit of Animal and Plant Quarantine

According to the category of imported products,commodity inspection and quarantine requirements vary greatly.For example,food and cosmetics require advance entry inspection and quarantine approval,while animal and plant products require application for entry animal and plant quarantine permit.In 2026,products imported from RCEP member countries can enjoy lower agreed tariff rates,but must submit qualified certificates of origin.

If importing Australian beef,the entry animal and plant quarantine permit must be applied for 15 working days in advance,otherwise the goods will be directly returned after arrival at the port.Our team will sort out the corresponding regulatory conditions of the products in advance,assist customers in preparing test reports required for quarantine and filing materials of manufacturing enterprises,and ensure that documents are complete before arranging shipment.

Import License Processing and Special Supervision

Some imported products require special licenses.For example,mechanical and electrical equipment require automatic import licenses,and hazardous chemicals require hazardous chemicals business licenses.In 2026,the online full-process approval for license processing of some mechanical and electrical products has been realized,but materials still need to be submitted 10 working days in advance.In addition,for some products from the United States,the European Union and other regions,attention should also be paid to the collection of anti-dumping duties and countervailing duties.For example,cold-rolled steel plates imported from the United States in 2026 are still subject to 25% anti-dumping duty.We will make tax planning for customers in advance and select appropriate procurement channels.

Common Risks in Import Customs Clearance and Avoidance Methods

• Incorrect HS code classification: Conduct pre-audit against the 2026 version of HS code annotations in advance,and contact the customs classification center to issue a pre-classification decision when necessary
• Incomplete documents: Sort out the list of core documents required for import,including contracts,invoices,packing lists,bills of lading,certificates of origin,etc.to avoid omission
• Customs valuation deviation: Provide authentic transaction vouchers.If there is a price dispute,you can submit a third-party price certificate or apply for price consultation
• Demurrage incurrence: Coordinate with shipping companies and yards in advance,reserve inspection time,optimize the logistics connection process,and avoid no one to declare after the goods arrive at the port
• Changes in regulatory conditions: Pay close attention to the latest 2026 customs policies in real time,adjust the import plan in advance,and avoid the failure of goods to clear customs due to policy changes
