2026 General Import Customs Clearance Full Process Guidelines

General import customs clearance is a necessary process for all regular trade cargo entering the country.The new-generation intelligent valuation and targeting system launched by customs in 2026 has increased the consistency and compliance requirements for declaration data by over 30%.Once problems such as document inconsistency,classification deviation,and abnormal cargo value occur,inspections,delays,additional taxes,or even return shipment risks will be triggered directly.Shanghai,as the nation’s largest import port,has leading customs rules transparency and operation efficiency across the country,and relevant standards have become a reference benchmark for ports nationwide.

Core Requirements Comparison of General Import Customs Clearance for Different Cargo Categories in 2026

Control of Core Operation Nodes in General Import Customs Clearance

HS code classification is the core foundation of the entire customs clearance process.In 2026,the customs classification database has covered parameter information of 1.2 million common imported goods worldwide.A classification deviation of more than two tariff items will directly trigger manual document review,and even be judged as inaccurate declaration,facing a penalty of 5%-30% of the cargo value.When enterprises declare independently,they often only pay attention to the matching of commodity names,while ignoring core classification parameters such as material,function,and usage scenario,which is the primary cause of customs clearance delays.

The consistency check of declaration elements needs to be advanced to the goods preparation stage.In 2026,Shanghai Port has realized automatic tripartite comparison of manifest data,declaration data,and inspection data.Even a character deviation in declaration elements such as brand,model,material,and specification will trigger intelligent targeting.For different trade terms such as FOB and EXW,it is necessary to sort out payment vouchers for overseas freight,insurance premiums,and other charges in advance to avoid declaration value calculation deviations.

Customs valuation anticipation can greatly reduce clearance time.In 2026,the customs valuation big data system has synchronized transaction data from 180 countries and regions worldwide.A declared value deviating from the average import price of the same category in the same period by ±10% will be automatically marked.Enterprises need to prepare materials such as foreign exchange payment vouchers,certificate of origin,and manufacturer’s price instructions in advance.Once subjected to valuation,they can submit supporting documents immediately to avoid entering the price consultation process and delaying time.

Practical Tips to Avoid Pitfalls in General Import Customs Clearance

• Submit full documents for pre-audit 7 working days in advance,focusing on checking the value logic consistency of certificate of origin,trade contract,and foreign exchange payment vouchers,to avoid being subjected to valuation due to declared value deviating from the customs big data interval.Once entering the price consultation process,it will delay at least 5-7 working days.
• For goods imported under EXW terms,separately organize and file vouchers for overseas freight,insurance premiums,and handling fees in advance.In 2026,customs valuation has included all overseas charges in the declared value calculation scope.Failure to report in advance will directly increase the tax base and cause unnecessary tax costs.
• Goods in the legal inspection list should be pre-inspected overseas in advance.Wooden packaging must bear the IPPC mark; otherwise,it will be detained for fumigation after arrival at the port,resulting in at least 3 days of demurrage and fumigation and storage costs ranging from CNY 2,000 to 5,000.

Common Risks and Avoidance Solutions in General Import Customs Clearance

Bill of lading exchange fee traps are the most easily overlooked hidden costs.Many overseas-designated freight forwarders split the bill of lading exchange fee into multiple items such as exchange fee,document fee,handling fee,and equipment handover fee.The actual market standard for general cargo FCL bill of lading exchange fee at Shanghai Port is CNY 200-300 per shipment,and LCL exchange fee does not exceed CNY 50 per cubic meter.Any excess is unreasonable charges.You can entrust an agent to verify the fee details with the freight forwarder in advance to avoid being overcharged.

Demurrage risk requires advance planning.Imported goods at Shanghai Port have 4 days of free storage period after arrival at the port.After the deadline,daily storage and container demurrage fees can reach 0.1%-0.3% of the cargo value.If it involves inspection and quarantine,valuation,or other processes,the free storage period will not be extended.Enterprises can apply for pre-inspection and pre-valuation in advance to advance the customs clearance process before the goods arrive at the port,ensuring release within 2 days after arrival.

Anti-dumping duty warnings require advance screening.In 2026,China imposed anti-dumping duties on over 200 kinds of goods from Europe,the United States,Southeast Asia,and other regions.Many importers failed to check qualifications before shipment and found that they needed to pay additional anti-dumping duties up to 200% after arrival,eventually having to choose return shipment or abandonment of goods.For goods imported from RCEP member states,you can verify the compliance of the certificate of origin in advance to enjoy zero-tariff preferences,reducing import costs by up to 15%.

In March 2026,Mr.Qin from Suzhou imported a batch of industrial valves from Germany.During independent declaration,he was judged to involve anti-dumping duties due to HS code classification deviation,needing to pay additional taxes of 27%.Meanwhile,the goods were placed under targeted inspection.If not released within 5 days,it would cause production line shutdown losses.After receiving the request,the Zhongshitong team immediately retrieved technical parameters such as valve material,pressure grade,and usage scenario,reclassified it to the correct HS code,and submitted the certificate of origin,technical specifications,and same-category import declaration records to the customs valuation department for communication.The amendment review was completed in 2 working days,reducing the additional taxes from the original CNY 320,000 to CNY 48,000,and the goods were released within 3 days without additional demurrage fees.
