How to Select a Qualified Nantong Import Customs Declaration Agency 2026 Practical Guide to Avoiding Common Pitfalls at Port Customs Clearance

Current Status and Common Pain Points of Nantong Import Customs Declaration Market

In 2026,the import cargo volume at Nantong Port increased by 27% year on year,with demand mainly concentrated in three categories: precision electromechanical equipment,chemical raw materials and daily consumer goods.80% of small and medium-sized importers will encounter compliance traps in their first operation.Many merchants prefer to choose small local agencies,whose actual service capabilities are uneven,which often leads to problems such as wrong HS code classification,poor communication during customs price audit,and delayed handling of abnormal issues.In mild cases,extra container detention fees and fines will be incurred; in severe cases,serious losses such as cargo detention at the port and goods return will happen.

Most small local customs declaration agencies in Nantong can only handle general cargo declaration at Nantong Port.When it comes to demands such as cross-port import,special categories (such as dangerous goods,electromechanical equipment) and RCEP tariff reduction,they generally need to subcontract the business to upstream agencies.Too many intermediate links lead to low efficiency,and compliance risks caused by information asymmetry easily occur.

Service Capability Comparison of Different Customs Declaration Agencies

Core Operation Key Points for Nantong Import Customs Declaration

• Pre-review HS Codes in advance.In 2026,China Customs updated classification rules for 217 product categories,covering electromechanical products,chemicals,food and other categories.Before declaration,classification must be completed in accordance with the latest tariff rules to avoid problems such as anti-dumping duty supplementary payment and cargo detention caused by wrong classification.For imported electromechanical equipment,it is also necessary to confirm in advance whether access documents such as China Inspection Certificate and Electromechanical Product Import License are required,to avoid the failure of customs clearance after cargo arrives at the port.
• Check the consistency of declaration elements.Information including brand,model,material,country of origin of the goods must be confirmed to fully match the declaration documents.In 2026,the penalty standard for inconsistent declaration at Nantong Port is 30% higher than that of last year,with the maximum fine up to 10% of the cargo value.For imported goods under RCEP,the filling specifications of the certificate of origin shall also be checked to ensure compliance with the latest 2026 tariff reduction requirements.
• Prepare price audit documents in advance.Full sets of documents including original manufacturer invoice,foreign exchange payment voucher,trade contract,freight insurance policy shall be prepared,which can be submitted directly when customs initiates price audit,to avoid overvalued tax collection and shorten customs clearance time.For niche commodities imported for the first time,enterprises can apply for advance ruling to the customs in advance to confirm the tax code and tax rate,so as to avoid subsequent disputes.

Common Risk Warning for Nantong Import Customs Declaration

The first risk is document exchange fee trap.Many small agencies hide additional fees such as document exchange fee and THC (Terminal Handling Charge) when quoting,and add extra charges temporarily during the customs clearance process,with an average extra charge of 1000-3000 RMB per shipment.Formal agencies will list all fee items at the quotation stage,and confirm with customers in advance before any extra fee is incurred,no temporary price increase will happen.

The second risk is container detention fee.In 2026,the free storage period for general cargo at Nantong Port is 3 days.After that,the daily charge per ton increases by 15%,and the detention fee for one week can reach 2% of the cargo value if the trailer arrangement for inspection is not made in advance.Professional agencies will predict the inspection probability in advance,make trailer arrangement plan in advance,and minimize the loss caused by container detention fee.

The third risk is certificate of origin compliance risk.For imported goods under RCEP,if the certificate of origin is not filled in accordance with the latest 2026 specifications,goods cannot enjoy 0-10% tariff reduction,and may even be judged as false declaration,facing a fine of 5%-30% of the cargo value.Professional agencies will verify all information of the certificate of origin at the document pre-review stage,to ensure compliance with tariff reduction requirements.
