How to Choose a Nantong Import Customs Broker? Full-Category Operation Guide for General Cargo/Dangerous Goods/Equipment

Core Service Capabilities of Nantong Import Customs Brokers

In 2026,as a river-sea transportation hub in the Yangtze River Delta,Nantong’s total import volume rose 27% year-on-year,with imports of mechanical and electrical equipment,chemical raw materials,and fresh agricultural products all growing by over 40%.Many local manufacturing and trading enterprises in Nantong often encounter issues like incomplete documents,incorrect classification,and valuation disputes when handling import business for the first time.Last year,I assisted Mr.Jiang from Chongchuan District,Nantong,with the import of a used injection molding machine.The small local agency he initially hired was unfamiliar with regulatory rules for used mechanical and electrical products,leading to an incorrect HS code classification that resulted in an overpayment of 120,000 yuan in customs duties and 8 days of demurrage fees.Later,we reorganized the classification logic and used the channel linking Shanghai Port with Nantong’s local inspection process,completing clearance and cargo release in 3 days and helping him apply for a refund of the overpaid duties.

Many enterprises default to choosing locally registered agencies when seeking Nantong import customs brokers.In reality,the Yangtze River Delta Port Integrated Declaration system was fully implemented in 2026.Agents with cross-regional qualifications can directly connect to the systems of core ports such as Shanghai,Ningbo,and Taicang without needing to transfer documents a second time,resulting in higher efficiency and lower costs.Especially for businesses involving pre-shipment inspection (PSI),import licenses,and RCEP tariff reductions,agents from core ports have far better rule familiarity and coordination capabilities than small local agencies.

Key Tips to Avoid Pitfalls When Choosing a Nantong Import Customs Broker

• Verify the agent’s cross-port declaration qualification in advance.In 2026,most small and medium-sized local agencies in Nantong only have the authority to declare general cargo locally.When handling special categories involving 3C certification,pre-shipment inspection,or import licenses that require operation at core ports like Shanghai and Ningbo,they often lack filing qualifications and must outsource the work,leading to a cost increase of over 30% and unclear responsibility division.Prioritize agencies with filing records at all Yangtze River Delta ports.
• Clarify pricing rules for all fee items and include them in the service contract in advance.Many agents attract customers with quotes far below market prices,then charge separately for document exchange fees,late declaration fees,container opening fees for inspection,and urgent coordination fees—resulting in total costs more than double the initial quote.Before signing,require the agent to provide a full-process fee list and clarify the responsible party for abnormal fees.
• Confirm responsibility for HS code classification.In 2026,customs’ retrospective period for classification errors has been extended to 5 years.If a classification error leads to underpayment of duties,the consignor will bear the consequences of subsequent tax replenishment,late payment penalties,and credit sanctions.Choose an agent that can issue a formal classification opinion and clarify compensation responsibility for classification errors; do not trust verbal promises of "low-tax classification."

Compliance Risk Warning for Nantong Import Customs Clearance

In 2026,the verification rate of Certificates of Origin under RCEP has been increased to 18%.For goods imported from RCEP member states such as ASEAN,Japan,and South Korea that are declared for tariff reduction,verify the authenticity of the Certificate of Origin and whether the goods meet origin standards for tariff relief in advance.Otherwise,you will not only have to repay full duties but also be added to the customs dishonesty list,resulting in higher inspection rates for all future import and export goods.For goods imported under EXW terms,confirm the completeness of foreign-section logistics and export declaration documents in advance; otherwise,document exchange cannot be completed normally upon arrival,with daily demurrage fees reaching up to thousands of yuan.If goods are detained for over 14 days,they will be returned by customs.

In addition,in 2026,the accuracy of customs’ big data comparison for import valuation has been greatly improved.Do not underdeclare goods value to reduce duty payments.Once flagged by the valuation system,you will need to provide full transaction vouchers and foreign exchange records to prove value authenticity,leading to port detention of goods.In serious cases,the matter will be transferred to anti-smuggling authorities for investigation.Professional agents will provide reasonable declaration suggestions in advance based on past prices of similar goods and prepare supporting materials to avoid valuation disputes.
