How to Choose Gaoyou Imported Aluminum Agent: Avoid 8 Common Risks Such as Customs Valuation, Supplementary Tax and Anti-Dumping Duty

In October 2025,Mr.Zhu,who operates a new energy battery structural component business in Gaoyou,encountered an import problem: after 300 tons of 6061 aluminum coils he imported from South Korea arrived at the port,he was notified by customs that he needed to pay a supplementary anti-dumping duty of 278,000 yuan.Meanwhile,his commodity inspection application was rejected due to parameter discrepancies between the MTC quality certificate and declared elements,resulting in 8 days of port detention and 72,000 yuan of demurrage.When he contacted us for handling,he said the local freight forwarder had never mentioned anti-dumping duty or document pre-audit before,leading to hundreds of thousands of yuan in unnecessary extra costs.

Core Compliance Thresholds for Aluminum Import in Gaoyou and 2026 Regulatory Requirements

In 2026,the General Administration of Customs updated the supervision rules for imported aluminum,implementing differentiated tariff policies for aluminum products from different countries of origin,and increasing the verification intensity for certificates of origin and quality certificates by 30%.Enterprises should clarify corresponding supervision requirements before import to avoid risks.

Common Pitfalls for Gaoyou Enterprises Importing Aluminum and Avoidance Guide

We have handled more than 200 aluminum import orders for Gaoyou clients,and summarized the most common pitfalls for enterprises as follows:

• Customs valuation deviation and supplementary tax payment: In 2026,customs updated the aluminum import valuation benchmark to the average global transaction price of the past 6 months.If the declared price is more than 10% lower than the benchmark price,it will directly trigger manual valuation.Enterprises should prepare original factory invoices and foreign exchange payment vouchers in advance to prove the authenticity of the transaction and avoid supplementary tax payment.
• Document discrepancy and port detention: Many enterprises submit MTC quality certificates with parameters inconsistent with declared elements,or RCEP certificates of origin with incorrect marking of cumulative rules of origin,leading to direct rejection by commodity inspection.Demurrage is calculated at 1,200 yuan per day per container.Conducting document pre-audit 3 days in advance can 100% avoid this risk.
• Unpaid anti-dumping duty: Some enterprises import aluminum from entrepot countries without verifying whether the actual country of origin is on the anti-dumping list.After verification by customs,they need to pay supplementary anti-dumping duty of 15%-40%,and will be included in the high-risk enterprise list,resulting in inspection for every subsequent import.
• Weight measurement error loss: Bulk aluminum import usually adopts draft survey for weight measurement.If the draft measurement deviation at loading and discharging ports exceeds 0.3%,the enterprise will bear the weight loss directly.Enterprises can arrange third-party inspection institutions to supervise loading and unloading on site,controlling the deviation within 0.1%.

Practical Advantages of Shanghai Port Linked Service for Gaoyou Enterprises

Our headquarters is located in Shanghai,with cross-port declaration qualification for all ports nationwide.Gaoyou enterprises do not need to go to the port for on-site docking,and all processes can be completed online.We have long-term cooperation with fleets for the land transport line from Shanghai Port to Gaoyou,with 20-hour direct delivery,which is 30% faster than ordinary freight forwarders,and the transport cost is about 15% lower.

At the same time,we have set up agency outlets in 32 major aluminum exporting countries around the world,and can provide services under all trade terms including EXW,FOB,CIF,including overseas door-to-door pickup,shipping space booking,and pre-verification of certificates of origin,to avoid document problems found only after goods arrive at the port,which may cause unnecessary losses.For bulk cargo import,we can coordinate with the port in advance to arrange berthing and priority loading and unloading,with a demurrage control rate of over 98%.

Full-process Agency Service Standard for Gaoyou Aluminum Import

We have customized a full-process agency service standard for the import needs of Gaoyou enterprises,with full chain control from contract signing to door-to-door delivery:

The first step is pre-tariff calculation.Based on the aluminum parameters and country of origin provided by the enterprise,we calculate all costs including tariff,anti-dumping duty,value-added tax in advance,and provide an accurate import budget to avoid overspending.The second step is document pre-audit.After the enterprise obtains all documents,we submit them to the system for pre-audit 3 days in advance,100% ensuring that the documents meet customs requirements and avoiding application rejection.The third step is customs declaration.We declare the goods 3 days before arrival at the port,and customs clearance can be completed within 1-2 days after arrival.The fourth step is door-to-door delivery.After customs clearance is completed,we directly arrange the special line fleet to deliver the goods to the factory in Gaoyou,without the need for the enterprise to pick up the goods by themselves.

For the aforementioned Mr.Zhu,after receiving his request,we immediately sorted out his original factory purchase contract,foreign exchange payment voucher,and certificate of origin issued by the supplier,submitted a customs valuation objection to the customs,and finally only paid a supplementary tax of 32,000 yuan.At the same time,we processed the urgent commodity inspection recheck,completed customs clearance within 2 days,arranged a special vehicle to deliver the goods to his factory,saving him a total cost of more than 300,000 yuan.He entrusted all his aluminum import business to us in 2026,and we have handled 12 containers in the first three months of this year,with an average customs clearance time of 1.8 days,without any compliance problems.

Finally,a risk warning: In the second half of 2026,customs will intensify the verification of the origin of aluminum imported via entrepot trade.Once it is found that the origin is falsely declared or the actual country of origin is concealed,in addition to paying all supplementary taxes and fees,a fine of 5%-30% of the cargo value will be imposed,and the enterprise will be included in the high-risk list,and all subsequent imported goods will be subject to key inspection.If enterprises are not familiar with import compliance requirements,they should not operate by themselves,and should find a professional agency to conduct full-process compliance audit in advance to avoid unnecessary losses.
