2026 Customs Crackdown on Transit Trade: A Must-Read Compliance Guide for Foreign Trade Enterprises

2026 Transit Trade Crackdown: Compliance Risks Foreign Trade Enterprises Cannot Ignore

In March 2026,a batch of precision instruments transiting to the EU at Shanghai Waigaoqiao Port Area was subject to targeted customs inspection.The enterprise failed to retain third-party warehousing documents,which led to obstacles in Certificate of Origin verification and ultimately resulted in demurrage charges of RMB 180,000.This is not an isolated case: since 2026,the targeting rate of transit trade at ports such as Shanghai and Ningbo has increased by 42% year-on-year,and customs authorities of major trading partners including Europe,the US,and ASEAN have also tightened compliance reviews of transit goods simultaneously.

Core Changes in Global Transit Trade Supervision

The 2026 crackdown is not a temporary measure but a normalized upgrade of the global trade compliance system: the EU has revised the Implementing Regulations of the Rules of Origin,requiring transit goods to provide full transportation track records; U.S.Customs has stepped up inspections of China’s transit trade to avoid anti-dumping duties,increasing the inspection rate from 15% to 38%; RCEP member states have used the electronic networked system for Certificates of Origin to complete cross-border document verification within 10 minutes.

As the core port for transit trade in China,the General Administration of Customs has explicitly listed transit trade as an annual supervision priority in 2026.Leveraging the Shanghai International Trade Single Window,it has achieved full-chain data tracing for transit goods,and any document omissions by enterprises may trigger targeted inspections.

5 Non-Negotiable Compliance Red Lines for Transit Trade

• Certificate of Origin Fraud or Non-Compliance: For example,labeling goods produced in non-RCEP member states as originating from ASEAN,or forging third-party inspection reports.This is the top trigger for customs targeted inspections in 2026.
• HS Code Classification Errors: For example,classifying ordinary fasteners under high-tariff special hardware codes,leading to discrepancies between declared value and actual value and triggering valuation risks.
• Inconsistent Transportation Trajectory: Failure to declare container rehandling or transshipment to customs during the transit process,leading to inconsistencies between the goods trajectory and documents.
• Inconsistent Payment Route with Trading Entity: Failure to provide a power of attorney for third-party payments,which is identified as abnormal foreign exchange flow.
• Failure to Declare Transit Attributes Truthfully: Declaring transit goods as general exports without submitting a transit trade registration form.

Practical Case: Full Process Compliance Rectification of Transit Trade for a Hardware Enterprise

Situation: In May 2026,carbon steel fasteners from a hardware factory in Ningbo,Zhejiang,transiting to the US were targeted by Shanghai Customs due to HS Code classification errors,facing a 20% risk of back-payment of anti-dumping duties.

Task: Assist the enterprise in completing customs inspection,avoiding anti-dumping duties,and achieving quick customs clearance.

Action: Our team first retrieved production records and material inspection reports for the batch,adjusting the HS Code from 73181500 (high tariff) to 73181900 (ordinary fasteners,no anti-dumping duties).Meanwhile,we contacted Ningbo Customs to issue a revised Certificate of Origin and supplemented full transportation track documents.Finally,we coordinated with the Shanghai Customs Document Review Center to complete pre-classification review in advance.

Result: The inspection was completed in just 3 working days,the goods were cleared smoothly,and the enterprise avoided RMB 1.2 million in back-payment of anti-dumping duties and demurrage losses.

3 Key Actions for Enterprise Self-Inspection

• Quarterly verify whether the manufacturer,material,and specifications of the product match those on the Certificate of Origin.
• Entrust a professional organization for HS Code pre-classification to avoid declaration errors.
• Retain full transportation,payment,and warehousing documents for at least 5 years for customs inspection.

The 2026 transit trade crackdown is essentially a test of enterprises’ full-chain compliance capabilities.Many enterprises consider transit trade as a “gray area”,but in reality,under the global compliance system,any violation will lead to heavy costs.As a professional foreign trade agency based in Shanghai,we rely on the national port linkage network and global compliance resources to provide enterprises with full-chain services from document review to overseas customs clearance,helping enterprises avoid compliance pitfalls in transit trade.
