Core Pain Points of Dangerous Goods Customs Declaration in 2026: Starting from Manager Sun’s Experience

At the end of 2025,Manager Sun from a chemical enterprise in Shanghai encountered trouble: a batch of flammable liquids exported to Southeast Asia was detained by customs for 7 days due to classification error during declaration (Class 3 flammable liquids were incorrectly declared as Class 4).This not only delayed delivery,but also incurred more than 20,000 yuan in storage fees and penalties,with direct losses exceeding 100,000 yuan."The customs clearance company we hired at that time did not even understand GHS classification standards,let alone the new regulations to take effect in 2026," Manager Sun later recalled.

In 2026,global trade volume of dangerous goods increased by 12% year on year,while customs compliance requirements for dangerous goods declaration have been further tightened -- UN GHS Revision 10 has been officially implemented,and domestic customs have updated hazardous chemical declaration rules accordingly.According to industry survey data,the number of goods inspected due to non-compliant dangerous goods declaration at Shanghai Port in the first three months of this year rose 18% year on year.This means that choosing the right dangerous goods customs clearance company has become one of the core demands of foreign trade enterprises.

Three Core Pain Points of Dangerous Goods Customs Declaration in 2026

Pain Point 1: Compliance Risks Caused by Classification Errors

Dangerous goods classification is the core prerequisite for customs declaration,but GHS Revision 10 adjusted classification standards for some substances in 2026 (such as flammability grading for some new coatings).Many small customs clearance companies fail to update their knowledge base in time,leading to classification errors.Manager Sun’s case is typical: classification under the old standard became invalid in 2026,and the customs clearance company did not carry out the latest identification.

Pain Point 2: Delays Caused by Poor Process Connection

Dangerous goods customs declaration involves multiple links including customs declaration and inspection,international transportation and hazardous chemical storage.Poor connection of any link may cause delays.For example,some customs clearance companies only take charge of declaration and do not understand qualification requirements for hazardous chemical warehouses,leading to no compliant storage available after goods arrive at the port,and delays of 3 to 5 days are common.

Pain Point 3: Fast Update of New Regulations Makes It Difficult for Enterprises to Follow Up

In addition to GHS Revision 10,China also issued the 2026 Edition of Rules for Import and Export Declaration of Hazardous Chemicals in 2026,which puts forward higher requirements for completeness of declaration information (such as requiring supplementary description of protective measures during transportation).Many enterprises face high costs to follow up new regulations on their own,while small customs clearance companies often update their service contents 3 to 6 months later.
