International Dangerous Goods Transportation Guide:
Navigating the complex landscape of dangerous goods logistics requires precision and expertise—one misstep in documentation or packaging can lead to delays, fines, or catastrophic safety risks. Partnering with an experienced China freight forwarder is critical for navigating these challenges successfully.
Why Dangerous Goods Compliance Matters in International Freight
International transportation of dangerous goods (DG) is governed by stringent regulations to ensure safety across global supply chains. Non-compliance can result in average fines of $30,000–$50,000 per incident (IATA, 2025) and severe operational disruptions.
This guide provides a structured approach to DG logistics, covering certifications, packaging, and end-to-end compliance processes for global buyers working with a freight forwarder specializing in international freight from China.
Classification and Identification:
a. UN Number and Proper Shipping Name (PSN)
• Every dangerous good must be assigned a 4-digit UN number (e.g., UN3480 for lithium-ion batteries) and a PSN aligned with the UN Model Regulations. A knowledgeable China freight forwarder can help accurately classify your goods to avoid costly errors in international freight shipments.
b. Hazard Classes
• The 9 hazard classes define primary risks. An experienced freight forwarder will verify your products fall under the correct classification:
1.Explosives (e.g., UN0336 for fireworks)
2.Gases (e.g., UN1072 for oxygen compressed)
c. Critical Documentation
• Safety Data Sheet (SDS/MSDS): Must include 16 sections compliant with GHS Rev. 10 (2025). Your China freight forwarder should review this documentation to ensure compliance with international freight regulations.
Packaging Standards: Beyond Basic Containment
a. UN-Certified Packaging
• Packaging must pass rigorous tests per UN ISO 16106:2025. A reliable freight forwarder in China will ensure all packaging meets these international standards for international freight shipments.
b. Marking and Labeling
• Primary Hazard Labels: Diamond-shaped labels with class number. Your China freight forwarder should verify all markings meet international freight requirements
c.Specialized Packaging by Hazard Class
Hazard Class
Class 3 (Flammable Liquids)
Class 8 (Corrosives)
Packaging Requirement
UN-certified metal drums with leak-proof seals
Anti-corrosion materials
Modal Regulations: Air, Sea, and Land Compliance
a. Air Freight (IATA DGR)
Key Restrictions:
• Lithium batteries >35 kg prohibited on passenger aircraft. Your freight forwarder should advise on these limitations for international freight via air.
（Cargo planes can break through this limit）
b. Sea Freight (IMDG Code)
Container Requirements:
• Ventilated containers for flammable gases. Your China freight forwarder can arrange appropriate containers for international freight shipments.
（Different special dangerous goods require special containers for loading）
c. Road/Rail (ADR/RID 2025)
Vehicle Specifications:
• Specialized vehicles required. A qualified freight forwarder will ensure proper equipment for international freight transportation.

“Dangerous goods logistics isn’t about avoiding risks—it’s about managing them with precision. Compliance is the price of entry for global trade, and the right freight forwarder makes all the difference in international freight operations.” — Global Logistics Safety Council, 2025
Transporting dangerous goods requires extreme caution. Avoid working with freight forwarders who conceal or underdeclare hazardous materials, as such practices can lead to severe consequences. In 2025, several incidents involving concealed or misdeclared dangerous goods occurred at Shekou Port and Yantian Port in Shenzhen, China, resulting in multiple container fires.
Partnering with compliant and professional freight forwarders ensures more stable, safe, and sustainable trade operations.
