Dangerous Goods
Goods with explosive/flammable/corrosive/toxic hazards, regulated by UN class and number, requiring formal declaration, proper packaging and qualified channels.
Dangerous Goods (DG; also Hazmat) are goods that may endanger people, property or the environment during transport and are mandatorily regulated by international rules. Air transport follows IATA's Dangerous Goods Regulations (DGR) and sea transport follows the IMDG Code, classifying substances into 9 hazard classes (e.g. Class 1 explosives, Class 3 flammable liquids, Class 8 corrosives, Class 9 miscellaneous incl. lithium batteries), each with a corresponding UN Number and packing group.
- 合规要件：危险品需经鉴定分类，提供 MSDS/SDS、危险品包装使用鉴定结果单与（空运）鉴定报告，使用合规 UN 包装、危险品标记标签，并由具资质人员/渠道按规则申报承运。
- 责任/费用边界：分类、包装、申报与文件责任在托运人（发货方）；危险品运输价格、附加费与可接收性远高于普货，且受航司/船司逐票审核。
- 常见坑：把危险品「降级」为普货或敏感货瞒报承运，是航空/海运安全的重大违规，可能导致扣货、巨额罚款、列入黑名单甚至刑事责任；化工、电池、香水、含酒精/压力气体的产品尤需先做属性鉴定。
FAQ
- How do I know whether my goods are dangerous goods?
- Rely on the product's MSDS/SDS and a professional DG classification, not intuition. Products with lithium batteries, flammable liquids, pressurized gases, corrosives, alcohol content or strong magnetism may fall into one of the 9 classes. Obtain a hazard classification before shipping to confirm the UN number, class and packing group.
- Are DG requirements the same for air and sea?
- No. Air follows IATA DGR with stricter limits and requires an air-transport assessment; sea follows the IMDG Code. The same substance may have different acceptability, packaging and declaration requirements between modes, so handle each under its own rules and use a forwarder/route qualified for DG.
