Packaging is the most important safety measure for dangerous goods, and the most common reason shipments are delayed or rejected. Regulations require packaging that has been tested and certified for the specific class and packing group. We advise you on the right packaging and help you obtain the inspection certificates needed to export from China.
Understanding UN packaging marks
Certified packaging carries a UN mark that shows its type, the packing groups it is approved for, its performance level and its manufacturer. For example, a marking that begins with UN 4G indicates a fibreboard box. Using packaging that is not approved for your product’s packing group is a violation, even when the package looks strong.
| Packing group | Danger level | Packaging performance |
|---|---|---|
| I | High danger | Highest standard (mark X) |
| II | Medium danger | Medium standard (marks X and Y) |
| III | Low danger | Standard (marks X, Y and Z) |
Packaging options
- Combination packagings: inner containers inside a UN outer box or drum, with cushioning or absorbent
- Drums and jerricans: steel, plastic or fibre, for liquids and solids
- IBCs: intermediate bulk containers for larger volumes of liquids
- Limited Quantity: small inner packagings with reduced requirements and the Limited Quantity mark
- Cylinders and pressure receptacles: for Class 2 gases
China Customs packaging inspection
Dangerous goods exported by sea from China normally need two documents from China Customs: the packaging performance inspection certificate (issued for the packaging manufacturer’s type) and the packaging use inspection certificate (issued for the goods packed in it). Certain goods are exempt, for example Limited Quantity shipments and some pressure receptacles that have their own certificates. We check whether your shipment is exempt and, if not, help you prepare the application.
Batteries
Lithium batteries also need the UN38.3 test summary in addition to correct packaging. See battery logistics.

FAQ
Can I reuse packaging for dangerous goods?
Only if it is undamaged, still approved for the product and packing group, and allowed for reuse by the regulations. We recommend new certified packaging for most exports.
What happens if the packaging is not compliant?
The cargo can be refused at the port or airport, rolled to a later sailing, or returned. Packaging problems are the most common cause of dangerous goods delays.
Regulations are revised regularly. IMDG Code Amendment 42-24 is mandatory from 1 January 2026 and the 67th Edition of the IATA Dangerous Goods Regulations applies during 2026. Requirements vary by carrier, port and destination, so please contact us to confirm the rules for your specific shipment.
