In short
- Ordinary export cartons will not do. Dangerous goods packaging must conform to a UN specification matched to the class, packing group and package type.
- Two documents support it: the performance certificate from the packaging maker, and the use certificate for the packed consignment. Carriers read both.
- Marking then has to match: UN specification mark on the package, hazard labels for the class, and the correct shipping name alongside the UN number.
The three documents behind every package
| Document | Issued by | What it proves |
|---|---|---|
| UN specification mark | Applied by the packaging maker | The packaging design passed the applicable performance tests |
| Performance certificate | Packaging maker or testing body | The design, material and closure method tested and passed |
| Use certificate | Testing body, for the packed goods | This consignment is correctly packed, marked and labelled |
Why specification packaging is not interchangeable
- The code on the package means something. It encodes the package type, the packing group it is approved for and the test level achieved.
- A stronger-looking box may still be non-compliant if it lacks the mark or was approved for a different packing group.
- Closure method counts. The certificate covers a specific closing procedure; deviating from it invalidates the approval.
- Inner packaging matters too. The combination of inner and outer packaging is what was tested.
Check the mark Look for the UN specification mark on the outer packaging before loading. A plain carton with the right label stuck on is a defect, not a shortcut.
Marking and labelling: what goes where
- UN specification mark on the outer packaging, legible and intact.
- Hazard labels for the class, plus subsidiary risk labels where applicable.
- Proper shipping name and UN number marked as required, matching the declaration and the bill.
- Marine pollutant mark where the classification calls for it.
- Overpack markings if individual packages are consolidated into a larger unit.
Where consignments fail inspection
- The package carries a mark approved for a different packing group from the one on the test report.
- The closure procedure differs from the certified method — tape instead of the specified closure, for example.
- Labels are applied but the UN number is missing or does not match the declaration.
- Inner packaging was substituted for a cheaper equivalent without re-certification.
Cost of rework A packaging defect found at the loading port means unpacking, re-packing and possibly re-testing — with the container on the clock.
Practical sequence
- Confirm the classification first: class, UN number and packing group.
- Source packaging approved for that combination, and keep the performance certificate on file.
- Follow the certified closure and packing method exactly; photograph the packed unit before closing.
- Obtain the use certificate for the consignment from a testing body.
- Verify marks and labels against the documents, then release the cargo to the forwarder.
