In short
- Dangerous goods bookings are reviewed by the carrier's dangerous goods desk, not by the ordinary booking team. That review has its own cut-off, its own documents list, and the right to say no.
- The practical consequences are simple: more lead time, a fixed document set, and a plan for the possibility that the cargo is refused or rolled.
- Approval does not carry over between sailings. Each booking is assessed on the cargo and the vessel, so a shipment that was accepted last month may be refused this month.
Why the separate chain exists
- Vessel constraints vary. Operators have limits on how much of each class may be carried, and where it may be stowed.
- Port and terminal rules differ. Some terminals accept certain classes only on certain days or under special arrangements.
- Transhipment is a second approval. If the service routes through a hub, the connecting carrier must also accept the cargo.
- Documentation is reviewed, not just received. An incomplete file stalls the booking rather than triggering a query.
The documents a DG booking normally needs
| Document | Purpose | Common defect |
|---|---|---|
| Classification or test report | Establishes class, UN number and packing group | Generic entries that cannot be mapped to a UN number |
| MSDS with section 14 | Corroborates the classification | Section 14 blank or for a different formulation |
| Booking declaration | Formal statement of the dangerous goods | Wording that differs from the report |
| Packing certificate or use certificate | Confirms the packaging was approved | Missing for classes that require it |
| Battery test summary (if applicable) | Covers the cell or battery design | Covers a different model from the one shipped |
Planning the lead time
- Start earlier than for general cargo. Add review time before the standard cut-off, not after.
- Book before production finishes where the schedule is tight, so the approval runs in parallel with manufacturing.
- Expect the answer to arrive late. DG desks handle volume; a booking submitted at the cut-off is a booking at risk.
- Have a fallback. If the carrier refuses, know whether another service, another sailing or a different packing arrangement is available.
Common trap Treating the shipping instruction as the deadline. The dangerous goods approval is the real gate, and it sits earlier in the timeline.
Reasons a booking gets refused
- The class or UN number claimed does not match the documents submitted.
- The vessel or the terminal cannot accept that class on that service.
- The packing does not conform to the specification for the packing group.
- The consignment quantity exceeds the carrier's limit for that class.
- The destination cannot handle the class, so the carrier declines to load it.
Plan B Refusal is not always final — it may be a matter of a different vessel, a different stowage position, or a different packing configuration. Ask what would make it acceptable.
Checklist before you book
- Classification conclusion in hand, with class, UN number and packing group.
- MSDS section 14 consistent with it.
- Packaging sourced or specified, with the performance certificate available.
- Use certificate arranged for classes that require it.
- Battery test summary covering the exact design, where relevant.
- Booking declaration drafted to match the documents word for word.
