HazmatTable Guide
Hazmat Shipping Checklist
A good shipping workflow moves from identification and classification into packaging, hazard communication and documentation.
Short answer
A good shipping workflow moves from identification and classification into packaging, hazard communication and documentation.
A good shipping workflow moves from identification and classification into packaging, hazard communication and documentation.
Why this matters
PHMSA emphasizes that classification drives the rest of the requirements, including packaging, markings, labels and shipping papers.
A better workflow
Work through the shipment in order: identify material → determine hazards → select proper shipping name → identify UN/NA number → confirm hazard class and packing group → check Appendix A/RQ → check special provisions → packaging → marking/labeling → shipping paper → emergency response information.
Check your material in HazmatTable
Search the table, compare the listed RQ, and see the source in seconds.
What HazmatTable helps with
- Search a chemical, synonym, waste code or radionuclide.
- See the listed RQ and units without scanning a long PDF.
- Preserve important Appendix A footnotes and source context.
- Compare an entered package quantity with the listed RQ.
- Continue into related shipping and classification guides.
Important: HazmatTable is a reference and workflow tool, not a legal certification of a shipment. The shipper must verify the current HMR and the actual material, quantity, packaging and mode.
