Free hazmat compliance references.
PHMSA publishes the regulations. We publish the spreadsheets. Drivers, dispatchers, fleet safety leads, and compliance officers — everything we've made available, in one place. Free, CC BY 4.0, refreshed when PHMSA amends.
DOT Hazmat Table
The full Hazardous Materials Table, byte-verified against the eCFR HTML across all 14 columns: Symbols, PSN, Hazard Class, ID Number, PG, Label Codes, Special Provisions, Packaging, Quantity Limits, Vessel Stowage.
2024 ERG UN→Guide Lookup
The yellow-pages UN/NA → guide-number index from the official 2024 ERG, plus guide reference for every populated guide. Includes a Quick Lookup tab — type a UN number, get the guide instantly.
Segregation Matrix
The full hazardous-materials segregation matrix — which hazard classes you can and can't load together, with the conditional cells and exceptions. Transcribed cell-by-cell from the CFR PDF.
Appendix A · Hazardous Substances
The list of hazardous substances with their CERCLA Reportable Quantities (RQs). What triggers EPA notification on a release, paired with the DOT-side classification data so you can answer both questions from one file.
How these are verified
Every entry in every file traces to its authoritative published source (eCFR HTML for 49 CFR data, the official PHMSA-published PDF for the 2024 ERG). Each file's About sheet records the source URL, snapshot date, and SHA-256 of the parsed data so anyone can audit the verification chain end-to-end. Our open ingest pipeline lives at github.com/zackaryfoster28-tech/haulguard-ai — every script that produced the published files is in the repo.
Need more than reference data?
HaulGuard scans the Bill of Lading, generates the placards under § 172.504, checks segregation under § 177.848, and produces a tamper-evident audit trail your driver can present at inspection. The files above are inputs. The product is the engine.
