Hazmat broker software that verifies endorsements on every inbound carrier reply.
Booking a carrier without verified hazmat authority isn't just a compliance risk — it's a liability event. Every carrier that replies to your hazmat load needs a hazmat endorsement, adequate insurance for hazardous cargo, and no route-restriction conflicts for the hazard class and lane combination. Checking that manually for 30+ inbound replies per load is how mistakes happen. Keelway runs the hazmat-specific carrier check automatically, flags carriers that fail before they hit the ranked list, and surfaces the compliant carriers in order of trust and rate.
Why hazmat carrier vetting can't be skipped
Most freight categories have a grace period for carrier vetting errors. Hazmat does not. Booking a carrier that lacks hazmat authority on an HM-regulated shipment creates personal liability for the broker, potential fines under DOT 49 CFR, and insurance exposure that standard cargo policies don't cover. The regulatory exposure alone makes automated hazmat endorsement checking a compliance requirement, not just an efficiency play.
The challenge is that hazmat loads generate the same volume of inbound carrier replies as any other load — often more, because hazmat rates attract opportunistic carriers who don't hold the required endorsements. Running a full hazmat authority check manually for every reply, on every load, across a coordinator team of even five people, is where compliance mistakes happen.
What Keelway checks on every hazmat carrier reply
On top of the standard carrier email triage layer — rate extraction, FMCSA operating authority, standard insurance — hazmat loads trigger an additional vetting stack:
- Hazmat cargo authority. The carrier's FMCSA operating authority record is checked specifically for hazmat-class permission. Standard freight authority without hazmat authority results in an immediate flag and a downrank — the carrier doesn't reach the ranked list until the coordinator reviews the flag.
- Insurance adequacy for hazardous materials. Hazmat cargo requires higher insurance minimums than standard freight under FMCSA regulations. Carriers whose insurance on file falls below the minimums for the hazard class in the load are flagged before appearing in the ranked list.
- Placard requirement acknowledgment. Keelway reads the UN number, hazard class, and packing group from the load record. When a carrier's reply doesn't address placard requirements — or when the carrier's equipment is inconsistent with the hazard class — that gap surfaces in the inquiry detail view.
- Route restriction conflicts. Certain hazard classes are prohibited from tunnels, bridges, and urban corridors under FMCSA 397. Keelway flags carriers whose stated routes include known restricted segments for the relevant hazard class in the load record.
- Fraud signals on above-market rates. Hazmat rates are structurally above market because of the compliance cost. That premium attracts chameleon carriers and identity fraud. Keelway runs the full MC-DOT mismatch, domain spoofing, and sudden lane-change detection described in our chameleon carrier guide.
The compliance gap in manual hazmat workflows
Most hazmat brokerages have a checklist. A coordinator opens the carrier reply, writes down the MC, opens FMCSA SAFER, checks authority, checks insurance, checks for hazmat endorsement, makes a note. That process takes 3–5 minutes per carrier reply. On a load with 30 replies, that's 90–150 minutes of compliance checking before a single carrier is ranked.
The compliance gap isn't that coordinators don't know what to check — they do. The gap is that manual checking at this volume leads to skipped steps under time pressure. Keelway doesn't skip steps. Every reply gets the full stack, every time, before the coordinator sees the ranked list.
Hazmat-class-specific compliance flags
Not all hazmat is the same. Class 3 flammable liquids, Class 8 corrosives, and Class 2 compressed gases each have different carrier requirement profiles. Keelway's hazmat vetting is class-aware:
- Class 1 (Explosives) — high-scrutiny flag, manual verification recommended before booking, in addition to authority check.
- Class 2 (Gases) — tank vehicle endorsement check where applicable, pressure-vessel equipment verification.
- Class 3 (Flammables) — standard hazmat authority check, insurance adequacy for flammable liquid minimums.
- Class 6 (Toxic) — elevated insurance minimum check, route restriction flags for populated corridors.
- Class 7 (Radioactive) — maximum scrutiny flag, NRC-permit awareness, manual verification required.
TMS write-back and compliance record-keeping
When a hazmat carrier is accepted, Keelway writes the carrier record — including hazmat endorsement status at time of booking, confirmed insurance level, and any route or placard notes captured from the email thread — back to your TMS. For Tai, McLeod, Aljex, Revenova, Turvo, and Rose Rocket this happens automatically without a coordinator retyping anything. The compliance record is in the load file from the moment of booking.
Who uses Keelway for hazmat brokerage
Chemical company 3PL arms, petroleum and fuel distributors with brokerage operations, industrial gas shippers, and independent hazmat freight brokerages running mixed-class books. The common thread: hazmat compliance is non-negotiable, manual checking at scale creates exposure, and coordinators need a trust layer they can run at inbox speed.

Frequently asked questions
How does Keelway verify hazmat endorsements on carrier replies?+
Every carrier that replies to a hazmat-posted load is cross-referenced against FMCSA operating authority records for hazmat-specific endorsements and hazmat cargo authority. Carriers that hold standard freight authority but not hazmat authority are flagged before they appear in the ranked list. Keelway also checks whether the carrier's insurance on file includes the higher liability limits typically required for hazardous materials shipments.
What about placarding requirements — does Keelway check those?+
Keelway reads the UN number, hazard class, and packing group from the load record and flags when a carrier's reply doesn't acknowledge placard requirements or when the carrier's equipment is not rated for the hazard class in the load. This doesn't replace your team's regulatory review, but it catches carriers that clearly aren't equipped for the specific hazmat classification before the coordinator invests time in a booking conversation.
How does Keelway handle route restriction checks for hazmat loads?+
Hazmat routing restrictions — tunnel bans, bridge bans, urban routing rules under FMCSA 397 — vary by hazard class and route. Keelway flags carriers whose stated routes include known restricted segments for the relevant hazard class, and surfaces any route-related language in the carrier's email reply in the inquiry detail view for coordinator review. This is a first-pass flag, not a formal route compliance check.
Why is fraud risk higher on hazmat loads?+
Hazmat rates are structurally above market due to the compliance burden, insurance cost, and driver certification requirements. That rate premium attracts fraudulent operators who claim hazmat authority they don't hold. Keelway runs MC-DOT mismatch detection, domain spoofing checks, and sudden lane-change signals on every hazmat reply — the same signal set described in our chameleon carrier research. Carriers quoting hazmat loads without hazmat endorsements on file are flagged before they reach the ranked list.
Does Keelway check driver-level hazmat endorsements?+
Keelway checks carrier-level FMCSA hazmat authority. Driver-level CDL hazmat endorsement verification requires CDLIS access, which is a separate compliance system. We surface the carrier-level signal; driver-level endorsement confirmation should still be part of your pre-dispatch checklist. We document this clearly in the ranked row so coordinators know what's been checked and what hasn't.
Can Keelway handle Class 1 explosives, Class 7 radioactive, and other restricted hazmat classes?+
Keelway flags hazard class from the load record and checks carrier authority against the class. For extremely restricted classes (Class 1, Class 7, some Class 6 materials), Keelway will surface a high-compliance-scrutiny flag and recommend manual verification before booking, in addition to the automated authority check.
Does Keelway integrate with the TMS platforms hazmat brokerages use?+
Yes. Pre-built integrations with Tai, McLeod LoadMaster, Aljex, Revenova, Turvo, and Rose Rocket. Accepted carrier, confirmed rate, hazmat endorsement status, and any routing or placard notes captured from the email thread are written back automatically. No retyping.
Pricing?+
Per-coordinator seat. No per-load, per-email, or per-carrier charges. Hazmat-focused brokerages start under four figures monthly. We share firm numbers on the first demo call.
