X3 HazMat is part of the X3 compliance family. One X3 HazMat API key puts the compliance engine in your software — classify any UN number, get the required placards, check segregation (§177.848), validate a full shipment, and generate shipping papers — through simple REST calls, every answer cited to the exact 49 CFR section. Built for TMS, ELD, and shipping platforms.

X3 HazMat covers PHMSA hazmat compliance — placards, shipping papers, security plans. A dedicated hazmat classification & document generation endpoint is rolling out on the same key — tell us your use case and we'll enable it for your account.
One key, every X3 engine. Billed monthly by call volume.
Keys are self-serve. Sign in to the X3 API console, create a sandbox key free, and upgrade to Starter, Growth or Scale any time with secure Stripe checkout.
