Choosing a Hazmat Emergency Phone Number Provider: What Each Option Brings to the Table
CHEMTREC®
The industry incumbent, established 1971, owned by the American Chemistry Council
CHEMTREC is the name most people think of when they hear "hazmat emergency phone number." They've been operating for over 50 years and maintain one of the largest SDS libraries in the industry with over seven million documents on file. Their 24/7 operations center handles hundreds of calls daily and offers interpreter services in 240+ languages. Beyond emergency response, CHEMTREC also offers SDS authoring, online hazmat training courses (DOT, IATA, IMDG, OSHA), and consulting services, all available as separate, paid add-ons.
Worth knowing: CHEMTREC's base price starts at $1,040/yr, but the real cost often comes from add-ons, per-affiliate fees, per-contact charges, and zone-based pricing for international coverage can add up quickly. There's no regulatory helpdesk included between incidents, and no proactive drill calls to test your team's readiness. Language support during emergencies is routed through third-party interpreters rather than native-speaking hazmat specialists. If your company ships across multiple business units or regions, request a detailed quote that accounts for all surcharges before comparing.
Chemtel (VelocityEHS)
Part of the VelocityEHS Accelerate® platform, originally founded in 1988
Chemtel has been providing 24-hour emergency response services since the late 1980s and is now part of the VelocityEHS suite of EHS management tools. Their call center is staffed by experts, and they offer unlimited business units under a single plan. Chemtel also provides SDS authoring, regulatory consulting, and access to a broader EHS software platform that includes chemical inventory management, GHS labeling, and regulatory reporting, useful if your organization needs a full compliance suite beyond just an emergency number.
Worth knowing: Chemtel's roots are in SDS management and OSHA workplace compliance, their platform is strongest for facility-based incidents and chemical inventory tracking. If your primary need is a DOT-compliant emergency response number for transportation, that's a narrower slice of what VelocityEHS is built around. Pricing starts above $1,000/yr and is not publicly listed, you'll need to contact their sales team for a quote. There are also extra charges for displaying your 24-hour number on product labels, limits on the number of SDS they'll keep on file, and the regulatory helpdesk is available but billed as a separate service. If you only need a hazmat emergency phone number and don't plan to use the broader EHS platform, you may end up paying for tools you don't use.
HAZMAT LINE
The modern alternative, built for shippers who want more included at a lower price
HAZMAT LINE was built around a simple idea: a hazmat emergency phone number provider should give you everything you need to stay compliant and prepared, not just a number that sits on your shipping papers until something goes wrong. Plans start at $599/yr and include unlimited SDS on file, unlimited business units, a live regulatory helpdesk you can call year-round (not just during emergencies), and proactive drill calls to test your response readiness before a real incident happens.
HAZMAT LINE operates globally with offices in multiple regions and native-speaking hazmat specialists for major languages, so when an emergency call comes in from an international responder, they're speaking directly with a specialist in their own language, not waiting for an interpreter to be patched in. Companies also get access to discounted rates on cleanup and training through a vetted partner network with no referral fees or conflicts of interest.
Worth knowing: HAZMAT LINE does not author SDSs in-house; we arrange authoring and revisions through our vetted partner network. That said, for companies whose primary need is a compliant hazmat emergency phone number with year-round regulatory support and transparent pricing, HAZMAT LINE delivers more value at a lower cost than either CHEMTREC or Chemtel.
