What OSHA Requires for Your SDS Emergency Phone Number
Every safety data sheet for a hazardous chemical must display an SDS emergency phone number in Section 1, here's exactly what the regulation says, and what "compliant" actually means.
Under OSHA's Hazard Communication Standard, 29 CFR 1910.1200, Appendix D, every safety data sheet must include the following information in Section 1 (Identification):
(a) Product identifier used on the label
(b) Other means of identification
(c) Recommended use of the chemical and restrictions on use
(d) Name, address, and telephone number of the chemical manufacturer, importer, or other responsible party
(e) Emergency phone number.
The regulation itself doesn't specify who must answer the SDS emergency number or what hours it must be staffed, but OSHA's interpretation letters and DOT's transportation regulation, 49 CFR 172.604, layer additional requirements on top for chemicals in transit: the number must be monitored at all times the hazmat is in transportation, and the person who answers must be knowledgeable about the chemical (or have immediate access to someone who is). For the full picture of who must provide an SDS and what every section requires, see our SDS compliance requirements guide.
In practice, this means the SDS emergency contact number listed on your safety data sheets should be answered by a live person 24/7, not voicemail, not a call-back service. Most companies satisfy this by using a dedicated emergency response provider, so a single SDS emergency phone number can cover every safety data sheet you produce.
Still seeing "MSDS" on legacy documents? MSDS (Material Safety Data Sheet) is the pre-2012 term. OSHA adopted the Globally Harmonized System (GHS) in 2012 and renamed them to SDS (Safety Data Sheets). The emergency phone requirement is identical either way, the MSDS emergency phone number on older documents is the same regulatory obligation as today's SDS emergency phone number. If you still use MSDS labeled "MSDS 800 number" fields, those must be answered 24/7 by a knowledgeable person too.

"Legacy Providers" refers to traditional 24-hour emergency response phone providers in the U.S. hazmat industry. Pricing and service comparisons are based on publicly available information as of November 2026. We encourage all prospects to contact providers directly for official quotes.
Legacy Providers
The traditional model, emergency response bundled into broader EHS platforms with tools most SDS-only customers don't use.
Legacy providers have been in the market for decades and typically bundle emergency response into broader EHS management platforms, with chemical inventory software, SDS authoring, and regulatory reporting packaged together. Their pricing reflects the full suite, not just the emergency phone service. Product-label use of your emergency number is usually billed separately, SDS-on-file counts are capped, and the year-round regulatory helpdesk, where offered, sits behind a separate paid tier.
Worth knowing: Legacy pricing typically starts above $1,000/year and is not publicly listed, you'll need to contact sales for a quote. If your organization already runs on one of these platforms and wants emergency response bundled in, that model works. If you just need a compliant SDS emergency phone number without the EHS suite, you're paying for capabilities you may not use.
HAZMAT LINE
Built specifically for shippers who need a compliant SDS emergency phone number, with year-round regulatory support and transparent pricing.
HAZMAT LINE was built around a simple idea: a hazmat emergency phone provider should give you everything you need to stay compliant and prepared, not just a number that sits on your SDS until something goes wrong. Plans start at $599/year and include unlimited SDS on file, unlimited business units, and a live regulatory helpdesk you can call year-round for questions about labeling, shipping classifications, and SDS content. Proactive drill calls let you test your response readiness before a real incident happens.
HAZMAT LINE operates globally with offices in the USA and Brazil. When an international responder calls your SDS emergency telephone number, they speak with a hazmat specialist in their native language, no interpreter delays. Battery shippers get a dedicated program that includes labeling coverage at no extra charge.
Worth knowing: HAZMAT LINE is focused on emergency response and year-round regulatory support, not a full EHS management platform. We don't sell SDS authoring software for you to write safety data sheets in-house. If you need SDSs authored or revised, we can arrange it for you through our vetted partner network. For companies whose primary need is a compliant SDS emergency phone number with year-round regulatory support and transparent pricing, HAZMAT LINE delivers more value at a lower cost.
