When a hazmat shipment is involved in a crash, leak or fire, first responders need to know what is in the load, fast. The emergency response telephone number on the shipping paper is how they get that answer. It is also one of the most frequently botched items on hazmat documents.
This guide explains what the U.S. rule in 49 CFR 172.604 expects and the mistakes we see most often with South Florida shippers.
What the rule says
For most hazardous materials shipments, the shipping paper must include an emergency response telephone number. That number must be:
- Monitored at all times while the hazardous material is in transportation, including storage incidental to transportation.
- Answered by a person who is knowledgeable of the hazards and characteristics of the material, or who has immediate access to a person who is.
- Able to provide detailed information about handling a spill or incident, including immediate precautions and mitigation steps.
The number must be entered on the shipping paper in the manner the regulations specify, generally next to the basic description or in another prominent place. Some exceptions exist, so check the regulation for your specific material and mode.
Why this matters in the real world
First responders rely on the shipping paper and the Emergency Response Guidebook (ERG) for initial actions. The ERG gives general guidance by UN number, but the emergency contact can supply product-specific information. Our post on shipping papers and the ERG explains how the two work together.
Your options for a compliant number
Shippers generally use one of these approaches:
- A number staffed by your own company, if someone qualified is truly available around the clock, including nights, weekends and holidays.
- A subscription emergency response service, such as a third-party provider that registers your products and answers 24/7. CHEMTREC is a well-known example, though other providers exist.
- The manufacturer’s number, when the product comes from a manufacturer that provides a monitored line and has authorized you to use it.
Whichever you choose, make sure the provider knows your products are registered and that their answering staff can access your SDS data.
Common mistakes
- Business-hours-only lines. A mobile phone or office line that goes to voicemail at 5 p.m. does not meet the requirement.
- Unregistered products. Paying for a service but not registering the product means the responder may not have SDS information to give.
- Wrong or outdated numbers. Old templates carry old phone numbers. Update every document template when you change providers.
- Missing from the shipping paper. The number must be on the paper that travels with the load, not just in your internal records.
- Using a number you do not have permission to use. Do not copy another company’s emergency contact onto your documents.
Air and ocean shipments
For air shipments under IATA rules, the Shipper’s Declaration for Dangerous Goods includes a 24-hour contact requirement, and ocean shipments under the IMDG Code have their own documentation requirements. A mismatch between the declaration and the booking system can delay cargo at MIA or the ports. See our overview of the IATA shipper’s declaration errors that ground cargo at Miami.
A simple annual audit
Once a year, and any time you change a provider, do this:
- Call your own emergency number at night and on a weekend to confirm that a knowledgeable person answers.
- Confirm that every product on your active SKU list is registered.
- Update templates, bills of lading and electronic shipping systems.
- Train anyone who signs shipping papers on what the number is and why it matters.

Frequently asked questions
Can I use my cell phone as the emergency response number?
Only if it meets the monitoring requirement, meaning it is answered at all times while the material is in transportation by a person who knows the hazards or has immediate access to someone who does. In practice, most shippers use a dedicated service.
Is CHEMTREC required for hazmat shipping?
No. The regulation requires a compliant 24-hour number, not a specific provider. CHEMTREC is one of several services that can fulfill the requirement.
Does the emergency number go on every shipping paper?
For most hazardous materials shipments it does, but there are exceptions in the regulations. Confirm the requirement for your specific material and mode of transport.
