Hazmat emergency response telephone number: the line that has to answer

The declaration is signed and the diamonds match the paper. The only telephone on the form is the sales desk, or the number sits on a safety data sheet in the pouch and never reaches the form. That is the hazmat emergency response telephone number problem. A responder at two in the morning cannot use a mailbox, and an acceptance desk can send the freight back before anyone opens the drum. If the carrier already returned the paper, the correction still starts on that form: https://altor.consulting/rejected.html.

What the regulation actually requires

This is 49 CFR 172.604 on the eCFR text current as of 15 October 2026. Title 49 was last amended 13 October 2026. The note on 172.604 itself runs through 11 May 2020. The section was not rewritten on that October date.

The offeror provides a numeric telephone number, area code included. Outside the United States, add the access code or the plus sign, the country code, and the city code needed to complete the call. Someone monitors it the whole time the material is in transportation, including storage incidental to transportation. The person who answers knows the material, or reaches a person who does on that same call. Paragraph (a) refuses a number that waits on a return call. An answering machine, a service that only takes a message, or a pager fails it.

The number goes on the shipping paper, immediately after the description, or once where a reader can find it quickly. That single entry is allowed only when the number covers every hazardous material on the paper and the paper shows it is the emergency contact. For air, the paper is the Shipper's Declaration. A handling note works as the single entry only on those same terms.

If the offeror is the provider, paragraph (b) wants the offeror's name with the number, or elsewhere and easy to find. If an outside organization answers, it has to be able to give the information and it has to have accepted the job. The registered person gives that organization current information on the material before the offer. The paper shows the registered name, or the contract number or other identifier the provider assigned, beside the number unless it is already prominent. Under paragraph (c), the person who prepares the next shipping paper includes this information. Taking on the number means meeting the whole section. A booking does not move the duty by itself.

Paragraph (d) turns the section off for limited quantities, excepted quantities, and a closed list of shipping names. Dry ice, consumer commodity, battery powered equipment, battery powered vehicle, and wheelchair, electric are on the list. Lithium ion batteries are not. A fumigated unit that shows the fumigant mark, with no other hazardous material inside, is out too. A telephone on an old lithium battery mark is not this number.

49 CFR 172.600(d) drops subpart G when the material is excepted from shipping papers. 49 CFR 173.185(c) excepts a smaller lithium package that meets the paragraph from part 172 subparts C through H, except where (c) says otherwise. On air, (c)(5) returns smaller standalone cells and batteries to the applicable requirements of the subchapter. The packaging relief in that paragraph is not a telephone relief. Paragraph (c)(4), packed with or contained in equipment, does not bring this section back. Read both before you omit the number. Size limits stay in (c)(1) and are not restated here.

49 CFR 172.602 is the information beside the telephone: the description, the health effect, fire or explosion, the first steps, and first aid, in English, available away from the package. A safety data sheet can carry it. So can a guide tied to the paper, including ICAO aircraft incident guidance aboard an aircraft. None of that removes the number from the shipping paper. A US offer under the ICAO Technical Instructions still meets subpart G where it applies. That is 49 CFR 171.22(g)(1).

The mistake

Desks treat the safety data sheet as the telephone. The sheet can carry 172.602 information. It is not the 172.604 entry on the shipping paper. The printed number rings a switchboard, a mailbox, or a service that calls back later. A contract center appears without the registered name or identifier, or without current information sent before the offer. One number covers a second hazardous material the center was never told about. Dry ice or battery powered equipment is used as a pass for a different shipping name. A limited quantity exception is borrowed for a line that was never prepared that way. An international number is typed as a domestic string, so the call cannot be completed.

How to place the hazmat emergency response telephone number

Confirm scope first. Limited quantity, excepted quantity, and a name 172.604(d)(2) actually lists are out. A similar name stays in. For lithium, separate a package that meets 173.185(c) from a fully regulated one, and on air separate (c)(4) from (c)(5).

Name who answers. Your own people, on duty while the freight moves and while it sits in storage incidental to transportation. Or a provider that already holds current information on this material and has accepted the calls.

Write the number on the declaration in one of the two ways above, with the name or identifier paragraph (b) requires, and with the country code when the number is foreign. Leave the 172.602 information where someone can use it away from the package.

49 CFR 173.22 leaves classification with the offeror. Sign under 172.204. On air, 172.204(c)(3) and IATA DGR 8.1.6.12 are the certification. Correct a mailbox number before that signature.
