## Who Must Register

You must register if you are a person who offers for transportation or transports in commerce a shipment containing any of the following categories of hazardous materials (including hazardous wastes):
                      - A  highway route controlled quantity  of a Class 7 (radioactive) material, as defined in 49 CFR 173.403. A "highway route controlled quantity" may be shipped by highway, rail, air, or water.
                      - More than 25 kilograms (55 pounds) of a Division 1.1, 1.2, or 1.3 (explosive) material (see 49 CFR 173.50) in a motor vehicle, rail car, or freight container.
                      - More than one liter (1.06 quarts) per package of a "material extremely toxic by inhalation" (that is, a "material poisonous by inhalation" that meets the criteria for "hazard zone A" as specified in 49 CFR 173.116(a) for gases or 173.133(a) for liquids).
                      - A hazardous material (including hazardous wastes) in a  bulk packaging  having a capacity equal to or greater than 13,248 liters (3,500 gallons) for liquids or gases or more than 13.24 cubic meters (468 cubic feet) for solids. Please note that persons who offer or transport hazardous materials that do not require placarding (that is, Class 9 materials) in a bulk packaging with a capacity greater than 3,500 gallons or 468 cubic feet, must register.
                      - A shipment in other than a  bulk packaging  of 2,268 kilograms (5,000 pounds) gross weight or more of one class of hazardous materials (including hazardous wastes) for which placarding of a vehicle, rail car, or freight container is required for that class.
                      - A quantity of hazardous material that requires placarding.The offering and transporting of hazardous materials by  farmers  in direct support of their farming operations are excepted from this category of activities requiring registration. See the information on requirements for  farmers  below.

Since the beginning of the program in 1992, activities in Categories A through E above have required registration by law. Category F was added by regulation beginning with the 2000-2001 registration year.

**Exceptions:** The following are specifically excepted by statute or regulation from the registration requirements:
                      - Agencies of the federal government.
                      - Agencies of states.
                      - Agencies of political subdivisions of states.
                      - Indian tribes.
                      - Employees of those entities listed in [A], [B], [C], or [D] who offer or transport hazardous materials as part of their official duties.
                      - Hazmat employees, including the owner-operator of a motor vehicle that transports hazardous materials in commerce if that vehicle, at the time of those activities, is leased to a registered motor carrier under a 30-day or longer lease as prescribed in 49 CFR Part 376 or an equivalent contractual relationship.
                      - A person who offers hazardous materials for transportation to the United States solely from locations outside of the United States, when that person is domiciled outside the United States, in a country that does not impose registration or a fee on U.S. companies for offering hazardous materials into that country.
                      - A  farmer  who offers or transports only hazardous materials that are used in direct support of his or her farming operations and who is not engaged in activities included in Categories A through E described in "Who Must Register" above.

A **farmer** must register if he or she:
                      - Offers or transports hazardous materials that require placarding that are not in direct support of his or her farming operation. For example, a farmer who offers or transports home heating fuel for commercial purposes in quantities requiring placarding must register.
                      - Offers or transports for any purpose any of the hazardous materials included in Categories A through E of "Who Must Register" above. For example, a farmer who transports 55 lbs or more of a Division 1.1 explosive, even if the explosive is to be used in direct support of his farming operations, must register.

**Clarifications**: The HMR apply to persons who offer for transportation or transport by highway, rail, water, or air. Water transportation does not include hazardous materials loaded or carried on board a vessel without benefit of containers or labels and received and handled by the vessel carrier without mark or count. This type of shipment, for which the vessel is the container, such as LNG or oil tanker vessels, is under the authority of the U.S. Coast Guard in the Department of Homeland Security.

The term "person" means each separate legal entity, such as a corporation, partnership, association, or LLC or LP. This means that a separately incorporated subsidiary (or LLC or LP) must register if it engages in the specified activities, even when a parent company is also required to register. All locations and vehicles operated by a person are covered by that person's registration.

You must also register if you engage in any of the activities discussed in "Who Must Register" above, and you are:
                      - A merchant vessel carrier transporting, transiting, or transhipping hazardous materials within 12 miles of the U.S. coast; or
                      - A federal, state, or local government contractor.

**Requirements for Hazardous Waste Generators:** All hazardous wastes subject to the Hazardous Waste Manifest Requirements of the U.S. Environmental Protection Agency (EPA) are hazardous materials. A hazardous waste generator must register if you meet the requirements identified above.

## Company Search

## Current Year

The 2024-2025 Registration Year covers the period between July 1, 2024, and June 30, 2025.

Register before July 1, 2024, or before engaging in any of the activities requiring registration, whichever is later.

## Background and Use of the Fee

Under the federal hazardous material transportation law (49 U.S.C. 5101 et seq.), offerors and transporters of certain types and quantities of hazardous materials, including hazardous wastes, are required to file a registration statement with the U.S. Department of Transportation and to pay an annual fee. This program began in 1992 and is administered by the Associate Administrator for Hazardous Materials Safety, Pipeline and Hazardous Materials Safety Administration (PHMSA). The registration regulations are found at 49 CFR 107.601-107.620.

The fee provides funds for grants distributed to states and Indian tribes for hazardous materials emergency response planning and training and to certain professional organizations for training purposes through the Hazardous Materials Grants Program. **Your fee is helping communities prepare for hazardous materials incidents or other emergencies that may occur**.

Information about the Grants Program, funded by the registration fees, is available here.

## Other Requirements

### **Registration Deadline**

The completed 2024-2025 (or 2024-2026 or 2043-2027) registration statement and payment must be submitted before July 1, 2024, or before engaging in any of the activities requiring registration, whichever is later.

### **Recordkeeping Requirements**

Copies of the registration statement and the certificate of registration must be kept for three years at your principal place of business and must be available for inspection. Motor carriers and vessel operators must also have on board a copy of the current certificate of registration, or another document bearing the current year's registration number identified as the "U.S. DOT Hazmat Reg. No." Every truck or truck tractor or vessel you use for the transportation of a hazardous material that meets the registration criteria must have this proof of registration on board.

### **If You Have Failed To Register For Past Years**

Companies that failed to register for previous years in which they engaged in activities that required registration must register for those years and pay the appropriate fee.

If you engaged in any of the hazardous materials activities in categories A through E in registration years before 2000-2001, or if you engaged in any of the activities in categories A through F in registration years 2000-2001 through 2023-2024, but did not register, you must do so now.

### **For Failure To Register**

The requirement to register with DOT is based on a federal law. The enforcement of this requirement is conducted cooperatively by federal, state, and local agencies. Federal, state, or local officials may impose penalties for failing to register or failing to meet the recordkeeping requirements.

## Related Programs

### **FMCSA Hazardous Materials Safety Permits**

Highway carriers of certain types of hazardous materials are required to obtain a Hazardous Materials Safety Permit from the Federal Motor Carrier Safety Administration (FMCSA). Some (but not all) of the activities that require a highway carrier to register with PHMSA also require the carrier to obtain a safety permit from FMCSA. All companies that are required to have an FMCSA Safety Permit are required to have a PHMSA Registration. Some highway carriers will need only a PHMSA registration. For further information on the FMCSA Hazardous Materials Safety Permit requirements, click here. A printable brochure is available here.

### **State Registrations**

Some states have hazardous materials registration or permitting programs that may also apply to you. Registration with PHMSA does not replace state requirements.

### **Hazardous Materials Security Plans**

Companies that are required to register may also be required to have written security plans that include a risk assessment and measures to address personnel security, unauthorized access, and en route security. Companies that are required to have security plans must also provide security training to all hazmat employees. This training is one element of the training required for all hazmat employees in 49 CFR 172.704.

### Hazardous Materials Incident Reports

A person in possession of hazardous materials at the time of an incident during transportation which results in serious consequences must immediately report the incident (see 49 CFR 171.15). These incidents and others require the filing of a detailed incident report within 30 days of the incident (see 49 CFR 171.16).

### To Obtain a U.S. DOT or MC/MX Number

Call the local Federal Motor Carrier Safety Administration's (FMCSA) office (usually in your state capitol). See the list of FMCSA field offices.

The application for a US DOT or MC/MX number can be filed electronically at http://safer.fmcsa.dot.gov/. Select "FMCSA Registration & Updates" under "FMCSA Services." USDOT and MC/MX numbers can be verified at that same site by selecting "Company Snapshot" under "FMCSA Searches".
