Who the rules cover

What counts as hazardous material and transportation

A hazardous material (hazmat) is a substance or material that the Secretary of Transportation has found can pose an unreasonable risk to health, safety and property when transported in commerce, and has designated as hazardous. It includes:

The HMR are parts 171 through 180 of Title 49.

Transportation is more than driving

Transportation means moving property, plus the loading, unloading and storage that go along with that movement. And commerce includes trade or transportation within a single state, not only across state lines.

Reference: 49 CFR 171.8 "Hazardous material" · 49 CFR 171.8 "HMR" · 49 CFR 171.8 "Transportation or transport" · 49 CFR 171.8 "Commerce"

Who the rules cover

Hazmat employees and hazmat employers

You are a hazmat employee if you work full time, part time or on a temporary basis for a hazmat employer (or are self-employed) and your work directly affects hazardous materials transportation safety. That includes anyone who:

Handles itLoads, unloads or handles hazardous materials.
Prepares itPrepares hazardous materials for transportation.
Is responsibleIs responsible for the safety of transporting hazardous materials.
Drives itOperates a vehicle used to transport hazardous materials.

People who design, make, inspect, mark, repair or test packaging represented, marked, certified or sold as qualified for hazmat are covered too.

Hazmat employer

A hazmat employer employs or uses at least one hazmat employee and transports hazmat in commerce, causes it to be transported, or makes or tests qualified hazmat packaging. Federal, state, local and tribal government agencies can be hazmat employers too.

Reference: 49 CFR 171.8 "Hazmat employee" · 49 CFR 171.8 "Hazmat employer"

Shipping jobs that are regulated

Pre-transportation functions

A pre-transportation function is a job required by the HMR to make sure hazmat travels safely. If you do any of these, the rules apply to your work:

Classify and packDetermine the hazard class. Select the packaging. Fill it. Secure the closure, even on a container with only residue left.
CommunicateMark and label packages. Prepare a shipping paper. Provide and maintain emergency response information. Review a shipping paper for compliance.
Certify and importCertify that the material is in proper condition for transportation. For importers: give the shipper timely, complete information about the U.S. rules that will apply.
Load the vehicleLoad, block and brace packages in a freight container or transport vehicle. Separate them from incompatible cargo. Select, provide or put on placards.

Reference: 49 CFR 171.8 "Pre-transportation function"

Shipping jobs that are regulated

Shipping words you will hear

Bulk or non-bulk?

Non-bulkFor a liquid: a maximum capacity of 450 L (119 gallons) or less.
BulkFor a liquid: a maximum capacity greater than 450 L (119 gallons). Cargo held with no intermediate container in a transport vehicle or freight container is bulk too.

Solids and gases have their own size limits in the definitions.

Reference: 49 CFR 171.8 "Shipping paper" · 49 CFR 171.8 "Marking" · 49 CFR 171.8 "Packaging" · 49 CFR 171.8 "Package or Outside Package" · 49 CFR 171.8 "Non-bulk packaging" · 49 CFR 171.8 "Bulk packaging"

Hazard words

Key terms in the HMR

These words show up on shipping papers, in the Hazardous Materials Table and in your training. Learn what each one means.

Reference: 49 CFR 171.8 "Hazard class" · 49 CFR 171.8 "Division" · 49 CFR 171.8 "Primary hazard" · 49 CFR 171.8 "Subsidiary hazard" · 49 CFR 171.8 "Packing group" · 49 CFR 171.8 "Proper shipping name" · 49 CFR 171.8 "Limited quantity" · 49 CFR 171.8 "Undeclared hazardous material"

The five parts of training

What hazmat training must include

1. General awareness / familiarization

Every hazmat employee. Makes you familiar with the HMR and able to recognize and identify hazardous materials. This course covers general awareness topics.

2. Function-specific

Every hazmat employee. Covers the rules, exemptions or special permits that apply to the exact jobs you do, such as preparing shipping papers or loading vehicles.

3. Safety

Every hazmat employee. Covers emergency response information, how to protect yourself from the hazardous materials you may be exposed to (including your employer's specific measures), and how to avoid accidents, such as handling hazmat packages properly.

4. Security awareness

Every hazmat employee. Covers security risks in hazmat transportation, ways to improve security, and how to recognize and respond to possible security threats. New hazmat employees must get it within 90 days after employment.

5. In-depth security

Only for employees of companies required to have a security plan, who handle or perform regulated functions for hazmat covered by the plan, or who carry out the plan. Covers company security objectives, structure, procedures, each person's duties, and what to do if security is breached.

Reference: 49 CFR 172.704(a)(1) · 49 CFR 172.704(a)(2) · 49 CFR 172.704(a)(3) · 49 CFR 172.704(a)(4) · 49 CFR 172.704(a)(5)

The five parts of training

Other training that may count, and some limits

Other training can count

Training your employer gives to meet OSHA hazard communication rules (29 CFR 1910.120 or 1910.1200), EPA rules (40 CFR 311.1), or other federal or international security training may be used to meet DOT's training requirements, but only to the extent it covers the DOT training components.

For function-specific training, training on the ICAO Technical Instructions and the IMDG Code may be used instead, to the extent it covers functions allowed under part 171, subpart C.

A few limits

Reference: 49 CFR 172.704(b) · 49 CFR 172.704(a)(2)(ii) · 49 CFR 172.704(e)(1) · 49 CFR 172.704(e)(2)

Deadlines and records

When training must happen

New job or new duties

A new hazmat employee, or one who changes job functions, may do those functions before training is finished only if both of these are true:

Refresher

Hazmat training must be repeated at least once every three years. For in-depth security training, if the security plan is revised during that cycle, training on the revised plan is due within 90 days of putting it in place.

Training from somewhere else

Relevant training from a previous employer or another source can count, if a current record of that training is obtained from the previous employer.

Remember: The hazmat employer is responsible for following the HMR whether or not your training is finished.

Reference: 49 CFR 172.704(c)(1) · 49 CFR 172.704(c)(2) · 49 CFR 172.704(c)(3) · 49 CFR 172.704(c)(4)

Deadlines and records

The training record

Your employer must create and keep a record of your current training, covering the preceding three years. It must be kept for as long as you work there as a hazmat employee and for 90 days after. On request, it must be made available at a reasonable time and place to an authorized DOT official or other entity explicitly given authority to enforce the HMR.

The record must include

Reference: 49 CFR 172.704(d) · 49 CFR 172.704(d)(1) · 49 CFR 172.704(d)(2) · 49 CFR 172.704(d)(3) · 49 CFR 172.704(d)(4) · 49 CFR 172.704(d)(5)

Fact-checked against the regulation text on October 09, 2026. This certificate records completion of awareness training based on DOT 49 CFR 172.704 and 171.8. It is not an OSHA card or license, and it does not by itself meet the training requirements of 49 CFR 172.704. Your hazmat employer must still provide the function-specific, safety and security awareness training required by 172.704(a), and in-depth security training if you are covered by a security plan; keep a record of your current training that includes certification that you have been trained and tested; and repeat the training at least once every three years.

This guide explains the rule in plain words. Always read the regulation itself and your employer's site-specific procedures.
