Summary of requirements
The agencies listed here are responsible for enforcing or supporting the Hazardous Materials Regulations (HMR). Some focus on a single mode of transportation, for example, the FAA oversees air transport, while the FMCSA handles highway shipments. Others, like PHMSA, cover multiple modes and coordinate with other agencies to ensure safe hazmat transport. It’s important to understand which agencies regulate your operations and stay in compliance with their requirements.
