Harmonizing the HMR: A Look at Final Rule HM-215Q
The Pipeline and Hazardous Materials Safety Administration (PHMSA) published final rule HM-215Q on April 10, 2024. Changes included with this final rule will harmonize the Hazardous Materials Regulations (HMR) with international dangerous goods regulations.
Harmonization facilitates international trade by the burdens of complying with multiple or inconsistent safety requirements for transportation of hazardous materials. Also, it’s estimated that harmonization will save up to $130 million in shipping costs.
Mandatory compliance for the final rule is April 10, 2025, with voluntary compliance retroactive to January 1, 2023.

- Review the changes.
- Determine if the changes will affect your operations.
- Develop a plan to implement the changes.
