The Pipeline and Hazardous Materials Administration is expanding the data on hazardous materials shipped across the U.S.
PHMA’s Office of Hazardous Materials Safety (OHMS) worked with the U.S. Census Bureau to build out the 2022 Commodity Flow Survey to include supplemental questions about hazardous materials and collect new data from hazmat shippers that use Department of Transportation-regulated specification packaging. PHMA is a division under DOT.
Based on this new data collection, the Census Bureau and OHMS together developed a unique dataset for public release, which they jointly published as the 2021-2022 Expanded Hazmat Supplement (EHM). The Census Bureau published the new data as an Experimental Data Product” on their website here.
You can also download the data and supporting documentation here:

The 2021-2022 Expanded Hazmat Supplement is a pilot project supported by the OHMS Research, Development & Technology program. PHMSA welcomes your suggestions for improvement and other feedback. Additionally, PHMSA is interested in learning how you or your organization plan to use the new 2021-2022 EHM data.
Questions and feedback can be sent via e-mail to the OHMS RD&T team at [email protected].
