New PHMSA hazmat rules go into effect September 3, 2026
PHMSA just finalized 16 rules under the HM-268 package, and while most of it is deregulatory cleanup, 4 changes will directly affect daily operations for hazmat carriers:
Smaller limited quantity labels now allowed
No more separate permits for discharging while packaging stays mounted on the vehicle
Cylinder requalification intervals extended from 5 to 10 years (with conditions)
New documentation requirement for empty residue IBCs
Save this for your safety team, and drop a comment if you want the full breakdown on the other provisions (aerosols, refrigerants, lithium batteries, and more).
