RIN 2137–AG05 Hazardous Materials: Reducing Burdens on Domestic Companies Using Battery-Powered Equipment in Trades
ACTION: Final rule.
SUMMARY: This final rule modernizes the Materials of Trade (MOT) exception in the Hazardous Materials Regulations (HMR) by increasing the maximum allowable quantities of lithium batteries that can be transported as MOTs. This increase removes an undue regulatory burden which constrains the ability of construction, landscaping, mowing, tree service, food service, and entertainment companies to perform their trade.
DATES: This final rule is effective September 3, 2026.
