On October 1, US DOT PHMSA released a hazmat enforcement policy to permit offerors and carriers to comply with editions of the ICAO Technical Instructions (TI) and the IMDG Code that have not yet been incorporated into the 49 CFR Hazardous Materials Regulations (HMR) when shipping by air and vessel.
The policy reads, in part:
“PHMSA will not take enforcement action against any offeror or carrier who offers or accepts for domestic or international transportation by any mode packages marked or labeled in accordance with these standards.”
Read the full
PHMSA Notice of Enforcement.
PHMSA will evaluate whether to include revisions in the 2021-2022 ICAO TI and/or the forthcoming Amendment 40-20 of the IMDG Code in a future rulemaking.
2021 IATA DGR (62nd Edition)
Most hazmat/dangerous goods air shippers use the International Air Transport Association’s
Dangerous Goods Regulations (IATA DGR) to prepare and offer hazardous materials shipments. The IATA DGR combines the ICAO Technical Instructions with state and operator variations that hazmat air shippers must know for their shipments to be accepted for air transport.
The 62
nd Edition IATA DGR takes effect on January 1, 2021 and is available for pre-order now.
