In preparation for the 1st of January when they take effect, IATA has released a summary of the main changes incorporated into the 60th Edition of IATA’s Dangerous Goods Regulations for air transport.

The changes broadly reflect the main UN changes across all transport modes, with the addition of air-specific changes and operator conditions.
