DG Digest: IATA publishes an addendum to the 64th Edition of the DGR and IMO publishes significant changes to its new Amendment.

December continues its slow slide into the official beginning of winter, with the solstice on the 21st—just a couple of days away. Stay warm and safe! The holidays are here, and no one wants to be ill or injured for them. Take the right steps to protect yourself and your fellow employees!  It was a busy week in the regulatory world, with both IATA and the IMO releasing documents related to their forthcoming new texts, so let’s jump right in.
