Understanding Overpack Requirements for Air Transport (IATA DGR)

Learn how to prepare, mark, and document overpacks correctly under IATA regulations in under 1 hour.

What is an overpack?
An overpack is an enclosure used by a single shipper to contain one or more packages. It’s used for easier handling or to consolidate multiple packages into one unit. Common examples include shrink-wrapped pallets or boxes containing smaller packages.

Do overpacks need to be marked and labeled?
Yes. Overpacks must display all markings and labels of the packages inside, unless these are clearly visible from the outside. In addition, the word “OVERPACK” must be clearly marked if required.

Are airlines allowed to break down an overpack?
No. Overpacks must remain sealed and intact. Airlines are not permitted to dismantle or open an overpack.
