Overpacks

An “overpack” could be in the form of a larger container or shrink-wrapping around multiple packages.

All marking and labelling on dangerous goods packages contained in an “overpack” (see terminology) must be clearly visible or reproduced on the overpack. These markings would include Limited Quantity or Salvage Packaging (if applicable).

If consignment consists of multiple overpacks, an identification marking must be shown on the outside along with the total quantity of each individual substance contained within the consignment.

This information is also to be shown on the Shipper's Declaration form.
