UN Approved Packaging Basics – How To Read The Markings

UN approved packaging is a destination for packaging that has been built, tested, and certified to carry liquid or solid dangerous materials. This is a unified means to ensure dangerous materials are transported safely. While the term “dangerous materials” may be misinterpreted as harmful, in the United States, it is simply a method DOT has for defining safe and secure shipment for certain chemicals listed in 49CFR (Code of Federal Regulations – Transportation).

UN Markings

Each UN approved package must have a permanent UN marking on the package.

All UN markings must have an approved UN mark followed by a string of code. These codes identify what each of these UN approved packages is approved to carry, materials used to construct the package, maximum gross mass or specific gravity, year, and location of manufacture.
