UN Specification Markings

Packaging specification markings are those that identify the design or specification of a packaging, regardless of its use for a particular shipment. Packages that require UN specification markings are subject to performance tests to ensure that the package is properly designed to adequately contain its contents under normal conditions of transport. The type and severity of the performance tests are dependent on the degree of danger of the intended contents.

These markings are usually applied by the manufacturer or the authorized testing institute but are ultimately the responsibility of the shipper. Packaging specification markings are not required for limited quantity packages.
