For those familiar with the nomenclature of United Nations (UN) markings, it is a system that does offer a significant amount of information about a packaging. However, even as a longtime DG packaging manufacturer, I still have a hard time grasping all the meanings of the various marks. To help everyone with this knowledge, we have created a tool to help explain the regulatory requirement and sequence of characters. Interpreting UN Markings is located in the Resources tab of Skolnik.com and was created to identify and explain the unique significance of each UN marking, each character and the required sequence for markings on an Open Head Steel Drum for Liquids, and Open Head Steel Drum for Solids, a Closed Head Steel Drum for Liquids and a Closed Head Nitric (Acid) Stainless Steel Drum. In accordance with CFR178.503(a) plus 178.153(b) for the Nitric Drum, each marking is identified by the specific CFR reference with direct links to the actual CRF regulatory requirement. The illustrations also include the location(s) in which the marking must be applied. It is also important to note that the specific sequence is not alterable. The marking can be broken into several lines but the sequence must be as indicated. Click here to see the 4 marking examples.
