UN1A1 Packaging


We sell several different steel drums and pails with a UN1A1 designation.  The explanation for this is as follows:

  • UN = United Nations
  • 1 = Drum
  • A= Steel
  • 1 = Tight Head

We will list all the UN1A1 steel drums and pails we currently stock in this article, however, they all differ in the rest of their UN designation.  As an example, some are UN1A1/Y  (Packing Group II and III) rated and some are UN1A1/X rated (Packing Group I, II or III).  We will group them by X or Y rating below.  Also, the following numbers after the X or Y rating, would be maximum specific gravity the drum has been tested to hold for 5 minutes and then maximum hydrostatic pressure the container has been tested to hold for 5 minutes.

Although these drums are UN rated, they may also be used for non-hazardous product.
