The label (required 2014) was on the box of a recently UPS delivered case of ammunition.
A visit to several talk boards finds that some receiving clerks are requiring private shippers (you and me) to write the words Ammunition or Hazardous materials or some other such wording on the box.
This is not required. If requested, ask to speak to a supervisor.
Diamond Labels Will Replace ORM-D Labels on Ammo Shipments
The Dept. of Transportation (DOT) is phasing out the current ORM-D ammo labels, replacing them with a larger striped diamond label that does not mention “Small Arms Cartridges”. This change is designed to harmonize U.S. shipping rules with United Nations standards.
“The good news is the new label doesn’t have any indicator that the package contains ammunition. The bad news is the new label is gigantic compared to the old ORM-D label. You are required to use one of the larger labels on one side of any package containing ammunition. If the package is too small for one of the larger labels then you are permitted to use one of the smaller labels instead. Because of the size requirement in the regulations, you only get two of each label on standard piece of printer paper.”
