It needs to go UPS or Fedex. Shipping ammo through USPS is a federal crime, and the postal inspectors won't look upon you kindly if you get caught. As Joe said, it needs an ORM-D sticker, which you can print from the internet and tape to the box. Other than that, not really that complicated.
Material marked "ORM-D" and shipped by surface transportation does not require hazardous shipping papers, simply an ORM-D and proper shipping name marking on the box.
This marking can either be in the form of a ORM-D sticker, or written by hand. If written by hand the letters "ORM-D" must be enclosed by a rectangle.
When transported by air, ORM-D shipments require an ORM-D-AIR marking and full hazardous shipping papers.
Can we ship ammunition through UPS? If so, what steps are required?
A.Ammunition must be shipped separately from packages that contain firearms. Only ammunition suitable for .50-caliber firearms or smaller is allowed. Also, when shipping, it’s important to print “ORM-D” on the package. Ammunition can be shipped only within the 48 contiguous states. Go to ups.com to view all UPS terms and conditions of service.
Something I found weird, I received some brand new unprimed .44Mag cases and a couple magazines for a rifle from a reputable company via Fed Ex. The package had the ORM-D labels on it. Just didn't understand why the markings were needed for what I ordered.
They weren't. You could stick ORM-D labels on everything you ship and it won't hurt a thing though. This is probably what the company you bought from does. In fact, it wouldn't be a half bad idea if you owned a company that sold ammo to have all of your boxes boxes PRINTED with ORM-D on them. Its a case of "It's better to have it and not need it than need it and not have it". If its on there, and you didn't need it, non issue. If its NOT on there, and you needed it, BIG issue.
The UPS Stores are independently owned and make their own rules, here in Prescott, AZ they will not handle ORM-D maybe others will. UPS may pick up, I don't know but I don't like paying for the service. Joe
