I work for UPS and there is no company policy or paper work associated with large quantities of ammo being shipped, other than the ORM-D stuff. This is manditory by the gov't on all Hazardous materials. As a matter of fact, ORM-D isn't regulated as much as other hazmat stuff. No paper work is required, other than a sticker on the box saying ORM-D, which is designated as a consumer commodity of potentially hazardous materials.--like lighters, paint, ammo, etc...
If anyone associated with UPS notifies any gov't body, it is of their own convictions, not the company or the gov't. I would say, if my driver or his manager is doing this, call a corporate complaint on them. This will stop. End of story. 1-800-PICK-UPS.
If the credit card companies are doing this, pay with cash, if your that concerned.
Good luck and keep the ammo comming...I am one driver who looks forward to those heavy boxes being delivered!!!
