I think safety and prevention were the intent of the federal regulations, but like everything the government does it is of little avail, goes way overboard, and accomplishes little. The powder and primers I get on a regular basis from several suppliers are packaged no different or any safer than the non-"hazardous" materials. At most, their is a label or printing on the box identifying the contents but there is no further attempt at safety. It basically is an opportunity for shippers like UPS and FedEx to charge 100 times more than the paperwork actually costs them and to force their political beliefs on others. If I understand the regulations, the hazmat fees go to the shippers, not the sellers.
I also believe that at the outset of hazmat mania, the ownership of UPS was anti-gun and engineered the fees to "punish" people into not buying powder and primers. Labels or not, the delivery persons throw the boxes from one end of the van to the other and seem to be totally oblivious to what the contents are. I've never heard any horror stories of brown vans being burned to the ground or blown up because of smokeless powder or primers igniting. Imagine that the "safety" regulations allow and, actually, encourage putting primers and powder in the same package.
