"Not entirely true. Hazmat fees are "allowed" not dictated. What DOT does dictate is the extra record keeping and storage requirements that shippers must use when transporting "hazardous material". Shippers are allowed to offset the cost of that extra requirement by charging a fee - not that it really costs that much for extra record keeping and handling for a box of primers or powder. I too wish they would hurry up and get on with the removal of primers from the list."
You are splitting hairs. I manufacture explosives that have to be classified by DOT, I know how the system works.
