Having dealt with A LOT of Hazmat shipping recently, let me try and clarify a little, hopefully, maybe. The court case ruling won by TRA and NAR succeeded in removing AP-composite propellants from the *ATF* List of Explosives. The issue currently at hand is the *DOT* classification of propellants for commercial shipment. DOT has a testable standard (49 CFR § 172 is the standard, DOD TB 700-2 are the tests) which governs the classification of various compounds. Unfortunately for us, AP composite propellant ends up as a 1.3 explosive in those tests. It's a pain to ship 1.3, so several vendors applied for a special permit to allow for reloads to be shipped as 1.4, which is easier to mail via UPS/FedEx; if you've ever had high power motors shipped to you, they came in a box with an orange 1.4 EXPLOSIVE sticker on the side and a copy of the special permit that allowed the shipment to happen (http://phmsa.dot.gov/staticfiles/PHMSA/SPA_App/OfferDocuments/SP10996_2006080754.pdf). You can see the list of people authorized to ship under this particular exemption by typing 10996 into the search box at http://phmsa.dot.gov/hazmat/regs/sp-a/special-permits/search. A similar process was undertaken to allow model rocket motors to be shipped as 4.1 Flammable Solids (http://phmsa.dot.gov/staticfiles/PHMSA/SPA_App/OfferDocuments/SP7887_2006080041.pdf). Shipping flammable solids isn't that much different from shipping 1.4 Explosives, so in practice, this didn't make that much of a change. The only major is that the orange "EXPLOSIVE" sticker is replaced with a red and white "FLAMMABLE SOLID" one; packaging (UN 4G) and shipping (Hazmat) requirements remain the same. So what's the dustup? It's words. It's much easier for a teacher or a camp leader to receive a box that says "Flammable Solid" on the side than one that says "Explosive". Storage-wise, shipment-wise, and handling-wise, there is no difference. Explosives and flammable solids both require the same boxes and the same Hazmat shipping fees, so to you (the end consumer), the difference is nil. To DOT, propellant *is* an explosive. And they have tests to prove it.
