I don't know about the trade issues either - but looking at Powder Valley's inventory, it appears that IMR, Alliant, Accurate and all of them must have the same issues :
Powder Valley, Inc.
I hate that HAZMAT fee, so I try to buy locally. One dealer nearby will order any powder for me, using my credit card to hold it, and when it comes in will call me. And, his prices are fair.
BTW, Hodgon is made in Australia, Canada, Mexico and probably a few other locations.
