Hi all, I'm running an ammunition dealer's website and whenever we ship gunpowder or primers, UPS charges a $27 hazmat fee. I would like so when a customer checks out, this is listed in charges as a hazmat fee, but only for the items that need it. I've been searching for a while and can't find a way that doesn't tie in to the shipping module. I use UPS XML as my shipping module. Thanks! Gerald
