I have a small stockpile of butane canisters for emergency (12 canisters). I'm moving, and the movers won't take them. I just discovered UPS won't take them from individuals. (The hazmat specialist on the phone didn't tell me about this. She just made sure the material is shippable. She might have assumed that I have a hazmat account with them and I have the certification needed to ship hazmat. She told me I could ship it. So I was surprised to learn I actually couldn't when I brought the box to the UPS hub.) So how can I ship butane canisters?
