We're a US-based company who sells books and other media domestically. We've been contacted by a Canadian firm who would like us to fulfill a rather large order. I'm not 100% sure of the issues involved. Probably customs and taxation are the major ones. I'm guessing someone else here has done this before. What should I be aware of?
I could be wrong, but I have always understood the burden of customs and taxes to be on the buyer, not the seller.
