You won't get a list - you need to provide him with a list of what you want to bring - and he'll send back a message with the rate for each item.
I have found that no matter what the "official" rates are, but the time I bring in something I want, with shipping, duties, brokerage fees etc. I end up between 50 - 100% of the new value in the States. Needless to say, I only import things I really want.
