What do I need for customs if purchased in Canada & ship to US?


If I buy a component from someone in Canada and want them to ship it to me in the US, what should I have the seller do to get it through customs?  I'll probably tell them to use the Canadian Mail to USPS.  
Are there forms to be filled out & maybe attached to the outside of the box?  A copy of the receipt attached to the box?   Something else.  My total purchase amount would probably be $1,000 or less.
How expensive are the US customs rates?
Thanks,

I had a bad experience using UPS to ship from Canada to the US. They billed me for customs, and imposed a brokerage service charge, for an item that should not have been subject to customs. It was for a Triplanar tonearm that I already owned. I sent it to the builder of my turntable so that he could drill the holes for mounting of the arm. UPS billed me for the return shipping of the tonearm, but not for the turntable. Weird. Since then, I insist on using Canada Post for items shipped from Canada. No problems with them.
