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,

Any customs forms will be completed by the sender. If the item is light enough it should be sent through Canada Post. More than likely the item will enter USA with no problem. If the item is made in Canada there should be no duty, if not you COULD be accessed duty but probably not. Country of origin is filled in on the customs form.
I frequently buy and sell overseas and have paid duty and fees only once courtesy of UPS.
