Paying taxes/duty on used goods purchased in Canada

Riffer makes a good point about preparing for the worst because it is like a roller coaster, once you go over the top, you are no longer in control.  Best case is probably that you pay brokerage only, which I get charged for even small purchases from Partsconnexion, unless they are shipped by postal service. Some years ago, I believe it was around a hundred bucks or so for a SF preamp.  The NAFTA comments are valid but I would add, from experience, they are picky about the documentation being on a specific form and executed by the manufacturer, otherwise it may do you no good that they were manufactured in Canada.  One scenairo I have no experience with is shipping by a commercial carrier (I.e., a trucking company), although I would expect similar issues.

Looks like under $50 based on the link provided by Riffer. No duties, just this brokerage fee it looks like.

The seller/shipper will most likely pay at UPS....? Right?

IME, you will probably get a bill for brokerage about a week or so after delivery,. I have never seen the seller pay for this.

I bought a Rega table, made in England, and the seller shipped to me unknowing of the fee.   When UPS delivered it I owed $45.   Not sure how it was assessed but it seems Fedex and UPS charge the fee.  With the CAD to USD exchange rate good deals are to be had from our northern neighbors.
