US Tariffs on Fabric Imports Question

[MacCathmhaoil]

I always try to have international shipments delivered via Canada Post, more often than not there is no duty/tax added on and when there is there are no additional fees such as those associated with the courier companies. Now I realize the practices of Canada Post are not those of the U.S. Postal Service but even if they do charge duty there should be no brokerage or handling fees added.
