What happened to NAFTA? I never had a problem bringing HDs from Canada to the US?
I was still under the impression that Canadian and US goods traveled freely?
The only problems I've had was bringing Ducatis to the US. Those were taxed as they were made in Italy and weren't taxed by the US yet.
I think you may be confusing duties and taxes. Canada charges at least our insane sales taxes (15%). Goods that are subject to duties (most imported stuff; I think a US-made guitar may be exempt; I'd have to check!) get charged anywhere from another 5-20%.
