For residents of the United States the duty free limit when returning is 800 dollars worth of stuff. I believe that’s every thirty days. You usually have to answer whether you exceed this limit in the declaration.
So you just go to Canada, buy the thing, unpack it from the packaging, and pretend like its just personal items. Just like a smartphone.
If tariffs become a big thing, this will definitely happen more, but it will also get a lot more scrutiny from customs as well.
AFIAK, border agents usually don’t ask if you bought your phone in the US or from outside, they shouldn’t ask about other personal electronics, right?
Stuff that you exported and reimported for personal or business use, but not for resale, is exempt from duty with no dollar limits. If you want documented proof that you are reimporting, you can register the stuff at a customs office in the United States before you leave.
I agree with you on this, but CBP is certainly within their legal rights to interrogate you on the origins of your personal electronics, and they can make a determination that your stuff is subject to duty if it’s over the limit and they don’t believe you are reimporting.
