The parent comment was a confusing statement. They were saying that buying a used car or goods from a second-hand store does not go through the tariff process because the produce is already here.

There was a loophole in the past where you could take delivery of a car in a foreign country, drive it for a while, and then go through the process of importing it as if you were moving back to the United States. I don't know if the new tariffs honor that loophole or not.
