Lots of products. Its called Tariff Engineering https://en.wikipedia.org/wiki/Tariff_engineering.

Probably the best known example is Converse. "The felt lining on the bottom of the sneakers allows Converse to classify their product as slippers, so the company benefits from a much lower tariff rate." https://blogs.pugetsound.edu/econ/2019/02/18/tariff-engineer...
