I have been fortunate with my business. I know the exact tariff codes for my products and can check the box acknowledging they were made/mfg in the USA. That helps my shipments sail through customs. My guess is that JoAnns products are 99.9% NOT made in the USA (or North America for NAFTA) making the listing of multiple tariff codes and calculating appropriate taxes a nightmare. I would not want to do it but it could be a new business idea to design a software program that would calculate this, prepare the forms, and pay the tarrifs.
