Uhh... Whether you're a citizen isn't a factor. There's no federal sales tax, although these tariffs act as an import tax that will increase the wholesale costs. And state sales taxes don't apply to imports or wholesale transactions, they are retail tax (or also often a use tax if a sales tax wasn't previously imposed).

VAT is not only a retail sales tax, it'll apply anytime the widget is somehow modified (value is added).
