@tsarstepan,
Really?
Well I'm basing it on common sense, because the global rules are somewhat ambiguous as to what is American and what is not, and it is ambiguous in order for marketing firms to label whatever they want, and although FTC has rules, there are a lot of loopholes a company can find to call a product made in America, without actually it being made in America.
And are you really equating "Assembled in America" with "Made in America."
So I can start a car company, import all the parts from Japan to America, and then assemble it in America, and then call it "Made in America." Are you sure that I am going to get away with that with the Federal Trade Commission?
Because as a customer, what I call, that which I just explained above is guile or a trickery.
