The FTC enforces “Made in the USA” claims under its deceptive advertising laws. They apply to products sold anywhere in the United States. The rule is that "all or virtually all" of the parts and processing must be of U.S. origin. The product should contain no — or negligible — foreign content. Claiming “Made in the USA” for foreign lifters machined or assembled in the U.S. would certainly violate FTC regulations.
