For a product produced in the U.S. to be labeled Made in USA, or claimed to be of domestic origin without qualifications or limits on the claim, the product must be all or virtually all made in the U.S.

All or virtually all means that all significant parts and processing that go into the product must be of U.S. origin.  That means the product should contain no or negligible foreign content.

Therefore, for job creation purposes, those products labeled Made in USA cause the greatest number of American jobs to be created.  This is true because the labor to produce the product and the raw materials that go into the product are all made with American labor.
