Recital 6

6. Section 338 authorizes the President, if he determines it will serve the public interest, to offset any burden or disadvantage placed on the commerce of the United States by an unequal imposition or discrimination by a foreign country by specifying and declaring additional duties not to exceed 50 percent ad valorem (or its equivalent) and not to take effect earlier than 30 days after the President’s proclamation finding that a foreign country imposes an unreasonable charge, exaction, regulation, or limitation that is not equally enforced on the like articles of every foreign country, or discriminates in fact against U.S. commerce in a way that places the commerce of the United States at a disadvantage compared to the commerce of any foreign country. Section 338 also authorizes the President to suspend, revoke, supplement, or amend any proclamation under section 338 whenever the President deems that the public interests require such action.
