The steel, aluminum and copper tariff instead is 10% in place of the regular duty where this applies: “For derivative articles provided for in subdivisions (c)(ii), (vi), and (ix), at least 85 percent of the aluminum content of the article must be composed of aluminum that was smelted and cast in the United States. For derivative articles provided for in subdivisions (c)(iv), (vii), (x) and (xi), at least 85 percent of the steel content of the article must be composed of steel that was melted and poured in the United States. For articles provided for in subdivision (c)(viii), at least 85 percent of the copper content of the article must be composed of copper that was smelt and cast in the United States. These requirements are cumulative such that a derivative article in more than one subdivision must satisfy each requirement” (HTS 9903.82.07).
