The steel, aluminum and copper tariff doesn't apply to “Articles provided for in subdivision (c) of U.S. note 16 to this subchapter that do not contain any aluminum, steel, or copper” (HTS 9903.82.01).

No forced-labor tariff here: products covered by the steel, aluminum and copper tariff (HTS 9903.82.02) are exempt from it.

The steel, aluminum and copper tariff instead adds 200% where this applies: “where any amount of primary aluminum used in the manufacture of the aluminum articles is smelted in Russia, or where the aluminum articles are cast in Russia” (HTS 9903.85.67).
