3. Invalidated IEEPA Tariffs
On February 20, 2026, the U.S. Supreme Court ruled that the large-scale global tariffs (including the 20% general tariff on Chinese goods) imposed by the Trump administration under the International Emergency Economic Powers Act (IEEPA) were unlawful ab initio and fully invalidated. This includes tariff codes such as 9903.01.224 and 9903.01.63, which are no longer enforced.
4. Section 122 Temporary Tariffs (10% – Exempted)
Following the Supreme Court ruling, the White House implemented new tariffs under Section 122 of the Trade Act of 1974 (Balance of Payments Provisions), adding tariff codes 9903.03.01–9903.03.11 to Chapter 99:
• 9903.03.01: Imposes a 10% temporary tariff on all imported goods worldwide, except for exempted items.
• 9903.03.03: Includes optical modules under 8517.62.00.90 in the exemption list. Importers may declare 9903.03.03 to be exempt from the 10% tariff specified in 9903.03.01.
