The Next Round of Tariffs May Exclude Aviation

Mere hours passed between the Supreme Court ruling that the IEEPA Chapter 99 tariffs were illegal, and the President issuing executive orders establishing the next set of tariff paradigms.

The White House issued an executive order calling for the establishment of new tariffs under Section 122 of the Trade Act of 1974 (19 U.S.C. 2132). The order demands that the government establish new tariffs setting a 10% duty rate on all foreign goods imported into the United States, starting tomorrow (February 24, 2026). The HTSUS code associated with this new tariff is expected to be 9903.03.01.

There is good news for industry: many aviation parts will be exempt from this new tariff. The exemption will apply to a list of HTSUS tariff codes that are typically associated with aircraft, engines, and their parts. The list is nearly 600 codes long, so it encompasses a significant number of aircraft parts classifications. Always check your HTSUS codes against this list for each import, to assess whether the additional duty applies to your import. The tariff provision that exempts aircraft parts from the new section 122 duty rate is expected to be 9903.03.05.

Section 122 permits the President to use tariffs to deal with large and serious United States balance-of-payments deficits. The United States has the world’s largest negative balance of payments; however, this provision only permits tariffs of up to 15% for up to 150 days. After that the tariffs can only be extended by an act of Congress.

Please note: this blog article is based on the Administration’s executive order. Tariff rules can be (and have been) changed between the executive order that announces them and the formal publication in the Federal Register. So please don’t make any legal moves until you have reviewed the final published language.

UPDATE: the 10% tariff has been established as predicted, and when into effect this morning (Feb 24, 2026).
