U.S. Quietly Tweaks Tariffs in Fresh Taiwan Security Pact
Published Date: 5/28/2026
Notice
Summary
The U.S. is updating tariffs as part of a new trade and security deal with Taiwan, following agreements signed in early 2026. These changes affect businesses trading goods between the U.S. and Taiwan by adjusting certain tariffs to support fairer trade and national security. The updates start now, but some parts of the deal will kick in later once fully approved.
Analyzed Economic Effects
5 provisions identified: 4 benefits, 1 costs, 0 mixed.
Taiwan Credit Guarantees and $250B Investment Pledge
Under the MOU, Taiwan will provide credit guarantees to support corporate credit lines of up to $250 billion to facilitate investment, and Taiwanese semiconductor and technology enterprises committed to make direct investments totaling $250 billion in the United States to build and expand advanced semiconductor, energy, and artificial intelligence production capacity.
Auto‑Parts Tariff Cap for Taiwan
If you import automobile parts that are products of Taiwan, Section 232 additional tariffs on those parts are limited so the total ad valorem duty will not exceed 15%. For parts with an existing HTSUS Column 1 duty rate of 15% or more, no Section 232 duty will apply; for parts with a Column 1 rate under 15%, the sum of the Column 1 rate and any Section 232 ad valorem tariff will equal 15%. These rules apply to goods entered on or after May 1, 2026, and special foreign‑trade‑zone admission rules apply to parts admitted to FTZs on or after that date.
Wood Products Duty Fixed at 15%
If you import timber, lumber, or certain wood derivative products of Taiwan, those goods are placed under HTSUS heading 9903.76.24 with a 15% duty rate. The 15% duty under heading 9903.76.24 will be collected in lieu of any special free‑trade agreement or preference program rate, and this treatment applies to entries on or after May 1, 2026.
Aircraft Components Exempted from Metal Tariffs
For civil aircraft components that are products of Taiwan, the United States will not apply the derivative Section 232 steel, aluminum, and copper additional duties. The exemption applies to the listed HTSUS subheadings and is effective for goods entered on or after May 1, 2026.
Expected Boost for U.S. Steel, Copper, Wood, and Auto Supply
The notice states that recent and future steps under the MOU and ART will have a direct and positive impact on U.S. production and will raise demand for U.S.-produced steel, aluminum, copper, automobile parts, and wood products. The ART, once implemented, is said to create conditions for expanded U.S. export opportunities for those sectors.
