On May 28, 2026, the Office of the United States Trade Representative (USTR) published a notice in the Federal Register announcing a reduction in Section 232 tariff rates for certain products of Taiwan. 

According to the notice, certain automotive parts shall not be subject to additional 232 duties on aluminum, steel, copper, their derivatives, or wood; certain wood products of Taiwan are subject to "the ordinary customs duty treatment", which puts the rate at 15%; and certain civil aircraft components of Taiwan shall not be subject to additional 232 duties on aluminum, steel, copper, or their derivatives.

The reductions are the result of a Memorandum of Understanding (MOU) and "Agreement Between the American Institute in Taiwan and the Taipei Economic and Cultural Representative Office in the United States on Reciprocal Trade Between the United States of America and Taiwan" (ART) signed between the American Institute in Taiwan (AIT) and the Taipei Economic and Cultural Representative Office (TECRO) in the US.
