The US government will formally announce reduced tariffs for non-semiconductor Section 232 products, to be applied retroactively starting from May 1, 2026, according to a notice published in the late hours of May 27 (US Eastern Time) in the Federal Register. In particular, the move will slash tariffs on Taiwan-made auto parts to a flat 15% from an average 26.71%, a sharp reduction that is expected to trigger a strong rally for Taiwan’s auto components makers.
