On September 16, 2026, Taiwan's Executive Yuan announced the 18th wave of tariff and business tax cuts on selected agricultural imports, extending relief through March 31, 2027. The measures maintain full waivers on the business tax for soybeans, wheat, and corn, a full waiver on the wheat import tariff, and 50 percent tariff reductions on butter, baking-use milk powder, anhydrous milk fat, and beef. The extension responds to renewed Middle East volatility, with Brent crude reaching $130.54 per barrel on September 15, up more than 80 percent since late February 2026.
