特朗普政府表示，根据两国之间的贸易协议，美国将从周二开始对日本汽车和汽车零部件实施较低的15%关税。美国海关指南确认，该税率将适用于2025年9月16日美国东部时间凌晨12:01之后从日本进口的“乘用车、轻型卡车和汽车零部件”。本月早些时候，特朗普总统签署了一项命令，将大多数日本产品的关税上限从27.5%降至15%，此前东京敦促华盛顿履行其削减汽车税的承诺，汽车是日本经济的关键支柱。汽车工业是日本对美国最大的出口部门，也是就业和工资的驱动力。作为更广泛协议的一部分，日本承诺建立一个5500亿美元的美国投资基金，尽管其融资问题仍然存在。商务部长霍华德·卢特尼克警告称，如果日本不支持特朗普的投资计划，可能会面临更高的进口税。

The U.S. will start implementing a lower 15% tariff on Japanese automobiles and auto parts from Tuesday, in line with a trade deal between the two nations, the Trump administration said. U.S. Customs guidance confirmed the rate will apply to “passenger vehicles and light trucks and automobile parts” from Japan entered for consumption after 12:01 a.m. EDT on September 16, 2025. Earlier this month, President Trump signed an order capping tariffs on most Japanese products at 15%, down from 27.5%, after Tokyo pressed Washington to honor its commitment to cut levies on autos, a key pillar of Japan’s economy. The auto industry is Japan’s largest export sector to the U.S. and a driver of jobs and wages. As part of the broader deal, Japan pledged to establish a USD 550 billion U.S. investment fund, though questions remain over its financing. Commerce Secretary Howard Lutnick warned Japan could face higher import taxes if it fails to back Trump’s investment plans.
