美国海关确认多退少补！对日本产品征15%关税这样操作

Core Viewpoint - The US-Japan Trade Agreement officially took effect on September 15, 2025, with the US imposing a 15% baseline tariff on nearly all Japanese imports, impacting various sectors including automobiles and electronics [3][4]. Summary by Sections Tariff Adjustments - The current US tariff rule states that if the existing tariff is below 15%, it will be adjusted to 15%. If it is equal to or above 15%, it will remain at 15% [3]. - The tariff on Japanese automobiles has been reduced to 15% as of September 16, 2025 [3]. Specific Product Tariffs - For electronic products, the original tariff rate of 0-5% has been increased to 15%. Aerospace products will no longer be subject to "reciprocal tariffs," and tariffs on steel, aluminum, and copper have been standardized to 15% [4]. - However, steel and aluminum products will continue to be subject to a 50% tariff under Section 232 [5]. Impact on Trade - Japan's exports to the US have seen a continuous decline for three months, with the rate of decline increasing, attributed to the US government's tariff policies [5]. - The delay in implementing the new tax rate is estimated to increase the burden on Japanese automakers by 100 billion yen, approximately 3 billion yen per day [8]. Refund Mechanism - The US Customs and Border Protection (CBP) has confirmed that importers can receive refunds for tariffs paid that exceed 15% for goods imported after August 7, 2025 [6][10]. - Importers can submit a post-summary correction application for estimated duties not yet liquidated, and for cleared imports, they can protest under US Code Title 19, Section 1514 for refunds [9][10].
