特朗普政府部分取消加拿大关税，缓解中期选举前贸易压力

特朗普政府宣布对加拿大部分商品的关税进行调整12。此次关税调整将于10月30日生效，涉及胶合板、纸制品、某些机械和制冷设备等产品的关税降低2。同时，政府也将对地毯、某些阀门和废旧产品征收新税2。

这一举措发生在美国中期选举前两周2。缅因州共和党候选人苏珊·柯林斯向特朗普团队施压，要求缓解关税对当地的影响。柯林斯表示："我们许多农民和种植者依赖加拿大的专门设备、包装材料和其他产品，这些产品要么无法从美国供应商获得，要么替代品成本高昂"2。白宫称此举目标是抵消"对美国商业的负担，同时更好地服务公众利益"2。

此次关税调整是特朗普去年回归白宫后与加拿大贸易纠纷升级的最新进展2。今年8月谈判破裂后，特朗普宣布对部分加拿大商品征收50%关税，加拿大总理马克·卡尼随后宣布了报复性关税措施2。

The Trump administration has announced a partial rollback of tariffs on Canadian goods, set to take effect on October 30.2 The adjustment will reduce duties on plywood, paper products, certain machinery, and refrigeration equipment, while simultaneously imposing new tariffs on carpets, specific valves, and scrap materials.2

According to Senator Susan Collins, the move targets relief for American agricultural producers and businesses affected by the trade dispute.12 Collins stated that "many of our farmers and growers depend on specialized equipment, packaging materials, and other products from Canada that either cannot be obtained from U.S. suppliers or have prohibitively expensive alternatives."2 The tariff adjustment comes two weeks before the November midterm elections, with Collins having pressured the Trump administration to ease the burden on Maine's agricultural sector and local enterprises.2

The action follows a months-long escalation in U.S.-Canada trade tensions.2 After negotiations broke down in August, the Trump administration announced a 50 percent tariff on select Canadian products.2 In response, Canadian Prime Minister Mark Carney announced retaliatory tariffs.2 The White House characterized the current adjustment as aimed at "offsetting burdens on American business while better serving the public interest."2
