特朗普再调整对加拿大产品关税清单：胶合板等移出、阀门地毯等纳入，10月30日生效
华盛顿——白宫10月23日发布情况说明书称，特朗普总统当天依据1930年《关税法》第338条签署公告，进一步调整此前对部分加拿大产品加征关税的范围，产品增删将于10月30日生效。
具体调整是修订第11048号公告。该公告原为回应加拿大在汽车领域对美国商业的歧视而加征关税；此次修订将胶合板、部分纸制品、某些机械与制冷设备、某些包装箱盒等产品移出第338条关税范围，同时以某些阀门、地毯、废弃物产品及其他产品取而代之。
白宫称，这些第338条关税适用于所有被涵盖的商品，无论该商品是否符合《美国-墨西哥-加拿大协定》（USMCA）的原产地资格，并且是在1962年《贸易扩展法》第232条关税之外叠加征收。
背景方面，白宫称，加拿大今年夏天退出了一份与美国接近达成的贸易协议，并对约200亿美元的美国出口产品加征报复性关税；此后特朗普依据第338条签署了五份公告，禁止部分加拿大产品进口，并调整7月20日宣布的关税范围，该范围在9月8日曾再作修改。
白宫称，第338条授权总统在其认为公共利益需要时，暂停、撤销、补充或修订依据该条发布的公告；此次调整意在继续抵消加拿大歧视性做法对美国商业造成的负担、更好地服务公共利益，并保护美国农民、制造商与工人。白宫在说明书中称，特朗普已与全球近20个贸易伙伴达成公平对等的贸易安排，而过去一年半里只有中国与加拿大选择对美国的关税采取报复、而非谈判解决。

Trump Further Modifies Tariffs on Canadian Products Under Section 338, Changes Take Effect October 30
Washington — The White House said in a fact sheet on October 23 that President Donald J. Trump signed a proclamation that day under Section 338 of the Tariff Act of 1930 to further refine the scope of tariffs on certain Canadian products, with the product additions and removals taking effect on October 30, 2026.
The action modifies Proclamation 11048, which imposed additional duties to offset Canadian discrimination against U.S. commerce with respect to motor vehicles. Under the revision, certain products — such as plywood sheets, some paper products, certain machinery and refrigeration equipment, and certain packing crates and boxes — are removed from the scope of the Section 338 tariffs, and are replaced with certain valves, carpets, waste products, and others.
The White House said the Section 338 tariffs apply to all covered goods regardless of whether a good qualifies under the U.S.-Mexico-Canada Agreement (USMCA), and apply in addition to tariffs imposed under Section 232 of the Trade Expansion Act of 1962.
On the background, the White House said Canada walked away from a near-final trade deal with the United States this past summer and imposed new retaliatory tariffs on about $20 billion of U.S. exports, after which President Trump signed five proclamations under Section 338 to ban certain products from Canada and modify the scope of the tariffs announced on July 20, 2026; that scope was modified again on September 8, 2026.
The White House said Section 338 authorizes the President to suspend, revoke, supplement, or amend a proclamation under that section whenever he deems the public interest requires it, and that the latest refinement is intended to continue offsetting the burden on U.S. commerce from Canada's discriminatory measures while better serving the public interest and protecting American farmers, manufacturers, and workers. The fact sheet said President Trump has locked in fair and reciprocal trade deals with nearly twenty trading partners, while over the past year and a half only China and Canada have chosen to retaliate against U.S. tariffs rather than negotiate.
