The steel and aluminum used in these products will be subject to a 50% duty rate.
The US Department of Commerce’s Bureau of Industry and Security has expanded the steel and aluminium tariffs to include 407 additional product categories covered by Section 232 sectoral tariffs on 19 August 2025.
As a result, the steel and aluminium content of these products will be subject to a duty rate of 50%.
The action covers wind turbines and their parts and components, mobile cranes, bulldozers and other heavy equipment, railcars, furniture, compressors and pumps, and hundreds of other products.
Under Secretary of Commerce for Industry and Security Jeffrey Kessler said, “Today’s action expands the reach of the steel and aluminium tariffs and shuts down avenues for circumvention – supporting the continued revitalisation of the American steel and aluminium industries.”
This is the latest in a series of historic steps by the Trump Administration to strengthen America’s steel and aluminium industry. In February, President Trump issued Proclamations 10895 and 10986, which eliminated numerous carve-outs from the Section 232 steel and aluminium tariffs and cracked down on tariff misclassification and duty evasion schemes.
These proclamations also directed Commerce, within 90 days, to establish a process for adding steel and aluminium derivative products to the Section 232 tariffs, which Commerce did in May. In June, President Trump issued Proclamation 10947, which increased the tariff rate for steel and aluminium from 25% to 50%, making the tariffs stronger than ever.
Under Commerce’s steel and aluminium product inclusion process, there are three annual windows for the public to submit product inclusion requests. The next window will open in September and will be announced in the Federal Register.
A complete list of the 407 product categories added today to the steel and aluminium tariffs is in the annexe to a Federal Register notice, available here.
Additional information regarding Commerce’s decisions on each of the product categories is available here.
Earlier, the Trump Administration had doubled the tariffs on US imports of steel, aluminium, and their derivatives from 25% to 50%, under the Section 232 tariffs, effective from 4 June 2024.
