Commerce Department weighing more steel and aluminum tariffs

The agency will publish a Federal Register notice Wednesday officially opening a new comment period on the 50 percent duties and their possible expansion.

More downstream steel and aluminum products could soon face higher U.S. tariffs.

The Commerce Department’s Bureau of Industry and Security announced in a federal notice set for publication Wednesday that it is opening a comment period as it weighs expanding the list of goods made from steel and aluminum that face a 50 percent tariff. President Donald Trump first levied a 25 percent duty on certain steel and aluminum imports during his first term, which he expanded to all countries shortly after returning to the White House. He then doubled the tariff at the beginning of June.

The comment period began Sept. 15 and will run to Sept. 29, per the Commerce Department’s notice.

The notice comes about a month after Commerce added more than 400 product lines to the Harmonized Tariff Schedule, which the U.S. uses to classify imports and assess tariffs, targeting auto parts, plastics, chemicals and other products derived from steel and aluminum.
