Section 232 Investigations of Copper, Timber, and Lumber Get April 1 Comment Deadline

The Bureau of Industry and Security is accepting comments by Apri1 1 on two Section 232 investigations recently initiated to determine the national security effects of imports of copper, lumber, and timber. These investigations could result in new tariffs, export controls, or other remedial measures.

The Section 232 investigation of copper covers copper in all forms, including raw mined copper, copper concentrates, refined copper, copper alloys, scrap copper, and derivative products. The investigation of timber and lumber covers those goods as well as their derivative products (e.g., paper products, furniture, and cabinetry).

These investigations will assess – and comments are therefore being solicited with respect to – factors such as (1) current and projected demand and the extent to which it can be met domestically, (2) the role of foreign supply chains, particularly from major exporters, in meeting demand, (3) the impact of foreign government subsidies, overcapacity, and predatory trade practices, and (4) the feasibility of increasing domestic capacity to reduce import reliance.

BIS reports in these investigations are due within 270 days (i.e., by late fall 2025) but officials have suggested the reports could be submitted sooner. Each report will include the findings of the investigation; recommendations on actions to mitigate any identified threats, including potential tariffs, export controls, or incentives to increase domestic production; and policy options for strengthening the U.S. supply chain.
