Section 232 Investigations

A Section 232 investigation is conducted under the authority of the Trade Expansion Act of 1962, as amended. The purpose of the investigation is to determine the effect of imports on the national security. Investigations may be initiated based on an application from an interested party, a request from the head of any department or agency, or may be self-initiated by the Secretary of Commerce.

The Secretary’s report to the President, prepared within 270 days of initiation, focuses on whether the importation of the article in question is in such quantities or under such circumstances as to threaten to impair the national security. The President can concur or not with the Secretary’s recommendations, and take action to “adjust the imports of an article and its derivatives” or other non-trade related actions as deemed necessary.
