Federal Register

Definition

The Federal Register is the daily journal of the US federal government, published by the National Archives, that contains agency rules, proposed rules, notices, and presidential documents. For tariff policy, the Federal Register is the primary legal source: presidential proclamations, USTR Section 301 notices, Commerce Department AD/CVD determinations, and CBP regulatory changes are all published there. A tariff change does not have the force of law until it appears in the Federal Register. The Federal Register is available online at federalregister.gov, with full-text search and citable document IDs in the form YYYY-NNNNN.
