As part of the systematic review of all Commission rules, on January 30, 2012, the Commission initiated its periodic review of the Wool Rules by publishing a notice seeking public comments on the effectiveness and impact of the rules. 77 FR 4498. On September 16, 2013, the Commission announced it was issuing an NPRM proposing changes designed to clarify and update the rules, to make them more flexible, and to align them with the Commission's proposed amendments to the Textile Rules. 78 FR 57808. The comment period was initially set to close on November 25, 2013. The comment period later extended closed on December 3, 2013. On June 4, 2014, the Commission amended the Wool Rules to conform to the 2006 amendments to the Wool Suit Fabric Labeling Fairness and International Standards Conforming Act and the amended Textile Rules. 79 FR 32157. The changes included incorporating the laws new definitions for cashmere and very fine wools clarifying descriptions of products containing virgin or new wool and allowing certain hang-tags disclosing fiber trademarks and performance even if they do not disclose the products full fiber content. The amended rules were effective on July 7, 2014.

The Wool Products Labeling Act of 1939 (Wool Act) requires covered wool products to be marked with: (1) the generic names and percentages by weight of the constituent fibers present in the wool product; (2) the name under which the manufacturer or another responsible U.S. company does business, or in lieu thereof, the registered identification number (RN) of such a company; and (3) the name of the country where the wool product was processed or manufactured. Pursuant to section 6(a) of the Wool Act, "The Commission is authorized and directed to make rules and regulations for the manner and form of disclosing information required by this Act ... and to make such further rules and regulations under and in pursuance of the terms of this Act as may be necessary and proper for administration and enforcement." These implementing rules and regulations are set forth at 16 CFR 300.
