The Federal Trade Commission (FTC or Commission) amends the Rules and Regulations under the Textile Fiber Products Identification Act (Textile Rules) to revise the form for Application for a Registered Identification Number ("RN") in order to facilitate receiving applications electronically; incorporate by reference the generic fiber names and definitions for manufactured fibers in International Organization for Standardization standard ISO 2076: 1999(E), "Textiles--Man-mad fibres--Generic names;" clarify origin labeling requirements for products made in the U.S. and assembled or finished abroad or products manufactured abroad of U.S. fabric; and correct a typographical error. The Commission amends the Rules and Regulations under the Wool Products Labeling Act of 1939 (Wool Rules) to clarify that only one RN will be granted to a qualifying firm; and clarify the origin labeling requirements for products made in the U.S. and assembled or finished abroad or products manufactured abroad of U.S. fabric. Because these amendments are technical and non-substantive, the Commission finds that notice and comment are not required. For this reason, the requirements of the Regulatory Flexibility Act also do not apply.
