The Guides in this part apply to the manufacture, sale, distribution, marketing and advertising (including advertising in electronic format, such as on the Internet) of parts that are not new, and assemblies containing such parts, that were designed for use in automobiles, trucks, motorcycles, tractors, or similar self-propelled vehicles, regardless of whether such parts or assemblies have been cleaned, repaired, reconstructed, or reworked in any other way (industry product or product). Industry products include, but are not limited to, airbags, alternators and generators, anti-lock brake systems, brake cylinders, carburetors, catalytic converters, differentials, engines, fuel injectors, hybrid drive systems and hybrid batteries, navigation and audio systems, power steering pumps, power window motors, rack and pinion units, starters, steering gears, superchargers and turbochargers, tires, transmissions and transaxles, and water pumps.

These guides set forth the Federal Trade Commission's current views about the manufacture, sale, distribution, and advertising of industry products. The guides help businesses avoid making claims that are unfair or deceptive under Section 5 of the FTC Act, 15 U.S.C. 45. They do not confer any rights on any person and do not operate to bind the FTC or the public. The Commission, however, can take action under the FTC Act if a business makes a claim inconsistent with the guides. In any such enforcement action, the Commission must prove that the challenged act or practice is unfair or deceptive in violation of Section 5 of the FTC Act.
