16 CFR Part 20
Rule Summary

The Guides prohibit misrepresentations that a part is new or about the condition, extent of previous use, reconstruction, or repair of a part. Previously used parts must be clearly and conspicuously identified as such in advertising and packaging, and, if the part appears new, on the part itself. The Guides describe the treatment a part must receive before it can be described as "rebuilt" or "remanufactured," and limit use of the term "factory rebuilt" to parts built "at a factory generally engaged in the rebuilding of such products." The Guides also prohibit misrepresenting a part rebuilder's identity.
