Counterfeit parts – Parts that are produced with the intent of misleading the consumer.

Production, sale of and use are all subject to civil and criminal penalties for violation of patent and trademark laws. They are also subject to prosecution by the U.S. Department of Justice for deceptive trade practices.

White box – Unbranded products produced in various countries with part numbers for several competitive brands. Typically high-volume parts purchased in bulk; usually sold to consumer on repair invoices at branded product prices and represented on invoices as those brands.

Gray market products – Products produced by contract or joint venture manufacturers for OEM or branded product suppliers. Gray Market products are typically intentional over-runs on production, or in many cases those that were rejected for various quality issues. These products are sold, referencing the brand and stating that they have excess inventory. Primary concern is the sale of quality rejected products as good product.

Genuine OEM – Products designed for, tested, validated and approved by vehicle manufacturers for assembly line use or aftermarket sale.
