Top Original Equipment Manufacturer and Companies in the USA

An original equipment manufacturer, or an OEM, is a company that creates equipment or parts that may be marketed by another manufacturer. They supply replacement products or components for resale or incorporation into another product under the reseller’s brand name. OEMs are part of the growing trend of outsourcing.

The OEM economy of scale is driven by the demand for reducing production costs by major manufacturers. Since the introduction of the OEM in the computer software industry, procurement of those second market products or components as first-run products is made by repackaging with those value-added resellers (VAR). OEM outsourcing services contribute to assembly or other operation production processes on behalf of a client corporation. Another industry that often uses OEMs is the automotive industry. This article ranks the top suppliers of OEM automotive parts and OEM component and part contracting suppliers by their annual revenues.
