What is an Approved Manufacturer List (AML)?

Approved Manufacturer List (AML) Definition

An approved manufacturer list (AML) is a set of approved relationships between manufacturer parts and a company’s internally defined parts. Each relationship links a manufacturer’s part number to an internal part number and results from the R&D team’s identifying the third-party parts that can be used to satisfy the manufacturing requirements for the internal part. All approved AML parts for each internal part can share a single inventory bin.
