PDX is the Product Data eXchange standard for the e-supply chain. Product Data eXchange is a multi-part standard, represented by the IPC 2570 series of specifications. The Product Data eXchange standardization effort is focused on the problem of communicating product content information between Original Equipment Manufacturers, Electronics Manufacturing Services providers and component suppliers. The standard is based on XML because this provides a simple yet powerful and flexible way to encode structured data into a format that is both human and machine-readable.

The Product Data eXchange standard provides a way to describe product content (Bill of Materials (BOM), Approved Manufacturer Lists (AML), Drawings, etc.), Engineering Change Requests (ECR), Engineering Change Orders (ECO) and Deviations in an eXtensible Markup Language (XML) format. This standard will enable dramatic efficiency improvements throughout the supply chain since partners will have a way to exchange product content and changes in a common language.
