Certificate of Conformance vs. Certificate of Analysis

Material Certification Types

APP uses the following terminology to address certification of raw materials.

Certificate of Conformance (CofC):

A document supplied by the material manufacturer that specifies that the materials supplied meet the requirements specified (typically the manufacturer's own stated properties).  A CofC is typically not signed nor does it reference purchase order numbers (only lot numbers).  The value of a CofC is limited to traceability.

Non-Export Tooling

What is non-export tooling?

Non-export tooling is prototype tooling built in China.  Tooling will often be built to non-standard specifications using local Chinese steels.    It will have a stated tool life.  At the end of the tool life a new tool will have to be purchased in order to produce more parts.
