Purchase Order Notes or Quality Notes that define part requirements that affect the manufacturing, process, packaging, performance, or traceability of the Caddock product will only be accepted by Caddock when these additional requirements are specified in the Customer Specification Control Drawing (SCD).

Assistance in developing the Customer Specification Control Drawing (SCD):
Caddock Application Engineering will work together with the Industrial Customer Engineering or the Military Customer Engineering to generate a mutually agreeable SCD. In this way, all of the User requirements that impact the procurement of the product, the manufacturing of the product, the quality conformance inspection requirements, the documentation of the product, and the shipment of the product will be fully and agreeably defined.

The SCD for "Support Category1" products, when necessary, must specify:
