How Do I Request a Certificate of Conformance (COC)?
PNW Sanitary can provide a Certificate of Conformance (COC) for stainless steel fittings, tubing, and other sanitary components upon request. A COC verifies that a product meets the published specifications, material requirements, and applicable sanitary standards.
All COCs are issued on official PNW Sanitary letterhead and delivered electronically as PDF files.
To request a COC, please email:

What a COC Includes
A PNW Sanitary Certificate of Conformance typically includes:
- Product description and SKU
- Applicable specifications (such as ASTM material grade)
- Confirmation of alloy (304 or 316L)
- Sanitary / 3-A conformity statement (if applicable)
- Internal QC verification and approval
Important: A COC does not include chemical composition or heat/lot chemistry. If you need full material chemistry or heat/lot traceability, please request an MTR instead.
