API 20E/F Bolting supplier 1

Interpretation 6A-2019-02:

"Response: No. The requirement does not mean that only a certified [licensed] supplier of 20A product can be used. It simply means that the product must mean (sic) the requirements of 20A and that product can come from any supplier. It is the responsibility of the manufacturer of 6A equipment to be able to demonstrate that the material conforms to API 20A, when applicable. How that is done, is up to the manufacturer.
NOTED This applies to 20E and 20F requirements for applicable products as well."

As Steve says, no need to buy from a monogrammed supplier, although much easier if you can.

The simplest way to buy from a non-monogrammed supplier is to audit them against API 20E for example so you can demonstrate they meet the requirements if they do?

Thank you for your reply.
I agree that the easier way is to buy from a monogrammed supplier but especially for small valves is necessary reduce the impact on product cost generated form API 20E bolting.
I believe that the same bolting with same quality level from a non monogrammed supplier could be a solution to minimaze the impact.
