Peter, a customer raised the question during a recent audit “why do my customers demand so many certificates of conformance “CoC”?
So, the first question is what is a CoC? According to Google a “CoC”, is a document issued by manufacturers or designated personnel with authority to assure customers or buyers that the product has been manufactured with test results showing compliance to international or regulatory standards”.
For this to apply the buyer would need to identify on their purchase order what international or regulatory standards they want compliance to. But this not happening in my customer’s case; his customer’s just want a CoC!
Does a CoC have to relate to “international or regulatory standards”?
I believe that it’s reasonable to ask for a CoC to other requirements (size, part number, quantity, dimensions, etc.), but only if this is stated on the purchase order, otherwise the demands for constant CoCs are just somebody being lazy and ticking boxes!
