Re: Who should do NAFTA certs?
The NAFTA certs have little to do with quality, but everything to do with origin of materials and components used in making a product. In most cases, the final document needs to be a collaboration of Purchasing and Operations to determine which products (if multiple sources are involved) are actually used in the specific products which are the subject of certs.
When I was filling out these documents, we were getting non-ferrous materials from mills located around the world and we had to maintain traceability of which lot of nearly identical material from different countries of origin went into which products we were shipping which required NAFTA documentation. The worst part was the contract requirements did not have a requirement for country of origin, just for NAFTA certificates -
The next important factor is what percentage of the finished product is comprised of subject material - often a question for engineer geeks to calculate!
