I have the same concern. The Chinese have been known for forge origination documents. A lot of the stuff my company manufactures requires that we have complete traceability. Mill test reports, Melt numbers, etc. If the Chinese begin a program of phoney MTR’s to hide the origination of their material, traceabilty goes out the window. When something fails because a component fractured, all that stuff comes into play in a court case so the “paper trail” has to be correct.
OTOH, it should be detectable. The Chinese can’t just wash their metals through any old country... it would have to look like it came from a country that has a significant manufacturing capacity in that product range — like South Korea, for instance.
