I think this is one of the few places where blockchain would be more help than hurt. Provenance of materials, location of manufacture, even tolerances and standards applied could be tracked across multiple independent companies. Of course, enforcing what goes on the blockchain would be a whole different can of worms. This sort of tracking is important in manufacturing standards (ISO9001). Coupling non-central control of the manufacturing record would be very helpful implementing standards like ISO9001 and allow third party analysis of "manufacturing quality" and "environmental impact" ... even better if it can be integrated into manufacturing instruments that can register a step automatically. Shipping and supply companies are looking heavily into these types of applications.
