Procurement Review
Qualify the magnet supply route with evidence, not slogans
This page supports procurement review. It identifies the legal and manufacturing entities, which steps are performed where, which steps are subcontracted, and how the approved magnet specification is controlled. Numeric and certification claims are confirmed against current evidence before they are stated.
