Traceability of rare earths in the supply chain from separated products to permanent magnets ISO 17887:2025

Publication date:   Aug 8, 2025

Scope

This document specifies ways in which rare earths can be traced as they move through the supply chain between the separated products to rare earth permanent magnets, or otherwise to be further processed.
The documented traceability information is applicable to purchasers, suppliers, and users of rare earth permanent magnets to identify parties in the supply chain who have processed a given shipment of rare earth material, the location of that rare earth material as it passes between supply chain nodes. The documented traceability information is also applicable to supply chain actors and end users who use this information to check the validity of any claims made on the rare earth permanent magnets concerning sustainability, environmental impact, or recycled material content.
