Overview
ISO 17887:2025 - Traceability of rare earths in the supply chain from separated products to permanent magnets - is a first-edition ISO standard that specifies how rare earth materials are traced as they move from separated products (e.g., oxides) through to rare earth permanent magnets or further processing. The standard defines documented traceability information for purchasers, suppliers and users to identify parties, locations and movements of rare earth material, and to verify claims about sustainability, environmental impact, and recycled material content.
Key Topics and Requirements
The document lays out the structure and operation of a traceability system and includes these technical topics:
- Planning a traceability system
- Documented information, counterparties, and the use of a Unique Identifier (UI).
- Operation of the traceability system
- Chain of custody principles and chain of custody requirements.
- Product and shipment identification as materials move between supply chain nodes.
- Digital traceability platforms
- Support for distributed-ledger-based (blockchain-style) traceability platforms.
- Core elements: supply chain node definitions, transactions, context, events, transformations.
- Data privacy, security and interoperability considerations.
- Performance evaluation and continual improvement
- Monitoring traceability performance, handling nonconformities and corrective actions.
- Scope of supply chain actors
- Separation production, metal and master alloy production, magnet production (e.g., NdPrFeB), traders, recyclers, transporters and downstream users.
- Annex material describing nodes with and without transformations.
The standard is intentionally technology-neutral while specifying digital verifiability and chain-of-custody documentation.
Applications and Who Uses It
ISO 17887:2025 is practical for organizations that need credible proof of material origin and processing steps across the rare earth supply chain, including:
- Magnet manufacturers and magnet-making precursor suppliers
- Separation plants, metal and master-alloy producers
- Traders, brokers, transporters and recyclers handling rare-earth-bearing materials
- OEMs and downstream users integrating permanent magnets (e.g., electric motors, wind turbines, consumer electronics)
- Purchasing, compliance and sustainability teams verifying recycled content or environmental claims
Use cases include supplier due diligence, sustainability claims verification, circular-economy reporting, regulatory compliance, and deployment of digital traceability solutions.
