Rare Earth Permanent Magnet Materials Blockchain Data Sharing Technical Specifications

1 Scope

GB/T 47011-2026 is the Chinese national standard covering tracing rare earth magnets on a ledger - the production, composition and provenance data recorded at each step from separation to finished magnet, and shared with customers who increasingly have to prove where their material came from. First edition, and it belongs with the magnet carbon footprint standard GB/T 47102-2026. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the overall architecture, data sharing process, basic data conventions, and other aspects of blockchain data sharing for rare earth permanent magnet materials. Requirements for magnetic blockchain technology. This document applies to the construction, management, and application of a blockchain-based data sharing service platform for the rare earth permanent magnet industry chain, providing a basis for rare earth permanent magnet materials. Data provision and distribution across industries, enterprises, and departments in business scenarios such as R&D, design, manufacturing, service application, and recycling of materials or products. Data application services such as current access, use, sharing, traceability, evaluation, and security monitoring.
