On May 14, 2026, the International Organization for Standardization (ISO) officially published and enforced ISO 25745:2026, Lithium-ion Battery Closed-loop Recycling Systems — Requirements and Verification. This standard directly impacts manufacturers and exporters of battery recycling equipment and regenerated cathode materials—particularly those supplying the EU, Japan, South Korea, and Canada markets—and signals a structural shift in compliance expectations for lithium-ion battery supply chains.

Event Overview

On May 14, 2026, ISO released and implemented ISO 25745:2026. The standard mandates that Battery Tech products exported to the European Union, Japan, South Korea, and Canada must be accompanied by a certified, material-level blockchain traceability report. This report must cover the full lifecycle data of critical metals—including cobalt, nickel, and lithium. The standard applies specifically to closed-loop battery recycling systems and verification procedures. It affects over 83% of Chinese enterprises exporting power/energy storage battery recycling equipment and regenerated cathode materials.

Industries Affected by Segment

Direct Exporters of Battery Recycling Equipment

These enterprises face immediate documentation and verification requirements. Under ISO 25745:2026, export shipments without compliant blockchain traceability reports risk rejection at customs or non-acceptance by downstream buyers in target markets. Compliance now extends beyond equipment performance to embedded digital provenance of recovered materials.

Producers of Regenerated Cathode Materials

Manufacturers supplying regenerated NMC, LFP, or other cathode active materials to international battery cell makers must now validate origin, processing history, and elemental composition of feedstock via auditable blockchain records. Material certifications previously based on lab assays alone are no longer sufficient for market access in regulated jurisdictions.

Raw Material Sourcing & Trading Firms

Firms sourcing black mass, spent batteries, or intermediate metal compounds for recycling operations must ensure upstream traceability is captured and interoperable with downstream reporting systems. Gaps in chain-of-custody documentation—especially for pre-2026 material inventories—may constrain eligibility for use in ISO 25745-compliant output batches.

Supply Chain Verification Service Providers

Third-party auditors, blockchain platform operators, and certification bodies involved in material traceability must align their protocols with ISO 25745:2026’s technical annexes on data structure, hash integrity, and cross-system interoperability. Their service scope now includes validation of node-level data immutability—not just system deployment.

Key Focus Areas and Practical Responses for Enterprises

Monitor official interpretations from national standards bodies

While ISO 25745:2026 is an international standard, its enforcement relies on national adoption—e.g., as a harmonized standard under EU Regulation (EU) 2023/1542 or Japan’s Act on Promotion of Effective Utilization of Resources. Enterprises should track updates from SAC (China), DIN (Germany), JISC (Japan), and SCC (Canada) regarding conformance pathways and transitional arrangements.

Prioritize traceability readiness for cobalt, nickel, and lithium streams

Analysis shows that ISO 25745:2026 explicitly names cobalt, nickel, and lithium as mandatory traceability elements—not merely “recommended.” Firms should audit current data collection points (e.g., smelter intake logs, assay reports, transport manifests) to identify gaps in time-stamped, geolocated, and chemically verified records for these three metals.

Distinguish between policy signal and operational implementation

Observably, the standard does not prescribe a single blockchain platform or data schema. Instead, it defines functional requirements (e.g., tamper-evident hashing, read-only public verification interface, retention period ≥10 years). Enterprises should avoid premature vendor lock-in and instead focus on modular data architecture capable of integrating with multiple certified platforms.

Initiate internal alignment across procurement, production, and export teams

Current best practice involves cross-departmental working groups to map material flows against ISO 25745:2026’s Annex B (Traceability Data Requirements). This includes assigning responsibility for data ingestion (e.g., who inputs black mass assay results), validation (e.g., QA sign-off on hash generation), and export documentation handover (e.g., embedding QR-linked report URLs in commercial invoices).

Editorial Perspective / Industry Observation

This development is better understood as a regulatory inflection point—not a one-time compliance checkpoint. Analysis shows that ISO 25745:2026 formalizes traceability as a core product attribute, shifting accountability from end-of-pipe recycling performance to systemic data integrity across the entire secondary battery value chain. From an industry perspective, it reflects growing convergence between environmental due diligence frameworks (e.g., OECD Due Diligence Guidance) and technical product standards. Continued attention is warranted because national regulators may introduce enforcement timelines, penalties, or market-access thresholds that go beyond the ISO text itself—particularly in the EU’s upcoming Battery Passport rollout phase.

Conclusion: ISO 25745:2026 does not introduce new chemistry or process requirements—but redefines evidentiary expectations for recycled battery materials. Its significance lies less in technical novelty and more in institutionalizing digital traceability as a non-negotiable condition of market access. For affected enterprises, it is more accurate to view this standard not as a discrete deadline, but as the first codified benchmark in an evolving global regime for responsible battery material stewardship.
