ISO 22927:2021

Overview

ISO 22927:2021 - Rare earth - Packaging and labelling specifies requirements and recommendations for the packaging and labelling of rare earth ores, concentrates, compounds, metals and alloys intended for sale or free distribution. The standard defines packaging performance and structure and prescribes the information to appear on labels to ensure quality assurance, enhance safety and prevent environmental pollution during transportation and storage. ISO 22927:2021 applies to commercial transactions between companies (not to on‑plant storage).

Key Topics

• Scope & terms: definitions for supplier, inner/intermediate/outer packaging, protecting gas/liquid, vacuum and minimum packaging unit.
• Packaging principles: sealed, durable packaging to prevent dispersion, moisture/gas ingress, chemical reaction, quality degradation, fire or pollution.
• Inner and intermediate packaging types:
  • Polymer bottles and film bags
  • Glass bottles (borosilicate)
  • Aluminized polymer bags (for sensitive metals/alloys such as cerium)
• Outer packaging options:
  • Metal drums (note: steel drums >200 L should meet ISO 15750‑1/2/3)
  • Polymer drums and bulk containers
  • Flexible intermediate bulk containers (see ISO 21898)
  • Corrugated fibreboard boxes, kraft bags, wooden/plywood containers
• Protective measures: use of protecting gases (argon, nitrogen), protecting liquids (oils), or vacuum to maintain product stability.
• Labelling requirements:
  • Clear product identity, supplier traceability and handling information
  • Specific labelling recommendations for hazardous materials (e.g., cerium/cerium‑containing flammable alloys, metal powders, products containing radioactive elements)
  • Label format guidance: language, quality and information layout
• Batch and traceability rules: minimum packaging unit should contain product from the same batch/grade/specification.

Applications

ISO 22927:2021 is practical for organizations involved in the global trade of rare earths:

• Suppliers and producers (mines, beneficiation, hydrometallurgy)
• Traders, brokers and blenders
• Packaging engineers and logistics providers handling shipment and storage
• Quality, HSE and regulatory teams ensuring compliance with labelling and transport safety
• Buyers and distributors verifying supplier traceability and safe handling instructions

Adopting ISO 22927 helps reduce incidents (fires, contamination, radiation exposure), preserves product quality during transit, and supports regulatory compliance alongside local transport and SDS requirements.
