Overview
ISO 9116:2025, titled "Green coffee - Guidance on methods of specification," is an international standard developed by ISO’s Technical Committee ISO/TC 34 (Food products), Subcommittee SC 15 (Coffee). This third edition provides comprehensive guidance on specifying green coffee for sale and purchase. It outlines accepted methods for describing green coffee lots or consignments and offers procedures on sampling, packing, marking, storage, and shipping of green coffee.
This standard applies specifically to green coffee as defined under ISO 3509 and aims to ensure clarity, uniformity, and reliability in the global trade of green coffee beans.
Key Topics
Specification Methods for Green Coffee
The document recommends including detailed information for each lot or consignment of green coffee to enhance traceability and quality assessment:
- Country and region of origin (state or plantation where relevant)
- Year of harvest or coffee age
- Type of green coffee
- Number of bags and net mass per bag or total net mass for bulk packs
- Moisture content and loss in mass on drying (per ISO 6673; moisture meters calibrated as per ISO 24115)
- Defects and foreign matter content (according to ISO 4149)
- Insect-damaged bean content (as per ISO 6667)
- Bulk density (ISO 6669)
- Bean size (ISO 4150)
Sampling Procedures
Sampling methods for green coffee in bags should follow the guidelines of ISO 4072, ensuring consistent and representative sampling to maintain accuracy in quality control and trade.
Packing, Marking, Storage, and Shipping
- Packing: Use materials that protect green coffee from contamination and damage. Bulk containers must be suitable for maintaining product integrity.
- Marking: Bags and bulk containers must bear clear and permanent markings including "green coffee," country of origin, region or plantation, year of harvest/age, and net mass.
- Storage and Shipping: Handling procedures align with ISO 8455 to preserve the quality of green coffee during storage and transportation.
Applications
ISO 9116:2025 is essential for:
- Coffee producers and exporters to provide standardized and detailed descriptions of green coffee consignments
- Importers, buyers, and traders to evaluate and compare green coffee lots based on harmonized quality parameters
- Quality assurance teams in the coffee supply chain seeking uniform sampling and testing methods
- Logistics and warehouse managers responsible for proper packing, storage, and shipping protocols that maintain coffee quality
- Regulatory and certification bodies promoting compliance with international coffee trade standards
By following this guidance, stakeholders help facilitate transparent, efficient, and quality-driven coffee trade.
