ISO 959-2:2026

Overview

ISO 959-2:2026 is an international standard developed by ISO that defines the requirements and specifications for white pepper (Piper nigrum L.), whether whole or ground, at different commercial stages: semi-processed (SP) and processed (P). This standard sets out the minimum quality criteria, defining both physical and chemical properties, and outlining best practices for sampling, testing, packaging, marking, and recommendations for storage and transport. It specifically addresses white pepper that is not categorized as "light" and provides practical guidance to ensure product quality and food safety throughout the supply chain.

Key Topics

• Definitions and Types

  • Distinction between semi-processed and processed white pepper
  • Explanation of terms such as whole white pepper, ground white pepper, black berries, broken berries, and extraneous matter

• Physical and Chemical Requirements

  • Standards for odour and flavour: characteristic, aromatic, and free from foreign odours and flavours
  • Freedom from mould, insects, and contamination
  • Specifications for extraneous matter, broken berries, black berries, moisture content, volatile and non-volatile oil content, piperine levels, and fibre content

• Sampling and Testing

  • Reference methods for sampling (ISO 948)
  • Testing protocols for conformity with required physical and chemical characteristics

• Packaging and Marking

  • Guidelines for packaging materials to ensure product integrity
  • Requirements for labelling, including product name, batch number, net mass, commercial grade, country of origin, destination, best before date, and reference to ISO 959-2

• Storage and Transport

  • Recommendations for optimal storage: dry, well-ventilated, pest-free, and protected from excessive heat and contamination
  • Guidance for transport to ensure protection from external elements and odours

Applications

ISO 959-2:2026 is widely applied across the food industry, including:

• Pepper producers and exporters: Ensuring white pepper meets global market requirements and food safety standards
• Spice processors and traders: Standardizing quality evaluation, purchasing, and distribution practices
• Importers, wholesalers, and retailers: Verifying product compliance, improving traceability, and consumer confidence
• Quality control laboratories: Using defined test methods for routine analysis, product certification, and regulatory checks
• Food safety authorities and regulators: Reference for inspections, certification, and import/export controls

The standard supports transparent international trade by harmonizing expectations for white pepper quality and handling practices, ensuring consumer safety, and reducing the risk of disputes in commercial transactions.
