Overview
ISO 959-1:2026 is an international standard developed by the International Organization for Standardization (ISO) that establishes specifications for black pepper (Piper nigrum L.), whole or ground. This document applies to black pepper at various commercial stages, including non-processed, semi-processed, and processed forms, but excludes black pepper categorized as "light." The standard outlines comprehensive requirements regarding quality, safety, physical and chemical properties, packing, and marking, aimed at ensuring consistency in international trade and consumer safety.
By providing a unified reference, ISO 959-1:2026 aids producers, traders, authorities, and laboratories in achieving and verifying compliance for black pepper products intended for local and global markets.
Key Topics
-
Product Scope
Covers both whole and ground black pepper across non-processed (NP), semi-processed (SP), and processed (P) commercial stages.
-
Quality Requirements
Specifies odour, flavour, and appearance, mandating that black pepper be aromatic and sharp in taste, free from foreign odour and taints.
-
Contaminant Control
Requires products to be free from mould, living insects, and minimization of dead insects and rodent contamination, verified through visual or magnified inspection.
-
Physical and Chemical Properties
Sets maximum limits for extraneous matter, light berries, pinheads, broken berries, moisture content, ash, volatile oil, piperine content, and more.
-
Sampling and Test Methods
References ISO methods for sampling, chemical analysis, and physical testing for conformity assessment.
-
Packaging and Marking
Details packaging integrity to prevent contamination and moisture ingress, and labels must state product type, batch, producer, country, destination, best before date, and ISO reference.
-
Storage and Transport
Recommends clean, dry storage, protection from pests, odors, and heat, as well as proper ventilation and handling during transport.
