Amid growing pressure on global food systems, the UNECE Specialized Section on Standardization of Seed Potatoes (GE.6) is working on practical solutions to improve certification systems that protect agricultural production and facilitate trade. The UNECE Standard for Seed Potatoes (S-1) — first adopted in 1963 and fully revised in 2025 — establishes internationally agreed minimum certification requirements, covering varietal identity, traceability, pest and disease control, tuber size, and labeling. Used worldwide as a benchmark, the standard helps align national certification systems, build trust between trading partners, and reduce uncertainty in cross-border trade. For instance, in the Netherlands — the world’s largest seed potato exporter — the Dutch Inspection Service (NAK) certified about 823,000 tonnes for export in 2024, while South Africa certifies around 170,000 tonnes annually for domestic use and regional export to Zimbabwe, Botswana, and Namibia.
Beyond updating the standard, the Section develops practical guides on implementing certification systems, field and lot inspection, and identifying diseases and pests. A recent joint webinar between UNECE and the World Potato Congress attracted over 130 participants from 42 countries, reflecting strong global interest in harmonized approaches. The UNECE plans additional webinars to raise awareness and promote the adoption of the revised standard through seed potato certification schemes, ultimately contributing to higher yields and more resilient food systems worldwide.
