Responsible wheat, from field to finished product
Harmony brings responsible wheat production and supply-chain integrity together in one certification scheme — connecting good environmental practices on the farm with the mills, manufacturers and brands that use certified wheat.
Why Harmony was created
Harmony was developed together with farmers, cooperatives, millers, NGOs and environmental experts, and today involves farmers in nine European countries. In 2026 it became a publicly available, third-party certification scheme, now owned and managed by the ProTerra Foundation and open to any farmer, cooperative, miller or brand.

How Harmony certification works
ProTerra Foundation
Owns and maintains the Harmony standards and oversees the certification bodies.
Harmony standards
Set the requirements for wheat farms and for supply-chain companies.
Independent audits
Approved third-party certification bodies audit each operation and issue the certificate.
Two standards, different roles
Harmony Wheat Production Standard
For: wheat farms, individually or as a group.
Covers: crop rotation, soil cover, nutrient and nitrogen management, biodiversity, crop protection, water use and farm records.
Shows: the farm meets the Standard, which combines mandatory requirements with optional practices — its wheat can be sold as Harmony-certified.
Harmony Chain of Custody Standard
For: organisations that buy, store, mill, process or use Harmony-certified material.
Covers: traceability, records and volume control under the model used — segregation, controlled blending or mass balance.
Shows: certified material keeps its identity and integrity, so Harmony claims on products are supported.
Which applies to you? Not every company needs both — your activities decide, and the certification body confirms the scope.
