The IFOAM's Organic Guarantee System assures organic integrity internationally. In the rapidly growing environment of marketing and trade of products claiming to be "organic," IFOAM provides a market guarantee of the integrity of organic claims. The Organic Guarantee System (OGS) unites the organic world through a common system of standards, verification, and market identity. It fosters equivalence among participating certifiers, paving the way for more orderly and reliable trade.

The IFOAM Organic Guarantee System enables organic certifiers to become "IFOAM Accredited" and for their certified operators to label products with the IFOAM Seal next to the logo of their IFOAM accredited certifier. Accreditation is based on the certifier's compliance with IFOAM norms.
