Oregon Tilth

Oregon Tilth is an accredited organic certifier that has been operating since 1974, offering certification to the USDA National Organic Program (NOP) standards. The certification applies across the full supply chain — from farmers and growers to processors, handlers, and manufacturers — ensuring that organic practices are consistently maintained at every step between production and the consumer. It is relevant to businesses in consumer goods, agriculture, and manufacturing operating in the United States, Canada, Mexico, Chile, Costa Rica, and China.

To earn and maintain Oregon Tilth certification, applicants must meet strict USDA NOP production and handling standards, undergo on-site inspections, and enter into legally binding contracts that formalize their compliance commitments. This structure is designed to give both producers and buyers confidence that certified products genuinely meet organic requirements.

Oregon Tilth certification is well-suited for any operation — whether a small farm or a large food manufacturer — that wants credible, third-party verification of its organic status. Because Oregon Tilth is USDA-accredited, its certification carries legal standing under U.S. federal organic regulations and is widely recognized across domestic and international markets.
