OPT Grass-Fed Organic Certification Application
What To Know About Applying For OPT Grass-Fed Organic Certification
TLDR: Oregon Tilth offers OPT Certified Grass-Fed Organic certification in partnership with the Organic Plus Trust (OPT). This optional program is for certified organic farmers and handlers who emphasize pasture-based feeding and animal welfare, while limiting grain use. The application fee is a flat $350, in addition to your regular organic certification fees. Forms must be submitted to your Oregon Tilth client service team.
What Is OPT Grass-Fed Organic Certification?
OPT Grass-Fed Organic is a voluntary certification that builds upon USDA National Organic Program (NOP) requirements. It recognizes farms and businesses that:
- Maximize pasture grazing
- Limit or eliminate grain-based feeds

This certification helps differentiate your livestock products in the marketplace as fully pasture-based and aligned with animal well-being practices.

- Produce or handle livestock or livestock products
