The National Organic Program (NOP), administered by the USDA (United States Department of Agriculture), regulates organic production, certification, and labeling in the United States.

Key points:

• Organic farms and processors must comply with NOP standards.

• Only accredited certifying agents can issue organic certificates.

• The program defines allowed and prohibited substances.

• Organic labels (such as “100% Organic” or “Made with Organic Ingredients”) are strictly regulated.

The NOP ensures that all organic products meet consistent standards to protect both producers and consumers.
