Marketing Order Authority and Regulations 
The marketing order authorizes quality regulations and research and promotion programs for walnuts grown in California. The marketing order took effect in 1948. The latest formal rulemaking amendments are effective September 20, 2023. View the full regulation

  • Quality Regulations:  The marketing order authorizes minimum grade and size regulations on walnuts to ensure walnut quality shipped to consumers.

The rule eliminates mandatory inspection and certification of inshell and shelled walnuts, along with shelled walnuts for processing, modifies the California Walnut Board’s calculations of handler assessments, and implements other changes recommended by the Board.
