Hunt v. Washington State Apple Advertising Commission, 432 U.S. 333 (1977) was a case in which the Supreme Court of the United States unanimously struck down a North Carolina law prohibiting the sale of apples in closed containers marked with any apple grade other than the United States Department of Agriculture grade. However, displaying the USDA grade was not required. Washington state, a major apple producer, used apple standards superior to those used by the USDA. The Court found that North Carolina's law violated the Commerce Clause by discriminating against Washington state apple producers while working to the advantage of local North Carolina apple growers.
