USDA Beef Grading Standards Under Review for Update
USDA beef grading standards may soon change, and the U.S. Department of Agriculture wants to hear from the people who know cattle best. On July 8, 2026, the Agricultural Marketing Service announced it is seeking public comments on revisions to the United States Standards for Grades of Carcass Beef. Producers, packers, and buyers have until September 8, 2026, to weigh in. The review could reshape how the nation’s beef is measured, marketed, and valued.
Why USDA Beef Grading Standards Matter
For decades, USDA quality grades have helped buyers and sellers speak the same language. Grades like Prime, Choice, and Select tell shoppers and restaurants what to expect on the plate. Meanwhile, they signal to ranchers which genetics and feeding choices pay off at market.
The grades rest mainly on two things. First, marbling, the flecks of fat within the muscle. Second, the animal’s physiological maturity. Together, these factors predict how tender and flavorful the cooked beef will be. Because these standards guide real money decisions, keeping them accurate matters to everyone in the supply chain.
A Push for New Marbling Degrees
The current review began with a petition from the American Wagyu Association. Today, the Prime grade includes four marbling degrees: Slightly Abundant, Moderately Abundant, Abundant, and Very Abundant. However, modern cattle are producing beef that stretches beyond those categories.
The numbers tell the story. In 2017, only 6.2% of carcasses graded Prime. By 2025, that figure had climbed to 12.2%. Advances in genetics, feeding, and husbandry have driven this rise. As a result, some carcasses now show marbling that the existing degrees cannot fully capture. The petition asks USDA to consider adding new marbling degrees so the Prime grade reflects what producers are actually raising.
Rethinking Maturity Rules for Younger Cattle
USDA is also asking a second big question. Should the agency drop the skeletal maturity requirement for carcasses that dentition shows to be under 30 months of age?
Maturity groups were never meant to pinpoint an animal’s exact age. Instead, they aim to predict eating quality. Yet diet, breed, and environment can push a young animal into an older maturity group on paper. Consequently, some tender, high quality beef gets classified lower than it should.
Research supports a change. A study led by Dr. Belk and colleagues at Colorado State University found that grain fed steers and heifers under 30 months eat much like maturity group A carcasses. Therefore, letting dentition and age verification take priority over physiological maturity could allow more carcasses to qualify for Prime, Choice, and Select. Importantly, USDA says this would happen without weakening the grades’ reliability in predicting palatability.
More Questions on the Table
The agency’s notice reaches beyond marbling and maturity. AMS acknowledges ongoing industry debate about yield grade calculations, which estimate how much boneless retail meat a carcass yields. While the science is not settled, USDA is not turning away comments on that topic either.
Additionally, the agency posed ten questions to guide feedback. It wants to know how the standards can keep pace with new technology. Furthermore, it is asking whether any marbling degrees have become outdated. Officials also want ideas on making U.S. beef more competitive in international markets.
How Producers Can Share Their Voice
This is a genuine invitation to participate, and the process rewards those who speak up. AMS plans to review every comment and consider next steps supported by stakeholders. If the agency moves forward with revisions, it will publish a draft of the updated standards for another round of comment.
For example, a rancher who has watched high marbling cattle get boxed into limited grades can share that firsthand experience. Meanwhile, a processor or volume food buyer can explain what works and what does not. Because all comments are posted publicly, transparency runs through the entire effort.
What Comes Next for Beef Grades
The stakes are real for the whole beef community. Updated USDA beef grading standards could reward producers for the quality they work hard to raise. They could also give buyers clearer information and help American beef compete abroad.
For now, the ball is in the industry’s court. USDA is listening, and the comment window closes September 8, 2026. Ranchers, packers, and buyers who care about how their beef is graded should watch this process closely and consider adding their voice while there is still time.
Producers and industry members can read the full notice and submit comments at regulations.gov under docket number AMS-LP-25-0485, or contact Chad Nelson at the USDA Livestock and Poultry Program.
