Beef Round Cuts

The round comes off the back leg of the carcass and carries roughly 22 percent of the weight, making it one of the two largest beef primals alongside the chuck. The major sub-primals are the inside round (top inside, IMPS 168), the outside round (flat, IMPS 171B), the eye of round (IMPS 171C), the bottom gooseneck (IMPS 171), and the knuckle (IMPS 167A). Round is the leanest primal of the carcass and the one most often substituted into Select-grade programs. Round sub-primals flow into a different demand mix than middle meats. Inside rounds anchor roast beef sandwich programs, retail oven-roast cases, and export. Eye of round and knuckle move into deli and roast applications. Outside round and gooseneck pieces flow into corned beef, jerky, and lower-fat ground formulations. Because the round is large and demand is fragmented across many channels, no single channel dominates round pricing the way steakhouse demand dominates loin pricing. The round prints daily in the USDA AMS National Daily Boxed Beef Cutout report (LM_XB403) under both Choice and Select grades. Round is also the primal where the Choice/Select spread runs the narrowest of any major primal, because the demand applications (roasting, deli, export) put a smaller premium on marbling than the steak programs that pull rib and loin.
