USDA-ERS published U.S. meat and livestock trade data through September 2026. The data cover the first month of the expanded tariff-rate quota for imported lean beef trimmings, and cull cow prices declined over the period.
Higher lean trimmings imports under the expanded quota add beef supply for grinding, which can ease prices for lean trim. Weaker cull cow prices reduce the value of the cow herd's lower-grade slaughter animals.
After 65 past neutral trade events, Live Cattle moved a median +0.3% over 5 sessions (57% higher; middle half -0.5% to +1.4%), and +2.5% over 20.
