The first shipments of 300,000 metric tons of tariff-free beef that President Donald Trump says will be sold to U.S. consumers at a discount are entering the country this week. The imports consist of lean beef trimmings, which processors blend with fatty domestic beef to produce standard ground-beef mixes such as 80/20 and 90/10. Trump said the meat is coming from Argentina, Brazil and a couple of other countries. The volume represents about 2% of U.S. domestic beef consumption, but agricultural economists David Anderson of Texas A&M University and Glynn Tonsor of Kansas State University said tariff relief is unlikely to produce a meaningful decline in retail prices. The plan has drawn criticism from Republican lawmakers, ranchers and cattle-industry groups as the U.S. cattle herd stands at a 75-year low. Consumers concerned about origin can look for labels such as Product of USA, Made in the USA, Born, Raised, and Harvested in the USA, or American Grassfed Association (AGA) Certified, while checking country-of-origin information and USDA inspection establishment numbers.
