NAMP Meat Buyers Guide
The Meat Buyers Guide NAMP (National Association of Meat Purveyors) and the IMPS (Institutional Meat Purchase Specifications) use identical specs, but the IMPS is put out by a government agency and is free. Click on the USDA IMPS for Fresh Beef link to download a free Meat Buyers Guide PDF version of the Beef file which includes NAMP/IMPS item numbers, descriptions and pictures of the cuts.
