USDA IMPS – NAMP Beef Butchering Specs

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.  It will open in a new window, and it is a 2 MB file so it may take a minute to download.

To purchase the new 2010 NAMP Meat Buyer’s Guide, or the CD, visit the purchase NAMP Meat Buyer’s Guide page.

Visit the Cuts of Beef page for an index of beef primal information which is covered on this site, as well a detailed description of a variety of steak cuts.

Leanne – thanks for the info! A new version of the website rolls out in December (2015) and I’ll include the updated PDF download.


Hi there,

I just wanted to let you know that the link ” download a free Meat Buyers Guide PDF” is very old.  It should be updated with this version

Great website and very helpful!

Thank you,
