When trading commodities on the market, it is critical that buyers and sellers across the supply chain speak the same trade language. For meat products, large volume buyers – ranging from the federal government to schools, restaurants and hotels – reference the U.S. Institutional Meat Purchase Specifications (IMPS) when making their purchases.

For the first time, the IMPS and poultry and turkey trade descriptions, which are maintained by USDA’s Agricultural Marketing Service (AMS), have been translated into Spanish. These documents are part of a continued effort to expand the use of meat specifications used in the United States, Canada and Mexico for trade. You can also find French translations of these documents through the Canadian Food Inspection Agency.
