Federal statute (7 USC 1637b) requires USDA to collect and release dairy product sales information for butter, cheddar cheese, dry whey, and nonfat dry milk, no later than 3 p.m. ET on Wednesday of each week (unless affected by a Federal Holiday). The regulations for the Dairy Product Mandatory Reporting Program (DPMRP) can be found in 7 CFR 1170. The data in the National Dairy Products Sales Report (NDPSR) are also used in the price calculations for the Federal Milk Marketing Orders (7 CFR 1000.53). Entities producing and selling one million pounds or more of these products per year are required to report their weekly sales information to AMS as part of the DPMRP. This data is then reviewed, analyzed, and used to compute prices that are published in the National Dairy Products Sales Report (NDPSR). The market-determined prices, published in the NDPSR, are used in the formulas to calculate raw milk prices paid by handlers based on the end-use or “classification” of milk.
