The Butterfat Test of Producer Milk Used in Class I Products is the percentage of butterfat found in Class I milk for each order for each month.

The Class I Milk Price for each Federal Milk Marketing Order is determined by adding the Class I differential for the particular county location of the regulated handler to the monthly Class I Mover (the nationwide Class I price before any Class I differentials are added). The Class I Milk Price listed in the table is at the order's base location. The Class I Milk Price represents the minimum milk price required to be paid by regulated handlers to producers pooled under the Federal Milk Marketing Order program for milk used to produce Class I Fluid Milk products. The Class I Price is specific to a Federal Milk Marketing Order's principal base pricing point or the physical location of the Class I pool plant. The All Markets Combined is a weighted average of all the Orders but is based on the order’s Class I milk pounds at the Order’s base location.
