(a) The rules in this part require the Postal Regulatory Commission to establish and maintain lists of Postal Service products and a Mail Classification Schedule.

(b) The product lists shall categorize postal products as either market dominant or competitive. As established, the market dominant and competitive product lists shall be consistent with the market dominant products identified in 39 U.S.C. 3621(a) and the competitive products identified in 39 U.S.C. 3631(a). The market dominant and competitive product lists shall also include products identified as market tests pursuant to 39 U.S.C. 3641 and nonpostal pursuant to 39 U.S.C. 404(e).

(c) The Mail Classification Schedule shall provide current price and classification information applicable to the products appearing on the market dominant and competitive product lists.

(d) Once established, the product lists and the Mail Classification Schedule may be modified subject to the procedures specified in this part.

(e) Modification of the competitive product list to add a competitive negotiated service agreement is not governed by this part but is governed by part 3041 of this chapter. The rules in part 3041 of this chapter regarding removal of a negotiated service agreement from the competitive product list supersede any conflicting rules in this part.
