On June 25th, the Postal Regulatory Commission denied the USPS’s December 2024 request to remove Bound Printed Matter (BPM) Flats and Bound Printed Matter Parcels from the Market Dominant product list. The Commission also ruled in favor of a separate USPS notice of a set of changes to raise the weight limits for USPS Marketing Mail Parcels and for flat-shaped mailpieces within three USPS Marketing Mail products (High Density and Saturation Flats/Parcels, Carrier Route, and Flats).
This represents a victory for ACMA members. Teaming up with PostCom and other like-minded organizations, we submitted comments in March (link) and reply comments (link) in April both urging the PRC to reject the proposal. In its proposal, the Postal Service justified eliminating BPM in part by reference to its companion proposal to increase the maximum weight of Marketing Mail, claiming that if it did so, “the BPM products would become duplicative.”
BPM evolved out of the former fourth class mail, often used for shipping phone books.
Setting aside any questions of pricing, that statement would be true for only a portion of BPM — the portion that accommodates catalogs, advertising, and promotional materials. Heavyweight Marketing Mail would not be duplicative of BPM for fulfillment matter and books without advertising because those mailings are not eligible for Marketing Mail.
Thus, the Postal Service would re-create the prior situation where eligibility for the rate depends entirely on the inclusion of advertising in the mailpiece.
