Customer Support Ruling
Combining Bound Printed Matter Flat-Sized Pieces
This Customer Support Ruling (CSR) provides an additional option to allow mailers to mail Bound Printed Matter (BPM) flat-sized pieces that are no more than 3/4 inch thick that weigh over 20 ounces and up to 24 ounces in a mixed class combined mailing.
Domestic Mail Manual (DMM) 705.15 provides that mailers may combine USPS Marketing Mail, BPM, and Periodicals, machinable flat-sized pieces in a single mailing. The criteria in the DMM states in part, that the maximum weight for automation BPM flat-sized pieces is 20 ounces.
This ruling allows mailers to include in a mixed class combined mailing of USPS Marketing Mail, BPM, and Periodicals, machinable flat-sized pieces, to contain a small percentage of BPM pieces that weigh up to 24 ounces maximum. Specifically, we will allow up to 25% of BPM pieces in the non-carrier route portion of the comail pool to weigh more than 20 ounces up to 24 ounces and be comailed under DMM 705.15.
In reference to CSR PS-325, Combining Periodicals Flat-Sized Pieces, which also allows up to 25% of Periodicals pieces in the non-carrier route portion of the comail pool to weigh more than 20 ounces up to 24 ounces, mailers can only use the 25% allowance for pieces weighing up to 24 ounces for either Periodicals or BPM pieces in a mixed class mailing.
The Postal Service reserves the right to rescind this CSR if we discover any operational impacts due to this support ruling.
