DMM Revision: USPS Marketing Mail Nonautomation Flat-Size Pieces Failing Deflection

Effective October 7, 2019, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®), Exhibit 201.4.7b, to clarify the price for USPS Marketing Mail® nonautomation flat-size pieces that fail deflection.

DMM Exhibit 201.4.7b, “Pricing for Flats Exceeding Maximum Deflection,” stipulates that customers mailing flat-size pieces that do not meet deflection standards must pay the applicable prices as noted in the exhibit. Exhibit 201.4.7b specifies that customers mailing USPS Marketing Mail nonautomation flat-size pieces, at all sort levels, pay the applicable Mixed Area Distribution Center (ADC) destination entry price.

However, nonautomation Mixed ADC flats are not eligible for destination sectional center facility (DSCF) entry. Therefore, nonautomation flats at all sort levels cannot default to a DSCF Mixed ADC entry price for failed deflection.

As a result, the Postal Service is clarifying that nonautomation flat-size pieces at all sort levels eligible for DSCF entry that fail deflection are subject to the Mixed ADC destination network distribution center (DNDC) price. This applies to piece prices (4 oz. or less and more than 4 oz.) and pound prices.

Although the Postal Service will not publish these revisions in the DMM until October 7, 2019, the standards are effective immediately.
