The Postal Service™ would like to remind customers of the markings required for Priority Mail® Commercial Plus® cubic mail prices. Priority Mail Commercial Plus cubic mail has two subcategories, which are cubic mailpieces, and soft pack and padded envelopes.
Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®), sections 202.3.4.1 and 202.3.4.2, provide the marking requirements and placement for cubic mailpieces with regard to the postage payment method. DMM section 202.3.4.1, Price Marking — Postage Evidencing Systems, states that a cubic mailpiece using postage evidencing systems must be marked “Priority Mail” and bear the applicable marking that reflects the correct price tier printed on the piece or produced as part of the postage indicia (e.g., Cubic .10, Cubic .20). DMM section 202.3.4.2, Price Marking — Permit Imprint, states that a cubic mailpiece using a permit imprint must also be marked “Priority Mail,” and bear the “cubic” marking (i.e., “Cubic,” or “CUBIC,” or “cubic”). In both cases, the marking may be placed directly above, directly below, or to the left of the postage.
DMM section 202.3.4.3, Soft Pack and Padded Envelope Markings, states that regardless of the postage payment method used, soft pack and padded envelopes must be marked “Priority Mail” and bear the applicable marking that reflects the correct price tier (e.g., Cubic .10, Cubic .20), along with the dimensions (length and width) of the original packaging. The price tier and dimensions of the original packaging markings may be placed directly above, directly below, or to the left of the postage.
Priority Mail pieces that do not bear a complete cubic price marking, as stated in DMM 202.3.4, are subject to the applicable weight and zone prices. Additional information can be found in DMM sections 202.3.4 and 223.1.4, which are available on the Postal Explorer® website at pe.usps.com.
