2011 Priority Mail Cubic Tier Measurement Modification Available for Early Adoption — No Exception Required

When we change our Shipping Services prices on Jan. 2, 2011, a change in the method for calculating Priority Mail commercial plus cubic pricing tiers also will be implemented. 

At that time, when customers are measuring pieces to calculate pricing tiers, any fraction of a measurement should be rounded down to the nearest 0.25 inch, as opposed to the current method of rounding off each measurement to the nearest whole inch. 

In anticipation of this change, and to help ease this transition, the Postal Service will immediately begin accepting Priority Mail commercial plus cubic mailings using the modified measurement approach without our customers having to request an exception for early adoption.

The final rule “Domestic Shipping Services and Mailing Standards Changes” can be viewed on the Postal Explorer^® website at pe.usps.com by clicking on “Federal Register Notices” in the left frame.
