(2) For certain end-to-end Package Services pieces originating and/or destinating outside the contiguous 48 states, an 11- to 29-day service standard applies, with the standard generally equaling the sum of 4 to 7 days plus the number of additional days (from 7 to 22) for which certain intermodal (e.g., highway, boat, air-taxi) transportation is utilized.
(b) Destination entry.
(1) Package Services mail that qualifies for a Destination Delivery Unit (DDU) rate has a 1-day (overnight) service standard.
(2) Package Services mail that qualifies for a Destination Local Processing Center (DLPC) (or analogous legacy) rate has a 2-day service standard, except for mail that is destined to either American Samoa or the U.S. Virgin Islands.
(3) Package Services mail that qualifies for a DLPC rate, and that is destined to either American Samoa or the U.S. Virgin Islands, has a 3-day service standard.
(4) Package Services mail that qualifies for a Destination Regional Processing and Distribution Center or Campus (DRPDC) (or analogous legacy) rate, and that originates and destinates in the contiguous 48 states, has a 3-day service standard.
(5) Package Services mail that qualifies for a DRPDC (or analogous legacy) rate, and that is entered in the contiguous 48 states for delivery to addresses in the states of Alaska or Hawaii, or the territories of Guam, American Samoa, Puerto Rico, or the U.S. Virgin Islands, has a service standard of either 11 or 12 days, depending on the 3-digit ZIP Code origin-destination pair. For each such pair, the applicable day within the range is based on the number of days required for transportation outside the contiguous 48 states.
