730 Shortpaid Mail to the United States

731 Computation of Postage Due

1. The postal service of the country of origin identifies and marks shortpaid mail with a T stamp. Next to the T is a fraction that consists of the amount of postage deficiency (expressed in its own currency) divided by the country’s international surface letter rate at the first increment.
2. The receiving exchange office in the United States multiplies the T fraction by the U.S. First–Class Mail International letter rate to determine the short paid amount in U.S. currency. This amount, plus a $0.50 handling charge, accounts for the postage-due amount to be collected on delivery. The postage-due formula is as follows:



3. The receiving exchange office in the U.S. will imprint stock rubber stamp R–1300–4, Postage Due…Cents, and enter the amount of postage due.
4. The delivery office will collect postage–due mail in accordance with DMM 604 and Handbook F–1, Post Office Accounting Procedures.
