CFR Citation: 39 CFR Part 111 states, ” The Postal Service is revising the Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM[reg]) to require all mailpieces weighing more than 13 ounces bearing only postage stamps be presented to a Postal Service employee at a retail service counter in a Post Office\TM\. SUMMARY: Stamped Mail Over 13 Ounces Must be Presented at a Retail Service Counter.”
