Each item must be fully prepaid to ensure prompt dispatch and to avoid assessment of charges against the addressee. For the treatment of shortpaid and unpaid mail, see 420.
- Postage and fees for extra services (see chapter 3) may be paid by means of U.S. postage stamps, postage meter stamps, or postage validation imprinter (PVI) labels. PVIs are acceptable for all international mail transactions.
- Mailer precanceled stamps may be used with international mail under the same conditions as are applicable to domestic mail. See DMM 604.
- Nondenominated postage stamps (except for those that bear unique domestic markings, such as First-Class Presort, Nonprofit Org.) may be affixed to postal items that are sent to foreign countries. The value of such stamps is linked to either a current or a former domestic rate (e.g., the “Lady Liberty and U.S. Flag” stamp has a postage value of 39 cents). The postage value of the Forever Stamp, as well as the nondenominated Breast Cancer Research semipostal stamp, is always the domestic First-Class Mail single-piece 1-ounce letter rate that is in effect on the day of use (mailing). Since international postage rates are always higher than the comparable domestic postage rates, mailers who affix a single nondenominated postage stamp to their outbound mailpieces must add additional postage to comply with the international rate schedule.
Note: See DMM 604 for stamps not valid as postage.
Postage may be paid by permit imprint, subject to the general conditions stated in DMM 124, 604, and 705. Postage charges are computed on PS Form 3700. This postage payment method may be used for postage
and extra service fees for First-Class Mail International and Priority Mail International.
Mail must be deposited and accepted at the Post Office that issued the permit, at a time and place designated by the postmaster, except as otherwise provided for drop shipments.
To use a permit imprint for international mailing purposes, a mailer must enter a minimum of 200 pieces or 50 pounds of mail matter that is identical in size and weight and addressed to recipients in foreign countries. All of the mailpieces bearing a permit imprint do not have to be addressed to the same destination country. See 292.13 and 293.2 for the minimum quantity requirements that govern the entry of International Priority Airmail (IPA) items and International Surface Air Lift (ISAL) items, respectively.
Note: The 200–piece or 50–pound minimum requirement does not apply to M–Bags.
Each mailpiece sent under this payment method must bear a permit imprint indicia showing that postage is paid. Permit imprint indicias for international mail must be prepared in one of the formats shown in Exhibit 153.24. No variations or additions, such as Bulk Rate, Media Mail, Presorted Standard, Enhanced Carrier Route Sort, Automation Rate, Nonprofit Organization, or Bound Printed Matter, are allowed.
