Publication 51 Revision: Priority Mail International Flat-Rate Envelope and Small Flat-Rate Box Availability

Effective April 6, 2009, the Postal Service™ is revising Publication 51, International Postal Prices and Fees, in the Country Listing table to authorize the following:

n The Priority Mail International® flat-rate envelope and small flat-rate box are authorized for shipment to Ascension and the Falkland Islands.

n The Priority Mail International flat-rate envelope is authorized for shipment to the Democratic People’s Republic of Korea (North Korea) — the small flat-rate box is not admissible to North Korea. Items sent to North Korea in the flat-rate envelope may not contain dutiable items or merchandise.

The maximum weight for both the Priority Mail Interna­tional flat-rate envelope and small flat-rate box is 4 pounds.

We will incorporate these revisions into the next printed version and into the next online update of Publication 51, which is available via Postal Explorer® at
