There are five principal categories of international mail that are primarily differentiated from one another by speed of service. They are Global Express Guaranteed® (GXG®) service, Express Mail International® service, Priority Mail International service, First-Class Mail International service, and First-Class Package International Service™.
Global Express Guaranteed is the U.S. Postal Service’s premium international mail service. Global Express Guaranteed is an expedited delivery service that is the product of a business alliance between the U.S. Postal Service and FedEx Corporation. It provides reliable, high–speed, time–definite service from designated U.S. ZIP Code™ areas to locations in most destination countries. Global Express Guaranteed is assured to meet destination–specific delivery standards or the postage will be refunded. If a shipment is lost or damaged, liability for loss or damaged merchandise or for document reconstruction is limited to a maximum of $100 or the amount of additional optional insurance purchased. The maximum weight limit for Global Express Guaranteed service is 70 pounds, but lower country-specific weight limits might apply. To determine the maximum weight limit for each country, see the Individual Country Listings or Publication 141, Global Express Guaranteed Service Guide.
The next level of service, in terms of speed and value-added features, is Express Mail International. Express Mail International is an expedited mail service that can be used to send documents and merchandise to most of the country locations that are individually listed in this publication. Express Mail International insurance coverage against loss, damage, or missing contents, up to a maximum of $100, is provided at no additional charge. Additional merchandise insurance coverage up to $5,000 may be purchased at the sender’s option to many countries. Document reconstruction insurance coverage is limited to a maximum of $100 per shipment. Country-specific maximum weight limits range from 22 pounds to 70 pounds. See the Individual Country Listings.

For all other destinations, Express Mail International shipments are not subject to a postage refund guarantee if a delivery delay occurs.

For countries that offer parcel service, maximum weight limits range from 22 pounds to 70 pounds. To determine the maximum weight limit for each country, see the Individual Country Listings.
