As of 2014, the USPS charges $1.15 for first-class letters to the United Arab Emirates that weigh one ounce or less. The same rate applies for all international destinations. Heavier letters and packages require additional postage.
International First-Class Mail options apply solely to letters and large envelopes that weigh less than four pounds total. First-Class Mail is the most affordable mailing solution for international deliveries. All international parcels require a premium delivery service, such as International Priority or Express Mail. Delivery time varies based on the final destination of the item in question. The USPS also provides additional services for international mail, including tracking and delivery confirmation.
