International arrival of parcels into the USA has delays up to a week due to restrictions by Transportation Security Administration (TSA)

Information on Inbound International Mail Due to recent incidents involving international cargo, the Transportation Security Administration (TSA) instituted heightened security measures to safeguard air transport. These directives apply to U.S. bound international mail and cargo. The U.S. Postal Service is working with the Universal Postal Union (UPU) and the designated postal operators of its member countries to provide support and assistance in adhering to these TSA directives.
In December 2010, the holiday surge in international mail volume to the U.S., along with severe weather conditions in many parts of Europe and limited availability of air transport, contributed to widespread delays in transit times for international mail bound for the U.S. In addition, airlines operating at major air transit hubs have been unable to provide mail transit services for postal packets and parcels.
Since that time, a world-wide effort among UPU members and postal operators to meet the requirements of the new TSA directives has resulted in improvements in transit times for international mail bound for the U.S.

However, international packages from some points outside the U.S. may be subject to delays of several days above normal transit times as foreign postal operators continue to make progress in implementing the necessary adjustments to their operations. The U.S. Postal Service regrets any inconvenience these temporary increases in transit times may create for its customers.
