The simplified acquisition threshold applies to the cost of supplies and services, exclusive of the cost of transportation and other accessorial costs if their destination is outside the United States.

Accessorial costs means the cost of getting supplies or services to their destination in the cooperating country (and the travel costs of returning personnel to the U.S. or other point of hire). It does not include costs such as allowances or differentials related to maintaining personnel at post which are to be considered as part of the base costs within the simplified acquisition threshold.
