FAR Part 19, 19.000 (B ) states that "This part, except for subpart 19.6, applies only in the United States or its outlying areas" Our Small Business advisor insists that we complete a DD 2579 for acquisitions in foreign country, because the contracting office is located in the United States. We support many overseas missions, and often have to buy supplies and services in foreign countries. Is it required that we consider US Small Businesses when the mission dictates that we acquire supplies and services in foreign countries, if the contracting office is located in the US?
