Export Control Act

The Export Control Act of 1940 was one in a series of legislative efforts by the US government and initially the administration of President Franklin D. Roosevelt to accomplish two tasks: to avoid scarcity of critical commodities in a likely prewar environment and to limit the exportation of materiel to Imperial Japan. The act originated as a presidential proclamation by Roosevelt forbidding the exporting of aircraft parts, chemicals, and minerals without a license, and it was intended to induce Japan to curtail its occupation of the coast of Indochina. The text stated that whenever the President deemed it "necessary in the interest of national defense," he could prohibit or curtail the exportation of military equipment, munitions, tools, and materials. Although controls were first authorized in 1940 in regard to munitions and similar materials essential to the defense effort, the ban of oil and steel exports to Japan took effect in June-August of 1941. Its coverage was extended in 1942 to all commodities and broader geographic coverage after the United States entered World War II. The act was extended with modifications through 1948, and it was envisioned that remaining controls would soon disappear at the time of re-enactment in 1949.…
