U. S. supplies of castor oil are provided chiefly through imports from Brazil and India. U. S. production of castor oil has increased slowly to an estimated 16 million pounds in 1962 but this is still only 12 percent of total annual requirements. Domestic disappearance of castor oil has remained relatively stable since the mid-1950's, averaging about 130 million pounds annually. Paints, varnishes, resins, and plastics account for roughly three-fifths of total disappearance. The outlook for castorbean production in the United States is favorable for a continuation of its slow rate of growth. Increased efficiencies in production are helping to improve the U. S. competitive position with foreign sources.
