931Tin By Keith L. Harris' and James F. Carlin, Jr.' World tin consumption declined while world tin mine production rose in response to prices that reached recor4 highs during 1977. The International Tin Council (ITC) was powerless to stabilize tin prices after exhaustion of its buffer stock in early January, so the price of tin remained above the ITC ceiling price from January 13 throughout the remainder of the year. Little additional tin was available from U.S. Government stockpile excesses. U.S. consumption of primary and secondary tin declined 3% in 1977 to 60,732 metric tons.2 Decreased tinplate production as well as the declining quantity of tin coated on tinplate were major factors causing the decline. The major uses for tin were in tinplate, 31%; solder, 29%; bronze and brass, 14%; chemicals, 9%; and tinning, 4%. Malaysia, Thailand, and Bolivia were the major sources of U.S. tin supplies. Less than 100 tons of tin was produced in Colorado by the only domestic mine. About 22% of the tin consumed in the United States in 1977 was tin reclaimed from scrap. In 1977, the sole primary tin smelter in the United States was the Texas City, Tex., facility of Gulf Chemical & Metallurgical Co. (GCMC). Bolivia's State-owned Corporaciôn Minera de Bolivia (COMIBOL) provided most of the tin concentrate feed for this smelter. In 1977, the average composite price of Straits (Malaysian) tin for New York delivery was at an alltime highof 534.60 cents per pound, $1.55 above the 1976 level. The year marked the first full year of U.S. membership in the Fifth International Tin Agreement (ITA), the first metal commodity agreement in which the United States participated. Legislation and* Government Programs.—The General Services Administration (GSA) continued commercial sales of tin during the year. Sales totaled 2,679 tons, while shipments totaled 2,497 tons. As of December 31, 1977, the U.S. Government stockpile contained 204,176 tons, of which 330 tons was authorized for disposal. The stockpile goal was 33,021 tons.
