The International Tin Council (ITC) was an organisation which acted on behalf of major tin producers and consumers to control the International tin market. It is no longer active.
An International Tin Study Group, which was established in 1947 to survey world supply of and demand for tin, led to the treaty, the International Tin Agreement, signed in 1954, and the formation of the ITC in 1956.
The objectives were to:
The original members were:
After the 1954 agreement, 5 more agreements were signed every five years, in 1960, 1965, 1970, 1975, and 1980.
By the sixth agreement, established at the United Nations Tin Conference, 1980, new consumers included Finland, Greece, Ireland, Luxembourg, Norway, Portugal, and Sweden. New producers were Australia, Brazil and Zaire.
At various times Guinea, Mexico, Republic of Korea, the United Arab Republic, Israel, Liberia, Panama, Yugoslavia, Union of Soviet Socialist Republics, Poland, the Philippines, Czechoslovakia, Taiwan, Romania, Nicaragua, German Democratic Republic, and Austria held membership.
With the advent of aluminium containers, the use of protective polymer lacquers inside cans, and increased recycling by industry, the demand for tin decreased considerably by the early 1980s, and in October 1985 the ITC could no longer maintain the price. It eventually ran out of money buying up tin on the metals markets. Attempts to refinance the ITC were eventually abandoned, and since then, as with many other raw materials, the price has generally declined as alternatives become more attractive.
