By James F. Carlin, Jr.' and Keith L. Harris' 
 World tin production increased significantly in 1978 and 1979 in response
to successive years of record high tin prices. The 1978 average Metals Week
composite price of Straits (Malaysian) tin was 629.58 cents per pound, and
increased in 1979 to a new record high of 753.89 cents per pound. These factors
resulted in a slight deficit of supply to demand in 1978, and an approximate
balance of supply and demand in 1979 following many years of a net supply
deficit situation. 
 Legislation and Government Programs.—On September 14, 1978 the
General
Services Administration (GSA) concluded sales of tin authorized for disposal
from the U.S. Government stockpile excess; only 330 
tons was sold in 1978 while shipments totaled 345 tons. Although the stockpile
contained 203,691 tons at yearend 1979 and the goal was 33,021 tons, none
of the numerous bills introduced in Congress to author~ ize additional tin
disposals was enacted. Also, the bill authorizing the U.S. contribution of
up to 5,000 long tons of tin to the ITC buffer stock was not enacted by yearend
1979. The United States continued as a member of the Fifth International
Tin Agreement (ITA), the only metal commodity agreement in which the United
States has participated. 
 The depletion allowances for tin remained 22% for domestic deposits and
14% for foreign deposits.
