STOCKS 
 Consumer stocks of gallium metal at and high-purity grades, are shown in
table yearend 1978 and 1979, both commercial 3. 
PRICES 
Throughout 1978, the American Metal 
Market quoted prices for metal of 99.9999% 
purity at $500 to $600 per kilo in 100- 
kilogram lots. At the end of 1979, the price 
was quoted at $510 per kilogram in 100kilogram lots. Gallium prices are subject
to negotiation between buyer and seller. 
FOREIGN TRADE 
 Data on the export of gallium metal and compounds are not reported separately
but are included in the export category "base metals and alloys, not
elsewhere
classified, wrought or unwrought, waste and scrap." Significant quantities
of gallium and gallium compounds are exported as parts of manufactured gallium-based
electronic and electrical components and equipment. 
 Imports of gallium in 1978 and 1979 increased substantially in quantity
and value from those of 1977 and augmented the U.S. supply available for
consumption. In both years, Switzerland was the major source of imported
metal. The average value of imported metal declined from $430.51 per kilogram
in 1977 to $415.28 in 1978 and increased to $417.37 in 1979.
