FLUORSPAR 
 
 
STOCKS 
 
Fluorspar consumer stocks decreased 61% to about 47,000 tons. 
 
 
PRICES 
423 
 
 Domestic producer prices of all grades of fluorspar and fluorspar briquets
reported in the Engjneering and Mining Journal (E&MJ) remained at
1984
levels. E&MJ yearend price quotations serve as a general guide but
do
not necessarily reflect actual transactions. 
 Yearend price quotations in the Chemical Marketing Reporter (CMR) were $0.6875

per pound for anhydrous HF and $43.00 per 100 pounds for aqueous HF, 70%,
in tanks. The CMR yearend price for cryolite was $550 per ton. CMR yearend
price quotations for fluosiicic acid were $151.00 per ton for 15-gallon drums,
30% basis, and $110.00 per ton for tanks, 23% basis. All of these prices
were unchanged from those of 1984.

FOREIGN TRADE 
 
 According to Bureau of the Census data, U.S. fluorspar exports of all grades
decreased 21% and had an average value of $110 per ton. Synthetic cryolite
exports decreased 24% to 13,000 tons, representing 15,600 tons of equivalent
fluorspar, valued at $5.4 million. 
 Imports for consumption of fluorspar decreased significantly. Acid-grade
imports decreased by 17%, and imports of subacidgrade material decreased
by 34%. Imports from Mexico, the largest foreign supplier, were 51% of the
combined fluorspar total. The Republic of South Africa supplied 33%; Spain,
6%; China, 4%; Italy, 3%; and Morocco, 3%. Small quantities were also imported
from Canada, France, the Federal Republic of Germany, and the United Kingdom.
The average unit value of imported 
acid- and subacid-grade fluorspar was $97.12 and $63.53, respectively. 
 U.S. import duties remained in effect for 
all grades of fluorspar. The duty was $1.875 per ton for acid grade and 13.5%
ad valorem for ceramic and metallurgical grades. 
 Imports for consumption of HF decreased 
slightly to a quantity equivalent to about 
157,000 tons of fluorspar. Imports for consumption of natural and synthetic
cryolite 
decreased 27% and had an average value of 
$603 per ton. Cryolite imports represented 
20,000 tons of equivalent fluorspar. 
 The United States also imported many fluorochemicals, including ammonium
bifluoride, chiorodifluoromethane, dichlorodifluoromethane, fluorocarbon
polymers, hexafluoropropylene, polytetrafluoroethylene, and trichlorodifluoromethane.
