FOREIGN TRADE 
 
 
 U.S. exports classified as feldspar, leucite, and nepheline syenite, but
presumably mostly feldspar, decreased 8% to 9,280 tons valued at $680,000.
Chief recipients were Canada, 51%; the Dominican Republic, 18%; Mexico, 11%;
and Taiwan, 6%. The remaining 14% was shared among eight other countries.

 In addition to feldspar and nepheline syenite, the United States imported
580 tons of "Other mineral fluxes, crushed" 
with a value of $323,000. This represented a 59% decrease in tonnage compared
with that of 1984. Also, 60,400 tons of "Other crude natural mineral
fluxes"
was imported with a value of about $3.0 million. This was a 39% decrease
in tonnage compared with that of 1984. 
 The tariff schedule in force throughout 
1985 for most favored nations provided for a 
3.0% ad valorem duty on ground feldspar; 
imports of unground feldspar were admitted duty free.
