FOREIGN TRADE 
 The quantity and value of U.S. exports of processed diatomite increased
2% and 11% respectively compared with those of 1976. The quantity exported
(152,388 tons) represented 24% of domestic production in 1977, as in 1976.
Principal destinations were Canada (34,533 tons); Japan (17,918 tons); West
Germany (15,019 tons); the United Kingdom (13,645 tons); and Australia (10,994
tons). 
The average value of exports was $124.18 
per ton compared with $113.64 per ton in 
1976. Diatomite imports totaled only 651 
tons, compared with the record quantity of 
5,154 tons imported in 1976. Canada (33~ 
tons), Mexico (314 tons), and West Germany 
(1 ton), were the import sources in 1977.
