Figure L—.Trends in the sulfur industry in the United States. 
$477.4 million in 1976, an increase of 2%. Eighty-nine percent of the shipments
was for domestic consumption and 11% for export. Shipments of sulfur in all
forms in 1977 were 1% more than the quantity produced. Producers' yearend
stocks of Frasch and recovered elemental sulfur were almost 2% less than
those at yearend 1976. 
The apparent domestic consumption of sulfur in all forms increased 7% over
that of 1976. Sulfur for domestic consumption was 
obtained mainly from domestic sources: 
Frasch 43%, recovered elemental 30%, and sulfur in other forms 10%. The remaining
17% of the sulfur was obtained by imports of Frasch and recovered elemental
sulfur. 
 The United States was a net importer again in 1*77. Exports of sulfur in
all forms decreased 7% from those of 1976. Imports of sulfur in all forms
in 1977 were 14% greater than in 1976.
