FOREIGN TRADE 
 
 The gypsum industry continued to rely on imports of crude gypsum rock for
a significant fraction, 33%, of apparent consumption. Imports of crude gypsum,
principally from Canada, 66%; Mexico, 22%; and Spain, 12%, increased 11%
to 9.9 million tons. Spanish imports into the South Atlantic Coast and Gulf
Coast States increased 31% to 1.2 million tons. Most of the imported 
crude gypsum was mined by subsidiaries of U.S. companies in Canada and Mexico.
Total value of gypsum and gypsum products imported was $155 million, a decrease
of 8%. Gypsum wallboard imports, principally from Canada, 82%, were 786 million
square feet, a 9% decrease. Total value of gypsum product exports to all
countries was $26 million, a 12% decrease.
