United States production.
The domestic production of hexamethylenetetramine declined during the depression, but has been increasing in the last few years. Production in 1937, however, was still below that of 1929. Statistics of production are shown in table [86].

Hexamethylenetetramine is made by two firms in New Jersey and by one in West Virginia. The raw materials utilized are formaldehyde and liquid or anhydrous ammonia. One company makes its own requirements of both, and another makes its own formaldehyde. Most of the production of hexamethylenetetramine is sold, marketed in barrels, drums, kegs, and cans.
Production in other countries.
Hexamethylenetetramine is made in a number of foreign countries, with Germany probably the leading foreign producer. Exports from Germany declined from 445,000 pounds in 1931 to 182,000 pounds in 1934, the decline being due chiefly to the expansion of production in countries previously large importers, particularly the United Kingdom, Japan, Czechoslovakia, and France.
