_France._—Naphthalene is produced in France by a number of manufacturers, most of whom consume their production in their own factories. The French output is said to be insufficient to meet domestic requirements. Estimated production is given as approximately 30 million pounds annually. Appreciable quantities are imported from nearby countries. Imports from Belgium in recent years average between 1 million and 3 million pounds. _Poland._—Production of crude naphthalene in Poland is shown in table 41.

Exports in recent years, however, have averaged about 10 million pounds annually. It is believed that the production of crude naphthalene exceeds 15 million pounds a year. Table 95 (see p. 148) shows Netherland imports and exports of naphthalene by countries in recent years. Imports in 1937 amounted to 2 million pounds and exports to 15 million pounds. _Canada._—Statistics of production are not available. The annual output of crude naphthalene is estimated at 2 to 3 million pounds. Imports of refined naphthalene are usually about 1 million pounds (see table 96, p. 150). Exports are probably small, although in 1929 and 1934 those to the United States alone were over 1 million pounds. _The Soviet Union._—Statistics of production of naphthalene in the Soviet Union are not available. The annual output has been estimated at 10 million pounds in 1933 and 15 million pounds in 1935. Exports have increased substantially in recent years, those to the United States from 1 million pounds in 1934 to 6 million pounds in 1935. Exports to Germany were 361 thousand pounds in 1933; 1 million pounds in 1934; and 531 thousand pounds in 1935. _Japan._—Japanese production of naphthalene has been small compared with the output of other tar products. The output of crude naphthalene in 1934 was reported to have been 381 thousand pounds. Expansion of the byproduct coking industry in Japan and Manchuria has increased the production of coal tar, byproduct ammonia, and benzol. Japan has imported large quantities of naphthalene in recent years, principally from Germany and Belgium. The increased consumption in Europe may so reduce supplies from these sources as to cause Japan to increase the recovery at home. Japanese imports of naphthalene from principal sources, are shown in table 97 (see p. 150). In 1936, 12.6 million pounds were imported. United States imports.
