United States imports.

Rates of duty.—Prior to September 8, 1916, all grades of naphthalene were imported free of duty. Since that time crude naphthalene has remained free but refined naphthalene has been subject to the tariff treatment shown in table [42].

¹ Ad valorem based on American selling price or United States value.

² Generalized to all countries which do not discriminate against United States products.

Under the Tariff Act of 1930, crude naphthalene is on the free list[18] and refined naphthalene is dutiable at 7 cents per pound and 40 percent ad valorem on the basis of American selling price, since it is competitive with refined naphthalene produced in this country.[19] Under the trade agreement with Belgium, effective May 1, 1935, the duty on refined naphthalene was reduced to 20 percent[20] ad valorem and 3½ cents per pound on imports from that country. Under the Trade Agreements Act this reduction applies also to imports from all other countries which do not discriminate against commerce of the United States. In July 1938 Germany was the only one not receiving the reduced rate, exports from that country being subject to the rates specified under the Tariff Act of 1930.

Import statistics.—Table [43] shows imports of crude naphthalene (solidifying at less than 79° C.) and table [44] of refined naphthalene (solidifying at or above 79° C.) The unit invoice values of imports of refined naphthalene in 1924, 1926, 1927, 1928, and 1935 indicate that the imported product was probably not naphthalene as recorded but one of its derivatives provided for elsewhere in paragraph 27.

Table [45] shows the principal sources of our imports of crude naphthalene in recent years. Germany was the principal source until 1936; the United Kingdom, previously the next most important source, was first in 1936 and 1937. In the last three years appreciable quantities have been received from Poland, Czechoslovakia, and the Soviet Union, hitherto unimportant sources.

Exports are not shown separately; it is doubtful if any naphthalene is exported. Demand in the United States has exceeded domestic production.
