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].
