Japanese customs authorities have confiscated 36,000 cans of Freon 12 CFC gas, banned in Japan for harming the ozone layer, that were illegally imported from China, Kyodo News reported, citing sources "close to the case". The officials have been questioning an automobile parts retailer from the Moji district of Kitakyushu, a port city in southern Japan, who is suspected of importing the gas by filing false customs papers, Kyodo News said.
