Japan has announced that it will accept applications for manufacture or import of new chemicals meeting their small quantity criteria, but these applications must be filed during a single one-week period from February 28th to March 7th, 2012. This is in accordance with Japan's Chemical Substance Examination and Manufacturing Control law. For readers of Japanese, more information is available on the Environmental agency website.
The announcement was made by the Japanese Ministry of Economy, Trade, and Industry; the Ministry of Health, Labor, and Welfare; and the Ministry of the Environment. The application requirement applies to annual quantities of 1 to 10 metric tonnes and for only chemicals that are new to Japan (existing chemicals in Japan are not included in the requirement).
This annual event has been occurring for the last 8 years, with the number of applications growing from only about 100 in 2004 up to over 1000 by 2010.
