China's Ministry of Commerce announced Wednesday that the span of the anti-dumping investigation of an imported chemical product, chloroepoxy propane, will be extended by six months.

The ministry said the extension of investigation period was due to "specialty and complexity of the case." The investigation involves imports from Russia, Japan, the Republic of Korea, and the United States.

The ministry announced on December 28 last year that it would began investigating to determine whether those four countries have "dumped" the chemical on China's market.
