  Above all, we are going to set up another facility for Sodium Trichloro Pyridinol. At the same time, our company has the capacity of O,O-diethyl thio phosphoryl chloride(DETCL) as 30,000 metric tons annually. As one of the largest production suppliers on DETCL in China, the product quality has already ranked the advanced home leading level.

The above two mentioned products are the most important raw materials of CHLORPYRIFOS. This obviously decreased the possibility for purchasing instable raw materials on quality.
