China’s unique Difenacoum pioneer
According to the National Industrial Policy “Regulations on Promoting Industrial Structure Adjustment” withing the “Catalogue for Guiding Industry Restructuring (2005)” that came into effect on December 2, 2005, the manufacture of new rodenticides is prohibited in China.
The only Difenacoum production line in China was based on our Brodifacoum production project which received pre-approval from the authorities in 2004 when the factory was expanded. Unfortunately, as the only applicant in China to submit registration data for Difenacoum, the factory missed the deadline for registration of rodenticide manufactured under the 2005 national industrial policy. Therefore Difenacoum active ingredient is no longer available in China as of December 2005.
Base on the pre-approved Difenacoum manufacturing with environmental impact assessment and safety evaluation qulifications, Siyang Rodenticide Factory has produced some Intermediate (the last stage, C22H20O) for export purpose. The current stock is limited and it is in full compliance with all laws and regulations in China.
