The only pre-approved Difenacoum Production in China

  • The only Difenacoum production line in China was pre-approved by the competent authority when we expanded the plant in 2004. As the only applicant to submit the Difenacoum registration dossier, Siyang Rodenticide Factory failed to pass ICAMA registration before the deadline for rodenticide manufacturing industry, that is, the 2005 National Industrial Policy.
  • According to the National Industrial Policy of the “Regulations on Promoting Industrial Structure Adjustment” with the “Catalogue for Guiding Industry Restructuring (2005)” that came into effect on December 2, 2005, China has banned any new rodenticide manufacturers and production projects.
  • By the pre-approved Difenacoum manufacturing with qualified Environmental impact assessment and Safety evaluation, Siyang Rodenticide Factory used to produced some fixed Difenacoum intermediate (the last stage, C22H20O) for export purpose. The current stock is limited and fully complies all regulations in China.
