Mandatory License as ‘Registered Pesticides’

(AQSIQ License to manufacture rodenticides – only 2 licensed in China)

  • “Designated-site Rodenticide,” a direct translation from Mandarin, the legal rodenticide in pesticide application, meaning that the active ingredient of the rodenticide produced in China has full qualifications status, it is approved by three ministries:
    (1) registration of rodenticides as pesticides with MOA, the Ministry of Agriculture (now MARD, the Ministry of Agriculture and Rural Development) was required under the pesticide regulations since 1997;
    (2) environmental and safety evaluations of pesticide designated producers were conducted by NDRC, the National Development and Reform Commission (succeeded by MIIT, the Ministry of Industry and Information Technology from 2008 onwards); and
    (3) due to the implementation of mandatory national standards from 2007 onwards, in contrast to other pesticides, the production was subject to a separate authorization license from AQSIQ, the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China.
  • The AQSIQ of China finally authorised the 2 sites designated by MIIT to produce 2 active ingredients of rodenticides with national standards – Brodifacoum and Bromadiolone. (Attached Pesticide Production License)
2015 – National legislation and regulatory rules
  • Regulation on Pesticide Administration (first in 1997, then 2001 and now 2017)
    On Feb. 8, 2017, the State Council of China approved an amendment to the “Regulation on the Administration of Pesticides” – known as the State Decree No. 677, coinciding with repeal of the 2001 State Decree No. 326.

Siyang Rodenticide Factory – (38th Year)

Siyang Rodenticide Factory, as the name implies, is a professional rodenticide manufacturing plant located in Siyang County, China. It was established in March 1985 as a collectively owned enterprise.

Siyang Rodenticide Factory is the pioneer of rodenticides in China and has been involved in the development of a total of six anticoagulant rodenticides in the past decades, “Chlorophacinone, Warfarin, Coumatetralyl, Bromadiolone, Brodifacoum and Difenacoum.”

Under China’s latest regulatory reform, Siyang Rodenticide Factory is now defined as a “Restricted Pesticide Site designated by the MOA” for supply of  Technical Bromadiolone and Brodifacoum.

Reforms of rodenticide administration

In 2005, Siyang Rodenticide Factory participated in the Review Meeting of Rodenticides in China held by the ICAMA (Institute for the Control of Agrochemicals, MOA): Brodifacoum and Bromadiolone were adopted as official pesticides in China.

In 2006, China SAC and AQSIQ (General Administration of Quality Supervision, Inspection and Quarantine of China) jointly enacted national standards for Brodifacoum and Bromadiolone, which came into effect in 2007.

  • In 2008, the AQSIQ officially authorized and issued the “Manufacturing Permit of National Industrial Product” to the Siyang Rodenticide Factory for national standards Brodifacoum and Bromadiolone. And only 2 manufacturers licensed in China at the production authorisation deadline.

  • In 2013, Siyang Rodenticide Factory obtained a five-year renewal of the “AQSIQ authorisation permit” for the production of Technical Brodifacoum and Brodifacoum, as well as the processing of 0.5% TK (the mandatory national standard for concentrates in China was set at 0.5%).

  • In 2018, the AQSIQ was merged with the newly created State Administration for Market Regulation. According to the new pesticide laws and regulations in 2017, Siyang Rodenticide Factory was granted a new state pesticide license (restricted) by the MOA in 2019, No. (SU) 32000010534.

  • In 2021, the extremely toxic chemical storage facility at the new site of Siyang Rodenticide Factory first passed the security permit of MEM, then the warehouse was relocated, and finally the new plant again passed the inspection of MOA’s Restricted Pesticide Site and was issued a new permit (SU) 32000013199.
