State-designated Site

In April 2003, with approval under document S.J.F. [2003] No. 108 issued by the Siyang County Development Planning Bureau, 10 mu (6,667 ㎡) of land located in the Siyang Economic Development Zone was purchased for capacity expansion. The expanded factory was completed in 2004 and successfully passed the ‘‘designated-site’’ audit for technical pesticide production by NDRC (National Development and Reform Commission), and began production in August. It is located in the east part of the development zone at the intersection of Songhuajiang Road and Beijing East Road.

Rodenticide synthesis plant

The factory covers an area of 10 mu, with the production workshop accounting for 1900 ㎡ and the hazardous chemicals storage area accounting for another 800 ㎡. The main manufacturing facilities feature 1000-2000-liter reaction kettles, as well as vacuum pumps, centrifuges, drying equipment and other equipment. Laboratory apparatuses include a Shimadzu HPLC (LC-20AT SPD-20A), electronic balances, nano-gram analytical balances, pH meters, digital melting point apparatuses, moisture determination equipment, etc.

Health, Safety, Security, Environment

Siyang Rodenticide Factory possesses complete auxiliary facilities, advanced manufacturing capabilities, strict production safety management and comprehensive environmental, health and security measures. The factory passed the ISO9001 quality management system in 2005 and the safety permit for hazardous chemicals from the SAWS in 2006. The environmental and safety evaluation of the production site passed the inspection in 2009 and was approved as a designated national pesticide production site by the Department of Raw Materials of the MIIT.

The safety permit was issued by the newly reorganized MEM after the relocation was completed in 2021. The plant’s monitoring and perimeter intrusion alarm system is currently networked with the Public Security Bureau in accordance with regulations.

Brodifacoum TC – 100% the highest quality in the world

The factory secured approval for self-export on June 1, 2006, thereby putting itself on the global map. In the past ten years or so, our overseas clients have used certified German reference samples to analyze our products, and the purity of Brodifacoum was all well over 98%, compared with our own extracted standard samples, the analytical results were about 0.1-0.3% different, it should be the best quality in the world.
