The most active coumarin-based anticoagulant rodenticide ideal to keep larger pests such as possum at bay.


This is the most sought after 2nd-generation anticoagulant rodenticide with a simple 4-step synthesis coumarin derivative.


This has the same synthesis steps as Brodifacoum, original absent actives ‘Br’, it is safer for ecology especially birds.


On February 8, 2017, China State Council approved the amendment to the “Regulation on the Administration of Pesticides” – Decree No. 677, while repealing Decree No. 326 of 2001. This is the third amendment since the first regulation, Decree No. 216 was enacted the year 1997.

On June 21, 2017,  Ministry of Agriculture (MOA) issued “The Measures for the Administration of the Pesticide Registration (2017)” under the State Decree No. 677, it shall come into force on August 1, 2017. – MOA Order No.3/2017.

On August 31, 2017, China MOA issued Proclamation No. 2567 under the latest 2017 Food Safety Law, the “List of Restricted Use Pesticides (2017)” including 32 pesticides, it will come into force as of November 1, 2017.


The current 6 valid registrations of rodenticide active ingredients in China MOA (Flocoumafen, Sodium Diphacinone, Warfarin, Coumatetralyl, Bromadiolone, Brodifacoum) have been included into the “List of Restricted Pesticides” of year 2017.  All of them will subject to production at the traceable ‘designated site’ and designation marketing management such as ID-based purchase and limited retailers, etc.

In fact, with the exception of the national Brodifacoum and Bromadiolone, the production of other 4 registered actives have never been approved as ‘designated site’ by MIIT (Ministry of Industry and Information Technology) and is therefore no meaning in the above list.


In the last two decades, several companies have registered various rodenticides in MOA, but the MIIT has so far approved the industrial synthesis of 2 rodenticide active ingredients, which are, Brodifacoum and Bromadiolone, at only 2 designated sites under the safety laws and environmental regulations. According to the Article 40 of 2017 Pesticide Registration Regulation, all MOA registrations without production designated will be invalid with effect on August 1, 2019.

This is similar to the change from BPD (Directive 98/8/EC) to BPR (EU 528/2012) and the Article 95 list which is enforced in the EU countries. This is always known as ‘designated site’ in China, a direct translation based on the Chinese language.


Siyang Rodenticide Factory was established in 1985 as a state designated rodenticide production unit approved by the former Ministry of Chemical Industry.

Siyang Rodenticide Factory is currently a designated technical pesticide manufacturer approved by MIIT (the former Ministry of Chemical Industry).

Siyang Rodenticide Factory is mainly supplying Brodifacoum Technical, Bromadiolone Technical and the Intermediate of Difenacoum.


In 2005, Siyang Rodenticide Factory participated in the review meeting for Chinese National Rodenticides held by the Institute Control of Agrochemicals, MOA. It’s the final conclusion on China’s rodenticide under the National Industrial Policy.

  • In 2006, AQSIQ and SAC jointly enacted China’s National Standard – GB (GuoBiao) for Bromadiolone TC (GB 20678-2006) and Brodifacoum TC (GB 20690-2006).

  • In 2008, Siyang Rodenticide Factory was issued the National Industrial Production Permit by AQSIQ for MOA registrations of Brodifacoum and Bromadiolone.

  • In 2013, Siyang Rodenticide Factory obtained the renewed National Industrial Production Permit of Brodifacoum and Bromadiolone with the License No. XK13-003-00347.

  • In 2019, Siyang Rodenticide Factory was officially issued the New Pesticide License (Restricted Class) in accordance with 2017 China’s Pesticide Regulations with the Unique Pesticide No. (SU) 32000010534.
