“Bromadiolone” and “Brodifacoum” have been included in the “2015 List of Hypertoxic Chemicals,” classified as the highest-level controlled hazardous substances in China.

(Security cameras in the warehouse storing the hypertoxic chemicals Brodifacoum TC and Bromadiolone TC have been connected in real time to the Siyang County Public Security Bureau, as required.)

This is currently the only legally produced stock of Brodifacoum TC and Bromadiolone TC available for export within China; production of these products has been permanently discontinued, and supplies are limited.

Over the past two decades, the following major changes have occurred in global laws and regulations regarding rodenticides (with China and the European Union as the key players):

European Union: the most significant changes include: The EU Biocidal Products Regulation (EU BPR, Regulation No. 528/2012), enacted on September 1, 2013, replaced the Biocidal Products Directive (BPD, Directive 98/8/EC); the Article 95 list published by ECHA (European Chemicals Agency) on September 1, 2019; and the implementation of the Regulation on Classification, Labeling, and Packaging of Chemicals (EU CLP, Regulation (EC) No 1272/2008).
United States: we have noted that Berkshire Hathaway, led by Warren Buffett, officially completed its acquisition of Bell Laboratories on July 31, 2025.
P.R. China: the major changes included a phase-out of the rodenticide industry during the first decade: the promulgation of the National Industrial Policy in 2005; the Catalogue of Projects Prohibited from Land Use issued in 2006; the formal implementation of the National Standard (GB) for Bromadiolone and Brodifacoum in 2007; and the establishment of the Ministry of Industry and Information Technology (MIIT) in 2008. These reforms, policies and regulations eliminated three manufacturers, resulting in the reduction of China’s original five producers of technical rodenticides to just two. Then, over the subsequent decade, the state introduced a series of new policies and revised numerous laws and regulations.
Regulatory Bodies (political system reforms in China have led to a reorganization of regulatory agencies):
In 2018, China underwent institutional reforms that also led to changes in the regulatory bodies overseeing the rodenticide industry. Currently, the administrative departments previously responsible for “technical rodenticides” have been consolidated from multiple ministries and commissions – namely the Institute for the Control of Agrochemicals, Ministry of Agriculture (ICAMA); the Ministry of Environmental Protection (MEP); the National Development and Reform Commission (NDRC); the Ministry of Public Security (MPS); the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ); the Ministry of Industry and Information Technology (MIIT); and the State Administration of Work Safety (SAWS) – into primary three departments: the Ministry of Public Security (MPS); the Ministry of Emergency Management (MEM); and the Ministry of Agriculture and Rural Affairs (MARA).

Major Events at the Siyang Rodenticide Factory Over the Past Two Decades or So:

From 2005 to 2008:, during China’s rodenticide phase-out initiative (GB standards, MIIT designated), we obtained national industrial production certificates for two active ingredient products (Brodifacoum TC and Bromadiolone TC), becoming one of only two legally authorized entities in China.
In 2013, considering that the factory had not produced rodenticide baits for over a decade, the “Pesticide Production License for rodenticide 0.005% RB” issued by the MIIT was formally relinquished to reduce administrative expenses for this project. Nevertheless, we have continued to extend the validity of the registration certificate for this pesticide until it expires in 2023. (the company has completely abandoned the end-user market and focuses exclusively on active ingredients since 2013.)
In 2019, due to the safety distance between the factory and newly constructed residential areas no longer meeting the latest safety regulations and policies, we were compelled to cease production at the original site and began investing in the construction of a new factory. Concurrently, the old plant underwent a series of upgrades in compliance with the new Pesticide Law enacted in 2017, successfully obtaining a “Restricted-Pesticide License” issued by the MARA.
In 2021, the factory ultimately completed its relocation by treating it as a non-production project (Upgrading Storage Facilities for HyperToxic Chemicals Brodifacoum and Bromadiolone), obtaining a “Hazardous Chemicals Permit” issued by MEM and a updated “Restricted Pesticide Permit” issued by MARA.
From 2022 to 2023, due to relocation, our factory withdrew from the pesticide manufacturing industry and only sold inventory products (brodifacoum TC and bromadiolone TC). Therefore, the seven pesticide registration certificates issued by the Ministry of Agriculture listed below will not be renewed upon expiration.
– PD2007323 (Brodifacoum 98% TC), – Valid until September 17, 2022,
– PD20071101 (Brodifacoum 0.5% TK), – Valid until August 18, 2023,
– PD20071102 (Brodifacoum 0.005% RB), – Valid until August 18, 2023,
– PD20070322 (Bromadiolone 98% TC), – Valid until September 17, 2022,
– PD20081024 (Bromadiolone 0.5% TK), – Valid until August 6, 2022,
– PD20081154 (Warfarin 98% TC), – Valid until September 2, 2023,
– PD20083600 (Coumatetralyl 97% TC), – Valid until December 12, 2023.
In June 2025, the Storage Facility for Hypertoxic Chemicals (Brodifacoum TC and Bromadiolone TC) at the new plant site, which had already been approved and licensed by MEM, underwent further upgrades. For example: Hiring qualified security personnel, installing additional cameras to achieve comprehensive, blind-spot-free surveillance, and replacing existing security measures with denser security grilles. It was ultimately accepted by a joint inspection team from the public security departments of Suqian City and Siyang County, in accordance with the Ministry of Public Security’s GA 1002-2012 standard (MPS). It must be noted that the factory warehouse, currently used for storing hypertoxic chemicals (technical ‘brodifacoum and bromadiolone’), has surveillance cameras connected to the county police department for real-time monitoring.
Currently holds two Mandatory Licenses in China for the storage and sale 2 technical-grade rodenticides (Brodifacoum technical material and Bromadiolone technical material):
(1) “Hazardous Chemicals License” by MEM, (for “hypertoxic chemicals” – controlled Brodifacoum TC and Bromadiolone TC), ours will expire on June 23, 2027.
(2) “Restricted Pesticide License” by MARA (for “state-designated sales” – restricted Bromadiolone Active Ingredient and Brodifacoum Active Ingredient), ours will expire on September 14, 2026. (#Latest update: On June 10, 2026, the Siyang Rodenticide Factory successfully renewed its license for restricted-use pesticides, extending its validity through September 14, 2031.)

Frequently Asked Questions (FAQs)

(1) What is the history of anticoagulant rodenticides in China, and how many manufacturers of active ingredients are there?
Over the past 40 years, there were six active ingredients permitted for rodenticide production in China: “Chlorophacinone (only Siyang), Warfarin, Coumatetralyl, Brodifacoum, Bromadiolone and Difenacoum (only Siyang)” with a total of five licensed manufacturing companies were located in: “Siyang county (Jiangsu province), Tianjin Municipality, Shanghai Municipality, Zhangjiakou city (Hebei province), and Xiaolin town, Cixi city (Zhejiang province).” However, with China’s industrial upgrading (2005 National Industrial Policy, the rodenticide project prohibited new land use in 2006, the formal implementation of the rodenticide national standard (GB) in 2007) and regulatory reforms (the establishment of the MIIT in 2008), only two rodenticide active ingredients (Bromadiolone and Brodifacoum) retained production permits, and only two companies retained production qualifications, namely “Siyang” and “Tianjin.” All other active ingredients and manufacturers have been completely phased out, and in accordance with the policies, no new manufacturers or projects will be approved. It should be noted that among the three companies whose active ingredient production qualifications were revoked, two are state-owned enterprises, namely “Shanghai Gaolun Modern Agrochemical Co., Ltd. (under Shanghai Pesticide Research Institute)” and “Zhangjiakou Jinsai Pharmaceutical Co., Ltd.” (formerly Zhangjiakou Rodenticide Plant, the developer of first generation of anticoagulant rodenticides, Warfarin and Coumatetralyl in China).
(2) How many active ingredients are approved for use in rodenticide (anticoagulant) in China now?
If referring to the “Pesticide Registration Certificate” issued by the MARA, there are currently five active ingredients with valid registration status: “Warfarin, Coumatetralyl, Brodifacoum, Bromadiolone, and Flocoumafen.” However, it should be noted that obtaining MARA registration in China does not automatically grant authorization for production and sale. In China, registration and authorization are separate processes: the production and operation of these technical rodenticides require obtaining another two mandatory permits: the “Hazardous Chemicals Permit” and the “Pesticide Production Permit (according to regulations, new approvals have been suspended since 2005).” According to the latest Pesticide Law of 2017, only two active ingredients for rodenticides are currently permitted for production and sale in the Chinese market: Brodifacoum and Bromadiolone; all other active ingredients for rodenticides are illegal.
(3) Which Chinese government agency is responsible for reviewing and approving qualifications for the production of rodenticides and issuing production licenses?
Prior to 2017, the Ministry of Agriculture (specifically, this is the responsibility of ICAMA, which is under the MoA) was solely responsible for pesticide registration. The production of Brodifacoum TC and Bromadiolone TC required two separate production licenses: a hazardous chemicals permit issued by the State Administration of Work Safety (SAWS, now MEM) and a National Industrial Product (Pesticide) Production License issued by the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ). Following the implementation of the new pesticide regulations in 2017, the hazardous chemicals permit is now issued by the new Ministry of Emergency Management (MEM, the former SAWS), and the pesticide license is issued by the new Ministry of Agriculture and Rural Affairs (MARA, the former MOA).
(4) Apart from the two licensing authorities mentioned above (MEM, MARA), who else is responsible for regulating technical-grade rodenticides?
It is the Ministry of Public Security (MPS), which is primarily responsible for regulating the procurement, transportation, and storage of hypertoxic chemicals (including brodifacoum TC and bromadiolone TC). Since the entry into force of Ministry of Public Security Order No. 77 of 2005, it has been explicitly stipulated that the sale and transportation of all highly toxic chemicals (such as brodifacoum TC and bromadiolone TC) must be reported to public security authorities at the county level or above; in 2012, the MPS further promulgated detailed storage requirements, namely the GA 1002-2012 standard.
(5) What are the laws applicable in China regarding the illegal production, storage, sale, and transportation of hypertoxic chemicals (such as the industrial-grade rodenticides “Brodifacoum TC” and “Bromadiolone TC”)?
Article 125 of the Criminal Law of the People’s Republic of China, titled “Illegal Manufacture, Sale, Transportation, or Storage of Hazardous Substances,” applies. Violators shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years; where the circumstances are serious, they shall be sentenced to fixed-term imprisonment of not less than ten years, life imprisonment, or the death penalty.
(6) What is the legally required packaging for exports of Bromadiolone TC and Brodifacoum TC?
We require specially customized steel drums that comply with UN Packaging Group “I” standards. In the past, we often customized UN steel drums with capacities of 73 and 78 liters, suitable for loading 20 kg of Bromadiolone technical material or 25 kg of Brodifacoum technical material. The performance of UN Group “I” steel drums must comply with the requirements of China’s mandatory standard GB-3796 “General Rules for Pesticide Packaging”: stacking test ≥ 3 meters, air-tightness test ≥ 30 k Pa, and hydraulic test ≥ 250 k Pa. An example of the compliant United Nations specification (Brodifacoum TC and Bromadiolone TC: “UN3027, Class: 6.1, PG:I”) packaging mark we have used in the past: “UN 1A2/X32/S/19/CN/C230409/PI:010.” Additionally, custom-made UN steel drums have an export validity period of only 12 months from the date of production.
(7) What are the legal procedures for Brodifacoum TC and Bromadiolone TC prior to export from the port? Specifically, what are the regulatory requirements for transport from the factory warehouse to the customs warehouse (within China’s territory) ?
First, the “Measures for the Purchase and Road Transportation Management of Hypertoxic Chemicals,” promulgated by the Ministry of Public Security (MPS) in 2005, are currently in effect. Specifically, these regulations implement a “Five-Double” Management System: Double-Person Custody (Double Storage/Dual Receivers & Senders); Double Locks (Dual-Lock Storage); Double-Person Requisition / Withdrawal; Double-Person Use; Double Ledgers (Dual Bookkeeping).” And all out of warehouse and ultimate destination must be reported to the Siyang County Public Security Bureau (Public Order Management Division); for road transport, trucks must have a hazardous materials transport license, and port warehouses must also have a hazardous materials storage license. In addition, in accordance with the 2012 Ministry of Public Security regulations on warehousing, the surveillance cameras at warehouses are now connected in real time to the county-level public security bureaus.
(8) What are the shipping methods for legally exporting Brodifacoum TC and bromadiolone TC from China? What legal documents and procedures are required for export?
In China, airlines absolutely do not accept air transport of hypertoxic chemicals (technical Brodifacoum and technical Bromadiolone); for sea transport, almost all shipping companies do not accept less-than-container load (LCL) shipments and only accept full-container load (FCL) shipments. Additionally, in 2020, the General Administration of Customs of China (GAC) issued the “Announcement on Issues Concerning the Inspection and Supervision of the Import and Export of Hazardous Chemicals and Their Packaging,” implementing mandatory inspections for the export of Brodifacoum and Bromadiolone, five certificates are required: (i) the “Certification of Hazardous Classification and Identification;” (ii) the “Performance Inspection Results of Packages for Transportation of Exported Goods;” (iii) the “Inspection Certificate for Export of Dangerous Goods Packaging;” (iv) the “Pesticide Export Release Certificate;” and (v) the “Customs Clearance Certificate for Commodity Inspection” (required starting in 2022).
(8) What is the correct tariff code for technical rodenticide? (HS Codes: “380899” or “293220”?)
There is no doubt that China’s import and export commodity codes match the “Harmonized System” (HS) codes established by the “World Customs Organization” (WCO), but China has further subdivided the internationally accepted 6-digit codes into 10-digit codes. The export tariff codes for pesticides in China are legally mandated, based on the “Catalogue of the People’s Republic of China for the Administration of the Import and Export of Pesticides (latest 2022 edition).” This directory is commonly referred to as the “Chinese Export Pesticide Customs Code.” The tariff code for pesticide export code #640 Brodifacoum, “2932209011,” and the tariff code for pesticide export code #645 Bromadiolone, “2932209013.” In addition, the code #1235 in the export pesticide directory refers to “Retail-packaged Rodenticides (Ready-to-use Bait),” with a tariff number of 3808991090; code #1237 refers to “Non-retail-packaged Rodenticides (Ready-to-use Bait),” with a tariff number of 3808999090. In any case, technical rodenticides (pure brodifacoum TC and bromadiolone TC) must under no circumstances be incorrectly classified under the same tariff code as rodenticide baits (0.005%).
(9) What is the minimum order quantity (MOQ) for exporting Bromadiolone TC and Brodifacoum TC?
Under the latest national regulatory policies effective in 2026, extremely hazardous technical-grade rodenticides may no longer be sold as raw materials for pesticides. Only diluted, low-concentration 0.5% concentrates may be used as raw materials for rodenticides, which is consistent with regulations in other countries worldwide. At the same time, our factory’s export operations require special approval from MARA (Department of Agricultural Crops/Pesticide Management Division) in addition to that from ICAMA. Therefore, we currently only accept one-time clearance purchases from manufacturers – both domestic and international – that hold valid qualifications. Specifically, the minimum order quantity (MOQ) for both Brodifacoum TC and Bromadiolone TC is 1,000 kg.
(10) Payment Methods and Delivery Times (Estimated Time of Departure/Expected Time of Sailing)？
Over the past 20 years of export operations, the factory has only accepted T/T in advanced. Typically, a 50% T/T as deposit, with 30% T/T when the goods are ready for shipment (after all legal documents have been completed); and the remaining 20% T/T against the copy of the bill of lading. In the past, our delivery times were the same as those for ordinary (non-highly toxic) pesticides – all within 90 days. However, since the export of technical-grade rodenticides now requires a separate national-level approval (Department of Pesticide Management, MARA), neither the timeline nor the outcome can be predicted. Therefore, starting in 2026, our delivery time will be within 90 days from the date ICAMA issues the pesticide export certificate; we aim to ship the goods (shipment from port) within 180 days of receiving the deposit.

Latest updated:

On December 27, 2025, China promulgated the Law on the Safety Management of Hazardous Chemicals. This law officially took effect on May 1, 2026, replacing the previous Regulations on the Management of Hazardous Chemicals. It marks a new legal phase in China’s hazardous chemical safety management, significantly upgrading regulatory requirements and particularly strengthening controls over key categories such as hypertoxic chemicals (brodifacoum TC, bromadiolone TC).
(i) On March 19, 2026, the General Office of the Ministry of Agriculture and Rural Affairs issued the “Notice on the Concentrated Crackdown on the Illegal Production, Operation, and Use of Prohibited and Restricted Pesticides.” (https://www.moa.gov.cn/ztzl/2026ncgjxs/gzbs_30197/202604/t20260401_6482858.htm).

On June 29, 2026, Chinese authorities revoked the production license of a rodenticide factory located in Shenyang (Liaoning Province); in other words, the company was permanently shut down and prohibited from engaging in any pesticide-related activities. Additionally, a representative of the company has already been sentenced to 10 years in prison in accordance with the law, while two other key sales personnel from the company were each sentenced to 5 years in prison(see Question 5 in the FAQs).
(https://www.enongzi.com/news/details?id=5aeb110f-3b10-4dce-b270-6d9624fbec08)
On July 10, 2026, Seven government agencies, including the Ministry of Agriculture and Rural Affairs (MARA) and the Ministry of Public Security (MPS), have issued directives to further regulate the production, distribution, and use of pesticides and veterinary drugs. The comprehensive enforcement campaign will run from July 2026 through the end of March 2027. It will involve a full-scale, end-to-end crackdown in accordance with the law on the production, distribution, online sales, and use of prohibited and restricted pesticides and veterinary drugs, and will strictly crack down on the illegal production, distribution, and use of such substances.
