Overview of Final Determinations
On April 1, 2025, the US Department of Commerce announced its final determinations in the anti-dumping (AD) and countervailing duty (CVD) investigations regarding imported 2,4-Dichlorophenoxyacetic Acid (2,4-D) from China and India.
The rulings determined:
- Dumping margins for Chinese products: 127.71% (cash deposit rate adjusted for subsidies: 126.58%)
- Dumping margins for Indian products: 6.10% to 25.85% (cash deposit rates: 3.18% to 20.62%)
- Countervailing duties for China:
- Shandong Rainbow Agrosciences Co., Ltd.: 169.63%
- Jiangxi Tianyu Chemical Co., Ltd. and other producers/exporters: 26.50%
- Countervailing duties for India: 5.29% to 6.32%
The affected products fall under US Customs code 2918.99.2010.

Export Perspectives and Market Impact
China and India are among the largest global exporters of 2,4-D, supplying major markets including the US, Brazil, and Australia. These final rulings are expected to significantly restrict Chinese 2,4-D exports to the US, impacting companies like Shandong Rainbow Agrosciences and Jiangxi Tianyu Chemical.
India, with lower imposed duty rates, may gain short-term competitive advantage in the US market but faces growing regulatory scrutiny.
Top Competitor Analysis
Key global producers in the 2,4-D market include:
- Corteva Agriscience (USA)
- Nufarm (Australia)
- Shandong Rainbow Agrosciences (China)
- UPL Ltd. (India)
The duty rulings may benefit Corteva and Nufarm by reducing low-cost competition in the US domestic herbicide market.
Company Dynamics and Financial Considerations
Shandong Rainbow and Jiangxi Tianyu are likely to face significant revenue pressures due to restricted US market access. Companies are expected to shift focus to Southeast Asia and Latin America to mitigate potential losses.
Meanwhile, US-based producers could see improved margins and higher market shares in the domestic herbicide sector throughout 2025.
