The following is the complete timeline and tax rates for each stage of the US anti-dumping and anti subsidy (anti-dumping) investigation against China's active negative electrode materials (graphite negative electrode), as well as the latest results as of March 12, 2026.
In December 2024, the American Association of Activated Anode Material Manufacturers (AAAMP) submitted a complaint accusing China of dumping and subsidizing graphite anodes, hindering the establishment of domestic industries in the United States.
On January 7, 2025, the US Department of Commerce officially initiated a anti-dumping (AD) and countervailing (CVD) investigation into active negative electrode materials from China.
Preliminary stage (May July 2025)
1. Preliminary ruling on countervailing measures (May 20, 2023)
The US Department of Commerce determines the existence of subsidies and imposes temporary countervailing duties:
Individual tax rate enterprises: 712.03% -721.03%
Unified tax rate for other Chinese exporters: 6.55%
2. Preliminary anti-dumping determination (July 17, 2025)
The US Department of Commerce has determined the existence of dumping and imposed temporary anti-dumping duties:
Individual tax rate for enterprises: 93.50%.
Unified tax rate for other Chinese exporters: 102.72%.
Final arbitration stage (February 2026.2)
On February 11, 2026, the US Department of Commerce issued a final anti-dumping ruling, confirming the establishment of dumping and subsidies
1. Anti dumping duties (AD):
Individual tax rate for enterprises: 93.50% (maintaining initial ruling).
Unified tax rate for other Chinese exporters: 102.72% (maintaining preliminary determination).
2. Countervailing Duty (CVD):
National unified tax rate: 66.82% -66.86%.
Comprehensive tax rate (AD+CVD):
Individual tax rate for enterprises: 93.50%+66.82%/66.86% ≈ 160.32% -160.36%.
The unified tax rate for other Chinese exporters is 102.72%+66.82%/66.86% ≈ 169.54% -169.58%.
Final result (March 12, 2026)
On March 12, 2026, the US International Trade Commission (ITC) finally voted against it, determining that Chinese imports did not substantially harm the establishment of US domestic industries, therefore anti-dumping duties (AD) and countervailing duties (CVD) have not taken effect.
