U.S. Department of Commerce Issues Final Determination in Chinese Graphite Anti-Dumping Investigation

The U.S. Department of Commerce has issued its final determination in anti-dumping and countervailing duty investigations against Chinese graphite-based anode materials, significantly increasing trade barriers for Chinese imports. The DOC raised countervailing duties from 11.58% to 66.68% while maintaining anti-dumping duties at 93.5%, bringing total tariffs and penalties on Chinese natural graphite anode materials to approximately 220%. This includes existing IEEPA tariffs (10%), Section 301 tariffs (25%), Section 232 tariffs (25%), along with the new DOC duties.

The determination follows a year-long investigation into alleged subsidization and unfair pricing practices by Chinese producers. The ruling remains subject to a final affirmative injury determination by the U.S. International Trade Commission expected in March 2026. If confirmed, these duties will remain in effect for a minimum of five years under U.S. trade law.

For domestic graphite producers like Westwater Resources, this regulatory environment creates significant competitive advantages. The company is developing the Kellyton Graphite Processing Plant in Alabama and owns the Coosa Graphite Deposit, described as the largest and most advanced natural flake graphite deposit in the contiguous United States. The trade measures are expected to increase demand for U.S.-produced natural graphite anode materials across lithium-ion battery markets including electric vehicles, energy storage systems, and defense applications.

This development reflects broader U.S. strategic initiatives to reduce dependence on Chinese critical mineral supplies and build domestic battery supply chain capabilities. The substantial tariff burden on Chinese graphite imports creates a protected market environment that could accelerate development of domestic graphite resources and processing capabilities, particularly as demand for battery materials continues to grow with electric vehicle adoption and energy storage deployment.
