Commerce's Final Determination on Chinese Graphite Imposes Record Tariff Levels

The US Department of Commerce has delivered a sweeping determination that fundamentally reshapes trade policy on battery-grade graphite materials from China. Released on February 11, 2026, this final determination significantly increases tariff burdens on Chinese graphite anode imports through a combination of countervailing and anti-dumping measures that, when stacked with existing duties, now total approximately 220 percent.

The determination raises countervailing duties on Chinese natural graphite anode material to 66.68 percent while maintaining anti-dumping duties at 93.5 percent. This represents a substantial increase from the preliminary findings issued in 2025, when countervailing duties stood at just 11.58 percent. The anti-dumping component remained unchanged, but the countervailing duty escalation demonstrates Commerce’s stronger stance in the final determination process.

Breaking Down the Record Tariff Structure

According to Westwater Resources (NYSE:WWR), a US-based developer of battery-grade natural graphite, the cumulative tariff burden now encompasses multiple layers of protection. The structure includes a 10 percent duty under the International Emergency Economic Powers Act, 25 percent Section 301 tariffs, 25 percent Section 232 tariffs, 66.68 percent countervailing duties, and 93.5 percent anti-dumping duties—totaling roughly 220.18 percent.

This determination reflects Commerce’s conclusion that Chinese producers engaged in unfair pricing and subsidy practices harming the US market. The investigation traces back to a December 2024 petition filed by American Active Anode Material Producers (AAAMP), a coalition of North American graphite producers who argued that Chinese state subsidies and artificially depressed pricing were systematically undermining efforts to establish a domestic graphite anode industry.

What Triggered This Trade Determination?

The investigation scope covers active anode materials including natural and synthetic graphite, as well as graphite contained within finished lithium-ion batteries. Graphite serves as the largest component in lithium-ion battery anodes used across electric vehicles, energy storage systems, and defense applications—typically composed of a blend of natural and synthetic materials.

The US Geological Survey has documented that the United States does not mine natural graphite domestically and remains entirely dependent on imports to meet demand. Throughout 2024, all domestic graphite requirements were satisfied through foreign supply chains, creating significant vulnerability in the battery supply chain.

Final Determination Now Awaits ITC Affirmation

This determination remains subject to a final affirmative injury determination by the US International Trade Commission, with a decision expected in March 2026. Should the ITC affirm injury, the duties will remain enforceable for a minimum of five years under US trade law, providing sustained protection for domestic producers.

Market Implications of This Determination

Industry analysts suggest the expanded trade measures from this determination could substantially shift demand toward US-produced natural graphite anode materials, particularly across lithium-ion battery markets serving electric vehicles, energy storage, and defense sectors. Westwater Resources is positioning itself to capture this opportunity, developing the Kellyton graphite processing plant in Alabama while controlling the Coosa Graphite Deposit, characterized as the largest and most advanced natural flake graphite deposit in the contiguous United States.

The determination effectively creates unprecedented tariff protection that could catalyze investment in domestic graphite production capabilities, marking a significant shift in US strategy toward building resilient battery supply chains independent of Chinese suppliers.
