Commerce Department's Final Determination Reshapes Chinese Graphite Tariff Landscape at 220 Percent

The US Department of Commerce has concluded its investigation into unfair trade practices by Chinese graphite producers, delivering a determination that sends shockwaves through the global battery supply chain. On February 11, 2026, Commerce issued its final determination, substantially escalating trade barriers on Chinese natural graphite anode materials to historic levels. The cumulative tariff burden now reaches approximately 220 percent—a dramatic jump that industry observers say will fundamentally restructure sourcing decisions for battery manufacturers worldwide.

Dramatic Escalation in Countervailing Duties Marks Key Shift

The Commerce Department’s final determination radically altered the tariff structure compared to its preliminary findings from 2025. While anti-dumping duties remain unchanged at 93.5 percent, countervailing duties skyrocketed from the preliminary 11.58 percent to a final 66.68 percent. When combined with existing protections—including a 10 percent duty under the International Emergency Economic Powers Act, 25 percent Section 301 tariffs, and 25 percent Section 232 tariffs—the total impact becomes staggering.

Westwater Resources, a US-based natural graphite developer, detailed the breakdown in its analysis: the determination now encompasses roughly 220.18 percent in cumulative tariff burden. The company emphasized that this final determination confirms what it has long argued: Chinese producers systematically violated anti-dumping rules through artificially depressed pricing and state-backed subsidies.

ITC’s Pending Determination to Seal Long-Term Trade Framework

The commerce determination remains technically subject to one final hurdle: the US International Trade Commission must issue an affirmative injury determination expected in March 2026. Should the ITC’s determination align with Commerce’s findings, these duties will lock into place for a minimum of five years under US trade law, establishing a quasi-permanent barrier to Chinese graphite imports.

The timeline compressed remarkably. American Active Anode Material Producers (AAAMP)—a coalition representing North American graphite producers—filed its initial petition in December 2024. The group sought protection levels as high as 920 percent, claiming Chinese state subsidies and artificially suppressed pricing were obliterating efforts to develop a domestic graphite anode industry.

Graphite Supply Chain Faces Historic Realignment

The determination covers both natural and synthetic graphite, as well as graphite contained within finished lithium-ion batteries—a crucial distinction since graphite comprises the largest component in lithium-ion battery anodes used across electric vehicles, energy storage systems, and defense applications.

The strategic importance of this determination cannot be overstated. According to the US Geological Survey, the United States produces zero domestic natural graphite and remains entirely dependent on imports. In 2024, every unit of domestic graphite demand came through foreign supply channels. That dependency now faces potential disruption as manufacturers weigh the 220 percent tariff burden against developing alternative sources.

US Producers Position to Capture Demand Surge

Industry analysts suggest the determination opens unprecedented opportunities for domestic producers. Westwater Resources controls the Coosa Graphite Deposit, described as the largest and most advanced natural flake graphite deposit in the contiguous United States. The company is simultaneously developing the Kellyton graphite processing plant in Alabama, positioning itself to capture demand formerly directed toward Chinese suppliers.

The determination essentially signals that policymakers intend to subsidize the emergence of a competitive North American graphite anode industry—a strategic choice reflecting concerns about supply chain vulnerability in critical battery technology. As the ITC’s anticipated determination approaches, supply chain managers across the EV and energy storage sectors face significant repricing decisions that could accelerate adoption of US-sourced graphite materials across commercial and defense applications.
