Westwater Resources Supports Office of the United States Trade Representative Decision to Implement Section 301 Tariffs on Natural Graphite

• Modified Section 301 tariffs will implement a new 25% tariff on natural graphite imports from China.
• Section 301 tariffs play a critical role in driving demand for U.S.-produced anode materials.

Westwater Resources, Inc. (NYSE: American: WWR), an energy technology and battery-grade natural graphite company (“Westwater Resources” or “Westwater”), supports the Office of the United States Trade Representative (USTR) decision to proceed with Section 301 tariffs on commodity imports from China, including lithium-ion batteries and natural graphite.

Pursuant to the terms of Section 301, three new natural graphite products from China will be subject to a 25% tariff. Natural graphite is imported in a variety of forms under several Harmonized Tariff Schedule import codes. Tariffs on some forms of graphite, including CSPG (coated natural graphite anode material), already went into effect on June 14, 2024. This new decision by the USTR will go into effect in 2026 and subjects the several new forms of natural graphite to the same 25% tariff.

Jon Jacobs, Westwater’s Chief Commercial Officer, commented, “Westwater has built great momentum in constructing its U.S. natural graphite processing plant and securing offtake deals for the sale of all planned CSPG and Fines production during the initial phase of the Kellyton graphite plant through 2031. We believe the U.S. Section 301 tariffs are a critical and important component in accelerating demand for domestically produced natural graphite.”
