US ITC Launches 337 Investigation into Cylindrical Batteries Targeting EVE Energy and Nine Others
The US International Trade Commission announced on August 20, 2026, that it had launched a Section 337 investigation into certain secondary cylindrical batteries, battery components, and products containing them. The probe, initiated at the request of South Korean battery maker LG Energy Solution, covers 10 entities, including Chinese battery producer EVE Energy and two of its US subsidiaries in Ohio and California. EVE Energy ranks as China's fifth-largest battery manufacturer. German, Japanese, and Chinese power-tool makers that use the cells are also named respondents. Section 337 proceedings serve as the primary US mechanism for resolving intellectual property disputes and a common non-tariff trade barrier.

The investigation was initiated by South Korean battery company LG Energy Solution. The 10 entities under investigation include Chinese battery maker EVE Energy and two of its subsidiaries located in the US states of Ohio and California.
EVE Energy is China's fifth-largest battery producer. In addition to EVE Energy and its subsidiaries, downstream companies including Germany's Bosch, Japan's HiKOKI, and Chinese trader Quanfeng have also been named as respondents. These companies were included in the probe because they purchase the relevant battery cells to assemble power tools and export the finished units for sale in the US market. Section 337 investigations are one of the primary mechanisms for resolving intellectual property disputes in the US and are a commonly used non-tariff trade barrier.
