# USITC Investigates Imported Computing Power Systems

On October 9, 2026, the U.S. International Trade Commission instituted Section 337 investigation 337-TA-1526 into imported vertical power delivery systems, components, and computing systems containing them, following a complaint by Vicor Corporation. The investigation has not determined whether infringement occurred. Vicor is seeking a limited exclusion order and cease-and-desist orders against the named respondents, which could affect imports and supply chains for businesses using their products. The USITC expects to set a target completion date within 45 days of instituting the investigation—approximately November 23, 2026, or 44 days from October 10.

- Companies sourcing the covered systems or components from the respondents should assess product and supplier exposure and identify potential sourcing alternatives; the requested orders are not yet findings or restrictions.
- The respondents are Delta Electronics, Infineon Technologies, Monolithic Power Systems, and Hon Hai Precision Industry (Foxconn). Procurement teams buying computing systems containing the investigated products may also face indirect supply-chain exposure.
- The USITC’s forthcoming target completion date will provide a procedural milestone for suppliers and buyers planning around the investigation.
