USITC Institutes Section 337 Investigation of Certain Transformers and Components Thereof

The U.S. International Trade Commission (Commission or USITC) voted to institute an investigation of certain transformers and components thereof. The products at issue in the investigation are described in the Commission's notice of investigation.

The investigation is based on a complaint filed on behalf of Ayr Energy, Inc. of Mountain View, California, on July 16, 2026. The complaint alleges violations of section 337 of the Tariff Act of 1930 based upon the importation into the United States, the sale for importation, and/or the sale within the United States after importation of certain transformers and components thereof by reason of misappropriation of trade secrets, false advertising, unfair competition, trademark infringement, false designation of origin, and common law trademark infringement. The complainant requests that the USITC issue a limited exclusion order and cease and desist orders.

The USITC has identified the following respondents in this investigation:

• Zetwerk Manufacturing Businesses Private Limited, Bangalore, India
• Zetwerk Manufacturing USA Inc., San Francisco, California
• KRYFS Power Components Ltd., Mumbai, India
• Unimacts Global, LLC, Lexington, Massachusetts

By instituting this investigation (337-TA-1517), the USITC has not yet made any decision on the merits of the case. The USITC's Chief Administrative Law Judge will assign the case to one of the USITC's administrative law judges (ALJ), who will schedule and hold an evidentiary hearing. The ALJ will make an initial determination as to whether there is a violation of section 337; that initial determination is subject to review by the Commission.

The USITC will make a final determination in the investigation at the earliest practicable time. Within 45 days after institution of the investigation, the USITC will set a target date for completing the investigation. USITC remedial orders in section 337 cases are effective when issued and become final 60 days after issuance unless disapproved for policy reasons by the U.S. Trade Representative within that 60-day period.
