On Aug 17 the U.S. International Trade Commission (ITC) voted to institute a
Section 337 investigation into certain transformers and their components. The
action follows a July 16, 2026 petition by U.S. firm AyrEnergy alleging Section
337 violations and seeking a limited exclusion order and cease-and-desist
orders. Named respondents are Zetwerk Manufacturing (India and U.S.), KRYFS
Power Components (India) and Unimacts Global (U.S.).
