South Korean prosecutors raided the offices of three SK hynix Inc. suppliers during a price-fixing investigation.
The targeted companies are Duksan Hi-Metal, MK Electron, and LT Metal.
These firms allegedly colluded on the prices and supply volumes of semiconductor manufacturing materials.
The Seoul Central District Prosecutors' Office conducted the raids.
Investigators are examining whether the suppliers abused their market position.
The probe seeks evidence of executives and employees artificially adjusting prices and quantities.
This action aligns with a broader South Korean crackdown on unfair trade practices and collusion.
All three companies serve as key vendors for SK hynix, a major global memory semiconductor manufacturer.
