South Korea's Fair Trade Commission (FTC) began reviewing allegations that Daesang (KRX:001680), Sajo Industries (KRX:007160) subsidiary Sajo CPK, Samyang Corp. (KRX:145990), and CJ CheilJedang (KRX:097950) colluded in bid-rigging and price-fixing in the starch-sugar market.
The alleged bid-rigging for starch and starch-based sweetener tenders affected 9.4 billion won in sales between September 2016 and June 2025, the trade watchdog said in a Tuesday release.
It also accused Daesang, Sajo CPK, and Samyang of fixing prices for starch and starch-sugar by-products from August 2017 to October 2025, which affected sales of about 1.55 trillion won, it said.
The FTC imposed a fine of 234.1 billion won on Daesang and 210.3 billion won on Samyang Corp.
Shares of the food companies Daesang and Samyang fell 2%, while shares of the food manufacturer CJ Cheiljedang declined nearly 2% in recent trade.
