Prosecutors allege that petrochemical firms fixed prices and bid volumes for eight basic chemicals while Middle East tensions swung feedstock costs. Eight current and former executives faced detention hearings and warrants were issued for two. The alleged cartel exceeds 15 trillion won.
A court issued detention warrants early on Sept. 19 for two of eight current and former petrochemical executives suspected of violating the fair trade law. The decision followed hearings that began at 9:20 a.m. the previous day. Those detained include a sales division head at one of the companies.
광고 문의 · 300×250Prosecutors place the conduct between May 2021 and March 2026, roughly five years. The products at issue are eight basic chemicals including polyvinyl chloride, plasticizers, caustic soda and hydrochloric acid, with the indictment alleging advance agreement on the size of price increases and on bid volumes.
Scale defines the case. Prosecutors put the total at more than 15 trillion won, above the 14.2 trillion won refining cartel uncovered in July and described as the largest in their investigative history.
Why now
The background cited repeatedly is naphtha. It is the base feedstock for petrochemicals and reacts sharply to Middle East conditions and oil prices. Competition authorities generally argue that when input costs swing violently, individual firms find unilateral price increases hard to sustain, which raises the incentive to coordinate.
The companies say they were passing through higher input costs in normal pricing. Proving a cartel turns not on parallel price moves themselves but on evidence of prior agreement and information exchange. That is where the court's judgment will fall.
Where it touches industry and household prices
PVC and caustic soda feed into construction materials, piping, packaging, paper and food processing. When basic chemical prices rise, downstream costs follow in sequence and show up in consumer prices with a lag. Damage claims are expected if the findings are confirmed.
The context also includes an industry already restructuring. New Chinese capacity has left commodity grades oversupplied, and Korean producers have been cutting output and reshaping portfolios. The downturn and the cartel allegations are separate matters, but the market treats the case as a variable affecting the pace of consolidation.
This paper notes that detention does not imply guilt. It reflects a judgment on flight risk and evidence tampering; whether a cartel existed will be settled at trial.
