South Korea: sugar and flour cartel cases this year cover nearly 15 trillion won in related turnover

Price-fixing cases uncovered this year in South Korea's market for basic food ingredients involve combined related turnover of close to 15 trillion won, according to figures released on September 23 by Yoon Jun-byung, a Democratic Party of Korea member of the National Assembly's Agriculture, Food, Rural Affairs, Oceans and Fisheries Committee.

The cases concern sugar and wheat flour, two inputs that feed into bread, noodles, confectionery, sauces, beverages and most other processed food categories sold in the country. Because both sit at the base of the food chain, coordinated pricing in these markets does not stay contained: it is carried forward into the cost structure of thousands of finished goods and, ultimately, into retail prices.

What the 15 trillion won figure represents

The number is not a penalty total. Under Korean competition law, related turnover is the revenue generated in the affected market over the period of the conduct, and it serves as the calculation base for administrative surcharges. A figure approaching 15 trillion won therefore describes the commercial scale of the markets found to have been distorted, not the amount the companies involved have been ordered to pay.

For analysts, the distinction matters. Final surcharges are set as a share of related turnover after adjustments for aggravating and mitigating factors, so headline exposure and eventual cash outflow can diverge widely. Decisions can also be contested in the courts, which lengthens the gap between the announcement of a case and any settled financial impact on the companies concerned.

Tariff relief and price fixing in the same markets

The political weight of the disclosure comes from the policy backdrop. The government has applied tariff-rate quotas to imported food raw materials as part of its effort to stabilise consumer prices, reducing or removing duties so that processors face lower input costs. The point raised in parliament is that the state has been giving up tariff revenue to hold down food prices in precisely the markets where large food manufacturers have repeatedly been caught coordinating prices.

South Korea buys essentially all of its raw sugar and milling wheat abroad, which makes duty policy on these inputs one of the few direct levers the government holds over processed food costs. Quota-based tariff relief only reaches households if the saving is passed down the chain. Where refining and milling prices are aligned between suppliers, that transmission mechanism is removed and the benefit stops at the manufacturer's margin.

Calls to tighten sanctions

Yoon argued that the repeated detection of cartels among major food companies shows that current sanctions are not working as a deterrent, and that their practical effectiveness needs to be raised. The argument is being made at a moment when food inflation remains politically sensitive and when the state has committed fiscal resources, in the form of forgone customs duties, to easing raw material costs for the same industry.

Any tightening would most likely be debated in terms of the level of surcharges, the conditions attached to tariff-quota access, and the willingness of authorities to pursue individual as well as corporate liability. None of these has been legislated on the basis of this disclosure so far; the committee-level discussion sets the direction rather than the outcome.

What the industry should watch

• Whether surcharge decisions in the sugar and flour cases are followed by damages claims from downstream buyers such as bakeries, noodle makers and confectioners.
• Whether access to tariff-rate quotas on imported raw materials becomes conditional on competition compliance.
• Whether enforcement extends beyond corporate penalties to individual liability for executives involved in price coordination.
• How refiners and millers adjust list pricing and contract terms with industrial buyers while cases remain open.
