South Korea Extends Hanwha Antitrust Limits to 2029 Over 60% Naval Share Risk

Context In 2023 Hanwha completed the purchase of Daewoo Shipbuilding & Marine Engineering (DSME), merging a major shipyard with its own defense component businesses. The Korea Fair Trade Commission (FTC) imposed conditions to prevent market abuse, focusing on pricing, information sharing, and protection of competitors’ trade secrets. After a three‑year review, the FTC concluded that the original concerns persist.

Key Facts - The FTC officially extended the antitrust measures for an additional three years, setting the new deadline at May 2 2029. - Regulators warned that the combined entity could exceed a 60% share of the market for surface vessels and submarines, a threshold that signals potential monopoly power. - Restrictions remain on eight categories of ship‑component supplies, including pricing and refusal of technical data requests. - Two curbs—on ship IFF (identification‑friend‑or‑foe) systems and integrated machinery control systems—were lifted because new competitors have entered those niches.

What It Means The extension signals that the FTC believes Hanwha’s market influence remains unchecked despite the passage of time. By keeping pricing and information‑sharing bans in place, the commission aims to preserve fair competition for other Korean shipbuilders and foreign bidders. The removal of limits on IFF and machinery control reflects a modest diversification of suppliers, suggesting those markets are less vulnerable to dominance.

Hanwha continues to pursue growth abroad, notably through stakes in Austal and the acquisition of Philly Shipyard in the United States. International expansion could intensify scrutiny if the company leverages its domestic market power to secure overseas contracts.

Looking ahead, the FTC will conduct another review before the 2029 deadline and may add up to two more years of restrictions if dominance persists. Stakeholders should monitor Hanwha’s global deals and the emergence of new competitors in the naval component space.
