Gumi City in North Gyeongsang Province set the benchmark for Korean regional semiconductor competition with a ₩1,000 per pyeong land lease rate for new fab construction — the lowest industrial land price offered by any Korean municipality for chip production facilities. The announcement positions Gumi as the value leader in a national scramble for foundry and memory capital that intensified after the U.S. CHIPS Act and IRA reallocated $52 billion in North American fab subsidies.

The rate applies to qualified semiconductor manufacturing projects on designated industrial land within Gumi National Industrial Complex. For context, a standard 300mm wafer fab occupies roughly 100,000 to 150,000 pyeong of land — Gumi's pricing would deliver ₩100 million to ₩150 million in annual lease savings versus regional competitors charging ₩3,000 to ₩5,000 per pyeong. The city did not disclose minimum capital expenditure thresholds or employment requirements, but prior Gyeongsang Province incentive packages have required ₩500 billion minimum investment and 300+ local hires within three years of groundbreaking.

This matters because Korean chipmakers face a capital allocation decision that wasn't optional eighteen months ago. Samsung and SK Hynix both expanded U.S. fab presence in 2023-2024 to access IRA tax credits — Samsung's $17 billion Taylor, Texas project and SK's $15 billion Purdue complex — but both companies now recalibrate as Washington signals subsidy payment delays and imposes Buy American restrictions on equipment procurement. Domestic fab expansion becomes attractive again, but only if land and utility costs compensate for lost U.S. incentives. Gumi's move is the opening bid in what will be a provincial land-price war.

The regional competition is not symbolic. Gyeonggi Province — home to Samsung's Pyeongtaek campus — already offers ₩2,500 per pyeong rates in select zones, and Chungcheong provinces have floated similar packages. Gumi's 60% discount to Gyeonggi pricing forces neighboring cities to either match or differentiate on infrastructure. North Gyeongsang has prioritized power grid upgrades: the province committed ₩800 billion to substation expansion in Q4 2024, targeting 500 MW of additional industrial capacity by late 2026. For fabs consuming 100-150 MW at full operation, reliable power matters more than land cost — but land cost gets the headlines.

Allocators should track three developments. First, whether Samsung or SK Hynix file land acquisition permits in Gumi within 90 days — neither company has publicly committed to new domestic 300mm capacity since 2022, but both have scouted Gyeongsang sites. Second, whether secondary chip equipment suppliers — Tokyo Electron Korea, Applied Materials Korea — announce co-location or service hubs in Gumi, which would indicate serious OEM interest. Third, Gyeonggi Province's response: if they match Gumi's rate, the incentive floor drops nationwide and reshapes Korean fab economics for the next cycle.

The provincial land auction for the first Gumi semiconductor zone closes in Q3 2025, with groundbreaking eligibility starting January 2026. No bidders named yet, but the price is now public.
