For Korean exporters, the U.S. Supreme Court docket’s ruling in opposition to IEEPA-based reciprocal tariffs didn’t carry readability. It changed one authorized construction with one other. Inside days, President Donald Trump invoked Part 122 of the Commerce Act to impose a worldwide tariff, later elevating it to fifteen %. For Korean SMEs and export-based startups, the shift introduces a 150-day planning window stuffed with strategic uncertainty.
Korea Convenes Public–Personal Assembly After Part 122 Tariff Transfer
On February 23, the Ministry of Commerce, Business and Power (MOTIE) convened a joint public–personal response assembly on the Korea Chamber of Commerce and Business in Seoul. Financial organizations, main business associations, related ministries, and export assist establishments attended.
The assembly adopted the U.S. Supreme Court docket’s choice declaring reciprocal tariffs imposed underneath the Worldwide Emergency Financial Powers Act (IEEPA) illegal. Instantly afterward, President Trump introduced a 10 % world tariff underneath Part 122 of the Commerce Act and subsequently raised it to fifteen %.
In response to the ministry, Part 232 product-specific tariffs stay in impact. The federal government additionally anticipates potential investigations underneath Part 301 and different various authorized mechanisms. Officers said that these overlapping instruments might generate “advanced impacts” on Korean business and exports.
The federal government stated it can carefully monitor U.S. follow-up measures and actions by different international locations, aiming to reduce uncertainty for Korean corporations.
Why the 150-Day Part 122 Interval Issues Now
Part 122 authorizes the U.S. president to impose tariffs of as much as 15 % for a most of 150 days in response to balance-of-payments issues. That point restrict is now central.
Authorized consultants emphasised that the 150-day window might turn out to be a turning level. If no substitute authorized framework emerges after the interval expires, a tariff hole might happen. On the identical time, various mechanisms reminiscent of Part 301 investigations or expanded product tariffs underneath Part 232 stay accessible to the U.S. administration.
In sensible phrases, Korean exporters face at least 5 months of constrained visibility in U.S. pricing situations. The uncertainty extends past headline tariff charges. It consists of refund procedures, investigation threat, and potential sector-specific changes.
The Korea Worldwide Commerce Affiliation famous that if the U.S. tariff construction transitions to a “Most-Favored-Nation tariff plus 15 % underneath Part 122” mannequin, Korea’s competitiveness as an FTA accomplice might enhance relative to non-FTA international locations. That evaluation, nevertheless, is determined by how the framework evolves after the 150-day interval.
Minister Kim Jung-kwan: “Pleasant Consultations” and Aggressive Adjustment
On the February 23 assembly, Minister Kim Jung-kwan said that the federal government will proceed “pleasant consultations” with the US to make sure that the stability of advantages secured by prior Korea–U.S. tariff agreements isn’t undermined.
He warned that if a uniform 15 % world tariff is utilized, modifications in relative aggressive situations for Korean corporations ought to be anticipated.
Kim additionally stated the federal government will pursue export diversification and competitiveness insurance policies “persistently” and be certain that corporations obtain well timed info relating to uncertainties surrounding tariff refunds.
He famous that extra U.S. measures and developments in different main economies will likely be carefully monitored, and that mid- to long-term response methods will likely be explored calmly.
Individually, authorized analysts cautioned that tariff refunds following the IEEPA ruling are usually not automated. Eligibility could depend upon litigation participation and the finalization standing of particular person import entries.
Authorized Authority Shift With out Threat Discount
The core pressure isn’t about one tariff price changing one other. It’s in regards to the authorized structure.
The Supreme Court docket invalidated tariffs underneath IEEPA as a result of the statute doesn’t explicitly authorize tariff imposition. The Trump administration responded by invoking authorities that had been explicitly delegated by Congress a long time in the past, together with Sections 122, 301, and 232.
From a Korean SME perspective, the danger didn’t disappear. It modified channels.
Part 122 creates a brief tariff construction with an outlined period. Part 301 opens the opportunity of focused investigations into alleged unfair commerce practices. Part 232 permits product-specific tariffs tied to nationwide safety assessments. Every mechanism carries completely different procedural and sectoral implications.
For export-dependent SMEs with out in-house commerce regulation capability, the multiplicity of authorized tracks complicates planning. The problem is much less a couple of single 15 % quantity and extra about layered regulatory publicity.
How Part 122 Reshapes U.S. Market Technique for Korean SMEs
Korean startups and SMEs have more and more embedded U.S. market entry into development projections. In 2024 and 2025, commerce volatility already pressured pricing revisions throughout manufacturing-linked SMEs, particularly these tied to metal, automotive elements, and industrial inputs.
Beneath the Part 122 framework, short-term predictability improves solely marginally. A 150-day window is barely adequate for customs implementation. However it’s nonetheless inadequate for capital allocation or long-term provide chain restructuring.
For know-how startups exporting {hardware} elements or superior supplies, tariff publicity intersects with cross-border enterprise capital choices. Traders assessing U.S. income dependency should now think about momentary tariff authorities that may be changed by various authorized instruments at quick discover.
The structural query turns into one in all threat distribution. Massive conglomerates can soak up authorized volatility by world manufacturing networks. However not all export-based startups and SMEs can do the identical. That asymmetry deepens the policy-execution hole between nationwide commerce diplomacy and firm-level resilience.
The ministry’s public–personal coordination alerts consciousness of that imbalance. But coordination doesn’t eradicate structural publicity.
Planning Inside a Transferring Authorized Framework
The subsequent 5 months are usually not a pause. They’re a compressed negotiation part.
If Part 122 expires with out substitute, sure items might quickly revert to decrease tariff situations. If changed by Part 301 findings or expanded Part 232 measures, sector-specific stress might intensify as a substitute of ease.
Korean SMEs and startups exporting to the US are subsequently working inside a conditional surroundings. Pricing fashions, contract clauses, and refund methods should now incorporate authorized volatility as a baseline assumption.
For world stakeholders, the episode highlights how commerce governance is more and more intertwined with startup threat administration. Market entry is now not solely about demand. It is usually about statutory interpretation and government authority.
The 150-day window isn’t merely a countdown. It’s a strategic take a look at of how shortly governments and corporations can recalibrate inside shifting authorized boundaries.
