South Korea Finalizes Five-Year Anti-Dumping Duties on Hot-Rolled Steel from China and Japan: Full Rate Schedule, HS Codes, and Procurement Impact
South Korea's Korea Trade Commission (KTC) issued a final affirmative determination on 23 February 2026, imposing five-year anti-dumping duties on hot-rolled carbon and alloy steel imports from China — at rates of 28.16% to 33.10% — and from Japan — at rates of 31.58% to 33.43% — with price undertaking exemptions available for participating companies.
Effective date and legal basis
Timeline and authority
The Korea Trade Commission issued the final notice on 23 February 2026. Following the affirmative determination, the KTC formally requested the Ministry of Economy and Finance to impose the duties. The measures carry a five-year duration. This is consistent with standard anti-dumping practice under Korea's Trade Remedy Act and WTO Anti-Dumping Agreement Article 11.3.
The five-year term distinguishes this from provisional measures. It represents a definitive trade remedy. Importers and procurement teams should treat it as a fixed feature of the Korean import cost structure for the duration, not a temporary adjustment pending further review.

Products covered and HS code classification
Scope of the measures
The measures cover carbon steel and alloy steel hot-rolled flat products. Both coil and non-coil form are included. The product scope spans standard hot-rolled strip and plate, wide flat products, and alloy steel flat-rolled categories. In total, 38 HS sub-headings under Chapters 72 and 72 are subject to the final determination.
Importers must verify the exact HS classification of each product line at the Korean customs border. Sub-heading classification errors can result in incorrect duty assessment or retroactive adjustment. Confirm the applicable sub-heading with a licensed Korean customs agent before shipment.
All 38 sub-headings reference Korea's customs tariff schedule (HSK). HS 7208.xx — hot-rolled flat products in coil and non-coil form. HS 7211.xx — hot-rolled strip of width less than 600 mm. HS 7225.xx and 7226.xx — flat-rolled products of other alloy steel. Importers should confirm classification with a licensed Korean customs broker before shipment.
Duty rates and price undertaking arrangements
China — definitive AD duty rates
The KTC has applied a duty range rather than a single uniform rate for Chinese producers. This reflects individual dumping margin calculations for cooperating exporters. The range is 28.16% to 33.10%. Non-cooperating or unreviewed exporters typically receive the higher end of the range as the residual rate.
| Origin | Duty rate range | Duration |
|---|---|---|
| China | 28.16% – 33.10% | Five years (definitive) |
| Japan | 31.58% – 33.43% | Five years (definitive) |
Price undertaking exemptions
The KTC approved price undertakings from a number of firms. Companies that enter into and comply with these price agreements are exempt from the AD duty. This is a significant commercial provision. It means that some Chinese and Japanese mills may continue to supply the Korean market without paying the headline duty rate — provided they honour the agreed minimum price floor.
Buyers sourcing from a specific Chinese or Japanese producer should confirm whether that producer has an approved price undertaking in place. If it does, the landed cost impact is different from that facing producers subject to the full duty rate. This distinction is material for cost modelling and supplier selection decisions.
Impact on Chinese exporters and overseas buyers
Commercial consequences for Chinese and Japanese exporters
Duties in the 28%–33% range are commercially prohibitive for most standard hot-rolled flat steel trade. At current market prices, a 33% ad valorem tariff adds a cost layer that eliminates the landed price advantage that Chinese and Japanese material held over Korean domestically produced flat steel.
For exporters without an approved price undertaking, the Korean market is effectively closed for competitively priced material. This is not a marginal increase in cost — it is a structural exclusion that forces a fundamental reassessment of routing and destination strategy for affected product volumes.
Immediate priorities for importers and buyers
- Verify price undertaking status for each named supplier. If your current Chinese or Japanese source has an approved undertaking, the duty impact may not apply. Confirm this directly with the supplier and obtain written documentation before relying on it.
- Reassess landed cost models for Korean-destined shipments. All cost projections built on pre-determination pricing are now outdated. Recalculate landed cost using the applicable duty rate for each supplier.
- Check shipment timing against the effective date. Goods that cleared Korean customs before the duty took effect are not subject to the new rate. Confirm entry dates with your licensed Korean customs broker.
- Open purchase orders need immediate review. Any order confirmed for future delivery into Korea now carries a different landed cost. Determine whether contracted prices remain commercially viable after the duty is applied.
Broader market context
South Korea joins a growing list of jurisdictions with active trade remedy regimes for flat hot-rolled steel. The US, EU, UK, Mexico, India, and Brazil all operate comparable AD frameworks for this product category. The convergence of measures across major consuming economies narrows the number of destinations where Chinese and Japanese hot-rolled material can be sold without a duty surcharge.
For procurement teams with multi-market sourcing programmes, this pattern is strategically significant. It compresses available trade routes. It also increases the value of suppliers from non-subject origins that can serve multiple markets without AD exposure.
Alternative sourcing considerations
Origin and supply alternatives for the Korean market
- Non-subject origins. Hot-rolled flat steel from origins not named in the KTC determination — including India, Taiwan, Southeast Asian producers, and certain EU mills — is not subject to these duties. Evaluate whether specifications, lead times, and delivery requirements can be met from these origins.
- Domestic Korean producers. POSCO and Hyundai Steel are the principal domestic hot-rolled flat steel producers in Korea. Sourcing domestically eliminates import duty exposure entirely. Domestic availability and pricing should be benchmarked against the duty-inclusive landed cost of imported material.
- Price undertaking participants. If a specific Chinese or Japanese producer has an approved price undertaking, it may still be a cost-competitive source for the Korean market. The undertaking price floor and compliance requirements should be fully understood before relying on this route.
Specification review for corrosion-critical applications
In applications where hot-rolled carbon steel has been selected on cost grounds, and where the service environment involves corrosion, hygiene, or elevated temperature requirements, the landed cost impact of these duties narrows the price gap with stainless alternatives. A specification review may be warranted.
TISCO's 304 stainless steel coil and 316L stainless steel coil serve food processing, chemical handling, architectural, and marine applications. These grades are not subject to the KTC hot-rolled carbon steel AD determination. They offer a structurally different cost trajectory — one not exposed to the same trade remedy risk that now affects flat carbon steel imports.
| Response option | Best suited for | Key consideration |
|---|---|---|
| Verify price undertaking status | Buyers with existing China / Japan supplier relationships | Get written confirmation; undertaking must remain active |
| Switch to non-subject origin (India, Taiwan, EU) | Large-volume, standard spec requirements | Verify MTC compliance and lead time compatibility |
| Source from domestic Korean producers | Projects requiring domestic content or short lead times | Benchmark POSCO / Hyundai against duty-inclusive import cost |
| Evaluate stainless for corrosion-critical uses | Food, chemical, marine, architectural applications | 304 or 316L — not subject to this AD determination |
