Korea KTC provisional anti-dumping duties (22.34–33.67%) on Chinese zinc-coated cold-rolled steel

Mechanism

Korea's anti-dumping framework is bifurcated: the KTC (Korea Trade Commission, under MOTIE) conducts the dumping-margin and injury investigation and issues determinations; the Ministry of Economy and Finance (MOEF) then issues a public notice imposing the provisional or definitive duties. The 16 April 2026 action is the KTC preliminary affirmative determination — the agency formally recommends MOEF operationalise the duties.

The duties are differentiated by Chinese producer based on the preliminary individual dumping margins:

The "all-others" rate of 25.75% is used as the representative tariff_rate_pct in this action's frontmatter for downstream consumers; the producer-specific range (22.34–33.67%) is documented above.

Product coverage — zinc and zinc-alloy coated cold-rolled steel products with thickness <4.75mm. SteelOrbis reports the covered HS codes as 7210.41.0000, 7210.49.9010, 7210.49.9090, 7210.61.0000, 7210.70.2000, 7212.30.9010, 7212.30.9090, 7212.40.2000, 7225.92.9091, 7225.92.9099, 7226.99.3000.

Petitioners — Dongkuk CM, KG Steel, SeAH CM (filed November 2025). The two integrated majors (POSCO, Hyundai Steel) are not formal co-petitioners but are the principal beneficiaries of the perimeter.

Provisional duration — typically up to 4 months under Korean trade-remedy law while the KTC completes the final injury and dumping-margin determination, after which MOEF may impose definitive duties for an initial 5-year term renewable on review. KTC public statement: a final determination is expected around September 2026 following on-site verifications, public hearings and additional data collection.

Why now — the Section 232 spillover

The KTC investigation was initiated in November 2025, five months after the US Section 232 50% steel-tariff escalation took effect (2025-06-04, see 2025-02-11-us-section-232-steel-aluminum-global-tariff-reinstatement amendment). The 25% → 50% tariff hike priced Chinese steel out of the US market and redirected Chinese supply into open Asia-Pacific markets, with Korea (the world's 6th largest steel producer and a major net-import gateway for Chinese galvanized CRC) absorbing a disproportionate share. The Korean galvanized CRC market is particularly exposed because:

• Domestic Korean producers (POSCO, Hyundai Steel, KG Steel, Dongkuk)

serve large captive demand from Korean automakers (Hyundai, Kia) and shipbuilders, and the surge in low-priced Chinese imports threatened Korean producer margins.

• Chinese coated-CRC capacity is structurally oversupplied

(post-property-bust domestic-demand collapse) and will continue seeking export outlets while Section 232 remains at 50%.

This places the Korean action in the same arc as the EU's parallel escalation (2025-03-24 EU Steel Safeguard tightening + 2026-04-13 EU Steel Safeguard Successor) and the December 2025 India steel flat products safeguard duty: a coordinated G20-importer trade-defence response to Chinese steel diversion, even though Korea's instrument is a country-specific anti-dumping order rather than an erga omnes safeguard.

Downstream implications

• Korean steelmaker margins — POSCO, Hyundai Steel, KG Steel and

Dongkuk benefit from price-floor relief on coated-CRC for the duration of the provisional duties; expect Q2-Q3 2026 ASP recovery in galvanized product lines.

• Korean downstream consumers — Hyundai/Kia, LG/Samsung white

goods, and Korean construction will see input-cost normalisation as Chinese imports retreat. Some risk of margin squeeze if domestic producers raise prices toward the new effective import ceiling.

• Chinese producers — Inner Mongolia Baotou, Shougang Jingtang

and Winstone face material loss of Korean market access at preliminary rates that exceed their dumping margins by design. Likely diversion to ASEAN (Thailand, Vietnam, Indonesia) and Middle East — watch for parallel petitions in those markets.

• Bilateral KR-CN trade — KTC trade-remedy actions against China

are escalating: Feb 2025 hot-rolled coil AD (38% definitive), Apr 2026 coated-CRC AD provisional. This is a structural pivot in Korean trade-defence posture toward China, in parallel with the Dec 2025 US-Korea Strategic Trade & Investment Deal (2025-12-04) which aligns Seoul more closely with Washington's China-policy frame.

• WTO Anti-Dumping Committee — Korea will notify the AD case in

the next G/ADP/N/ semi-annual report; this is the canonical international record of dumping-margin and injury findings once available.

Open questions

• ~~Exact MOEF public notice date~~ — resolved (see amendments):

MOEF Notice 2026-80, effective 12 June 2026 through 12 October 2026.

• Whether the KTC final determination in September 2026 will narrow

or expand the producer list (Korean AD reviews can add newly-shipping respondents in the final phase).

• Treatment of Chinese-origin coated-CRC trans-shipped through third

countries (a circumvention angle that mirrors the US ITC's parallel circumvention inquiries on Korean CORE — see Federal Register 2026-06449 of 2 Apr 2026, the inverse-direction circumvention pattern).

• Whether Korean steelmakers will follow with petitions covering

remaining product gaps (electro-galvanized, tinplate, colour-coated steel from China).
