Is the ban leaking? Steel — the whack-a-mole cascade, the width trick, and why melt-and-pour will not close it

Trade-flow companion to the price wedge (R72). DUAL-SCORE / alternative-track signal — never folded into any Tier-1 exposure score. Research, not investment advice; origin-relabelling is INFERRED from statistical implausibility plus public ownership records, never asserted as smuggling on any single shipment.

Steel is the corpus's first bulk industrial entry, and it breaks the house detector. Every prior case leaned on volume-implausibility: a country with ≈0% of world capacity cannot export what it does not make. That test is useless here — Viet Nam, Indonesia, Türkiye and Thailand all genuinely make steel. What steel offers instead is something no other material in the corpus has: three successive transit hops, each one closed by an adjudicating authority, each closure followed within months by the next hop — plus a sixth circumvention mode that no origin-based detector can see at all.

Verdict

Between 2022 and 2025 the US corrosion-resistant-steel (CORE) import line re-routed twice and the EU hot-rolled-coil (HRC) line once, in each case within one to two years of the prior route being shut. The moves are large, abrupt, and line up with the dates of specific trade-defence instruments rather than with any change in underlying demand.

Hop 1 → Hop 2 → Hop 3, on the US CORE line. UN Comtrade, reporter USA (842), imports, annual, HS 7210 (flat-rolled iron/steel ≥600 mm, clad/plated/coated — the CORE line), net weight, thousand tonnes (kt):

Read the shares, not the levels — the 2025 world total falls 28% because the US reinstated universal 25% Section 232 steel tariffs on 12 March 2025. Against that falling tide, Indonesia and Thailand rise in both absolute volume and share.

Viet Nam's near-total disappearance is not a market event. Commerce issued final affirmative AD and CVD determinations on CORE from ten trading partners — including Viet Nam — on 26 August 2025, with provisional measures running from the February and April 2025 preliminary determinations. The line went to ~zero in the same window.

Then, in the following quarter, Commerce opened inquiries into where it went:

• 25 March 2026 — country-wide circumvention inquiry into CORE **completed in

Indonesia using hot-rolled and cold-rolled steel manufactured in China**, against the AD/CVD orders on CORE from China (FR 2026-05807; requested by Nucor and Steel Dynamics; preliminary determinations intended by 24 August 2026).

• 2 April 2026 — country-wide circumvention inquiry into CORE **completed in

Thailand using components produced in Korea**, against the AD/CVD orders on CORE from Korea (FR 2026-06449).

The two surgers in the table are the two subjects of the two inquiries. That is as close to independent confirmation of a trans-shipment read as this corpus gets: the US authority itself alleges the mechanism, naming the input origin.

The EU line: one hop, and it is enormous

UN Comtrade, reporter EU-27 (97), imports, annual, HS 7208 (hot-rolled flat, ≥600 mm, not clad), net weight, kt. No EU member state appears anywhere in the partner list, so this is the extra-EU basis:

On 25 September 2025 the Commission imposed definitive anti-dumping duties on HRC from Egypt (11.7%), Japan (6.9–30%) and Viet Nam (12.1%) by Implementing Regulation (EU) 2025/1919, and terminated the parallel India investigation. In the same calendar year all three duty-hit origins fall 44–76% — and Indonesia more than triples, going from the EU's #8 HRC supplier to its #2, adding 1.4 Mt in twelve months. China's own direct line has been ~0.1–0.9% since the 2017 EU duties: the direct route has been shut for years. Something else is carrying the volume.

The input-line test — and where it stops working

For bulk materials the ≈0%-capacity test fails, so the corpus falls back to the diagnostic established on Russian crude and Xinjiang cotton: read the INPUT line into the surger, not the finished-good origin line. Indonesia's own reported imports of Chinese HRC (UN Comtrade, reporter Indonesia 360, imports, HS 7208):

The two reporters agree to within ~2% in 2024 — a clean second-source validation. And here the honest reading turns against the simple relabelling story: Indonesia shipped 2,057 kt of HRC to the EU in 2025 while importing only 716 kt of Chinese HRC. It cannot be re-flagging Chinese coil; it is making coil. The Chinese input line actually fell 17% in 2025, in the same year Indonesia imposed its own provisional anti-dumping duty on Chinese HRC.

That is the finding. Indonesia's surge is not mode A or mode C — it is mode B, capacity relocation: real furnaces, real melt, genuinely Indonesian origin, Chinese-owned.

The corporate pipe (the common-ownership tell)

Two ownership chains are documented in public instruments, not inferred:

1. Chinese ownership of the Indonesian capacity — named by the EU itself. Commission Implementing Regulation (EU) 2020/1408, imposing the anti-dumping duty on hot-rolled stainless from Indonesia, names the exporting producers as PT Indonesia Tsingshan Stainless Steel (ITSS) and PT Indonesia Guang Ching Nickel and Stainless Steel Industry (GCNS), together with "their related suppliers established in the Indonesia Morowali Industrial Park ('IMIP')" and PT Tsingshan Steel Indonesia (TSI). The controlling group's name is literally carried in the Indonesian subsidiary's name — the same tell as Guangxi Youngsun → Thai Unipet in the antimony case. On the carbon-steel side, PT Dexin Steel Indonesia, the Morowali integrated mill, is a joint venture of Delong Holdings, IMIP and Shanghai Decent Investment, described by Mysteel on completion of its first expansion phase (steelmaking capacity 4→7 Mt/yr, September 2023) as the largest Chinese-invested integrated steel mill outside China; its 1,780 mm hot-strip mill started up mid-2024 — one year before the EU HRC surge.

2. A two-hop chain the EU adjudicated in full. Commission Implementing Regulation (EU) 2023/825 (17 April 2023) extended the Indonesian hot-rolled stainless duty to product consigned from Türkiye, on findings that are the cleanest mode-C arithmetic in the corpus:

The Commission found the Indonesian slabs constituted "almost 100% of the total value of the parts" processed by the Turkish producer Çolakoğlu, with value added by the Turkish completion operation far below the 25% statutory threshold. Net chain: Tsingshan (China) → PT ITSS / GCNS at IMIP (Indonesia) → Çolakoğlu (Türkiye) → EU. Three flags, one owner at the head of it.

Mode F — the width trick, and why no trade dataset can see it

Steel introduces a circumvention mode the corpus has not carried. On 4 July 2025 Viet Nam's MOIT (Decision 1959/QĐ-BCT) imposed definitive anti-dumping duties of 23.10–27.83% on Chinese HRC, effective 6 July 2025 for five years. The scope was written physically: thickness 1.2–25.4 mm, carbon ≤0.3%, width not exceeding 1,880 mm.

Chinese mills shipped wider coil. On 17 April 2026 MOIT imposed a provisional anti-circumvention duty of 27.83% on Chinese HRC of width over 1,880 mm up to 2,300 mm, on preliminary findings that the wide product was a minor modification of the same good made to escape the July-2025 scope.

Call this mode F — specification / scope shifting. Its properties are unlike every other mode in the register:

• Origin never changes. The goods are declared Chinese, correctly, at every

hop. There is no phantom flag, no transit country, no shell.

• It is invisible in trade data. Coil width is not an HS distinction. Both the

≤1,880 mm and the >1,880 mm product sit inside the same HS 7208 subheadings, so a Comtrade or Comext series shows nothing at all. Neither the volume-implausibility test nor the input-line test can fire.

• Only the measure's own scope language catches it — which means detection

requires reading national trade-remedy decisions, not customs statistics.

Mode F is not new behaviour, only newly registered. Its ancestor is China's boron-doped steel: adding trace boron (finished steel above ~0.0008% boron) let exporters declare product as alloy steel and claim a 5–13% export tax rebate. Beijing removed the boron-added rebate effective 1 January 2015; trade press reported the practice migrating to chromium, where ~0.3% Cr reportedly preserved the same rebate treatment. A compositional or dimensional tweak worth under a percent of cost, made purely to move a tariff line, is the cheapest circumvention there is.

Three regulators converged on melt-and-pour in 12 months

The clearest external confirmation that origin-washing is the dominant steel leak is that three jurisdictions independently moved to melt-and-pour origin — attributing origin to where the steel was first produced in liquid form, not where it was last rolled — inside a single year:

The EU has run the test before: in the stainless cold-rolled anti-circumvention extension it imposed monitoring specifically to determine whether product was made from steel melted and poured in Indonesia.

But melt-and-pour closes mode C and is blind to mode B. Dexin's coil is melted and poured in Indonesia. Under a melt-and-pour rule its origin is Indonesian — correctly, unambiguously, permanently. The rule reclassifies nothing about the largest single line in the 2025 EU table. Origin-based instruments cannot reach ownership-based relocation; only an ownership test could, and no importing jurisdiction has proposed one.

What this implies for the Tier-1 blind spot

• Bilateral China-share is meaningless for steel. China's direct share of EU

HRC imports is 0.9% and of US CORE imports 4.2%. Any Tier-1 exposure score reading those numbers concludes European and American steel buyers are essentially un-exposed to Chinese supply policy. The 2025 Indonesian lines — 2,057 kt into the EU, 88 kt of CORE into the US, out of Chinese-owned Morowali capacity — say otherwise.

• The relevant control is now upstream and in force. MOFCOM/GACC Announcement

No. 79 (9 December 2025) reinstated export licensing across ~300 HS steel lines from 1 January 2026 — the first Chinese steel export licensing since 2009, and the first application of the licensing instrument to a bulk commodity. Chinese exports hit a record 119.02 Mt in 2025 (+7.5%) with a record 11.3 Mt in December alone, reported as front-loading ahead of the licence requirement. A licensing regime over a supplier that owns the transit country's mills is a different exposure from a tariff on a flag.

• Route half-life is roughly two years. Viet Nam ran as the US CORE hop from

the 2016 China orders until the August-2025 orders; Indonesia and Thailand picked it up within two quarters and were under inquiry within three. Any exposure model that treats a supplier-origin mix as stable over a five-year horizon is mis-specified for this material.

Caveats

• Inference, not proof. Nothing here asserts that any individual shipment was

smuggled or falsely declared. The US circumvention inquiries are initiations — allegations under investigation, with preliminary determinations not due before 24 August 2026. The Vietnamese anti-circumvention duty is provisional, in force 120 days from 17 April 2026, on preliminary findings.

• A mill in a transit country is not evidence of laundering. Dexin and IMIP are

real industrial assets serving real regional demand. Mode B is lawful. The signal is that origin data stops describing control, not that anyone broke a law.

• Reporter divergence is large on this material. For HS 7208 into Viet Nam in

2023, China reports 6,441 kt of exports against Viet Nam's 4,749 kt of imports — a 36% gap. Some of that is CIF/FOB and coverage convention; the corpus does not read a gap of that shape as a finding. Where both reporters were available (Indonesia 2024) they agree to ~2%, which is why that pair is used above.

• 2025 Chinese-reported annual data was not yet in the Comtrade preview tier

when this was compiled (queries returned empty), so 2025 mirror checks are unavailable and the 2025 column rests on importer reporting only.

• HS 7210 is broader than the CORE AD/CVD scope and HS 7208 broader than the

EU HRC AD scope; the tables therefore track the product family, not the measure's legal scope. Directionally this understates nothing, but exact attribution of a tonne to a measure is not available at HS-6.

• Levels versus shares. Both the US 2025 total (−28%) and the EU 2025 total

(+6%) move for reasons unrelated to circumvention — Section 232 at 25% from March 2025 on one side, safeguard quota mechanics on the other. Shares are the load-bearing column.

• The Korean MOTIE molten-steel proposal rests on a single secondary outlet and is

reported here as proposed, carrying no figure in any table. It is the weakest link in this case and should be re-verified against the MOTIE notice before being cited downstream.
