Is the wall leaking? Titanium dioxide after the 2025 anti-dumping wave

Circumvention-track case (R72), companion to the price wedge. The wedge measures scarcity; this track measures the other half — is a trade control actually holding, or is the controlled supply re-entering the buyer under a laundered or relocated origin? This is a DUAL-SCORE / alternative-track signal, never folded into any Tier-1 exposure score. Research, not investment advice; relocation and ownership links are traced to named public filings, never asserted as illegal on any single shipment.

Unlike the antimony/gallium China-export-ban cases, the control here is import- side — a wave of national anti-dumping (AD) duties on Chinese titanium dioxide, the same regulatory family as the solar-modules case. And unlike solar, the fingerprint traced so far is not trans-shipment relabelling (mode A) but capacity relocation with a common-ownership tell (mode B) — with a fresh twist worth naming: the dominant Chinese producer is buying the very Western "alternative" supply base that AD-hit buyers would switch to.

Verdict

Across 13 months (Jan-2025 → Oct-2025) five jurisdictions closed anti-dumping finals against Chinese TiO₂, four of them still in force. China supplies the majority of the material they are walling out: ~55%+ of world capacity (6.05 Mt end-2024, heading to ~7 Mt in 2025), a record 4.766 Mt output and a record 1.90 Mt of exports in 2024 (+15.8% YoY). The single largest producer on earth, LB Group (Lomon Billions, SZ:002601, ~1.51 Mt capacity), carries the top duty in most of these orders — and, in the same weeks the orders landed, moved to acquire a 150 kt/yr chloride-process plant inside the walled market.

The AD wall (import-side control)

Sources: ETIO2 / Titanos consolidated ruling summaries; Brazil GECEX Resolução 802 (23 Oct 2025); EAEU EEC definitive (13 Feb 2025, implemented 17 Oct 2025); EU Commission Implementing Regulation (final 9 Jan 2025); India DGTR final (12 Feb 2025) subsequently quashed/remanded by the Calcutta High Court. Capacity/output/ export figures: ECHEMI, Blooming, Shanghai Metals Market, Titanos market reviews.

China's exports were already registering the squeeze before the finals fully implemented: rutile-grade TiO₂ exports fell −22.2% MoM / −13.7% YoY in April 2025 as barriers thickened. India — China's #1 destination at ~15–16% of 2024 exports (307.5 kt) — is the pressure valve: its duty was quashed in September 2025, so that channel reopens rather than needing to be laundered. The other 2024 destinations (Brazil 7%, Turkey 6%, Korea 5%, Russia 4%, Indonesia/Vietnam/ UAE 4% each, Egypt/Malaysia 3%) are where re-routing incentive concentrates.

The escape-hatch acquisition (the common-ownership tell)

The traceable fingerprint is not an implausible-origin volume surge — it is a disclosed corporate move that changes the flag on real capacity:

> LB Group (China; carries the EU's top 32.3% duty) → Asset Purchase > Agreement, Oct 2025, to buy Venator Materials UK Ltd's Greatham (Teesside) > plant — 150 kt/yr, chloride-process (Venator's only chloride facility) — > for US$69.9 m + US$14.2 m taxes/fees; acquisition completed. LB also > committed US$50 m to a UK subsidiary and US$5 m to a Malaysia subsidiary > "to develop its overseas business."

The timing is the tell: LB signed for a UK/EU-origin chloride plant in the same weeks the EU imposed 32.3% on LB's China-origin tonnes and Brazil/Saudi finals landed. TiO₂ produced at Greatham legitimately carries UK origin under substantial-transformation rules — so this is not a phantom flag or smuggling; it is real manufacture. But the economic origin — ownership, pricing, group strategy — stays with the producer the duties targeted.

The twist that generalises: Greatham is exactly the kind of Western supply an AD-hit buyer would diversify *toward*. Venator's estate is being carved up to non-Venator owners (Indorama took Venator's Spanish TiO₂ business); LB taking its UK chloride jewel means a buyer "moving away from China" to a UK/Venator source may be circling back to the same corporate owner. The escape hatch is being bought by the party you are escaping.

Modes present

• (B) capacity relocation / common-ownership — the confirmed leg: LB Group

builds/acquires real capacity abroad (UK Greatham, Malaysia subsidiary) and can ship under the new flag, Chinese-owned. Distinct from mode A (no relabelling of molecules) and from mode C (no substantial-transformation of a controlled feedstock — Greatham makes finished pigment).

• Escape-hatch capture — a mode-B sub-variant this case names: the controlled

producer acquires the alternative supplier that AD-hit buyers switch to, so diversification converges back on the controlled owner and the country-of-origin line stops tracking economic exposure.

• (A) trans-shipment relabelling — not evidenced yet. A confirming mode-A

fingerprint would be a ~0-capacity third country surging TiO₂ into Brazil/EAEU/ EU/Saudi post-final. That customs surge is prospective (finals mostly Oct 2025, Greatham only just completed) — see the gate note.

Why it matters for the buyer

1. Country-of-origin will read "UK" / "Malaysia" — economically still LB Group. Any exposure model keyed on stated origin will book a Greatham tonne as Western supply and understate China-corporate concentration. The ownership cross-check is the correction. 2. Diversification can be illusory. A risk team switching "off China" toward Venator/Western pigment should verify the plant's owner, not just its flag. 3. Leading indicator to watch. If UK (Greatham) and Malaysia TiO₂ export lines into the AD-walled markets surge through 2026, that is mode B becoming visible in customs — the confirming fingerprint this case flags in advance.

Method, honesty rails & gate

• Control type: import-side anti-dumping duties (buyer jurisdictions), not a

Chinese export ban. Producer = China. Same regulatory family as the solar case.

• UK is a genuine producer (Greatham legacy) → the volume-implausibility (mode

A) test does not apply to the UK leg; the tell is ownership, sourced to LB Group's own press releases and Yicai/ECHEMI coverage.

• Partly detector-negative on switching: TiO₂ has real non-Chinese producers

(Chemours, Tronox, Kronos, INEOS, Indorama), so the AD walls can bite via price and genuine supplier-switching — but the LB–Venator move shows that "alternative" base being consolidated under Chinese ownership, which is the signal.

• India valve: the quashed Indian duty reopens China's largest market and

lowers laundering incentive there — a reason not to over-read a single-market origin table.

• GATE 0. The control (five AD finals, dates/rates) and the mode-B/common-

ownership tell (LB → Greatham 150 kt chloride, US$69.9 m; UK + Malaysia subsidiaries) are fully traced to named public sources. What is not yet verifiable is the confirming customs fingerprint — UK/Malaysia-origin TiO₂ surging into the AD-hit markets after the acquisition — because the orders and the deal are only months old. Upgrade to GATE 1 when 2026 import-by-origin data for Brazil (Comex Stat), the EAEU, and the EU shows a Greatham/Malaysia-origin step-up. Alternative-track only; never folded into any Tier-1 score.
