Is the order leaking? Aluminium foil after the US AD/CVD orders on China

Alternative-track / dual-score signal — never folded into any Tier-1 exposure score. Research, not investment advice. Origin-relabelling is INFERRED from the trade pattern plus public filings; no single shipment is asserted to be evasive. Aluminium foil (HS 7607.11/7607.19) is the battery-current-collector and flexible-packaging input; China is the dominant exporter.

Register note. The US orders themselves (A-570-053 / C-570-054, April 2018) are not tracked in our IPTM register — register-state, not world-state. The case is anchored to the filed Türkiye sunset extension (Tebliğ 2026/16) on the same Chinese foil, and the Türkiye read-across is below.

Verdict

• China's direct line collapsed; a Thai line appeared from nothing. US imports

of HS 7607.11+7607.19 from China fell $439.7m (2017) → $79.0m (2025), −82 % (share 50.6 % → 6.4 %). Thailand went $1.8m → $247.5m (share 0.2 % → 20.0 %) and is now the #1 origin.

• The pipe has a name, and Commerce already adjudicated it. The US Department

of Commerce found foil completed in Thailand and Korea from Chinese foil/sheet is circumventing the China orders (88 FR 82824, 27-Nov-2023; deposits back to 18-Jul-2022). The first Thai company on its list, Dingheng New Materials Co., Ltd., is the Thai subsidiary of SSE-listed 江苏鼎胜新能源材料股份有限公司 (Jiangsu Dingsheng New Energy Materials), incorporated 12-Sep-2018 — five months after the orders.

• Mode B / C⁻: real capacity relocated by the controlled producer (B), whose

Thai "completion" of Chinese inputs Commerce ruled minor or insignificant (C⁻, adjudicated-failed transformation wash). The CIT sustained the Korea leg in full (Hanon Systems Alabama Corp. v. United States, Slip Op. 25-94, 21-Jul-2025).

• The line did not go away after the ruling. Thailand dipped to $62.5m in 2023

and rebounded to $247.5m in 2025 under the certification regime. Whether that is genuine non-Chinese input or continued leakage is not decidable from public data — the open question this case leaves.

The implausible-origin table — US imports, HS 7607.11 + 7607.19 (US$ m, annual)

Shares of world: China 50.6 % (2017) → 17.0 % (2018) → 10.0 % (2022) → 6.4 % (2025); Thailand 0.2 % → 16.2 % (2022) → 5.4 % (2023) → 12.9 % (2024) → 20.0 % (2025).

Values only — Comtrade net-weight for this series is unreliable in 2020 and the 2025 World total (partner kg exceed the World kg), so no unit-value or tonnage claims are made. Commerce's own record measure agrees in direction: Korea +973.7 % and China −66.2 %, Jul-2012–Mar-2017 vs Apr-2017–Dec-2021 (quoted in Slip Op. 25-94, p. 32–33).

The corporate pipe (the common-ownership tell)

Match basis: "Dingheng" is the exact pinyin of 鼎亨, the business line is foil, and the Rayong subdistrict matches. Commerce's notice gives no address, so the name↔filing link is by romanisation plus location, not a registry number.

Open question — Ding Li New Materials Co., Ltd. A secondary trade-data aggregator describes it as a second Dingsheng-group Thai base (est. 2017); not traced to a Dingsheng filing or Thai DBD registry record in this wake. Left unlinked.

Türkiye read-across (the anchor action)

Türkiye's AD on Chinese foil (extended by Tebliğ 2026/16) did not collapse the Chinese line: China $19.3m (15.4 %, 2017) → $47.0m (24.1 %, 2025). Thailand went $0.0m → $18.6m (9.5 %) and Malaysia $0.4m → $17.2m (8.8 %) over the same span (Comtrade, reporter 792, same query). With China's own line rising, that is not a collapse-plus-surge fingerprint — the Thai plant is selling everywhere, not only around the US order. Malaysia is a watch item, no ownership hop traced.

Transmission chain

Chinese foil/sheet (Dingsheng group) → Thai finishing at Rayong (鼎亨 / Dingheng, est. Sep-2018) → US entry declared "Thailand" → US converters (packaging, HVAC fin stock, battery foil). A Tier-1 score that reads declared country-of-origin sees a US foil book that de-risked from China (50.6 % → 6.4 %). The ownership read says the largest origin by value is a Chinese-parented plant whose output Commerce has already ruled is Chinese foil for duty purposes. That gap is the blind spot.

Method & honesty rails

• Inference, not proof. Commerce's ruling is country-wide and certification-based;

Thai shipments with certified non-Chinese inputs are lawful. No individual entry is asserted to be evasive.

• Korea has named domestic foil producers (Commerce's six-company list), so its surge

is not volume-implausible on its own; it is included because Commerce adjudicated it. India's ×125 surge is unexamined in this wake — no ownership hop traced.

• HS 7607.11/7607.19 ≠ order scope exactly (the scope has thickness and backing

limits); the table is the HS proxy.

• Data lag: 2025 is Comtrade annual as published on 2026-10-06; no 2026 months read.
• Comtrade subscription key was over quota this wake; figures are from the keyless

preview endpoint (≤500 rows/call, sufficient at this granularity).
