Is the ban leaking? Dual-use microelectronics and machine tools into Russia

Trade-flow companion to the price wedge (R72). This is a DUAL-SCORE / alternative-track signal — never folded into any Tier-1 exposure score. The divergence between "who the controlling state says it stopped selling to" and "who suddenly started buying" IS the signal. Research, not investment advice; diversion is inferred from statistical implausibility plus the named public enforcement record, never asserted as smuggling on any individual shipment.

Live chart + method: [/situation-room → "Is the ban leaking?"](/situation-room).

Verdict

The corpus's second mode-E case (end-user falsification / pass-through purchaser), and it overturns the pessimistic conclusion the first one reached.

The [advanced-AI-accelerator case](2026-ai-accelerators-us-export-controls-circumvention-transshipment.md) filed at GATE 0 with a structural excuse: in mode E nothing is relabelled, what is falsified is the end-user declaration — a field that exists in no customs series anywhere — so instances surface "through criminal process, not data."

That conclusion was too strong. It was a property of that instance, not of the mode. Here the same mode runs on the same geometry — a controlling state (US/EU) restricting who may receive its own export, a pass-through purchaser taking lawful delivery and re-shipping — and the corridor is plainly legible in two free official customs datasets, on both legs, because the pass-through jurisdiction is small enough that the diverted volume dominates its national trade line.

The corrected rule is about signal-to-noise, not mode:

> Mode E is detectable when the diverted volume is large relative to the > pass-through jurisdiction's own baseline demand, and invisible when it is > small. Singapore and Malaysia absorb billions in genuine data-centre buildout, > so a diverted tranche disappears into the noise. Kyrgyzstan bought €4,655 > of EU metal-cutting lathes in all of 2021. There is nowhere for €4.0 million > to hide.

Leg 1 — the controlled origin's exports re-flag onto three small neighbours

The controls: US BIS placed Russia/Belarus under the EAR's Russia FDP rule from 24 February 2022, and on 18 April 2024 expanded that perimeter to the entire Common High Priority List (CHPL) — the HTS-6 list built jointly with the EU, Japan and the UK of items recovered from Russian weapons in Ukraine, covering commercial-grade integrated circuits, RF transceiver modules, electronics test and manufacturing equipment, and CNC machine tools (filed action 2024-04-18-us-bis-ear-iran-aggression-russia-fdp-chpl-expansion).

EU27 exports, €m, of four HS lines that map onto those CHPL categories:

Source: Eurostat Comext, dataset DS-045409 ("EU trade since 1988 by HS2-4-6 and CN8"), reporter EU27_2020, flow = exports, indicator VALUE_IN_EUROS, pulled from the free dissemination API. `na` = no reported trade.

The controlled line does not just fall, it terminates: EU integrated-circuit exports to Russia go from €622m to €29,000 — a 99.995% collapse. The four lines above together fall from €2,058.9m (2021) to €2.8m (2025), treating the two na lathe years as zero.

And the surges land on the three smallest, most implausible neighbours:

• Kyrgyzstan, HS 8542: €62k → €3.71m — 60×.
• Kyrgyzstan, HS 9030: €147k → €2.52m — 17×.
• Kyrgyzstan, HS 8458: €4,655 → €3.995m — ~860×. This is the single most

implausible figure in the R72 corpus.

Kyrgyzstan has no semiconductor industry, no electronics OEM, and no machine-tool sector. Its EU intake on these lines was flat and trivial for the three years before the control and returned toward trivial after enforcement (below). A step-change of that shape, in exactly the product categories a named export-control list identifies, in exactly the window the control took effect, is the volume-implausibility fingerprint — with the denominator being absorptive capacity rather than production capacity, as mode E requires.

The monthly series dates the corridor

EU27 → Kyrgyzstan, HS 8458 (lathes), monthly, €:

The corridor does not exist before the control, stays dark for the first five months of the war, and switches on in July 2022 — the standing-up lag of a procurement route, not a demand trend.

Leg 2 — the pass-through re-exports, in its own numbers

Kyrgyzstan's own reported exports of HS 8542 (integrated circuits) to Russia:

Source: UN Comtrade, free public preview API (reporter 417 Kyrgyzstan, partner 643 Russian Federation, flow X = exports, HS 8542, customs code C00, all modes of transport).

A ~2,300× increase in a product Kyrgyzstan does not make. The country reported under six thousand dollars of integrated-circuit exports to Russia in 2021 — consistent with a nil industry — and thirteen and a half million dollars two years later. Both legs of the chain are therefore visible in official data published by the transit state itself and by the origin bloc, with no reliance on the falsified field.

One honest note on the arithmetic: the EU supplied roughly €3.7m (~US$4.0m) of Kyrgyzstan's US$13.5m re-export that year — under a third. The balance entered from origins not traced in this case. The EU leg is the high-specification sliver of the corridor, not its bulk; that is also why the test-equipment (9030) and machine-tool (8458) lines matter more analytically than their small euro values suggest.

The corporate pipe — one legal person, three flags

The mode-A template's ownership tell was a name-root chain (Guangxi Youngsun → Thai Unipet → Youngsun & Essen). The mode-E analogue is stronger and comes straight from a primary enforcement instrument.

On 27 August 2024 BIS added to the Entity List:

> All Global Trading Elektronik Dis Ticaret Ltd Sti, under the destinations > of Kazakhstan, Kyrgyzstan and Turkey — Auezova 14a, BC "Fertility", 15th > floor, Almaty; 140/57 Chui Street, Bishkek; and three Istanbul/Antalya > addresses, each entry cross-referencing the others as "alternate addresses."

BIS designated it a Russian Procurement Entity under §734.9(g) with a footnote 3 designation, in a group described as "connected to transshipment networks involved in sending sensitive U.S.-origin technology to Russia."

Source: Federal Register, "Revisions to the Entity List," FR Doc 2024-19130, published 27 August 2024 — full text at https://www.federalregister.gov/documents/full_text/text/2024/08/27/2024-19130.txt

One company. Three jurisdictions. Cross-referenced addresses in the listing itself. The corridor is not three national trade relationships that happen to have grown; on at least this hop it is a single legal person holding a registered presence at each waypoint — the same structural workaround as the antimony case, where each entity obeys its own jurisdiction's law and the corporate structure is the evasion.

Two earlier listings tie the specific product categories to specific Bishkek firms:

• 27 February 2024 (FR Doc 2024-03969): Muller Markt LLC (43 Fatyanova

St. and 95 Kalyk Akiev St., Bishkek) and Profflab LLC (179 Toktogul St., Bishkek), added for "procuring U.S.-origin machine tools, electronics test equipment, and machine tool spare parts for Russian end-users without required BIS licenses."

• 19 May 2023 (FR Doc 2023-10684): Tro.Ya, LLC (Tokmok and Bishkek),

added under §744.11(b) for both obstructing an end-use check and "posing a risk of diversion of items subject to the EAR to Russia"; Medisar, LLC (4/9 Getari St., Yerevan) added under Armenia the same day.

The BIS wording on the February 2024 pair — machine tools and electronics test equipment — names precisely the two HS lines (8458 and 9030) that show the sharpest Kyrgyz surge in Eurostat's data. The statistical fingerprint and the enforcement record point at the same two product categories, in the same country, in the same window, derived independently.

The enforcement arc — and the rotation

This is the first R72 case where a control demonstrably bit, with a date.

Kyrgyzstan's EU intake collapses after the February 2024 listings and the April 2024 CHPL/FDP expansion: HS 8542 €3.71m → €0.47m → €0.31m (−92% from peak), HS 8458 €3.995m → €0.11m (−97%), HS 9030 €2.52m → €0.78m (−69%). The corridor that switched on in July 2022 was substantially switched off inside two years of the first designation.

But it did not stop — it moved. EU27 → Kazakhstan, HS 8458, monthly, €:

Source: Eurostat Comext DS-045409, freq = M.

Kazakh annual intake of EU lathes goes €0.705m (2021) → €42.7m (2024), ~60×, with the step change beginning May 2024 — after Bishkek's two machine-tool procurers were listed in February 2024 and after the CHPL FDP expansion in April 2024. The sequencing is consistent with corridor rotation: enforcement displaced the route from Bishkek to Almaty rather than closing it.

And leg 2 moves with it. Kazakhstan's own reported exports of HS 8458 to Russia:

Source: UN Comtrade free public preview API (reporter 398 Kazakhstan, partner 643 Russian Federation, flow X, HS 8458, customs code C00).

29×, in the same year the EU intake went 60×. Both legs of the rotated corridor are visible, in the same datasets, one year after both legs of the original corridor went quiet.

One rail on this leg: unlike Kyrgyzstan, Kazakhstan has a genuine machine-building sector and a real industrial-modernisation programme, so its absorptive denominator is not zero and a share of both the intake and the re-export is plausibly legitimate. The claim here is therefore narrower than the Kyrgyz one — not "this volume cannot exist," but "this volume stepped by an order of magnitude, on a listed product category, in the quarter after the previous corridor was enforced against, and its onward line to the controlled destination stepped with it."

Why it matters for the buyer

1. A collapsed bilateral line is not a severed dependency. An EU exporter reading "we no longer ship to Russia" is reading the wrong series. The question is what its distributors ship to jurisdictions whose absorptive capacity cannot explain the order — the same correction the antimony case makes for origin, applied to destination. 2. The obligation is already personal. From 20 March 2024, Article 12g of Council Regulation 833/2014 — the "no re-export to Russia" clause — requires EU exporters selling or transferring listed goods to a third country to contractually prohibit their counterparty from re-exporting to Russia or for use in Russia (European Commission FAQ). In parallel, BIS's §734.9(g) Russian-Procurement-Entity designations reach foreign-made items. An exposure model that stops at the first-tier customer country misses the entire risk surface — and the diligence duty now sits on the exporter, not the regulator. 3. Enforcement moves the corridor, not the volume. The Bishkek→Almaty rotation is the actionable pattern: a counterparty screen calibrated on last year's diversion hub is structurally one enforcement round behind. The monitorable is the derivative — which small-baseline jurisdiction is currently posting a step change — not the level. 4. It repairs the mode-E detector. The corpus can now say when a reverse-direction control is auditable from public data (small pass-through, large diverted volume) and when it is not (large pass-through with genuine demand cover). That is a scope rule for the whole mode, not a one-off finding.

Method & honesty rails

• Trade data: Eurostat Comext DS-045409 (EU27_2020 reporter, exports, values

in EUR, annual and monthly) and UN Comtrade free public preview API (Kyrgyz reported exports, values in USD). The two legs are in different currencies and are never summed. Comext values are trade values, not quantities; HS 4-digit headings are broader than the CHPL's HTS-6 entries, so these lines contain non-CHPL goods too.

• Inference, not accusation: diversion is inferred from a step change against

a jurisdiction's own multi-year baseline, in product categories a named control list identifies, in the control window — corroborated by named Federal Register designations. No individual shipment is asserted to be illegal, and no company beyond those already named in the cited Entity List instruments is implicated. Entity List designation is an administrative licensing action, not a criminal conviction.

• Alternative-track only: this never touches buyerRelativeScore or any base

exposure score. It sits beside them, exactly like the China–West price wedge.

• Known gaps: (a) Kyrgyzstan reported no HS 8458 exports to Russia for

2023 in Comtrade, so the lathe corridor's leg 2 is closed for Kazakhstan but not for Kyrgyzstan — absence of a reported line is not evidence of absent trade, and is not treated as either; (b) Armenia's surge is reported but not separated from genuine growth (relocated tech firms, real import substitution) and is not claimed as diversion here; (c) the EU supplies under a third of the Kyrgyz re-export, so the majority feeder origin is untraced; (d) Russia stopped publishing detailed customs data in 2022, so the destination-side mirror that would close every leg does not exist.

• Generalises: the mode-E detectability rule — *diverted volume relative to

pass-through baseline demand* — is the reusable output. Apply it before concluding a reverse-direction control is unauditable.
