Russia's defence trade has collapsed in categories it cannot domestically replace — and surged in categories that expose the limits of sanctions. Mirror trade reconstruction across 247 countries reveals a supply chain under sustained structural pressure, with rerouting visible in the flows that self-reported data deliberately obscures.
Russia stopped reporting its own trade to UN Comtrade in February 2022. The Kremlin's calculation was straightforward: remove the data, obscure the supply chain, frustrate the analysts. What the calculation missed is that every country Russia trades with still reports — and their records, inverted and reconstructed, tell the full story.
Valan Sentinel's mirror trade intelligence layer covers 247 countries and $787 billion in implied defence-relevant trade value. Every row derives from a transaction reported by a national customs authority. Russia's 15,300+ reconstructed records represent one of the most analytically significant datasets in the platform — precisely because Russia chose silence.
Russian military aviation is the single most visible casualty of the sanctions regime in the trade data. Aircraft imports — HS chapter 88, covering military and dual-use aviation platforms, components, and systems — peaked at $6.95 billion in 2021. By 2023, the same flow had fallen to $76 million.
This is not a data artefact. The collapse is visible from multiple independent reporting countries — Germany, France, the Netherlands, Japan, Korea — each filing its own customs records and each showing the same cliff edge in early 2022. The mirror methodology, which aggregates partner-reported flows and inverts them to reconstruct the non-reporting country's position, is conservative: only direct import and export flows are used, excluding re-exports that carry higher uncertainty.
What does a 94% collapse in aircraft imports mean operationally? Russian military aviation maintenance, platform production, and avionics replacement all depend on supply chains that ran almost entirely through Western manufacturers. Controlled components — turbine blades, flight management systems, precision guidance electronics — cannot be domestically substituted on a two-year timeline. The procurement gap is structural, not temporary.
The 94% collapse in Russian aviation imports represents the most complete validated supply chain disruption visible in the Sentinel trade data. It is reconstructed not from estimates, but from the customs filings of Russia's actual trading partners — each an independent, official primary source.
Kazakhstan is the most prominent node in Russia's visible rerouting architecture. Sentinel's mirror trade data identifies a $9 billion rerouting signal — imports flowing into Kazakhstan at volumes and in categories (military electronics, dual-use components, precision machinery) inconsistent with Kazakhstan's own defence industrial base and domestic consumption profile.
The rerouting signal is not a suspicion. It is a mathematical residual: the difference between what Kazakhstan reports importing and what Kazakhstan's GDP, defence budget, and industrial capacity can absorb. The gap is the signal. When Kazakhstan reports importing military electronics at volumes that exceed its entire declared defence budget, the destination is not Kazakhstan.
"Russia stopped reporting its own trade. Every country it trades with did not. The mirror is exact."
The methodology here follows established practice. UN Comtrade uses mirror statistics to fill gaps where countries do not report. SIPRI uses partner-reported data to estimate arms transfers for non-reporting states. The CSIS China Power Project applies the same technique to Chinese military trade analysis. Sentinel automates and scales this methodology across 247 countries with daily updates.
| Category | Flow | Signal Type | Key Indicator | Implication |
|---|---|---|---|---|
| Military Aircraft (HS 88) | Imports | −94% collapse | $6.95B → $76M | Aviation MRO chain severed |
| Military Electronics (HS 85) | Imports via KAZ | Rerouting | $9B+ signal | Dual-use component bypass |
| Nuclear / Fissile (HS 28) | Exports | 3× surge | $6.2B | Revenue offset, leverage signal |
| Strategic Materials (HS 81) | Exports to CHN | New dependency | Accelerating | Structural eastward pivot |
The most counterintuitive signal in the Russian mirror trade data is not the collapse — it is the surge. Nuclear exports, classified under strategic materials in the Sentinel HS categorisation, tripled in the post-sanctions period, reaching $6.2 billion. This is not a violation of the sanctions regime: civilian nuclear supply contracts — enriched uranium for European and Asian reactors — remained outside the initial Western sanctions architecture, and Russia moved aggressively to monetise that carveout.
The signal carries two implications. First, it partially offsets the economic pressure of sanctions through hard currency revenue from a captive market — European utilities contractually dependent on Russian fuel supply could not unwind those contracts immediately. Second, it is a coercive leverage instrument: the export surge is also a reminder of dependency.
The nuclear export surge represents Russia's most effective sanctions arbitrage. Civilian nuclear contracts, initially outside Western sanctions architecture, provided a revenue offset as aviation and electronics imports collapsed. Niger's post-coup uranium export flows ($3.7B reconstructed from EU partner reporting) add a second dimension to the nuclear supply chain story.
Every country that does not self-report to UN Comtrade — or reports selectively — has its defence-relevant trade flows reconstructed in Sentinel using the mirror statistics methodology. When Germany reports importing aircraft components from Russia, that transaction appears in Sentinel as Russia exporting aircraft components to Germany. The original_reporter_iso3 field preserves full provenance for every row.
The reconstruction is conservative. Only direct imports (M) and direct exports (X) are mirrored. Re-exports and re-imports, which carry higher uncertainty about ultimate origin and destination, are excluded. All trade values are converted to USD at period exchange rates using the filing country's reported currency — no estimation is applied to values.
Known limitations: transit trade where goods pass through intermediaries may be attributed to the transit country; classification differences between reporter and partner create occasional commodity-level mismatches; timing differences affect monthly but not annual aggregates. The original_reporter_iso3 field enables analysts to weight rows by reporter quality and apply their own judgement on these factors.

For event-driven and systematic macro strategies, the mirror trade data offers something specific: a quantitative, source-verified, daily-updated signal on the operational sustainability of Russia's defence effort — disaggregated by category, by trading partner, and by HS commodity.
The aircraft import collapse signals structural degradation in air superiority capability on a timeline that cannot be reversed by policy decision alone. The electronics rerouting signal, visible in Kazakhstan and several other Central Asian intermediaries, indicates that workarounds exist but are constrained in volume and sophistication. The nuclear export surge signals that Russia is actively converting its remaining leverage into cash — a behaviour consistent with a state under sustained economic pressure optimising for near-term revenue.
None of this is visible in Russia's own reporting. All of it is visible in the records of Russia's trading partners. Sentinel reads both sides of every transaction — the one that is reported, and the one that is not.
Russia chose silence. The data did not.
