## Summary

A Global Witness investigation (10 June 2026) traced "conflict [coltan](/ko/entity/conflict-minerals)" from
[M23](/ko/entity/m23)-controlled mines around Rubaya in eastern [Drc](/ko/entity/drc) into the supply chains of Microsoft, Apple,
Sony, Amazon, Nvidia, Toyota, Vodafone, LG Display, Ericsson and Honda. The mineral is smuggled into
[Rwanda](/ko/entity/rwanda), relabelled as Rwandan and exported. UN experts estimate >120 tonnes/month crossed
Rubaya-to-Rwanda in 2024 (≥1,400 tonnes within a year), the "largest contamination of mineral supply
chains" in the Great Lakes in a decade. M23 taxes the trade at $4/kg, raising ~$800,000 a month since
May 2024. The ITSCI tagging scheme fails because tags are applied in Kigali; EU 2021 regulation
exemptions for small importers let laundered material through.

## By the numbers

- ~15%, share of world tantalum supplied by the Rubaya mines.
- >120 tonnes/month, coltan smuggled Rubaya-to-Rwanda (May-Oct 2024); ≥1,400 t within a year.
- $4/kg, M23 tax on coltan; ~$800,000/month raised since May 2024.
- 10, major tech/EV brands named as downstream buyers.

## Why it matters

Coltan yields tantalum, essential to capacitors in phones, servers and EVs, so the AI and battery
boom runs partly on a mineral that funds M23's war. The laundering exposes the failure of "conflict-free"
tagging and of EU/US due-diligence rules, and ties the DRC-Rwanda war directly to global tech demand.

## What to watch

- Whether named brands audit suppliers or face EU/US enforcement.
- Reform of the ITSCI tagging scheme and EU Conflict Minerals Regulation exemptions.
- Coltan flows if the DRC-Rwanda peace process or M23 control over Rubaya shifts.

### market / business
- **bne IntelliNews** (Europe, en) — Frames the laundering as a supply-chain due-diligence failure: the ITSCI tagging scheme applies 'conflict-free' tags in Kigali or at the border, so Congolese coltan becomes 'Rwandan,' and EU 2021 Conflict Minerals Regulation exemptions for small importers let it through.

### international
- **Rio Times** (Brazil, en) — Summarises the global tech exposure: Rubaya supplies ~15% of world tantalum, and the smuggling feeds the components of major electronics and EV brands, framing 'blood coltan' as the mineral analogue of conflict diamonds for the AI-and-battery era.
