## ARTICLE

Tanzania is fundamentally rewriting its critical minerals playbook. Rather than exporting raw ore to overseas refineries—a model that bleeds 60–70% of potential value—the East African nation is now mandating domestic value addition across cobalt, tanzanite, gold, and rare earth elements. This pivot carries immediate implications for global supply chains, battery makers, and investors betting on Africa's industrial maturation.

The strategy reflects a hard lesson learned over two decades. Tanzania holds some of the world's richest cobalt reserves (estimated 3.8 million tonnes proven), yet exported 95% as raw concentrate through the 2010s. A single tonne of cobalt ore—worth $8,000–$12,000 raw—becomes $45,000–$60,000 when refined domestically and $120,000+ in downstream alloys or cathode precursor materials. Tanzania captured only the lowest rung. China, meanwhile, processed Tanzanian ore and sold refined products back to African EV manufacturers at 300–400% margins.

## Why Are African Nations Suddenly Enforcing Local Processing?

The cobalt crunch of 2021–2023 exposed supply chain fragility. When Democratic Republic of Congo (Tanzania's western neighbor and world's largest cobalt producer) restricted exports, global battery makers panicked. Tanzania realized it could anchor a full supply chain—mining, refining, precursor manufacturing, and cathode production—within East Africa. Rwanda and Zambia launched similar programs simultaneously. The message to investors is clear: the era of "dig and ship" is ending.

Tanzanian policy now includes:
- **Mandatory 30% domestic processing by 2027** for all new mining licenses
- **Tax incentives** for refineries and secondary processing plants (5–10 year holidays)
- **Joint venture requirements** pairing foreign miners with local processors
- **Reserve land** allocated for battery cathode factories (targeting 2026 commissioning)

These aren't suggestions. In late 2024, the government suspended two exploration permits for companies refusing to pledge processing capacity.

## What Does This Mean for Battery Markets and EV Supply Chains?

Tesla, CATL, and LG Energy are already signaling interest in Tanzanian precursor sourcing. A single gigafactory requires 10,000+ tonnes of cobalt annually. If Tanzania controls 40–50% of global cobalt *processing* by 2028 (from current 5%), spot prices stabilize—and African refiners capture $8–12 billion annually in margin that previously flowed to Asian intermediaries. For investors, this creates a 15–20 year secular opportunity in midstream processing, not just mining.

The risk: execution. Tanzania's power grid is strained; many proposed refineries need dedicated 300+ MW plants. Lead times are 3–4 years. Political instability or commodity price crashes could stall projects mid-build.

## When Will Processing Plants Become Operational?

First-phase refineries (cobalt and nickel) are expected by Q3 2026. Cathode precursor facilities follow 2027–2028. These timelines assume stable financing and no regulatory reversals—not guaranteed in a continent where mining policy shifts with elections.
