The Mining (Local Content) (Amendment) Regulations 2025: What Investors, Contractors, and Foreign Suppliers Must Know

On 12 September 2025, Tanzania published the Mining (Local Content) (Amendment) Regulations 2025, introducing significant updates to the original 2018 Regulations. These amendments reinforce Tanzania’s strategic objective: ensuring that mining-sector value stays within the domestic economy, promotes Tanzanian participation, and strengthens skills transfer.

For foreign and local investors, suppliers, and mining houses, these changes are not cosmetic — they materially affect eligibility, contracting, joint venture structuring, and regulatory approval timelines.

This article breaks down the amendments, explains their impact, and offers practical compliance guidance.

Key Amendments at a Glance

Below is a clear summary of the major regulatory changes introduced by the 2025 amendments:

• Mandatory joint ventures for any foreign-owned supplier, with a Tanzanian company holding at least 20% equity (Reg. 8(6)).
• Publication of an “Exclusive Indigenous Supply List” specifying goods and services reserved for 100% Tanzanian-owned firms (New Reg. 13A).
• Joint venture agreements must be submitted and approved before commencement of mining activities (Reg. 8(7)).
• 50-working-day deemed approval for revised Local Content Plans if no response is received (Reg. 11(8)).
• Two new required sub-plans: Banking Services Sub-Plan and Procurement Sub-Plan (Reg. 12(3)(e–f)).
• Lower threshold (USD 10,000) for reporting sole-sourced mining-related contracts (Reg. 16(1)(a)).
• Clarified definition of “Tanzanian Financial Institution” (Reg. 3).
• New Local Content Committee member: Director of Mineral Audit and Trading (Reg. 5(2)(i)).

Mandatory Joint Ventures for Foreign-Owned Suppliers (Regulation 8(6))

One of the most consequential changes is that any foreign-owned company seeking to supply goods or services to:

• a mining contractor,
• subcontractor,
• licensee, or
• government corporation

must now form a joint venture with an indigenous Tanzanian company that meets the following criteria:

• 100% Tanzanian citizen ownership
• Operates in the same line of business
• Holds at least 20% equity in the joint venture

Exception

This joint venture requirement does NOT apply where the goods or services fall under the exemption list soon to be published under new Regulation 13A.

Practical implication

Foreign suppliers cannot participate in the mining value chain unless they partner with a qualified Tanzanian-owned entity. This intensifies local collaboration and encourages long-term domestic participation.

New Regulation 13A: Publication of “Exclusive Indigenous Supply List”

The Mining Commission is now required to publish a list of goods and services that are:

Exclusively reserved for 100% Tanzanian-owned companies

Publication must be made through:

• The Government Gazette
• The Mining Commission website
• Nationwide print media

This dramatically increases regulatory transparency and allows investors to know, in advance, which business opportunities are restricted to Tanzanian firms only.

Joint Venture Agreements Must Be Approved Before Operations Begin (Regulation 8(7))

Mining companies and suppliers must now submit their joint venture agreements to the Mining Commission before the commencement of mining activities.

Each JV agreement must clearly outline:

• Roles & responsibilities of the Tanzanian partner
• Shareholding structure and equity participation
• Technology transfer strategy and capacity-building commitments

Why this matters

This prevents “paper joint ventures” and ensures genuine local participation, operational involvement, and skill transfer.

50-Day “Deemed Approval” Rule for Local Content Plans (Regulation 11(8))

A major improvement for investors:

If the Mining Commission does not respond within 50 working days after submission of a revised local content plan…The plan is automatically deemed approved.

This amendment reduces administrative bottlenecks and gives companies more timeline certainty.

New Sub-Plan Requirements: Banking Services & Procurement (Regulation 12(3)(e–f))

Companies must now include:

• A Banking Services Sub-Plan
• A Procurement Sub-Plan

within their broader Local Content Plan.

This requirement strengthens oversight on:

• local banking participation,
• financial transactions within Tanzanian institutions,
• procurement transparency.

Lower Threshold for Reporting Sole-Sourced Contracts (Regulation 16(1)(a))

The value threshold for sole-sourced contracts that must be reported to the Mining Commission is now:

Above USD 10,000 equivalent: This is a significant tightening of compliance, requiring mining companies and contractors to monitor procurement value closely and notify the Commission whenever single-source procurement occurs.

Clarified Definition of “Tanzanian Financial Institution” (Regulation 3)

A Tanzanian Financial Institution now explicitly means:

“A financial institution registered in Tanzania under the Banking and Financial Institutions Act.”

This ensures local banking sector participation in mining-sector financial flows.

Strengthening Oversight: New Committee Member Added (Regulation 5(2)(i))

The Director of the Mineral Audit and Trading Department is now part of the Local Content Committee.

This increases:

• technical oversight,
• audit capacity,
• monitoring of compliance and economic impact.

What These Amendments Mean for Investors and Mining Stakeholders

1. Higher Compliance Expectations

Companies must adjust operational planning to include:

• local JV requirements
• sub-plan integrations
• mandatory reporting
• Commission approvals

2. New Barriers to Entry for Foreign Suppliers

Non-Indigenous suppliers must secure a genuine Tanzanian partner with at least 20% equity, and often more de facto influence.

3. Increased Transparency in Local Content Rules

The new “exclusive indigenous list” provides clarity but also restricts participation in certain high-value procurement categories.

4. Faster Approvals and Less Bureaucracy

The deemed-approval mechanism promotes efficiency and reduces investment delays.

5. Greater Opportunity for Tanzanian-Owned Companies

These regulations accelerate domestic participation in mining and supply chains.
