Local content is now one of the biggest topics in Tanzania's mining sector. The chairman of TAMISA (the Tanzania Mining Industry Suppliers Association), Peter Kumalilwa, has said the association keeps receiving reports that some mines sidestep local suppliers or set procurement terms that shut them out, and that TAMISA will report violators to the authorities. At the same time, the government has set a 90% local content target for mining procurement. In 2025, mining-related procurement reached about TZS 5.35 trillion, of which roughly TZS 4.6 trillion (about 86%) went to local companies.

Here is what has changed on the ground:

• Regulation 13A: 20 categories of goods and services are reserved for 100% Tanzanian-owned companies, in force since 15 November 2025. The list includes haulage and logistics, camp management and catering, legal services, vehicle hire, and chemicals and reagents.
• Stricter verification: the Mining Commission has said it will look beyond registration papers at actual ownership, management control and operational capacity.
• Reporting: licence holders must submit local content plans and performance reports to the Mining Commission, and must inform it about proposed contracts and purchase orders.
• Foreign suppliers: a non-indigenous company supplying a mine generally needs a joint venture with a 100% Tanzanian-owned company in the same line of business, with at least 20% local equity.

The practical problem is simple to state and hard to solve in spreadsheets: for every purchase order, who is the vendor (100% Tanzanian, joint venture or foreign), is the item in a reserved category, and what does it add up to for the quarter? The same question applies to jobs: how many people on site are Tanzanian, and in which roles?

On Odoo, a mine site, a mining contractor or a mining supplier can handle this inside the normal workflow instead of a month-end clean-up:

• Vendor classification: every vendor carries an ownership class and supporting documents, so each purchase order inherits it automatically.
• Spend by category: purchasing reports show spend by vendor class and by reserved category, against a target such as 90%.
• Inventory and spares: multi-warehouse stock for spares, consumables, fuel and reagents, with batch tracking and reorder rules.
• Machines and fleet: asset registers with preventive maintenance, breakdown history and cost per machine.
• People: employee records, attendance, rosters and payroll, with reporting on local employment.
• Project and cost control: costs tracked per pit, per contract or per site.

Some mining-specific needs, such as tonnage and grade tracking or regulated-item controls, usually need tailored development on top of Odoo, and remote sites need a plan for weak connectivity. We think that is better said openly than hidden.

Question for the community: If you run a mine site, work as a mining contractor, or supply the sector, how do you prove local content today: spreadsheets, a procurement system, or manual reports to the Commission? And which part is hardest: classifying vendors, tracking reserved categories, or employment data?
