About this record
This page is built from open government-procurement data (Open Contracting / OCDS) for Tanzania. It records a vendor that won public contracts but that we have not confirmed against an official company registry, so it carries no registration number, status, or ownership data, and a deliberately low confidence score. Fylings shows these unverified vendors, clearly labelled, because a complete picture of public spending includes every supplier, not only the ones we can verify. If this vendor is later matched to a registered company, this record is replaced by its verified company page.
