What is the Central Supplier Database (CSD)?
The Central Supplier Database (CSD) — operated by National Treasury at supplier.treasury.gov.za — is South Africa's centralised registry of all suppliers who wish to conduct business with government departments, municipalities, and state-owned entities.
Registration on the CSD is compulsory for any business seeking government contracts or tenders above R30,000.
Why Register on the CSD?
