With a common MOQ of just 1 MT, buyers can test suppliers and scale gradually without large financial commitments. The spread of top suppliers across Germany, South Africa, Tanzania, Denmark, and Brazil offers geographic diversity that helps mitigate supply chain risks from regional disruptions. Combined with a wide price range — from $2 to $4,200 per metric ton — buyers must carefully evaluate quality and origin to avoid overpaying, making due diligence essential when choosing a supplier.
