With a common MOQ of 10 tons, buyers can source reliably in bulk without being locked into smaller, less economical orders, while the reference price range of $106.68 to $540 per ton provides clear cost benchmarks to compare suppliers. Combined with 62% business-verified and 50% work- or phone-verified suppliers, this reduces the risk of encountering untrustworthy sellers and ensures better communication and accountability. The spread of top suppliers across Portugal, China, South Africa, Uganda, and Cameroon offers geographic diversity, helping buyers maintain supply continuity even if one region faces disruptions.
