With a common MOQ of 100 MT, buyers must plan for large-volume commitments, making it essential to partner with suppliers who offer flexibility or have proven capacity to meet such demands. The mix of suppliers from major mining nations and industrialized countries provides access to both cost-competitive raw materials and reliable quality control, while 50% phone-verified suppliers offer real-time, direct validation—critical for confirming material authenticity and delivery timelines in a high-risk category. Combined with a wide price range, buyers must prioritize supplier verification and material specifications over price alone to avoid costly misalignments.
