With a common MOQ of 12 tons, buyers in this category are typically large-volume industrial users who need scalable, long-term supply agreements—so sourcing decisions should focus on volume stability and cost predictability. The spread of top suppliers across India, China, Thailand, Indonesia, and Spain offers competitive pricing and regional flexibility, while the wide reference price range (6,700–40,000 / ton) means buyers must carefully assess quality and origin to avoid overpaying. However, only 33% of suppliers are phone-verified, which increases the risk of unverified claims and weakens due diligence—so buyers should prioritize suppliers with clear, verifiable contact and transparent pricing to reduce sourcing risk.
