With a common MOQ of 61 MT, buyers must commit to substantial volume to access competitive pricing, meaning they need to plan procurement around large-scale demand. The wide reference price range of 28.8–2000.0 / MT—spanning nearly 70x—shows that cost varies dramatically by supplier, quality, and origin, so buyers must verify supplier credibility and negotiate terms carefully. Combined with a global supplier base across Tanzania, South Africa, Thailand, Poland, and the U.S., buyers gain flexibility in sourcing from diverse regions, but must also manage the risk of price volatility and inconsistent quality without clear benchmarks.
