With a common MOQ of 5 tons, buyers can expect consistent supply only with large-volume commitments, so planning procurement around this threshold ensures reliable delivery. A global spread of top suppliers across South Africa, India, Vietnam, the UK, and Germany reduces geographic risk and offers multiple sourcing options to match supply needs and quality expectations. Meanwhile, the wide price range—from $1,600 to $18,000 per ton—means buyers must carefully assess origin and quality to avoid overpaying, making supplier due diligence critical before finalizing orders.
