With suppliers spread across India, Iran, Sri Lanka, the U.S., and Ecuador, buyers gain access to diverse production cycles and regional cost advantages, reducing reliance on any single source. However, the lack of standardized payment terms—only 'Other' is common—means buyers must carefully vet each supplier’s financial credibility to avoid payment risks. Combined with a clear price range of 2400–4200 / ton, this gives buyers a reliable benchmark to evaluate value and negotiate terms confidently.
