With 100% of suppliers phone-verified, buyers can confidently reach out to suppliers with verified contact details, minimizing the risk of unresponsive or fraudulent sellers. This is especially valuable in a category like bitumen where supply chains are complex and trust is critical. While prices vary widely between 0.52 and 0.90 per kilogram, the presence of suppliers across South Africa, Kazakhstan, the U.S., Russia, and Iran offers buyers multiple sourcing options to match their supply needs and risk tolerance—so they can choose based on cost, delivery reliability, or regional stability.
