I'm looking for high-quality sulfur with a purity of 99.95-99.98%. The total order quantity is 5000 tons, and I would appreciate it if you could provide your best price for this volume. As a target, I'm aiming for a range of $25-30 per ton, so if you can meet or get close to that, it would be great. Additionally, I would prefer to communicate via WeChat or WhatsApp for quicker discussions. You can reach me at 8981 778 08 17. Looking forward to your prompt reply with your pricing and any relevant details!
