It would be great if you could provide specifics regarding the available grades, sourcing methods, and production capacities.

Additionally, I'd like to know your pricing structure, including any bulk order discounts that might apply. If you have a standard lead time for delivery, kindly share that as well. Understanding your payment terms and shipping options would be greatly beneficial, too. Looking forward to your prompt response with the details so we can move forward efficiently!
