I'm interested in purchasing black silane and would like to know your pricing per pack. Additionally, I'm looking to buy a surplus of 30 metric tons. Could you please provide me with your best rates and any available bulk discounts? I'm also curious about the lead time for this quantity and whether you can guarantee timely delivery. Furthermore, if there are different packaging options or any specific terms and conditions I should be aware of, that info would be helpful. Please let me know if you need any further details from my side to facilitate this inquiry. Looking forward to your prompt response!
