印度采购需求：硫化蓝BRN、液体硫化黑4GN、硫化黑BR 200%、靛蓝、罗丹明B、孔雀石绿（无铅）

I'm reaching out to inquire about a specific dye that I'm interested in for my upcoming projects. I'm looking for detailed information on the product, including technical specifications, available grades, and any potential applications. Additionally, I would like to know about your pricing structure, minimum order quantities, and packaging options available for shipment. Could you also provide insight into the lead times for orders and whether you have any certification or compliance data? Understanding these aspects will help me make an informed decision. If there are any samples available, that would be great as well. Looking forward to your prompt response on this.
