菲律宾采购需求：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 looking to source blue dye in sufficient quantities to cover approximately 1 hectare of material. Could you provide details on the available options, including color fastness, application methods, and any bulk pricing discounts? Also, I'd appreciate information about lead times for delivery and whether you offer any samples for quality testing before committing to a larger order. In addition, please let me know about the minimum order quantities and payment terms. If there are specific certifications or safety data sheets available for the blue dye, including those in your response would be helpful. I'm keen to find a reliable supplier that can meet these requirements efficiently, so any relevant details would be much appreciated. Looking forward to your prompt response!
