台湾采购需求：荧光增白剂、紫外线吸收剂、抗氧化剂

We're looking to source a flame retardant agent that we plan to resell to our clients. Could you provide a quote for 6000 kg of this product? Additionally, we would appreciate details on the expected delivery time and whether a Certificate of Analysis (COA) will be included with the shipment. This information is crucial for our planning and allows us to proceed with our clients confidently. Thank you for your assistance!
