巴基斯坦采购需求：3-o-乙基抗坏血酸、美白、祛斑、个人及家居护理、美白剂

I am in the process of launching my own cosmetic brand and am particularly interested in sourcing a specific ingredient known for its stability and efficacy. To kick off my product development, I'm looking to import an initial quantity of 1 kg for evaluation and testing purposes. Could you please share details on the availability of this ingredient, the minimum order quantities, pricing, and the various shipping options you offer? Additionally, I would appreciate information on the necessary documentation required for a smooth import process into Pakistan. Thank you for your assistance!
