巴基斯坦采购需求：纤维素醚工厂，羟丙基甲基纤维素，HPMC，甲基羟乙基纤维素，MHEC，纤维素醚

I'm interested in sourcing Hydroxy Ethyl Cellulose (HEC) for our operations. Could you provide more details about the product specifications, including pricing, minimum order quantity, and delivery times? Also, I'd like to know if you have any local agents or distributors in Pakistan who can assist with this order. Having a local contact would really help streamline the process and facilitate communication. Looking forward to your prompt response!
