尼日利亚采购需求：食品级CMC、印染级CMC、石油级CMC

I'm interested in sourcing food-grade sodium carboxymethyl cellulose (CMC), specifically for use in food applications. Could you please provide me with detailed information about your product? I'm looking for specifics on the purity levels, potential applications, and any certifications that ensure quality and safety for food usage. Additionally, it would be great if you could include pricing details, minimum order quantities, and lead times for delivery. If there are any product datasheets or relevant specs available, please share those as well. Any information on your company's quality control processes and customer support would also be appreciated. Looking forward to your prompt response!
