埃塞俄比亚采购需求：萘系高效减水剂，yl-snf-a（Na2SO4 < 5%）

I'm interested in sourcing a specific type of product, specifically SNF in a 25 kg packaging. I would like to inquire about the availability, pricing, and any minimum order quantities you may have. It's important for me to understand the lead times for delivery as well, as this can impact my overall planning. Additionally, please provide information on the product specifications, including any certifications or quality assurances you can offer. If there are different grades or variations available, I'd appreciate details on those too. I'm looking to establish a reliable supply chain, so your prompt response would be greatly appreciated.
