白俄罗斯采购需求：营养技术、生物技术、RiviK2、维生素 K2 MK-7、食品矿物质、γ-氨基丁酸

I represent Globalchim, a company focused on importing feed additives from China to Belarus. We're currently looking to procure feed-grade Zinc sulfate, Manganese sulfate, and Ferrous sulfate monohydrate. Please send your best FOB pricing for a minimum order of 1 container (27 tons), including packaging in 25 kg bags. Additionally, it would be great if you could provide a certificate of analysis for these products. Looking forward to your prompt response as we aim to move quickly on this order. Thank you!
