俄罗斯采购需求：消泡剂、抗泡剂、抗泡剂、食品抗泡剂、油抗泡剂、消泡剂

I'm interested in obtaining a quote for one container of your anti-foaming agent, with the shipping terms being CIF to Saint Petersburg. Could you provide me with the pricing details and any additional information regarding lead times and payment terms? Additionally, I would appreciate it if you could send me a sample weighing between 3 to 5 kg for evaluation purposes. This will help us assess the product's suitability for our needs before making a larger commitment. Thank you for your assistance!
