俄罗斯采购需求：粉末涂料、金属板材、金属零件、金属板材加工、金属加工、硅锰合金

I'm looking to get some detailed information regarding your calcium carbide products. Could you provide me with the price range and any specific conditions associated with purchasing? I'm particularly interested in understanding the quality specifications, packaging options, and minimum order quantities available. Additionally, it would be great to know if you have any special deals for bulk purchases. On another note, I would like to inquire about your payment policies. Do you accept transactions from Russia, and are there any preferred payment methods that you recommend? I'm keen on establishing a reliable sourcing partnership, so your insights on these matters would be invaluable. Looking forward to your response!
