美国采购需求：高铝耐火水泥，耐火浇注料

I am reaching out to inquire about your refractory cement with an alumina content greater than 70%. I'm looking for a total of 6 kg packs, amounting to a bulk order of around 6150 kg. Could you please provide me with pricing details, availability, and lead times for this order? Additionally, any information on your product specifications and quality certifications would be greatly appreciated. Looking forward to your prompt response!
