I'm looking to place an order for 5 tons of MAXGOLD. Could you please provide me with the pricing details, lead time for delivery, and any bulk purchase discounts you might offer? Additionally, I'd appreciate information regarding payment terms and shipping options available, as well as any minimum order requirements. If possible, I would also like to know about the product's specifications and any certifications it holds. Understanding these details will help me make a more informed decision. It would be great if you could send me a catalog or a data sheet if available. Looking forward to your prompt response, as I'm keen to move forward with this order soon.
