I'm reaching out to request a detailed quotation for food-grade Calcium Carbonate DC granules suitable for tablet production. We're looking to purchase a quantity of 5 tons. Could you please provide your best pricing options, including any bulk discount possibilities? Additionally, it would be helpful to know about the specifications of the product, such as its purity levels, packaging options, and lead time for delivery. If you have any certificates or test reports available, please share those as well. Looking forward to your prompt response with the required information. Thanks!
