I'm looking to source zinc sulphate monohydrate for an upcoming project. We need a reliable supplier who can provide this product in bulk quantities. It's essential for us to understand your pricing structure, minimum order quantities, and delivery times. Also, please share any certifications or quality assurance processes you have in place, as we're committed to maintaining high standards in our production. In addition, I'd appreciate it if you could send over product specifications, including purity levels and packages available. If you offer samples, that would be great for our testing purposes. Lastly, please let me know about your payment terms and any discounts for larger volumes. Your prompt response will be highly valued as we're looking to finalize our procurement decisions soon. Thanks!
