I'm reaching out to request detailed information and a quotation for black pigment suitable for our upcoming projects. We're particularly interested in aspects such as specifications, available grades, packaging options, and any certifications your product may possess. Additionally, it would be great to know your lead times and minimum order quantities to help us plan accordingly. Could you also provide insights on pricing tiers, including bulk purchase discounts, if available? We're looking to establish a long-term supply relationship, so any information on your production capabilities and quality control measures would be appreciated as well. Looking forward to your prompt response with all the necessary details!
