I'm interested in obtaining a detailed quotation for acrylic silicones packed in barrels suitable for a 20-foot container shipment. Please include information regarding the grades you offer, pricing per unit, minimum order quantities, and lead times for delivery. It would be great to also know about the specifications of the products you have available, as well as any certifications or quality standards they meet. Additionally, if you have any options for bulk discounts or seasonal promotions, I would appreciate that info. I'm looking to establish a reliable partnership and would love to understand your payment terms and shipping options too. Looking forward to your detailed response!
