美国采购需求：食用明胶、药用明胶、胶原蛋白、胶原蛋白肽、明胶片、果冻胶

I'm looking for reliable suppliers to provide solar house systems tailored for residential projects. We aim to purchase a variety of configurations to enhance energy efficiency and sustainability in homes. Could you share your product catalog, including specs, pricing, and bulk order discounts? Additionally, I'd love to know your production capacity and lead times, as we are planning to scale up our procurement. Looking forward to your prompt response!
