I'd like to inquire about the process for supplying you with the necessary raw ingredients. Specifically, I'm interested in understanding your preferred methods of delivery, lead times, and any specific requirements you might have for the materials. Additionally, it would be helpful to know if there are certain certifications or documentation needed for the ingredients we provide. I'm eager to ensure a smooth collaboration and would appreciate any details that can help streamline the supply process. Thanks!
