I'm interested in becoming a distributor for your products and would love to know more about the requirements. Specifically, I want to understand any certifications, minimum order quantities, and pricing structures that I need to be aware of. Additionally, it would be great if you could provide some insights into your shipping and return policies, as well as marketing support that may be available for new distributors. Looking forward to your response!
