美国采购需求：菜籽蛋白、桦树汁、熊果苷粉、有机绿茶提取物、有机甜菜根浓缩汁、山茶油

I'm exploring the possibility of purchasing your products and would love to get more details on how to place an order. Specifically, I'm interested in understanding the process from start to finish, including any minimum order quantities, payment options, and lead times for delivery. Additionally, it would be helpful to know if there are any discounts for bulk purchases or if you offer customization options. If you could provide me with a catalog or pricing list, that would be great. Looking forward to your prompt response so I can move forward with this potential order!
