乌克兰采购需求：产品

I'm looking to source Buchu leaf powder and would like to gain a better understanding of your offerings. Can you provide me with your pricing details for various quantities? I'm particularly interested in bulk purchase options, as I aim to place a substantial order. Additionally, it would be helpful if you could share any information on the quality of your Buchu leaf powder, including sourcing and any certifications you may have. Understanding your lead times and shipping costs would also be beneficial. I'm eager to establish a mutually beneficial partnership, so any further insights you can share would be greatly appreciated.
