I'm looking to source powdered pepper from your factory in China and would love to get more details on what you offer. Specifically, I'm interested in the product specifications, including the various grades you produce, as well as any certifications or quality assurance measures you have in place. Additionally, please share your pricing options, including bulk purchase rates and any discounts available for larger orders. I'm also keen to understand the shipping options you provide for distribution in Ghana, including timelines and logistics involved. Your prompt response would be appreciated!
