New to Amazon selling — exploring chia seeds & charcoal as potential products

Hi everyone

I’m currently exploring Amazon FBA and considering chia seeds and charcoal as potential products to work with, sourced from South America. I’m still in the early research stage and focusing on understanding feasibility before moving forward.

Right now I’m trying to figure out:

• What are the biggest challenges when selling food products like chia on Amazon?
• How strict are compliance and labeling requirements for these types of products?
• Is charcoal a viable category in terms of logistics and margins?
• What are common mistakes new sellers make when choosing suppliers?

I’m not trying to jump in blindly — just doing proper research and would really appreciate insights from people with experience in this space.

Thanks in advance.
