Yes. In a Seller Forums reply, Amazon community manager Ana said flavor, ingredients, and formulation differences fall under the significant-difference side of Amazon’s updated review-sharing policy.
Why does that matter?
Amazon’s original review-sharing announcement says reviews will continue to be shared only when variation differences are minor and do not affect functionality.
If flavor, ingredients, or formulation are treated as significant differences, those variations fall outside the category that Amazon says should continue sharing reviews.
How does this compare to Amazon’s minor-difference examples?
Amazon’s announcement gives examples such as color, pattern, certain size differences, pack quantity, secondary scent differences for non-scent-focused products, and model fitments.
Flavor and formulation are different in kind. In Amazon’s clarification, they are not being treated like cosmetic or packaging-level differences.
Does Amazon explain every edge case here?
No. The Ana_Amazon reply is useful because it answers a narrow seller question clearly, but it still sits inside a forum clarification rather than a longer policy memo.
The safe takeaway is narrow: Amazon has publicly indicated that flavor, ingredients, and formulation belong on the significant-difference side of the updated review-sharing rules.
