Error 100640 — Brand not allowed for category

The brand value you submitted isn't permitted in your selected category — typically because the brand has a known association with a different category or has been gated.

Amazon cross-checks brand-category pairs to prevent counterfeit listings. If 'Apple' is submitted in 'Hardware Tools' category, Amazon flags as suspicious.

1. Verify your category is correct — most brand-category mismatches are actually category errors.
2. If you genuinely sell branded items in an unusual category (e.g., licensed Disney bedding in Bath), contact Amazon to whitelist the brand-category pair.
3. If you're a generic seller mistakenly using a known brand name, switch to your actual brand or 'Generic' (where allowed).
4. Resubmit after correction.

• Using common words as brand names that conflict with major brands ('Apple' for non-tech products)
• Listing unauthorized cross-category items
