I submitted same invoices that I used for ungating in the first place but doesn’t seem to satisfy Amazon requirements.
Do they require LOA for every brand now?
Re-ungating a brand you were previously approved for is often harder than the original ungating because Amazon now treats it as a fresh compliance review rather than a reinstatement, which is why resubmitting the same invoices frequently fails. In many cases, especially with prestige or tightly controlled brands like Aveda, Amazon now expects stronger proof of authorization and invoices alone are no longer sufficient, even if they were accepted in the past.
Practically speaking, this often means a current Letter of Authorization from the brand itself or from an officially authorized distributor that explicitly allows you to sell the brand on Amazon, combined with recent invoices that match your seller account details exactly.
Amazon has tightened enforcement across gated brands, so while an LOA is not formally required for every brand, it is increasingly required in re-gating scenarios where the system flags brand control or authenticity concerns.
Your best path is usually to secure a fresh LOA and submit it together with compliant invoices in a new approval request rather than reusing older documents.
