Hello from Amazon Selling Partner Support,

We understand your concern about requesting a reimbursement for your FNSKU mismatch under the order 113-3080286-6400264.

Upon checking, the refund was issued in June 14, 2025 which is not within statute of limitations. As result we are unable to process a reimbursement request at this time.

Please be informed that FBA Customer returns claim window differs between the US store and the CA, BR, and MX stores. For US, claims may be submitted no earlier than 60 days after the customer refund or replacement date and no later than 120 days after. For CA, BR, and MX the claim window is between 45 to 105 days.
