Amazon Customized FBA Return Grading: A Seller Setup Guide
A concise guide to customized grading rules, evidence-based criteria, and controlled pilots for FBA Grade and Resell.

Amazon lets eligible sellers provide customized guidance for returned inventory processed through Grade and Resell. The feature can encode product knowledge, but Amazon's standard grading process still applies. That makes objective criteria and measured pilots more useful than broad assumptions.
What Amazon Customized Grading Changes
Sellers can provide guidance about seals and packaging, included accessories, authenticity, device capabilities, and other requirements. Amazon says rules can cover specific ASINs, all ASINs, or a bulk CSV.
ASINs without customized guidance use Amazon's default criteria. Customized guidance supplements Amazon's process; it does not guarantee a grade or disposition.
Write Evidence-Based Grading Criteria
Describe observable conditions an independent operator can apply consistently. Identify the item, exact component or capability to inspect, acceptable and unacceptable states, intended recovery treatment, supporting product evidence, and review owner.
Amazon says only one rule can exist per category for an ASIN and a new rule replaces the existing one. Preserve prior wording and effective dates outside the live rule.
Launch With a Controlled Pilot
Amazon directs sellers to Settings, Orders, Recovery, then Customized grading. Start with a small ASIN cohort, save the baseline, check for category conflicts, define the intended Restore to New or Sell as Used treatment, and assign an exception owner.
Measure observed recovery and downstream customer signals while accounting for product mix, return reasons, seasonality, pricing, and Amazon's standard grading process.
FAQ
No. Amazon says the seller's guidance is used alongside its standard grading process.
Amazon supports specific ASINs, all ASINs, or bulk configuration by CSV. Starting with a pilot is Bluebug advice, not an Amazon requirement.
Amazon applies its default grading criteria.
Amazon says only one rule can exist per category per ASIN; a new one replaces the current rule.
No guarantee is stated. Sellers should measure observed outcomes.
Conclusion
Customized grading should be governed as an operational rule set: use observable evidence, protect version history, pilot narrowly, and audit results without assuming seller guidance controls every outcome.
