Amazon’s New Commingling Policy Explained (2026 Update)
Amazon is ending commingled inventory in FBA by 2026. This means every seller must now label their own inventory with unique FNSKU barcodes before sending products to Amazon fulfillment centers. No more shared inventory pools; each merchant’s stock will be isolated, giving brands more control and protecting against counterfeit and unauthorized sellers.
This major change affects prepping, labeling workflows, and how sellers manage inventory with 3PLs and prep centers. If you’re an Amazon FBA seller or brand, this update is crucial for your compliance and operational strategy.
Watch the full explainer from AMZ Prep to understand what you need to do to stay compliant and simplify your fulfillment process.
