Inventory commingling has been a quiet source of counterfeit and quality risk for brand owners on Amazon. Amazon ending commingling in March 2026 closes that gap.
What Commingling Actually Was
Under commingled inventory, Amazon pooled units from multiple sellers sharing the same barcode into shared bins. A counterfeit or damaged unit from another seller could ship under your listing.
What Changes in March 2026
Inventory will be tracked at a more granular seller and shipment level, closer to how FNSKU labeling already works, reducing counterfeit-related complaints.
