Amazon is ending its inventory commingling practice as of March 31, 2026, which allowed the company to store and ship products from different sellers together, even if they had the same SKU. This change aims to reduce the risk of customers receiving counterfeit products from reliable sellers. The practice had been criticized for enabling fraudulent activities and making it difficult for customers to ensure they were buying genuine products. The change will apply to new inventory shipped to Amazon by sellers on or after March 31.
