Pros and Cons of Amazon Commingling FBA Inventory of Third-Party Sellers

​Amazon's Fulfillment by Amazon (FBA) program allows third-party sellers to store their products in Amazon's warehouses and have them shipped directly to customers through Amazon's platform. While FBA can provide a number of benefits to sellers, such as access to Amazon's vast customer base and logistical infrastructure, there is one aspect of the program that has raised concerns among some sellers: commingling inventory.
Commingling inventory refers to the practice of mixing identical products from different sellers in Amazon's warehouses. For example, if two different sellers are selling the same brand of headphones, Amazon may store both sellers' inventory together in the same bin. When an order is placed for that product, Amazon will choose which seller's product to fulfill the order from based on a variety of factors, such as proximity to the customer and inventory levels.

Advantages of Commingling FBA Inventory

The advantages of commingling inventory to sellers are lower shipping fees and, with inventory commingling it is quicker and easier to label and send in products to Amazon FBA fulfillment centers.

Disadvantages of Commingling FBA Inventory

​Here's how it works: let's say that Seller A sends in a shipment of headphones to Amazon's warehouse. Seller A's headphones are genuine and in good condition. However, Seller B, who is also selling the same brand of headphones, sends in a shipment of counterfeit or defective headphones. Because Amazon is commingling inventory, there is a chance that Seller A's headphones could get mixed up with Seller B's defective or counterfeit headphones. If a customer receives one of Seller B's defective headphones, they may leave a negative review or file a complaint with Amazon, which could result in Seller A's account being suspended or even terminated.
The problem with commingling inventory is that it makes it difficult for sellers to prove that they are not responsible for any defects or inauthenticity in a product that a customer receives. Even if Seller A can prove that their headphones were genuine and in good condition, Amazon may still hold them responsible for any defects or inauthenticity if the product was fulfilled from a bin containing both Seller A and Seller B's inventory.
This is particularly problematic for sellers of branded products, as they may be subject to legal action by the brand owner if their products are found to be counterfeit or inauthentic. If a seller's account is suspended or terminated due to false accusations of selling counterfeit or defective products, it can have a devastating impact on their business.

Sellers Should Opt Out of Commingling

​To avoid these issues, some sellers choose to opt out of commingling inventory and instead have their products fulfilled only from their own inventory. However, this can lead to longer shipping times and higher fees, which can put them at a competitive disadvantage.

Key Takeaways

n summary, Amazon's commingling inventory can have serious implications for FBA sellers who are wrongfully accused of selling defective or inauthentic products. While the practice may improve efficiency, it can also make it difficult for sellers to prove their innocence in the event of false accusations. Sellers should be aware of these risks and take steps to protect themselves, such as opting out of commingling inventory or closely monitoring their inventory and customer feedback.  If you have issues of Amazon accusing you of inauthentic or defective products, do not hesitate to call, email or chat with us for a free consultation on how to resolve the issue.
