Amazon Inventory Update: Restock Limits for FBA Products Replaces ASIN-Level Quantity Limits

FBA sellers welcomed the ASIN-level quantity limits as part of the Amazon inventory update with some push-back. Following the criticism of some FBA sellers, Amazon has introduced a more flexible system, which took effect on April 22, 2021. 

Last July 2020, Amazon announced that they would limit the quantity of FBA products to be accepted in the fulfillment centers. Amazon opined that this ASIN quantity limit would prevent FBA products with high inventory levels but low customer demand from being sent to the FBA warehouse. 

However, the concerns raised by FBA sellers since the implementation of ASIN-level quantity limits came to the attention of Amazon. This resulted in the introduction of restock limits by storage type instead of continuing the ASIN quantity limits.

In Amazon’s own words, the eCommerce-giant stated that “we’ve heard your feedback, and are continuously improving our policies and programs to better receive and store your products.”

How ASIN Level Quantity Limits Impacted Sellers  

The goal of the update back in 2020 regarding ASIN-level quantity limits on FBA products was to maximize the selection for customers during peak season. In theory, this change seemed beneficial; however, its application was a bit troublesome for Amazon FBA sellers. The ASIN-level quantity limits changed the way some FBA sellers conducted their business. FBA sellers who usually send 500 to 1000 units of product from their suppliers directly to the Amazon warehouses were forced to decrease their inventory of new items up to 200 units only.

Consequently, the quantity limit imposed by Amazon forced some FBA sellers to utilize 3PL warehouses to house items that exceeded the ASIN quantity limit.

Impact of the New Amazon Inventory Update

Unlike the previously introduced Amazon inventory update, the new update does not rely on the ASIN-level limit.  Instead, the inventory update is based on restock limits that are calculated by storage type and past & forecasted sales. Thus, enabling sellers to dispense these limits over ASINs.

To help sellers identify the storage type, Amazon listed down four main storage type categories that include:

  • Standard-size includes items not exceeding 18” x 14” x 8”; should weigh 20 lbs or less.
  • Oversize includes items exceeding weight and/or dimensions listed for the standard size.
  • Apparel includes wearable clothing and accessory items
  • Footwear includes shoes, boots, slippers, etc.

If you think of circumventing the restock limits by changing the storage type of a product, Amazon has it covered already. Amazon stipulates the storage type to which a product will belong is gleaned from the characteristics of the inventory item. To understand storage type categories for your products, check FBA Inventory Age
