Long Term Storage Fee Changes Coming April 15th, 2023

If you haven't heard already, Amazon is changing the way they calculate and charge you for long term storage. They are switching to a tiered structure based on how long the items have been in storage at a fulfillment center. 

They have also changed the name to Aged Inventory Surcharge. 

From their help files, they say:

"Effective April 15, 2023, we will increase the granularity and magnitude for the aged inventory surcharge (previously known as the long-term storage fee) on inventory stored between 271 to 365 days. Additionally, we will introduce new tiers to begin the aged inventory surcharge on inventory aged 181 to 270 days for all products except items listed under clothing, shoes, bags, jewelry, and watches in the US. We will continue to charge an aged inventory surcharge for units that we store for more than 365 days.

Aged inventory surcharges are assessed using an inventory snapshot on the 15th day of each month and is in addition to the monthly inventory storage fee."

So they are adding a tier for products 181 to 270 days in storage where they will also apply an added fee on top of the regular Aged Inventory Surcharge (aka Long Term Storage Fee).

This charge will be applied at some point between the 18th and the 22nd of the month, so about a week after they assess the fee in your account. 

Amazon does have a tool in Seller Central called the FBA Inventory Tool that you can use to determine which ASINs are going to be affected by these surcharges.
