You pull up your Amazon storage fee report and there’s a new line item you weren’t expecting. Inventory that’s been sitting for six months just got hit with a charge that used to only apply after nine. If you’re managing FBA stock that isn’t moving, the aged inventory surcharge now shows up faster than it used to, and a lot of sellers are getting caught off guard by the timing.
As of recent updates to Amazon’s fee schedule, it kicks in at 181 days in storage instead of the 271-day threshold that held for years. That’s roughly three months less runway to sell through slow stock before Amazon starts charging extra on top of your regular monthly storage fee. If you’ve got units approaching the half-year mark, it’s worth understanding exactly how the surcharge is structured and what your options are before it hits.
What changed with the aged inventory surcharge
Historically, Amazon gave sellers roughly nine months before aged inventory started costing extra. Recent fee schedule updates moved that first tier down to 181 days, meaning inventory that’s been sitting in a fulfillment center for just over six months now qualifies. The surcharge then steps up in tiers the longer a unit stays unsold — inventory in the 181-to-270-day range pays the lowest tier, with higher rates applying past 271 days and the steepest charges reserved for anything still sitting after a year.
The rates themselves move often enough, and vary enough by size tier, that you shouldn’t lean on a number from any blog post — check your own account’s storage fee report in Seller Central for the current schedule. What matters for planning is the shape of the change: the clock starts running out sooner than it used to, and inventory that felt “not urgent yet” under the old timeline may already be accruing charges under the new one.
Aged inventory vs. storage utilization surcharges
These two get confused constantly because they can both show up on the same SKU at the same time, but they’re triggered by different things.
- Aged inventory surcharge is about how long a unit has physically been in storage, full stop. It doesn’t matter how fast it’s selling — if it’s been sitting past the threshold, it’s subject to the charge.
- Storage utilization surcharge is about how much inventory you’re holding relative to how fast it sells. If your weeks of supply run above roughly 22 weeks for a given size tier, you can get hit with this surcharge even on inventory that arrived recently, as long as you’re holding far more than your sales velocity justifies.
A slow-moving SKU that’s been in an Amazon warehouse for eight months can rack up both at once — the aged-inventory charge for how long it’s sat, and the utilization charge for having too many units relative to how few are selling. That combination is usually the clearest sign a listing needs a real decision, not another markdown.
Why this catches sellers off guard
Most sellers who track aged inventory built their mental model — and sometimes their spreadsheets — around the old 271-day mark. A SKU that was fine at month five under the previous rules is now three weeks past the new threshold. If you haven’t rebuilt your aging reports around the current cutoff, you can end up with surcharges showing up on units you weren’t watching yet.
It’s also easy to underweight how fast the charges compound once a SKU crosses into the next tier. It stacks on top of your regular monthly storage fee, and if that SKU is also tripping the storage utilization surcharge, you’re paying three separate charges on inventory that isn’t generating any revenue. Six more months of “it’ll probably sell eventually” gets expensive fast.
What to do before your inventory crosses the threshold

Once you know which SKUs are approaching 181 days, you’ve got a handful of real options, roughly in order of how much they typically recover:
Discount and push it through FBA
If the product still has demand at a lower price, an aggressive markdown or a Lightning Deal can move enough volume to clear the SKU before the surcharge tier changes. This works best when the issue is pricing, not demand — if nobody wants the product at any reasonable price, a deeper discount just delays the same problem.
Remove it and sell it yourself
You can file an FBA removal order and get the inventory shipped back to you or a 3PL, then sell it through another channel. This gets you out of Amazon’s storage fees entirely, but removal has its own per-unit cost, and once it lands you’re on the hook for storing, listing, and shipping it yourself — removal order fees are worth pricing out before you commit, since they’re not the end of the cost, just the start.
Liquidate the batch
For inventory that isn’t going to sell through at any price you’re willing to accept on Amazon, liquidating the batch in bulk gets it off your books and turns it into cash instead of a recurring fee. You give up some margin compared to a full-price sale, but you also stop paying storage and surcharges on units that were never going to move fast enough to matter anyway.
Running the math before you decide
The right call depends on how much longer the surcharges would run and what the inventory is actually worth to you at this point. A rough way to think about it: add up what you’d pay in aged-inventory and storage-utilization surcharges over the next few months if the SKU keeps sitting, compare that to what a markdown, a removal, or a bulk sale would net you today, and go with whichever number actually gets money back in your pocket. Sellers who wait for the “someday” sale often end up paying more in stacked storage fees than they would have lost by liquidating three months earlier — a pattern worth keeping in mind when you’re deciding how to raise your recovery rate on a batch you’re ready to move on from.
If you’d rather skip the removal-and-relist cycle entirely, you can get a no-obligation estimate on what your current stock is worth through Recouply’s InstantQuote and have a formal offer the same day.
FAQ: Amazon’s aged inventory surcharge
What is Amazon’s aged inventory surcharge?
It’s an extra charge Amazon applies on top of your regular monthly storage fee once a unit has been sitting in a fulfillment center past a certain age. As of recent fee schedule updates, that threshold starts at 181 days and increases in tiers the longer the inventory sits unsold.
Is the aged inventory surcharge the same as long-term storage fees?
They’re closely related but not identical — “long-term storage fee” is the older, broader term sellers use for any charge tied to how long inventory has been stored, while this is the specific current mechanism Amazon uses to apply that cost in tiers. The storage utilization surcharge is a separate charge based on weeks of supply rather than age.
How do I check which of my inventory is at risk?
Seller Central’s Inventory Age report and Storage Fee report both show how long each SKU has been in storage and flag which units are approaching or past the aged inventory threshold. Checking that report monthly is the easiest way to catch aging stock before the next tier kicks in rather than after.
