Amazon just dropped a massive update on its fee structure for the US and Canadian markets. If you’re a seller, your margins are about to feel the squeeze. Most people focus on the headline numbers. They look at a few cents here and there and think it's business as usual. It isn't. This shift signals a fundamental change in how Amazon wants you to manage your inventory and your logistics.
The new Amazon fees aren't just a tax on doing business. They're a clear message. Amazon is tired of being your long-term storage unit. They want a high-velocity machine. If you’ve got products sitting in a warehouse for months, you’re the target of these changes.
Why Your Low Inventory Levels are Actually Costing You
One of the most aggressive changes involves the Low-Inventory Level Fee. This one caught a lot of people off guard. Essentially, if you don't keep enough stock relative to your sales, Amazon charges you more. It sounds counterintuitive. Why would they penalize you for having less stuff in their way?
The reality is about efficiency. Amazon’s regionalization strategy depends on having your products spread across their entire network. When your inventory dips too low, they can't distribute your items close to every customer. This forces them to ship items across the country, which kills their promise of lightning-fast delivery and jacks up their internal costs.
You’ll see this fee hit if your inventory level relative to historical sales falls below a specific threshold—usually 28 days of supply. It’s a tightrope walk. You have to stock enough to avoid this penalty but not so much that you trigger the revamped storage fees.
The Logistics Shakeup for US and Canadian Sellers
The inbound placement fee is another heavy hitter. Amazon used to let you send everything to one or two hubs, and they’d handle the rest. Now, they want you to do the heavy lifting of splitting shipments. If you want to keep things simple and ship to a single location, you’re going to pay for the privilege.
For sellers in Canada and the US, this means rethinking your entire supply chain. You have two real choices here. You can pay the "Inbound Placement Service" fee and let Amazon distribute the goods, or you can opt for the "Amazon-Optimized" shipment splits. The latter requires you to send your inventory to four or more locations simultaneously. It’s a logistical headache, but it keeps your per-unit costs down.
Breaking Down the New Fulfillment Rates
Shipping costs are going up. That’s the simple truth. But the way they’re going up is nuanced. Amazon has introduced more granular weight tiers. This is actually a win for some. If you sell very light items, you might see a slight decrease or a freeze in rates. However, for the majority of standard-sized products, expect a steady climb.
In the US, the average increase for fulfillment through FBA (Fulfillment by Amazon) is roughly $0.15 per unit. It doesn't sound like much until you move 10,000 units a month. That’s $1,500 straight out of your pocket every single month. In Canada, the adjustments are similar but adjusted for the CAD and local shipping realities.
The Hidden Cost of Returns
Amazon is also getting stricter with high return rates. They’ve introduced a "Returns Processing Fee" for products with the highest return rates in their category. They’re tired of subsidizing poor quality or misleading listings.
If your return rate is significantly higher than your peers, you’re going to pay a penalty on every single returned item. This excludes apparel and shoes, which already have their own specific return fee structures. This move forces you to be more honest in your marketing. Don't overpromise. If the product isn't what the pictures show, the fees will eventually eat your business alive.
Adapting Your Pricing Strategy Before the Hit
You can't just swallow these costs. You have to be proactive. First, audit your entire catalog. If you have SKUs with slim margins that are now subject to the low-inventory fee, it might be time to cut them loose.
Focus on your "Hero" products. These are the ones with high turnover and solid margins. Optimize their packaging to drop into a lower weight tier if possible. Even a fraction of an inch or an ounce can move you into a cheaper category.

Stop Using Amazon as a Storage Locker
The storage utilization surcharge is the final nail in the coffin for slow-moving inventory. If you have more than 26 weeks of supply sitting in FBA warehouses, your monthly storage fees will skyrocket. This is on top of the aged inventory surcharges.
Basically, if it hasn't sold in six months, it shouldn't be there. Period.
Use liquidations. Run aggressive "Buy One Get One" promos. Do whatever you need to do to clear that space. Every square foot of shelf space you occupy with dead stock is a liability that Amazon is now charging you premium rates for.
Strategic Moves for the Rest of the Year
Start by diversifying your fulfillment. While FBA is convenient, look at Third-Party Logistics (3PL) providers for your overstock. Keep your FBA levels lean—just enough to satisfy the low-inventory threshold—and drip-feed inventory from a cheaper 3PL warehouse.
Check your "Inbound Placement" settings in Seller Central right now. Most accounts default to the most expensive option. Changing your workflow to accommodate split shipments is painful for your warehouse team, but the savings are mandatory for survival in this high-fee environment.
You need to become a data-driven operator. The days of "set it and forget it" on Amazon are dead. Monitor your Inventory Performance Index (IPI) score like your life depends on it. Because in 2026, your profit margin certainly does. Tighten your shipping windows and demand better lead times from your suppliers. Efficiency is the only way to win this game.
