Amazon 2026 FBA Fee Structure Adjustment: A Deep Dive into Its Impact on Storage, Fulfillment, and Seller Profitability

Starting January, 2026, Amazon US officially rolls out a new round of FBA fee changes. Unlike the flat-rate increases we’ve seen in previous years, this adjustment is more structural. While fulfillment fees for standard-size items are going up, fees for large and bulky items are actually coming down. At the same time, aged inventory fees are rising sharply, and inbound placement fees are also increasing.

What Amazon is really doing here is using pricing to push sellers toward better inventory management and more efficient supply chains. For cross-border sellers, understanding each fee change—and adjusting your storage and fulfillment strategies accordingly—will be key to protecting your profit margins in 2026.

1. Summary of Key 2026 FBA Fee Changes

This round of changes covers fulfillment fees, storage fees, inbound fees, and inventory management fees. The table below outlines the most important adjustments for most sellers:

Other related changes include:

• Multi-Channel Fulfillment (MCF) fees: up $0.30/unit on average

• Prime fulfillment fees: up $0.24/unit on average

• Coupon fee cap: $2,000 per coupon (effective Nov 5, 2025)

2. A Closer Look at Storage Fee Changes

Aged Inventory Fees Have Doubled – Amazon Wants Faster Turnover

Under the new rules, the aged inventory fee for items stored 12–15 months jumps from $0.15 to $0.30 per unit per month. For items stored longer than 15 months, the fee is the higher of $0.35/unit or $7.90/cubic foot.

To put that in perspective: if you have a standard-size item sitting in an FBA warehouse for over a year, just the aged inventory fee alone could cost you more than $3.60 per unit per year. For sellers with slow-moving inventory or a “spray-and-pray” strategy, this fee will eat directly into whatever margin is left.

At the same time, Amazon has lowered removal and disposal fees for aged inventory (for standard-size items under 0.5 lb, down $0.20 per unit). The message is pretty clear: Amazon wants you to clean out your old stock, not let it sit there forever.

Monthly Storage Fees and Peak Surcharges Remain High

Basic monthly storage fees haven’t changed, but during the 2025 peak season (Oct 15 – Jan 14), the peak fulfillment surcharge for standard-size items hit as high as $0.55/unit, and peak storage fees were about three times the off‑peak rate. And these peak costs line up directly with the new 2026 rates, so the pressure doesn’t let up.

AWD Storage Fees Are Going Up in Western Regions

If you use Amazon Warehousing & Distribution (AWD), storage fees in the western region are increasing to $0.57 per cubic foot per month. That’s another incremental cost for sellers relying heavily on Amazon’s supply chain services.

3. A Closer Look at Fulfillment Fee Changes

Standard-Size Fulfillment: Higher Prices = Higher Increases

One of the most noticeable things about this adjustment is that the increase for standard-size items is tied directly to the selling price.

For products under $10, Amazon is essentially offering a “discount” on fulfillment costs—about $0.86/unit less than what they’d charge for higher-priced items. This seems like a deliberate move to keep low‑priced products competitive on the platform.

But if you sell items over $50, you’re taking the biggest hit. Sure, higher-priced products usually have more margin to absorb cost increases, but the pressure to hold your pricing line is real.

Large and Bulky Items: Fees Are Going Down

In sharp contrast to standard-size items, fulfillment fees for large and bulky items are actually dropping:

• Small large items: down about $2.06/unit on average

• Extra-large items: down about $2.08/unit on average

Amazon has also split the old “large bulky” category into “small large” and “large large,” making the fee structure more granular. This sends a clear signal: Amazon wants more furniture, appliance, and other bulky goods sellers to join FBA, balancing out the network load and diversifying the product mix.

But there’s a catch. If your large-item products aren’t enrolled in SIPP (Ships in Product Packaging), you’ll be hit with an extra packaging fee of about $2.07/unit on average. So to actually enjoy the lower fulfillment rates, you’ll need to get your packaging right.

Prep and Labeling Service Is Gone – Responsibility Has Shifted

Starting January 1, 2026, Amazon US FBA warehouses will no longer offer labeling or prep services. That means:

• You’re fully responsible for making sure your shipments meet FBA standards before they arrive.

• Every unit must have a valid FNSKU barcode.

• Commingled inventory (sticker‑less mixing) is completely gone.

This shifts the cost and responsibility of prep and labeling entirely to sellers or third‑party logistics providers. If you don’t have the in‑house setup to handle it, you’ll need to find a reliable logistics partner to do it for you.

4. Inbound and Inventory Management Fee Changes

Inbound Placement Fee: Single‑Point Shipments Cost More

For standard-size items choosing “single‑point inbound,” the inbound placement fee is going up by about $0.05/unit on average. That doesn’t sound like much per unit, but if you’re shipping in bulk, it adds up fast. Amazon has also introduced more weight brackets for large standard items (3–20 lbs), making the fees more precise.

Inbound Defect Fee: Simpler, but Stricter

Before, missing, late, or misrouted shipments could trigger both an inbound placement service fee and an inbound defect fee. Now it’s been simplified into a single inbound defect fee of $0.60/unit. The good news is the fee structure is simpler. The bad news is the compliance bar hasn’t lowered—any mistake at inbound will still cost you.

Low‑Inventory Fee: More Granular Tracking

The low‑inventory fee now applies at the FNSKU level instead of the parent ASIN level. This means:

• Different variations under the same parent ASIN are tracked separately.

• Large items are now included in the fee.

• The fee only triggers when historical days of supply drop below 28 days for a specific FNSKU.

This change means you need to manage inventory at the SKU level, not just the product family level. One variant running low could trigger a fee even if the rest of the family is fully stocked. Slow‑sellers may avoid the fee, but they risk slower delivery promises or limited regional availability.

5. How These Fee Changes Affect Seller Profits

Cost Impact by Seller Type

A Quick Cost Example

Take a seller moving 1,500 standard-size units per month. If the average fulfillment fee goes up by $0.25/unit, that’s an extra $4,500 per year (around RMB 32,000). Add in inbound placement fees, possible aged inventory fees, and other small charges, and total cost could easily rise by 5–8%.

For large-item sellers, the math looks different. One small large item drops by $2.06/unit. At 500 units per month, that’s about $12,360 saved per year. But again, to get that saving, your product needs to meet SIPP packaging standards. If not, the extra packaging fee could wipe out most of the gain.

6. What Sellers Can Do: Moving from Reactive to Proactive

Start with SKU‑Level Profit Analysis

Use Amazon’s Profitability Dashboard and the FBA Revenue Calculator to recalculate net profit for every active ASIN. Pay special attention to products near size or weight thresholds—a small packaging tweak could move you into a lower fee bracket.

Clean Up Your Inventory, Especially Aged Stock

With aged inventory fees doubled, don’t wait. Any stock over six months old should be reviewed now. Run promotions, use off‑site channels, or even dispose of it if necessary. Also, with the new FNSKU-level tracking, keep enough stock of your best‑sellers to avoid low‑inventory fees.

Review Your Large‑Item Packaging Strategy

If you sell large items, make sure you’re enrolled in SIPP (Ships in Product Packaging). Otherwise, you’ll pay an extra ~$2.07/unit packaging fee, which will cancel out most of the fulfillment fee drop.

Rethink the Balance Between FBA and Self‑Fulfillment

For bulky, seasonal, or slow‑turnover items, consider a hybrid model: use FBA for your core best‑sellers, and a third‑party overseas warehouse for long‑tail or buffer stock. That way, you still get FBA’s traffic boost without drowning in storage fees.

Find a Reliable Logistics Partner for Prep Work

Since Amazon no longer offers labeling or prep services, you’ll need someone else to handle it. Look for a logistics provider with solid FBA inbound experience—like AMZ SHIPPER. The right partner can make sure your shipments meet Amazon’s requirements every time, saving you from inbound defect fees and rejected shipments.
