2026 has been the busiest year for FBA rule changes in a while. Three of them cost you money, and one of them changed what "prep" even means. This page collects every US FBA update announced for 2026, with the dates, the numbers, and what each one actually does to your unit economics.
The Short Version
| Change | Effective | Impact per unit |
|---|---|---|
| FBA prep & labeling services ended | 1 Jan 2026 | You now pay a third party, or do it yourself |
| Annual FBA fee update | 15 Jan 2026 | +$0.08 average |
| Fuel & logistics surcharge (3.5%) | 17 Apr 2026 | ≈ +$0.17 average |
| Same surcharge on MCF & Buy with Prime | 2 May 2026 | ≈ +$0.17 average |
Roughly $0.25 per unit in new fulfilment cost, plus a prep step you now have to buy or perform. On 10,000 units a year that is about $2,500 before prep.
1 · Amazon Stopped Prepping Your Inventory
This is the biggest change and the one sellers underestimate. As of 1 January 2026, Amazon no longer offers prep and item labeling services in the US marketplace. Every unit has to arrive at the fulfillment centre already bagged, labeled, wrapped and compliant.
Two consequences follow, and the second one is the expensive one:
- Unprepped shipments can be rejected or delayed at check-in. That is the visible cost.
- Unprepped shipments are no longer eligible for reimbursement if units are lost or damaged. That is the invisible one — you only find out when you file a claim and it is denied.
The policy applies to shipments sent directly to FBA and to inventory moving through Amazon Warehousing and Distribution (AWD) and Amazon Global Logistics (AGL).
If you were relying on Amazon to catch a missing poly bag or apply an FNSKU, that safety net is gone. Our poly bag guide and bubble wrap guide cover the two requirements most often missed.
2 · The Annual Fee Update — 15 January 2026
Amazon's yearly fee letter, published by Dharmesh Mehta (VP, Worldwide Selling Partner Services), set out the 2026 rates. The headline numbers, in Amazon's own words:
"In 2026, FBA fees will increase by an average of $0.08 per unit sold, or less than 0.5% of an average item's selling price."
Context worth keeping in mind: there was no increase at all in 2025, and Amazon points out the rise is below the 3.9%–5.9% annual increases announced by major US carriers over the same period. There are also no new fee types in 2026 — the changes are to existing rates and tiers, not new line items.
What "average" hides is that the structure got more granular. Amazon's stated aim is lower fees where its costs are lower and higher fees where it does more work. In practice that means your specific products may move more than $0.08 in either direction, and the only way to know is to check yours.
Amazon updated three tools with 2026 rates: the Revenue Calculator, the Fee and Economics Preview report, and a Profit Analytics dashboard that shows the impact per product. Sellers also got at least 90 days' notice before increases took effect.
3 · The 3.5% Fuel and Logistics Surcharge — 17 April 2026
This one arrived separately from the annual update and caught a lot of sellers out. From 17 April 2026, a 3.5% fuel and logistics surcharge applies to US and Canadian FBA fees. From 2 May 2026 it extends to Multi-Channel Fulfillment and Buy with Prime.
Two details matter:
- It is calculated on your fulfilment fees, not on the sale price. A 3.5% surcharge on a $5 fulfilment fee is about 18 cents — not 3.5% of your revenue. Across US FBA it averages roughly $0.17 per unit.
- Amazon describes it as temporary but has not published a removal date. Sellers who lived through the 2022 fuel and inflation surcharge will have a view on how temporary that tends to be. Plan your 2027 margins as though it stays.
What This Means for Your Margin
Stack the changes and a typical standard-size unit picks up roughly $0.25 in fulfilment cost, plus prep. Prep is the variable you control: doing it yourself costs labour and materials, outsourcing costs a per-unit fee.
Three levers actually move the number:
- Packaging size. Fees are driven by size tier. Shaving a fraction of an inch to drop a tier can be worth more than every other optimisation combined — and it is a one-off change per SKU.
- Inventory age. Aged inventory surcharges are separate from all of the above and are entirely avoidable with honest forecasting. Slow stock is the most expensive stock in FBA.
- Prep cost per unit. At low volume, doing it yourself is often cheaper. Somewhere between 500 and 1,000 units a month that flips, because your own time stops being free.
Where a Delaware Prep Centre Fits
Since Amazon stopped prepping, every US seller has to solve prep somewhere. Sending inventory through a prep centre first adds a step, but it changes three things:
- Units arrive at Amazon compliant, so the reimbursement eligibility problem disappears.
- Prep is a known per-unit cost rather than an unpredictable claim on your week.
- If the prep centre is in a state with no sales tax — Delaware, for instance — inventory purchases routed through it are made in a 0% state.
We prep from Claymont, Delaware: FBA prep from $0.69–$2.00 per unit depending on monthly volume, poly-bagging at $0.75, bubble wrapping at $0.90, with FNSKU labeling and receiving of cartons and parcels included. Turnaround is 48 hours from arrival, and our first-pass FBA acceptance rate is 99.8%.
Whether that maths works for you depends on your volume and what your own hour is worth. The pricing calculator on our homepage will give you a figure in about ten seconds.
Frequently Asked Questions
Did Amazon really stop all FBA prep services?
Yes — prep and item labeling services ended in the US marketplace on 1 January 2026. Units must arrive fully prepped.
How much did FBA fees go up in 2026?
By an average of $0.08 per unit sold, effective 15 January 2026 — less than 0.5% of an average item's selling price, according to Amazon. There were no increases in 2025 and no new fee types in 2026.
What is the 3.5% fuel and logistics surcharge?
A surcharge applied to FBA fulfilment fees from 17 April 2026 in the US and Canada, and from 2 May 2026 on Multi-Channel Fulfillment and Buy with Prime. It is calculated on fulfilment fees, not on the sale price, and averages about $0.17 per unit for US FBA.
Is the fuel surcharge permanent?
Amazon describes it as temporary but has not published a removal date. It is safer to build it into your margins than to assume it disappears.
What happens if my shipment arrives unprepped?
It can be rejected or delayed at check-in, and it is not eligible for Amazon reimbursement if units are lost or damaged.
