Amazon Q4 2026 Deadlines: Inventory, Deals, and Peak Fees
Your Black Friday inventory has to be inside Amazon by October 14, 21 or 28, depending on how you ship. Here's every Q4 2026 date that's still live, the ones you already missed, and the backward plan that gets units on the shelf in time.
It's October 3. If your Black Friday stock is still sitting at your 3PL, you have about two weeks, and most of that is already spoken for by trucks.
Here's the short answer on the Amazon Q4 2026 deadlines. Amazon's holiday 2026 announcement says Black Friday Week and Cyber Monday inventory must arrive by October 14 if you ship through Amazon Warehousing and Distribution (AWD), October 21 for FBA with minimal shipment splits, and October 28 for FBA with Amazon-optimized shipment splits. Black Friday deals can be submitted until October 20. Holiday peak fulfillment fees start October 15 and run to January 14, 2027.
Those are arrival dates. Not ship dates. So the plan runs backward from them, and for a lot of sellers the real deadline is this week.
Which Amazon Q4 2026 deadlines have already passed?
I'll start with the bad news, because I'd rather you hear it from me than find it in Seller Central on October 22.
Prime Big Deal Days runs October 6 and 7, 2026, starting 12:01 a.m. PDT, in 22 countries. The deal window for it closed September 8. The inventory arrival dates were September 2 (AWD), September 9 (FBA minimal splits) and September 16 (FBA Amazon-optimized splits). If you missed those, the October event is a pricing and ads play on the stock you already have inside Amazon. That's it.
The early-submission discount for Black Friday deals ($50 off the upfront fee) ended September 5. And the Q4 storage rate kicked in on October 1.
Here's the whole calendar in one place, with where each date stands today.

Black Friday falls on November 27, 2026 and Cyber Monday on November 30. On the Amazon pages I opened this week, I didn't find the exact start date of Amazon's 2026 Black Friday Week event. So don't plan around a rumored date. Plan around the arrival cutoff, which is the date Amazon actually published.
The deadline on Amazon's page is the day your boxes need to be inside the building. Your deadline is the day the truck leaves.
How do you work backward from the Black Friday inventory deadline?
Here's the method I'd use if I were still running my own page-one Amazon products. Start at the arrival date and subtract.
- Pick your cutoff: October 14, 21 or 28, based on how you ship.
- Subtract a buffer of 5 to 7 days for dock queues and check-in.
- Subtract your real freight transit time, from your own last three shipments.
- Subtract prep, labeling and carrier pickup at your 3PL.
- The date you land on is your ship-by date. Book it today.
Run the math on a seller like this, a hypothetical. FBA with minimal splits, so the cutoff is October 21. A 6-day buffer puts the target arrival at October 15. Ground freight from the 3PL has averaged 7 days, so the truck leaves October 8. Prep takes 3 days, so the purchase order to the 3PL goes out October 5.
That's two days from today.
Why the buffer? Because the cutoff is when Amazon expects to receive, and receiving in late October is a queue. As one 2026 deadline guide puts it, a shipment that arrives on the deadline "can sit in a yard or a dock queue" and check in days later. Amazon won't reject late stock. It just stops promising your units will be sellable when Black Friday traffic shows up.
How much inventory should you send for Black Friday Week?
Enough to cover the spike. Not so much that it sits in a $2.40 cubic foot all December.
Here's a hypothetical ASIN that sells 40 units a day in a normal week. Assume Black Friday Week through Cyber Monday (call it the 11 days from November 20 to November 30) runs at 2.5x, and the first 20 days of December run at 1.5x. Those multipliers are assumptions. Use your own from last Q4.
| Window | Days | Units per day | Units |
|---|---|---|---|
| November 1 to 19 | 19 | 40 | 760 |
| November 20 to 30 | 11 | 100 | 1,100 |
| December 1 to 20 | 20 | 60 | 1,200 |
| Total need | 50 | 3,060 |
If 900 units are already inside Amazon, you send 2,160. Recheck that number against your restock limits before you build the shipment, because a plan Amazon won't accept is a plan you don't have.
Now the storage side. Say each unit takes 0.1 cubic feet. 2,160 units is 216 cubic feet. At the January to September standard-size rate of $0.78, that's $168.48 a month. At the October to December rate of $2.40, it's $518.40. Same boxes. Three times the rent.
216 cubic feet x the 2026 standard-size monthly rates reported by AMZ Prep: $0.78 January to September, $2.40 October to December.
Q4 punishes both mistakes. Send too little and you're out of stock on Cyber Monday. Send too much and you pay peak rent on units that sell in February.
If you're not sure which of your ASINs deserve the space, finding slow-moving inventory before your Q4 buy is the first cut I'd make.
What do Q4 peak fees and deal fees add to each unit?
Two separate bills, and sellers usually only budget for one.
The first is the peak fulfillment fee. From October 15, Amazon adds an average of $0.32 per unit, and the 3.5% fuel and logistics surcharge applies on top of it. On a hypothetical item with a $5.08 base fee, that's $5.08 plus $0.32, which is $5.40, times 1.035, which is $5.59. I broke down the full stack, and the repricing math to hold your margin, in the Amazon FBA fee changes for 2026.
The second is the deal fee. Amazon's holiday 2026 announcement puts it at $100 upfront per promotion plus 1.5% of promotional sales, capped at $5,000. A deal that moves $20,000 costs $100 plus $300, which is $400, before you count the discount you gave the buyer.
Here's the thing. The deal fee is small. The discount is big. If you're about to submit before the October 20 close, run the margin at the deal price first. How deep to discount for Black Friday walks through what 15, 25 and 40 percent off actually leave you.
What if you already missed the cutoff?
Then you stop fighting the calendar and start protecting what's left. Three moves.
- Ship anyway, priced for December. Late units still sell in the second half of the season. Don't spend Black Friday ad budget on an ASIN that may not be checked in.
- Throttle before you stock out. If your current stock covers fewer days than your arrival date, raise the price a little or trim ad bids so you don't hit zero during the busiest week of the year. A stockout costs you more than a few slower days.
- Push your best traffic somewhere you control. Your own store has no arrival cutoff, no peak fee and no deal fee.
That third one is where I always end up.
Why does every Q4 deadline belong to someone else?
Look at that table again. Every single date on it was set by Amazon. The arrival cutoffs. The deal window. The fee start. The storage rate. You're a tenant planning your biggest month around the landlord's calendar.
I'm not telling you to leave Amazon. I'm telling you to stop letting it be the only shelf.
Three client products on our results page ran on Amazon first, then on their own Shopify store with a rebuilt product page. Real client numbers, not typical results, and not a promise of what your store will do. Smart Animal made $17.58 net profit per sale on Amazon at $49.95. On Shopify, with a 3% platform fee instead of 15% and a $210.86 average order value, it made $134.28 net profit per sale, after paying for ads and inventory.
Revenue per visitor is conversion rate times average order value. Run the math on a store like this, a hypothetical: 10,000 visitors in November, a 1.5% conversion rate and a $60 average order value. That's $0.90 per visitor, or $9,000. Lift the page to a 2.5% conversion rate and a $96 average order value and the same 10,000 visitors are worth $2.40 each, or $24,000. No arrival cutoff. No peak fee.

What to do next
One move, today. Open your three best-selling ASINs, find your cutoff (October 14, 21 or 28), subtract a 6-day buffer, your real freight time and your prep time, and write the ship-by date on a sticky note. If that date is before October 10, book the pickup before you close this tab.

P.S. Amazon's calendar has an arrival cutoff. Your own store doesn't. Hit October 21, then build the shelf nobody can close on you.
Frequently asked questions
What is the Amazon inventory deadline for Black Friday 2026?
Amazon's holiday 2026 announcement lists three arrival dates for Black Friday Week and Cyber Monday: October 14 for Amazon Warehousing and Distribution shipments, October 21 for FBA shipments using minimal shipment splits, and October 28 for FBA shipments using Amazon-optimized shipment splits. These are arrival dates, so work backward from them using your own freight and prep time.
When are Prime Big Deal Days 2026?
October 6 and 7, 2026, starting at 12:01 a.m. PDT, in 22 countries including the US, Canada and the UK. The deal submission window closed September 8 and the FBA inventory arrival dates were in September, so on October 3 the only move left for this event is pricing and ads on the stock you already have inside Amazon.
What is the deadline to submit Black Friday deals on Amazon in 2026?
The Black Friday Week and Cyber Monday deal submission window runs July 8 to October 20, 2026. The $50 early-submission discount on the $100 upfront fee ended September 5, so a deal submitted now costs $100 plus 1.5% of promotional sales, capped at $5,000.
When do Amazon holiday peak fees start in 2026?
Holiday peak fulfillment fees run from October 15, 2026 to January 14, 2027. Amazon says they average $0.32 per unit over standard rates, and its 3.5% fuel and logistics surcharge applies on top of them.
What happens if my inventory arrives at Amazon after the Q4 cutoff?
Amazon doesn't reject it, but it stops promising the units will be checked in and sellable in time for Black Friday Week. Late shipments land in the busiest receiving weeks of the year, so plan to arrive days before the cutoff, never on it.
