Amazon delays in 2026 come from four places: fulfillment center receiving, carrier hand-offs, prep and labeling errors, and customs. For FBA sellers, most delays now start inside Amazon’s own network, not at the port. Customs became a bigger factor after the US ended duty-free de minimis entry.
- Q4 peak is starting. In past peaks, Amazon has told sellers its fulfillment centers focus on receiving in September and October, then on customer orders in November and December. Inbound sent now lands in the tightest receiving window of the year.
- SFP speed metrics now count in full. The Seller Fulfilled Prime grace period on the new delivery-speed metrics ended October 17, 2026.
- US de minimis remains suspended. CBP made the suspension indefinite by regulation on June 24, 2026, so every low-value import needs a formal or informal entry.
Amazon Shipping Problems: What Changed for Sellers in 2026
Across the brands we support, the biggest shift this year isn’t the weather. It’s Amazon’s own rule changes. Four of them change how a delay hits your account.
On-Time Delivery Rate (OTDR) Change: February 28, 2026
Amazon enforces a 90 percent on-time delivery rate on seller-fulfilled listings. The threshold did not change. The enforcement did.
Before, one weak area could take down your whole catalog: a drop below 90 percent deactivated all seller-fulfilled listings. From February 28, 2026, Amazon only deactivates the listings driving the low score. Your other listings stay active.
This is better news for most sellers, but it isn’t a free pass. The listings Amazon pulls are the ones hurting your rate most, and those are often your best sellers. Flagged listings appear in Account Health under Product Policy Compliance, labeled “Order Performance – On time Delivery Rate.”
You can protect tracked orders. Pair shipping settings automation with Amazon Buy Shipping and automated handling time to shield yourself from carrier-caused delays.
Two related changes landed the same month:
- February 8, 2026: all seller-fulfilled returns moved to Amazon Prepaid Return Labels.
- February 16, 2026: the SAFE-T claim window for seller-fulfilled orders dropped from 60 to 30 days.
FBA Inbound Prep Changes: January 1, 2026
As of January 1, 2026, Amazon stopped offering prep and labeling for US inbound shipments. That covers FNSKU labeling, poly-bagging, bubble wrapping, bundling and boxing.
You now prep and label before units reach the fulfillment center. Shipments created before January 1, 2026 could still use the old service.
The change covers inventory sent directly to FBA, plus inventory coming through AWD, Amazon Global Logistics, Amazon SEND and Supply Chain Portal. Shipments created after January 1 that arrive without proper prep aren’t eligible for reimbursement if units are damaged or untraceable. A small labeling miss now carries real cost, so correct FBA prep at the source matters more than ever.
Commingling Phase-Out: March 31, 2026
Commingling ended for inventory shipped on or after March 31, 2026.
- Resellers without a Brand Registry brand representative role must now put Amazon barcodes on every unit, even when the product has a manufacturer barcode.
- Products with no manufacturer barcode need Amazon barcodes from everyone.
FBA Fee Changes: January 15 and April 17, 2026
Amazon raised FBA fees by an average of $0.08 per unit on January 15, 2026, which it puts at less than 0.5 percent of an average item’s price. A 3.5 percent fuel and logistics surcharge on FBA fulfillment fees followed on April 17, in the US and Canada.
Extra safety stock now costs more to hold, so check our FBA fees breakdown before sizing your buffer.
Why Is Amazon Shipping So Slow?
Amazon shipping feels slow in 2026 for three reasons:
- Inbound freight waits longer in fulfillment center receiving, especially before peak.
- Carriers miss delivery windows during volume spikes and bad weather.
- Imports now clear customs through full entries, since duty-free de minimis entry ended.
For shoppers, a slow Prime estimate usually means the item is stocked far away or still in receiving.
How Long Do Amazon Shipping Delays Last?
How long an Amazon delay lasts depends on where it starts. Receiving is the most predictable:
- Small-parcel shipments can take up to six days to move from scheduled delivery to Receiving.
- LTL and FTL freight can take up to 19 days.
| Delay type | What Amazon or CBP says | What to do |
|---|---|---|
| Small-parcel receiving | Up to 4 days to Checked in after scheduled delivery, then up to 2 days to Receiving | Wait out the window before opening a case |
| LTL and FTL receiving | Up to 10 days to Checked in, then up to 9 days to Receiving | Book live unload appointments where possible |
| Peak receiving | Amazon can’t expedite receiving, and holiday timelines can run several weeks | Land inventory before November |
| “Delivered” but not received (shoppers) | Packages can be scanned delivered before they arrive | Wait 48 hours, then contact Amazon or the seller |
| US customs | Since August 29, 2025, every import needs a formal or informal entry | File the entry before freight lands |
What Causes Amazon Shipping Delays?
For years, sellers blamed the ocean. Ports and canals still matter, but most delays we see now start closer to home.
Fulfillment Center Receiving
Amazon allows up to four days for a small-parcel shipment to reach Checked in after its scheduled delivery, and up to ten for LTL and FTL. Receiving starts after that, and Amazon can’t manually speed it up.
Inventory in “Receiving” status is not yet sellable. Amazon has not fully accepted it, so your stock exists but cannot fill orders.
Congestion, labeling errors and missed unload appointments all extend this window. Each one delays the moment your inventory goes live.
Carrier and Dock Scheduling
The carrier you pick affects your receiving speed. Carriers without live unload appointments sit in drop-trailer queues.
A flagged inbound can also surface as a shipment exception that needs separate resolution. Choosing carriers with Amazon dock experience keeps your inbound predictable.
What “A Carrier Delay Has Occurred” Means
“A carrier delay has occurred” is a carrier tracking exception, most often from UPS. It means the package missed its planned delivery and the carrier is arranging a new attempt. It isn’t an Amazon status.
Sellers report seeing it repeat for several days on inbound shipments to busy fulfillment centers. Track the shipment status in Seller Central alongside carrier tracking, since Amazon’s status decides when stock goes live. If the exception sits for days with no movement, it can turn into a shipment exception that needs its own fix.
Upstream Ports and Weather
Upstream causes still exist. Port congestion and winter weather still add time on some lanes.
These are real, but they’re the smaller share for most sellers. If your goods move by ocean, plan timing with a freight forwarding partner, and build the transit buffer into your reorder dates.
Amazon Shipments Delayed at Customs
Customs became a bigger delay source after August 29, 2025. That day, the US suspended duty-free de minimis treatment for every country. Shipments valued at $800 or less now need a formal or informal entry, with duties paid.
The suspension outlasted the Supreme Court’s February 20, 2026 ruling on IEEPA tariffs. CBP made it indefinite by regulation on June 24, 2026. A statute repealing de minimis outright takes effect July 1, 2027.
Every entry needs three things:
- an importer of record
- a tariff classification
- an accurate product description
A gap in any of them can hold freight at the border. A licensed customs broker or freight forwarder files the entry. File before the freight lands, not after. Our import duty calculator helps you budget the duty side.
Amazon Inbound Shipment Delayed? How to Fix It
A stuck inbound shipment usually has a cause you can find. Work through these steps in order:
- Check the status in Send to Amazon. Delivered, Checked in and Receiving mean different things. Checked-in boxes haven’t been opened yet.
- Match it against Amazon’s windows. Small parcel can take up to four days to check in after scheduled delivery, plus two to start receiving. LTL and FTL can take up to ten, plus nine.
- Get proof of delivery. For non-partnered carriers, pull the carrier’s delivery record with date, time and your FBA shipment ID.
- Check labels and contents. Every box needs its own FBA Box ID label. Every unit needs a scannable FNSKU, and contents must match the shipment plan.
- Open a case once the window passes. Include the shipment ID, proof of delivery and box count.
- Cover the gap. Forward stock from a 3PL buffer, or switch top SKUs to seller-fulfilled until receiving clears.

How Amazon Delivery Delays Hit Your Seller Metrics
A late shipment is not one problem. It triggers a chain of account effects, and this is the part sellers underestimate.
IPI Score and Storage Limits
Delays drop your in-stock rate, which is one of the inputs to your Inventory Performance Index. IPI in turn feeds the FBA capacity limits Amazon sets each month. Running short can also trigger Amazon’s low-inventory-level fee.
Tighter limits force hard choices during your best selling weeks. Recovery from an IPI dip can take more than one cycle.
Buy Box and Search Ranking
A few days out of stock can reset hard-won momentum. Competitors capture the Buy Box while you’re out of stock, and each day off the Buy Box is lost revenue you rarely recover.
Out-of-stock products often lose search positions too. Rebuilding rank takes time and ad spend, and each stockout makes the next recovery harder.
On-Time Delivery Rate (OTDR) and Account Health
For seller-fulfilled and SFP orders, late deliveries lower your OTDR. Under the 2026 rules, that can deactivate the affected listings.
SFP carries a higher bar:
- an on-time delivery rate of at least 93.5 percent
- a valid tracking rate of at least 99 percent
- a cancellation rate under 0.5 percent
Amazon raised SFP delivery-speed thresholds on July 6, 2026, and the grace period on those metrics ended October 17. A single bad carrier weekend can move these numbers.
Amazon Late Shipment Rate
Late shipment rate tracks seller-fulfilled orders confirmed as shipped after their expected ship date. Amazon’s target is under 4 percent, and it sits next to OTDR in Account Health. LSR measures how fast you dispatch; OTDR measures whether the carrier delivered on time.
How to Limit Your Exposure to Shipping Delays
You can’t remove every delay, but you can build operations that absorb them. These are the steps that work for the brands we support.
Build a 3PL Buffer
Hold a portion of your inventory at a US third-party fulfillment partner, and forward stock to Amazon when FBA hits a trigger point.
This 3PL buffer absorbs receiving and transit delays, so your in-stock rate holds while competitors wait on inbound. It adds some complexity, but the protection is worth it.
Adjust Reorder Points and Lead Times
Set reorder points around today’s timelines, not pre-2020 ones. Add the receiving window to your math, not just ocean transit.
Around peak, work backward from carrier cut-off dates so inbound lands before the rush. Build the delay buffer into cash flow, so a slow lane doesn’t stall sales.
Diversify Carriers and Inbound Routing
Avoid depending on one port or one carrier, and route through more than one entry point when volume allows.
Pick carriers with live unload appointments and Amazon dock experience, and plan a secondary routing option for each shipment.
Use Amazon’s Protection Tools
Turn on shipping settings automation and automated handling time, and add OTDR Protected labels through Amazon Buy Shipping.
These steps keep carrier-caused delays from counting against you. They take an afternoon to set up and protect your metrics all year.
Amazon Shipping Delays in Canada
Amazon.ca sellers face the same receiving windows, plus Canada-specific risks.
Labour disruption
Canada Post workers struck nationally from November 15 to December 17, 2024. A second national strike began September 25, 2025, then shifted to rotating strikes until November 21. Brands relying on one carrier lost weeks of delivery.
Distance
Canada Post’s Regular Parcel standard between regions is 4 to 10 business days for major centres, and longer for remote areas.
Customs
Freight from the US needs customs clearance into Canada before it reaches an Amazon.ca fulfillment center.
Stocking a Canadian 3PL ahead of demand cuts these risks. For current status, see our Canada Post strike updates and our comparison of delivery companies in Canada.
What to Do Next
Shipping delays are now a fixed input in Amazon planning, not a seasonal event. The sellers who build for them this quarter will protect their rankings through the next disruption.
Start by setting reorder triggers around Amazon’s real receiving windows, not best-case ones. Then add a 3PL buffer for your top SKUs before November.
What Should I Do If My Amazon Order Is Late?
If your Amazon order hasn’t arrived by the expected date, check Your Orders first. Most late orders show a revised delivery date.
If tracking says delivered but nothing arrived, check around your address and with neighbors. Wait 48 hours, since packages can be scanned as delivered before they arrive.
Still missing? For orders sold by a third-party seller, contact the seller. For orders shipped by Amazon, contact Customer Service within 30 days of the expected delivery date.
Frequently Asked Questions
Why are Amazon shipments delayed in 2026?
Most 2026 delays start inside Amazon’s network, at fulfillment center receiving. Carrier misses, prep and labeling errors, and customs entries add more. Customs grew as a cause after duty-free de minimis entry ended in August 2025.
What is going on with Amazon shipping right now?
As of October 2026, Amazon’s network is heading into Q4 peak, when receiving slows. De minimis remains suspended, and the new Seller Fulfilled Prime speed metrics count in full from October 17.
Why is Prime delivery taking longer in 2026?
Your Prime estimate depends on where the item is stocked. If inventory sits far away, is still in receiving, or ships from a seller’s warehouse, the estimate gets longer. Peak volume in November and December stretches it further.
How do shipping delays affect my Amazon account?
Delays lower your in-stock rate, which feeds your IPI and capacity limits. Stockouts can cost you the Buy Box and search ranking. For seller-fulfilled orders, late deliveries cut your OTDR and can deactivate affected listings.
What is the Amazon OTDR requirement in 2026?
Amazon requires a 90 percent on-time delivery rate for seller-fulfilled listings. Since February 28, 2026, only the listings with the most impact on a low score get deactivated, not your whole catalog. Seller Fulfilled Prime requires at least 93.5 percent.
Why does Amazon Business take longer to ship?
Many Amazon Business orders go to offices that only accept deliveries during business hours, so weekend arrivals wait until Monday. Amazon now tracks a business-hour delivery rate for sellers in the Account Health dashboard.
Are Amazon UK deliveries delayed?
Amazon.co.uk follows the same steps as the US. Check Your Orders for a revised date. If a parcel shows delivered but hasn’t arrived, Amazon asks you to wait 48 hours before contacting Customer Service.
Can a 3PL reduce Amazon shipping delays?
Yes. A third-party logistics partner holds buffer inventory close to customers, and you forward stock to Amazon before FBA runs low. That protects your in-stock rate during port, weather or receiving delays without tying up all your capital.

The IPI point is the big one. A stockout can shrink storage limits right before peak, so the delay costs you twice.
Didn’t know mixed domestic and international pallets could trigger a customs review. That’s a carrier problem that looks like an Amazon delay.
The commingling change will catch resellers off guard. Skip the barcodes after March 31 and the stock gets marked defective.
The Feb 28 OTDR change helps, but the listings it suppresses are usually your best sellers anyway.
5–14 days for a prep rejection is brutal. A missed label now means a full return and reship.
I always underestimated ranking drops from stockouts. Thanks to AMZ Prep for highlighting this.
Shipping delays are killing my Q4 momentum. Great to see this guide addressing them head-on.
Diversifying ports + 3PL buffer = smart move. Thanks for laying out the strategy.
