Quick answer. The Amazon late shipment rate is the share of seller-fulfilled orders you confirm after their expected ship date, and Amazon requires it to stay under 4 percent across 10-day and 30-day windows. A second metric, On-Time Delivery Rate, measures how many tracked units reach the buyer by the delivery date you promised, and on Amazon.com it must stay at 90 percent or higher over a 14-day window. Miss either one and Amazon can suspend your Fulfilled by Merchant privileges or deactivate the affected offers. The fix that holds is operational, with handling times your warehouse can meet, shipment confirmed with valid tracking the day the label is bought, and a daily check on every order near its ship-by date.

What Amazon Means by Late Shipment Rate and On-Time Delivery

The two metrics sound alike and measure different moments in an order’s life. Late Shipment Rate looks at the moment you tell Amazon the order has shipped. On-Time Delivery Rate looks at the moment the package reaches the buyer. A seller can fail one and pass the other, and the cause behind each failure is usually different. Getting this distinction right is the first step in any fix, and it is the first thing a reviewer checks when you appeal.

Late Shipment Rate

Amazon’s Seller Central help page defines Late Shipment Rate (LSR) as the percentage of orders shipped late out of total orders. An order counts as shipped late when there is no shipment confirmation by the expected ship date. The metric applies only to seller-fulfilled orders. Fulfillment by Amazon orders are outside it because Amazon ships them.

The policy is direct. Amazon requires sellers to maintain an LSR below 4 percent to sell in the Amazon store. Above 4 percent, Amazon states it may suspend your Fulfilled by Merchant selling privileges or deactivate seller-fulfilled offers with high rates of late shipments. Amazon also notes that expected ship dates are adjusted for national holidays, so a holiday closure that Amazon recognizes does not count against you on its own.

Notice what the definition measures. It measures confirmation. A package that left your dock on time but was confirmed in Seller Central a day after the expected ship date still counts as late. In our casework this is the single most common surprise for owners. They look at their carrier pickup logs, see that everything moved on time, and cannot understand the red number on Account Health. The timestamps that matter are the confirmation timestamps.

On-Time Delivery Rate

On-Time Delivery Rate (OTDR) measures the percentage of your tracked seller-fulfilled units delivered on or before the seller-promised “Deliver by” date. Amazon’s help page states that, effective September 25, 2024, sellers must maintain a minimum 90 percent OTDR without promise extensions to have seller-fulfilled products listed on Amazon.com. Amazon recommends 95 percent or higher for a good customer experience.

The phrase “without promise extensions” matters. Promise extensions are extra days Amazon may add to the delivery date shown to customers to account for weather, network constraints or a seller’s history of late deliveries. Amazon now measures you against your own promise, calculated from your handling time and transit time settings, before any extension is added. The help page gives an example. With one day of handling and two days of transit, an order received Monday must be delivered by Thursday to count as on time, even if the customer was shown Friday.

OTDR does not apply to FBA offers, because Amazon carries the delivery promise for those orders. It also measures units, and it is averaged across all your tracked shipped units, so one slow SKU can pull down the rate for the whole account.

Why both metrics matter to your account

Amazon ties both metrics to the buyer’s experience. Its LSR page explains that orders confirmed late can lead to increased A-to-z Guarantee claims, negative feedback and buyer contacts. That means a shipping problem rarely stays a shipping problem. Late orders feed the Order Defect Rate, which carries its own 1 percent limit and its own enforcement. Our guide to the Amazon Order Defect Rate above 1 percent explains how those defects stack up. When we review an account with a shipping notice, we check the defect metrics at the same time, because the same backlog usually shows up in both.

How the 10, 14 and 30 Day Windows Work

Each metric uses its own window, and the windows explain why a problem can appear suddenly and then take weeks to clear. Reading them correctly tells you how long your fix will take to show, and it stops you from making changes on the wrong day.

Metric	Window	Target	What it counts
Late Shipment Rate	10 days and 30 days	Under 4%	Orders confirmed after the expected ship date
On-Time Delivery Rate (Amazon.com)	14 days	90% minimum, 95% recommended	Tracked units delivered by the seller-promised “Deliver by” date

The 10-day and 30-day LSR windows

Amazon measures LSR over both a 10-day and a 30-day period. The short window reacts quickly. A two-day warehouse outage can push the 10-day rate well above 4 percent while the 30-day rate barely moves. The long window holds on to the problem. Once those late orders are in the 30-day period, they stay there until they age out, no matter how well you ship in the meantime.

This has two practical consequences. First, a spike in the 10-day window is your early warning, and it is the right moment to act, before the 30-day number catches up. Second, after you fix the cause, the 30-day window will look bad for up to a month. Reviewers know this. What they look for is a clean run of confirmations after the fix date, which is why we always show the order-level data from the day the change went in.

The 14-day OTDR window

OTDR uses a 14-day window built in a specific way. Amazon’s help page explains that it takes shipments with a promised delivery date in the last 21 days and excludes the most recent 7 days, because those packages may still be in transit. In Amazon’s own example, a seller with 130 units promised in the last 21 days, 30 of them in the last 7 days, is measured on the remaining 100. If 90 arrived on time, the rate is 90 percent.

The 7-day lag means the OTDR you see today reflects deliveries promised one to three weeks ago. If you change carriers today, the metric will not start to reflect it for at least a week. Plan your evidence with that delay in mind. Amazon also notes that for the US store the “Deliver by” date is measured in Pacific Time, so a package delivered late in the evening on the East Coast can still count against you on the following day’s clock.

Where to read the numbers

Both metrics live in Account Health. Amazon’s instructions are to open Account Health, select View details in the Shipping performance section, choose the metric and select Download report. The report lists the orders that counted against you. Every diagnosis we run starts with that download, because the order list shows patterns the headline percentage hides, such as one fulfillment location, one shipping method, one day of the week, or one SKU with a handling time set too short.

Common Causes of Late Confirmation and Late Delivery

When we review shipping cases, the cause almost always sits in a setting or a process the seller controls. The reviewer is checking exactly that. The most common mistake in an appeal is blaming the carrier when the timestamps show the order was confirmed late. Here are the causes we see most, grouped by the metric they hit.

Causes of a high Late Shipment Rate

Handling time set below real capacity. The handling time on the listing or shipping template promises a ship date your team cannot meet on busy days. Orders ship on your normal schedule and still count as late.
Confirmation lag. Labels are bought and packages leave, but confirmation is uploaded in a batch the next morning or after a manual review. The package was on time. The confirmation was not.
Integration failures. A shipping platform or order management system stops pushing confirmations to Amazon after an update, a credential change or an API error. Nobody notices until the 10-day rate turns red.
Peak backlogs. A holiday spike, a promotion or a viral listing brings in more orders than the warehouse can pick and pack before the expected ship date.
Weekend and cutoff gaps. Orders placed after the daily cutoff or on days the warehouse does not operate carry ship dates the team cannot meet if the template does not reflect operating days.

Causes of a low On-Time Delivery Rate

Transit time set too short. The shipping template promises two-day transit on a service that takes four days to some regions.
Carrier service mismatch. The cheapest service is used for orders carrying a faster promise.
Late handoff. Packages are confirmed on time but the carrier does not scan them until the next day, which eats into the transit window.
Untracked shipments. OTDR counts tracked units. Shipments without valid tracking create a separate problem under the Valid Tracking Rate, covered in our guide to the Amazon Valid Tracking Rate restriction.

The business models that trigger these metrics

The causes above show up most often in three business models. Each one can run inside Amazon’s targets, and each needs a specific control to do so.

Merchant-fulfilled sellers with short handling times. Many sellers set one-day handling to win the Buy Box or a faster delivery badge, then ship on a two-day rhythm. Orders confirm late even when they ship normally. To run it compliantly, set handling time to what the warehouse achieves on its busiest days, then shorten it only after a month of data shows you can hold it. Amazon offers automated handling time for Professional sellers, which sets handling per SKU from how long each SKU usually takes to reach the carrier.

Dropshippers relying on third-party retailers or suppliers. When a supplier ships for you, your confirmation depends on someone else’s timeline. If the supplier sends tracking late, you confirm late. If the supplier ships slowly, you deliver late. To run it compliantly, put the supplier’s ship time in writing, require tracking to be sent to you by a fixed hour each day, build the supplier’s real time into your handling time, and remove any SKU the supplier cannot ship on schedule.

Small warehouses during peak season. A team that handles normal volume comfortably can fall behind in the week after a holiday sale. To run it compliantly, raise handling time on the templates before the peak, add temporary pick and pack capacity, and use vacation or holiday settings when the warehouse closes. A seller who raises handling time for two weeks loses a little conversion. A seller who misses ship dates for two weeks can lose FBM privileges.

Writing a Plan of Action for Shipping Performance

If your offers are already deactivated, the way back is an appeal from the Account Health page. For LSR, Amazon’s help page says to follow the appeal path by selecting Submit appeal and following the online instructions for reinstatement. For OTDR, Amazon states the request will be reviewed within 72 hours and should cover three things, the issues that led to a low on-time delivery rate, the actions you will take to improve it and the steps you have taken to prevent future issues.

Our method for shipping cases rests on one position, that the shipping metrics are back inside target because the cause was found and changed. The root cause, the corrective steps and the preventive controls each point back to that one claim about your shipping workflow. Reviewers read many of these each day and reward a specific, owned answer. Boilerplate is set aside.

Open with the notice and your position

Name the metric Amazon cited, the window and the rate shown. State your position in one controlled sentence, that the late confirmations traced to a specific setting or process, that setting or process has changed, and current confirmations are on time. Do not argue that the metric is unfair, plead hardship or describe how long you have sold on Amazon. None of that is evidence.

Name the root cause precisely

The root cause names the window, the orders and the exact step that failed. “We had shipping delays” will be rejected. “Between the 3rd and the 12th, 41 orders were confirmed late because our shipping software stopped syncing confirmations after a password change, and confirmations were uploaded manually the following morning” gives the reviewer something they can verify against the order report.

The three causes we see most in approved plans are the handling-time setting, the confirmation lag and carrier pickup. Pick the one the data supports. Do not blame the carrier when your own timestamps show the confirmation was late, because the reviewer can see the confirmation time and will read the explanation as a sign the problem will repeat. Do not blame buyers or Amazon’s tools either.

List corrective actions already taken

Corrective actions are what you have already done, ideally within a day or two of the notice. Be concrete and give numbers.

Cleared the backlog and confirmed every open order with valid tracking.
Reset handling time on the affected templates or SKUs to the capacity the warehouse meets.
Repaired the integration that stopped sending confirmations and verified it against a test batch.
Contacted buyers on late orders and resolved any open claims.

Describe preventive measures with an owner

Preventive measures are the permanent controls tied to the exact failure. Name the control, the person who owns it, when it runs and how often it is audited. For shipping cases those controls are a same-day confirmation rule, a daily ship-by check and carrier standards with an owner. “We will be more careful” fails every time, because it gives the reviewer nothing to verify.

For OTDR on Amazon.com, the reinstatement terms are specific. Amazon states that Professional sellers who ship from the US and China are required to meet the 90 percent requirement by using three tools for their seller-fulfilled orders for the next 180 days, which are Shipping Settings Automation, automated handling time and Amazon Buy Shipping. Individual sellers, and Professional sellers shipping from outside the US or China, must submit an appeal showing how they will improve the rate. If you fall into the first group, your plan should confirm the three tools are active and name the templates and SKUs they cover.

Plan of Action template for shipping metrics

Notice and position. The metric, the window, the rate and one sentence stating the cause has been found and changed.
Root cause. The step that failed (handling-time setting, confirmation lag or carrier pickup), the date range and the number of affected orders.
Corrective actions. Backlog cleared, handling times reset, integration repaired, open orders confirmed with tracking, buyers contacted, each with a date.
Preventive measures. Same-day confirmation rule, daily ship-by check, carrier standards and any Amazon tools enabled, each with an owner and a cadence.
Evidence. The metric notice, the affected order IDs, carrier records and your current metrics.
Request. Reinstatement of FBM privileges or the deactivated offers, with a short statement that nothing in the plan is an admission.

Attach evidence that matches the plan

The evidence for a shipping case is simple and specific, namely the metric notice, the affected order IDs, carrier records and your current metrics. Carrier records include pickup scans that show when packages left. Screenshots of your corrected handling-time settings and shipping templates show the change. Attach only records you can pull from Seller Central or your carrier account today, and cite each order ID or pickup scan in the paragraph it proves.

First time compared with repeat

Amazon’s LSR and OTDR pages do not describe a separate tier for repeat breaches. A second breach is assessed against the same targets, with your earlier Plan of Action on record. In practice that makes the second plan harder. If the first plan promised a daily ship-by check and the rate fell again, the reviewer will ask why that check did not work. For OTDR, Amazon states that on subsequent violations where the rate is still below 90 percent, you appeal by selecting Resolve issues on the “Complete your priority actions” banner at the top of Account Health. If your first appeal on a shipping metric has already been denied, our guide on an Amazon late shipment appeal denied covers how to rebuild it.

Regional differences and the law

The rules above come from Amazon’s US Seller Central pages. Sellers on the UK and EU storefronts work under the sellercentral-europe.amazon.com versions of these pages, and the details differ. The UK late shipment page measures LSR over the same 10-day and 30-day periods and offers some sellers at risk of deactivation a five-question policy quiz in the Account Health banner. The 90 percent OTDR rule described above is written for Amazon.com. Read the help page for the storefront where your offers were deactivated before you write anything.

Behind Amazon’s targets sit the consumer laws of each region. Amazon’s policy decides your appeal, so use the law to frame your process, never to argue with the reviewer. This is general information for sellers. Ask a licensed attorney how these rules apply to your own shipping promises and contracts.

Region	Law	What it means for shipping times
United States	FTC Mail, Internet, or Telephone Order Merchandise Rule, 16 C.F.R. Part 435	A seller must have a reasonable basis to expect to ship within the time it states, or within 30 days if it states none. If it cannot, it must offer the buyer the option to consent to the delay or cancel for a prompt refund.
European Union	Consumer Rights Directive, Directive 2011/83/EU, Art. 18	Unless agreed otherwise, goods must be delivered without undue delay and within 30 days. If delivery fails, the consumer can set an additional period and then terminate the contract.
United Kingdom	Consumer Rights Act 2015, section 28	Unless a time is agreed, the trader must deliver without undue delay and no more than 30 days after the contract.
European Union and United Kingdom	Platform-to-Business Regulation, Regulation (EU) 2019/1150, Art. 4 (retained in UK law)	A marketplace that restricts or suspends a business user’s offers must give a statement of reasons at or before the time the restriction takes effect.

The FTC rule carries a lesson every FBM seller can use. It states that a seller without records of systems and procedures that assure timely shipment is presumed to lack a reasonable basis for its shipping promise. The handling-time audit and daily ship-by check we recommend are exactly that kind of record. Keeping them protects you with Amazon and with the regulator. On the contract side, the relationship with Amazon is governed by the Amazon Services Business Solutions Agreement and its program policies, and the reinstatement standard Amazon applies is the one written into those policies. In the EU and UK, the statement of reasons Amazon issues under the P2B Regulation is a useful document. It tells you exactly which metric and which offers the decision rests on, and your plan should answer it point by point.

What Never to Do to Hide Late Orders

When a metric turns red, some sellers look for a way to make the number move without changing the operation. Every shortcut below either creates a new violation or leaves a trail a reviewer will find.

Confirming shipment before the package exists. Marking orders as shipped with a tracking number for a label that has not been handed to a carrier misleads the buyer and Amazon. The tracking will show no movement, the delivery will still be late, and the confirmation record now contradicts the carrier record.
Uploading invalid or reused tracking. A tracking number that belongs to another package, a different carrier or no package at all is marked invalid. It damages Valid Tracking Rate and on-time delivery at the same time.
Cancelling orders you cannot ship on time. Cancelling instead of shipping late moves the problem into the Cancellation Rate, which has its own 2.5 percent limit. Our guide to the Amazon Cancellation Rate above 2.5 percent explains how those cancellations count.
Asking buyers to cancel. Pressuring a buyer to request cancellation so it does not count against you is the kind of conduct reviewers treat as metric manipulation.
Opening a second account to keep selling. Moving offers to another account while the first is restricted risks a related-account deactivation, which is far harder to reverse than a shipping metric.
Blaming the carrier in writing when the data says otherwise. If your confirmation timestamps are late, a carrier explanation will be checked against them and rejected.

Amazon’s help page does allow one honest correction. Before the delivery date, you can edit an order’s tracking information through Manage Orders by selecting Edit Shipment and re-confirming. Amazon states you should allow 72 hours for the report and the metric to reflect the change. Use that to correct a genuine typo. Do not use it to rewrite history.

The shortcuts sellers use to move a red Amazon shipping metric, set against what holds up on review. Compare each row before touching an order.

Daily Shipping Performance Routine

The prevention lesson for both metrics fits in one sentence. Confirm shipment the same day the label is bought, and set handling times your warehouse meets. The routine below turns that into a habit a small team can run in fifteen minutes a day.

Every morning

Pull the list of unshipped orders sorted by expected ship date. Anything due today goes to the front of the pick line.
Check that yesterday’s labels were all confirmed in Seller Central. Compare the count of labels bought with the count of confirmations. Any gap is a confirmation lag to fix before noon.
Look at the 10-day LSR. If it has moved since yesterday, download the report and find the orders that caused it.

Before the daily cutoff

Confirm every order shipped today with its carrier, service and tracking number. Amazon’s own best practices are to ship on or before the expected ship date, confirm as soon as the package is handed to the carrier, enter a valid tracking number and monitor the rate.
Flag any order that will miss its ship-by date. Decide now whether to expedite it, and contact the buyer if needed.
Verify the carrier pickup happened. A missed pickup is the most common reason a package confirmed on time is delivered late.

Every week

Compare handling time on each template or SKU with the actual time from order to carrier scan. Raise any setting your team does not meet.
Compare promised transit time with actual transit time by region and carrier service. Adjust templates where deliveries run late.
Review OTDR, remembering the 7-day lag, and check that Shipping Settings Automation and automated handling time are still active if you rely on them.

Handling time and cutoff audit checklist

Handling time on every shipping template matches the slowest normal day of the past month.
SKUs that take longer to prepare carry their own longer handling time.
The daily order cutoff in your settings matches the time your team stops packing.
Days the warehouse does not operate are reflected in your settings.
Holiday closures are set in advance.
Your shipping software confirms shipment automatically when a label is bought, and someone checks the sync daily.
Transit times on each template match the carrier service used for that region.
Dropship suppliers send tracking by a fixed hour each day, and late suppliers are removed from active SKUs.
One named person owns the daily check, with a backup for days off.

Amazon also states it may remove an individual offer when there is a history of multiple late shipments in a compressed period, even before the account-level rate crosses 4 percent. Those offers are reactivated through the Other policy violations section of Account Health. If you see single offers disappearing, treat it as the same warning. Our Amazon account health maintenance service runs this monitoring for sellers who want a second set of eyes on the metrics every week. For a focused look at acting on an early notice, see our guide to the Amazon late shipment rate warning, and for the wider picture of how customer experience metrics interact, see Amazon Voice of the Customer and CX Health.

Frequently Asked Questions

What is a good late shipment rate on Amazon?

Amazon targets a Late Shipment Rate under 4 percent. Lower is better, and a rate close to zero is realistic for a seller who confirms shipment the same day the label is bought. The rate is measured on seller-fulfilled orders only.

What is the Amazon on-time delivery rate target?

Amazon expects an On-Time Delivery Rate of at least 90 percent, measured over 14 days, for seller-fulfilled products on Amazon.com. It recommends 95 percent or higher. The rate is measured against your own promised “Deliver by” date before promise extensions.

What counts as a late shipment on Amazon?

A seller-fulfilled order with no shipment confirmation by its expected ship date counts as a late shipment. The physical handoff to the carrier does not decide it. The confirmation in Seller Central does.

Can a late shipment rate get my account suspended?

Yes, an LSR above 4 percent or an OTDR below 90 percent can lead to suspension of Fulfilled by Merchant privileges or deactivation of seller-fulfilled offers. Late orders also tend to raise A-to-z claims and negative feedback, which feed the Order Defect Rate.

How long is the late shipment rate measured?

Amazon measures LSR over 10-day and 30-day windows. The 10-day window reacts quickly to a new problem, and the 30-day window holds late orders for a month after they occur.

Get Help With an Amazon Late Shipment Deactivation

Most sellers with a clear cause can restore their shipping metrics with the routine above. Where we help most is the structural case. If the late rate comes from a fulfillment model that cannot meet the promise, such as dropshipping through a supplier you do not control, the fix is a change to the model, and the appeal has to show that change convincingly. We build the order-level evidence and the Plan of Action so a reviewer can approve it quickly.

Hand it to our Amazon suspension and reinstatement service, submit your case for a free assessment, or book a consultation to review your fulfillment setup before the next notice arrives.

Our Amazon account health maintenance specialists can rebuild your shipping workflow and draft the Plan of Action with you when seller-fulfilled offers are already down. Sellers facing a wider deactivation can review every marketplace reinstatement service we run.
