Quick answer: Amazon’s late shipment rate is the percentage of seller-fulfilled orders that were not confirmed as shipped by the expected ship date, measured over 10-day and 30-day periods. Amazon requires it to stay under 4%. Above that, Amazon may suspend your Fulfilled by Merchant selling privileges or deactivate offers with high late shipments. To fix it, ship and confirm by the expected ship date with valid tracking, set handling times you can meet, and appeal from the Account Health page if offers or privileges were removed.
Late shipments do more than move one metric. Amazon notes that orders confirmed late can lead to more A-to-z Guarantee claims, negative feedback, and buyer contacts, which feed other account health measures. This guide explains how Amazon calculates the late shipment rate, the most common causes, and how to recover, using Amazon’s own help pages.
What the Late Shipment Rate Measures
Amazon defines the late shipment rate (LSR) as how often sellers ship orders after the expected handling time. An order is late when there is no shipment confirmation by the expected ship date. LSR is the percentage of orders shipped late out of total orders, measured over 10-day and 30-day periods, and it applies only to seller-fulfilled orders. Amazon adjusts expected ship dates for national holidays.
Shipping Metrics at a Glance
| Metric | Amazon target | Measured over | What it tracks |
|---|---|---|---|
| Late shipment rate | Under 4% | 10 and 30 days | Orders not confirmed as shipped by the expected ship date |
| Cancellation rate | Under 2.5% | 7 days | Orders cancelled by the seller, including auto-cancels for unconfirmed shipments |
| Order defect rate | Under 1% | 60 days | Orders with negative feedback, A-to-z claims, or chargebacks |
Why Late Shipment Rates Rise
Shipping on time but confirming late
Amazon measures confirmation, not just the physical shipment. A package handed to the carrier on time but confirmed in Seller Central later still counts as late.
Handling times you cannot meet
If your handling time setting is shorter than your real processing time, orders will miss the expected ship date even when your team is working normally.
Stock that is not on hand
Waiting on a supplier or a transfer between locations pushes orders past the ship date.
Tracking errors
Amazon lists common tracking problems: wrong or blank tracking numbers, special characters, misspelled carrier names, a carrier name that does not match the tracking number, and carriers not integrated with Amazon.
How to Bring the Rate Down
Amazon’s best practices for a healthy LSR are to:
- Ship orders on or before the expected ship date
- Confirm orders as soon as you hand the package to the carrier
- Enter a valid tracking number
- Monitor your late shipment rate regularly
Get tracking right
Select the carrier and service from the drop-down in Manage Orders, check that the tracking number matches the carrier, and confirm or update tracking before the order is delivered. Amazon says tracking added after delivery does not help the customer and does not count toward your valid tracking rate.
Fix tracking before delivery
To edit tracking, go to Manage Orders, search the order ID, select Edit Shipment, update the tracking, and re-confirm. Amazon says to allow 72 hours for the report and metric to reflect changes.
How to Check Your Late Shipment Rate
- Go to Account Health.
- In the Shipping performance section, select View details.
- Select Late shipment rate and then Download report.
How to Appeal a Late Shipment Suspension
Amazon says that if your seller-fulfilled offers are deactivated for missing the LSR requirement, you can appeal from the Account Health page by selecting Submit appeal and following the instructions. Amazon also removes individual offers when there is a history of multiple late shipments in a short period; those can be reactivated through the Other policy violations section of the Account Health dashboard.
What to include
Explain the root cause of the late confirmations, the changes you made with dates, such as adjusted handling times, a new confirmation routine, or a carrier integration, and how you will keep the rate under 4%.
If an Amazon error caused the defects
Amazon’s Account Health Support FAQ notes that if you believe a system error, such as incorrect handling times, generated false late shipment defects, you should say so specifically when contacting support and provide evidence.
Our Amazon suspension and reinstatement team handles performance metric appeals. To keep shipping metrics in range, see our Amazon account health maintenance service.
