Improving Amazon's Late Shipment Rate: identifying delays and reviewing dispatch procedures

Has your Late Shipment Rate for self-fulfilled orders been creeping upward? You shipped on time, yet the order still counts as late. This article is for sellers in that situation. We walk through how the metric is judged, how to pull a list of your late orders, how your expected ship date is set, how to separate out the root causes, how to review your dispatch procedures, and how to build a plan of action if your seller-fulfilled listings are suspended.

How the Late Shipment Rate is calculated: judged by when the shipment confirmation was sent

The Late Shipment Rate (LSR for short) is the percentage of orders, out of your orders from the past 10 or 30 days, whose shipment confirmation was sent after the expected ship date. It covers seller-fulfilled orders only; FBA orders are not included.

What matters is that the metric isn't judged by when the package was physically handed off, but by when you sent the shipment confirmation. Confirming shipment is the action, in Seller Central, of marking an order as shipped and entering the carrier and tracking number; even if the carrier collected the package on time, the order counts as late if the confirmation is sent after the expected ship date.

This article is based on Seller Central Help and official materials as of September 2026. Policies and on-screen labels can change, so please also check your actual screens and the latest Help content.

The benchmark is "under 4%" — don't cut it close to the line

Under Amazon's policy, sellers are required to keep their Late Shipment Rate at 4%, and exceeding it can lead to selling privileges being restricted or removed. The current Japanese Help page says "4% or below," while a 2021 official document and the US Help page say "under 4%," so it's safest to treat under 4% as your working target.

The fewer orders you have, the more each late shipment weighs. To stay under 4%, your number of late orders must be under "orders in the period × 0.04." For example, with 60 orders over 30 days, 2 late orders comes to about 3.3%, and 3 comes to 5% — the third order pushes you over the benchmark (this is a hypothetical calculation, not an actual case). By the same calculation, staying under 4% allows no late orders with 25 orders, at most 1 with 50 orders, and at most 3 with 100 orders.

Late shipments are described as something that can lead to A-to-z Guarantee (Amazonマーケットプレイス保証) claims, low ratings, and more customer inquiries. The main enforcement action is suspension of your seller-fulfilled listings, but how far over the threshold or for how long triggers which action has not been made public.

The Late Shipment Rate is also one of the eligibility requirements for same-day dispatch, which requires maintaining a Late Shipment Rate under 4% and an On-Time Delivery Rate of 97% or higher continuously over 30 days.

Other metrics under the same "Shipping Performance" section

Metric	Period	Benchmark	What it measures
Late Shipment Rate	10 or 30 days	Under 4%	Percentage of orders whose shipment confirmation was sent after the expected ship date
Cancellation Rate (Pre-fulfillment Cancel Rate)	7 days	Under 2.5%	Percentage of orders canceled by the seller (including orders Amazon automatically canceled because no shipment confirmation was sent)
Valid Tracking Rate	30 days	Not below 95%	Percentage of shipments with a valid tracking number (calculated by category)
On-Time Delivery Rate	Check on screen	Above 97% recommended	Percentage of orders delivered by the estimated delivery date. In Japan, Amazon currently states there is no penalty for falling short

The 0–1,000 Account Health Rating doesn't list shipping-related metrics among the policies it covers. Even if your rating shows "Healthy," check your Late Shipment Rate separately (how to check your Account Health Rating).

Assess your current situation: pull a report to find your late orders

Before taking action, get a clear picture of which orders were late and by how much. Here's how (button names may change):

1. Open "Account Health" in Seller Central
2. Click "View details" in the "Shipping Performance" section
3. On the "Late Shipment Rate" tab, scroll down and select "Download report"

Timestamps in the report are in UTC (Coordinated Universal Time); Japan time is UTC plus 9 hours. Orders and shipment confirmations from late at night through early morning can look like they fall on the wrong date, so convert to Japan time before cross-checking against your internal records. It hasn't been disclosed which of the 10-day or 30-day figures is used for warnings or suspension decisions and how, so keep a record of both numbers.

How the expected ship date is set: work backward from your own settings

The expected ship date is calculated by adding your handling time to the order date. Handling time (リードタイム, lead time) is the number of business days from when an order is confirmed to when you hand the package to the carrier. For standard shipping, the "order cutoff time" determines which day an order counts toward, and the count also changes with your weekend business-day and holiday settings. You can check the expected ship date for each order in the order details, and shipping by that date is an obligation under the Amazon Services Business Solutions Agreement.

Example: how the order cutoff time shifts the expected ship date by a day

Help gives the following example for an order placed at 3:40 a.m. on June 14, with handling time set to 1 day.

Order cutoff time	Expected ship date
Midnight	June 15
6:00 a.m.	June 14 (the day the order was placed)

The range you can set is 2:00 p.m. to 9:00 p.m. if handling time is 0 days, or midnight to 6:00 a.m. if it's 1 day or more. Check your own cutoff time under "Order Handling Settings (注文の出荷設定)" in your shipping settings.

Settings that affect the expected ship date, and where to find them

Setting	Location	What to review
Default handling time	Settings (設定) → Shipping Settings (配送設定) → General Shipping Settings (一般配送設定) → Handling Time (出荷作業日数)	Set to 1 day when you start selling. Professional sellers can choose same-day, 1 day, or 2 days (same-day requires meeting the eligibility conditions described above). Can be changed only once every 24 hours
Handling time per product	"Edit Details" in Manage Inventory (在庫管理), or a listing file	1–30 days per SKU. Leaving it blank in a listing file reverts it to the default
Business days (weekends)	Shipping Settings → "Edit" for your ship-from location → "Fulfilled by Seller"	Monday–Friday is required; Saturday and Sunday are optional
Holidays	General Shipping Settings → "Holiday Settings" widget	Professional sellers only. Register your own non-business days via "Add a custom holiday"
Order quantity limit	The handling time edit screen	Orders beyond the limit get an extra day added to handling time

Transit time is a setting related to the On-Time Delivery Rate, so when addressing your Late Shipment Rate, focus your review on the settings listed above.

Analyze the causes of delay across three layers: commitment, operations, and reporting

Go through the orders you've recorded one by one and sort the cause of each into one of the following three layers.

Category	Typical situation	Sign to look for	Main things to review
Commitment delay	Your configured expected ship date is earlier than your actual pace of work	Delays cluster around weekend, holiday, or late-night orders	Handling time, cutoff time, business days, holidays
Operations delay	Out of stock, waiting on a restock, short-staffed, missing carrier pickup	Concentrated around specific SKUs, days of the week, or busy periods	Inventory, which products you list, work procedures, order quantity limit
Reporting delay	Forgetting to send the confirmation, batching it for the next day, a tracking-number error	Pickup was on time but only the confirmation is late	Who sends confirmations, when, and how they're entered

Commitment delay: your settings haven't kept up with reality

This covers situations such as: non-business days that aren't registered in your holiday settings, weekends set as business days even though no one is scheduled to ship on Saturdays or Sundays, or made-to-order products that take longer to produce still being subject to the default handling time. Changes to holiday settings take effect for new orders 15 minutes to 24 hours after saving, and the expected ship date for orders already placed doesn't change, so ship those by their original expected ship date.

Operations delay: inventory and staffing can't keep up with orders

This covers situations such as: leaving an out-of-stock product listed, listing a special-order item with an unpredictable delivery time under the same terms as items you have on hand, or a sale pushing order volume past your processing capacity. Amazon recommends listing only products you can ship by the expected ship date (including that day), and keeping enough stock on hand ahead of busy periods and for products you expect to be recommended or featured. For products where you consistently can't keep up, switching to FBA is also an option.

Reporting delay: the package shipped, but the confirmation is late

This covers situations such as: batching shipment confirmations to send the next morning, no one sending them because the responsible staff member was off, or a tracking-number entry error pushing the confirmation to later. Since the package has already shipped, this is the layer that's easiest to fix by reviewing your procedures. Related steps are also covered in what to review when your shipment confirmation and actual dispatch don't match up.

For orders where more than one layer applies, flag them under every layer that applies. Once you have counts for each layer, your priorities become clear, and a plan of action can point to a root cause backed by numbers.

Reviewing your dispatch procedures: aligning how staff work with how settings are configured

Once you've sorted the causes, review both your staff procedures and your settings. Steps 1–2 mainly address "reporting delay," while Steps 3–6 address "commitment delay" and "operations delay."

STEP 1. Check your orders at a set time every business day

Your agreement with Amazon also requires checking your orders at least once every business day. Amazon advises against relying solely on order-confirmation emails, and recommends checking Manage Orders or an order report once a day for orders not yet shipped. Orders marked "Pending" should not be shipped, even if the buyer contacts you about them.

STEP 2. Send the shipment confirmation right after pickup, before the expected ship date passes

Send the shipment confirmation after you hand the package to the carrier. If it isn't sent within 4 hours of pickup (or from the drop-off time for mailbox drop-offs), tracking information is said not to sync, making the package untrackable — but that's a guideline for tracking sync specifically. The Late Shipment Rate itself is judged purely by whether the confirmation was sent by the expected ship date. If pickup falls in the evening of the expected ship date, send the confirmation before that date passes. To send it, go to "Confirm Shipment" in Manage Orders (注文管理) and enter the ship date, carrier, tracking number, and ship-from address (Professional sellers can also send confirmations in bulk via file).

• Since January 19, 2022, for eligible services from Japan Post, Yamato Transport, and Sagawa Express, a shipment confirmation is blocked if the tracking number entered is invalid
• Fix an incorrect entry within 24 hours via "Edit Shipment Info" → "Confirm Shipment" again (changes are not allowed once the estimated delivery date has passed)
• Buying a label through Buy Shipping automatically marks the order as shipped, so hand the package to the carrier right after purchase

Tracking numbers also affect your Valid Tracking Rate. See how to improve your Valid Tracking Rate for related precautions.

STEP 3. Align your handling time with reality

Under Inventory (在庫) → "Manage Seller Fulfilled Inventory" → the "Shipping Settings" tab, you can check the handling time set for each SKU and where it comes from, and you can also pull a "Handling Time Report." The "Recommendations" tab shows suggested handling times for SKUs where the actual average doesn't match your setting, updated on the first of the following month. That said, handling time is meant to represent the business days needed for picking, packing, and applying labels, and Amazon advises against padding it with a "buffer" for restocking or the holiday season. Check for yourself whether adding days for waiting on inventory to your handling time is consistent with this guidance. For special-order items you can't confidently ship by the expected ship date, hold off on listing them until you have stock secured.

STEP 4. Align your cutoff time, business days, and holidays with how you actually operate

Set your cutoff time and weekend business days to match the days and hours your staff can actually ship (Seller Fulfilled Prime listings require 6 business days a week). Register your own non-business days in your holiday settings as soon as they're decided (you can only remove one up until 24 hours before that date).

STEP 5. Use an order quantity limit to route around orders beyond your capacity

Setting an "order quantity limit" automatically adds one day to the handling time for orders that come in after you've hit the limit. In Help's example, with a limit of 100 orders and 1-day handling time, the 101st order gets 2 days. This doesn't apply to orders under Seller Fulfilled Prime or related fast-delivery programs.

STEP 6. Decide in advance what to do ahead of closures or bad weather

For periods you can't ship, you can set your listings to inactive via "Settings" → "Account Info" → "Store Status" → "Vacation Settings" (on some screens, "Listing Status" under "Selling Account Information"). Going on vacation doesn't automatically cancel existing orders, so finish shipping those before you go inactive. Even while inactive, respond to return requests and buyer emails within 24 hours. If a natural disaster is expected to delay pickups, Amazon's guidance is to extend your handling time, switch orders under fast-delivery programs to standard shipping, and notify buyers on existing orders of the delay. Amazon states that it takes extenuating circumstances into account in recent performance reviews once contact with the buyer is confirmed, so reach out using a message method that leaves a record.

An option to consider: the Automated Fulfillment Program (AFP, 自動出荷設定プログラム)

The Japanese Help page states that the Late Shipment Rate doesn't apply to regular orders from sellers enrolled in the Automated Fulfillment Program (AFP). Eligibility is described as requiring Automated Handling Time (AHT, 出荷作業日数の自動設定) to be enabled, along with Automated Shipping Settings (SSA, 配送設定の自動化) being enabled (or an accurately maintained manual transit time setting).

Staying eligible requires three things: keeping AHT enabled, sending an on-time shipment confirmation with a valid tracking number on every order, and keeping your transit time accurate. If you can't use SSA and set transit time manually, a gap of under 0.0 days or 1.1 days or more, as shown on the Estimated Delivery Date dashboard, is treated as inaccurate.

We haven't been able to confirm the enrollment process or its scope. Check whether you're enrolled by seeing whether the Late Shipment Rate is being counted in the Shipping Performance section of your Account Health page, and until you can confirm this, manage your operations as though it still applies to you.

Responses that backfire when you're trying to protect the number

Rushing to bring the number down can trigger a different violation or make another metric worse.

• Sending the shipment confirmation before handing off the package: This counts as Premature Confirm Shipment Abuse (PCSA, 出荷通知事前送信の乱用) and can lead to enforcement action. Amazon explicitly lists sending a confirmation just to satisfy the Late Shipment Rate as prohibited.
• Switching to canceling orders to avoid a late shipment: This just shifts the problem to your Cancellation Rate (benchmark: under 2.5%). Avoid canceling to manage the numbers, and instead manage your inventory and listings so unshippable orders don't arise in the first place. When cancellation is unavoidable, choose an accurate reason and cancel it yourself as the seller. Steps for this are covered in addressing your Pre-fulfillment Cancel Rate.
• Asking the buyer to cancel: For orders you can't ship for reasons on your end, you're not supposed to ask the buyer to do this.
• Leaving an order without sending a confirmation: An order for which no confirmation is sent within 7 business days of the expected ship date is automatically canceled, and even if you shipped the item, you won't be paid. This automatic cancellation also counts toward your Cancellation Rate (how the days are counted differs across Help pages, so check the details in Manage Orders).
• Continuing to sell under a new account: Using multiple selling accounts to get around Late Shipment Rate enforcement is not permitted under Amazon's policies. Avoid creating or using a separate account for the purpose of evading a suspension.

A delay can cascade into other metrics too. A shipment whose confirmation is sent after the estimated delivery date counts as late under the On-Time Delivery Rate, and if it doesn't arrive by the latest estimated delivery date, an A-to-z Guarantee claim may be approved automatically, which can affect your Order Defect Rate. Also check how to review your Order Defect Rate.

From suspension risk to submitting a plan of action: how to respond at each stage

When you're at risk of suspension: the banner quiz

When your seller-fulfilled listings are at risk of suspension, affected sellers see a banner at the top of the Account Health page with a five-question quiz on the Late Shipment Rate policy. It isn't shown to every seller, and no deadline for answering it is stated, so follow the instructions on your screen and in your notifications. You still need to keep meeting the target after you pass.

If your seller-fulfilled listings are suspended: submit a plan of action

If you're suspended, submit a plan of action (パフォーマンス改善計画) via "Submit an Account Health appeal" on the Account Health page. If your entire account has been suspended, submit the questionnaire and supporting documents via "Reactivate your selling account." The review period and reinstatement timing aren't guaranteed, so proceed by checking the instructions and deadline in your notification. Checking the scope of a suspension is covered in what to check when your seller-fulfilled listings are deactivated.

Amazon's guidance for appeals covers three points: write it factually and concisely, identify the root cause, and show the actions you took along with the dates and supporting documents. Below is a sample outline for a case where "reporting delay" and "commitment delay" overlap. This is a hypothetical example, not an actual case, so replace the ◯ marks with the facts from your own report.

[Root cause] Reviewing our Late Shipment Rate report for ◯/◯ through ◯/◯, we found ◯ late orders out of ◯ total orders. Of these, ◯ orders were picked up within the expected ship date, but the shipment confirmation was sent the following business morning, batched with other orders. The remaining ◯ orders had an expected ship date that fell on a non-business day that wasn't registered in our holiday settings.
[Corrective action] On ◯/◯, we registered the non-business day in our holiday settings and reviewed every order without a confirmation sent.
[Preventive measures] We assigned a staff member to send shipment confirmations right after pickup, and added a step where a second staff member checks for unconfirmed orders after the final pickup of the day. We now register the following month's non-business days at the start of each month.

Using a template as-is won't convey what actually happened or what you changed. For guidance on how to structure it, see how to build a plan of action.

A routine to prevent recurrence

Split your checks by frequency and build them into the responsible staff member's regular tasks.

Frequently asked questions

Q. Does this also affect FBA orders or my whole account?

A. The Late Shipment Rate itself doesn't include FBA orders. That said, Amazon states that metric or policy violations can sometimes lead to a temporary suspension of your entire account, so check the scope of any suspension in your notification.

Q. If I go over 4%, will I be suspended right away?

A. Whether suspension is immediate or there's a grace period hasn't been made public. As soon as the number starts climbing, move quickly to identify the cause.

Q. How long does a late order affect the number?

A. Since it's calculated from orders in a 10-day or 30-day window, an order should stop counting once it falls outside that window. That said, exactly when you get back under the threshold depends on your subsequent order activity and can't be stated as a general rule.

Q. What should I set if I'm closing for a few days?

A. Besides the vacation setting from Step 6, you can also specify vacation days added to your lead time via "Edit Details" in Manage Inventory. However, you can't specify more than 30 days, and this can't be set for FBA products. Also note that an order that can't ship within 30 days of the order date is automatically canceled. Change it back to your normal number of days once you reopen.

Summary

• The Late Shipment Rate is counted by when the shipment confirmation was sent. Treat under 4% as your benchmark, and check both the 10-day and 30-day figures
• Pull a report to find your late orders, then sort them into the three layers of commitment, operations, and reporting
• Align your handling time, cutoff time, business days, and holidays with reality, and use an order quantity limit to manage overflow
• Never send the shipment confirmation before handing off the package. Don't try to manage the number through cancellations — manage your inventory and listings so unshippable orders don't occur
• If you're suspended, submit a plan of action that lays out the facts from your report and the dates you changed your settings

Rather than chasing the number alone, fixing the mechanism behind each delay one by one is what prevents it from happening again.
