Amazon Is Taking Control of Handling Times on June 29. Here Is What Seller-Fulfilled Brands Need to Do Now.
Starting June 29, 2026, Amazon is enforcing a new requirement for every seller-fulfilled SKU in the US: your stated handling time must accurately reflect how fast you actually ship.
If it does not — and Amazon can tell — they will manage it for you.
This arrives eight days after Prime Day ends. But the preparation needs to happen before Prime Day, not after.

What Amazon Is Actually Enforcing
Starting June 29, sellers must ensure that the handling time of their seller-fulfilled SKUs accurately reflects their actual shipping speed. Handling time is considered accurate when the actual time consistently matches the configured handling time for each SKU.
The direction of enforcement is worth noting. This is not about sellers shipping late. It is about sellers stating longer handling times than they actually need.
SKUs consistently shipped at least one day faster than stated will be flagged and need to be updated within 30 days. If accurate handling time is not provided, Amazon will start managing those SKUs on the seller’s behalf and provide Late Shipment Rate protection for 180 days.
Amazon’s own data supports why they care: more than 87% of seller-fulfilled orders in the US are processed within one day, yet many sellers still set longer handling times for certain SKUs, causing slower estimated delivery dates to appear on product pages. Amazon cites an average 5% sales increase for every one-day improvement in promised delivery time. When your stated handling time is longer than your actual performance, you are leaving that 5% on the table voluntarily.
Two Ways to Comply
The first option — and Amazon’s explicit recommendation — is enabling Automated Handling Time. AHT sets handling time for your SKUs based on your recent shipping history and provides Late Shipment Rate protection. It can be enabled now in your Shipping settings. For most standard seller-fulfilled operations, this is the lowest-friction path.
The second option is maintaining accurate SKU-specific handling times manually. Amazon will monitor these SKUs for over 30 days. If a SKU is consistently shipped at least one day faster than stated, it will be flagged, and you will have 30 days to update it. If accurate handling time is not provided after that, Amazon takes over management of that SKU for 180 days.
This requirement does not apply to custom, handmade, and Heavy and Bulky less-than-truckload shipments. If your business model involves production time before shipping, contact Seller Support before June 29 to confirm your compliance options.
The Seller Frustration — and Why It Has Merit
The policy has generated pushback, and not without reason.
Amazon starts measuring handling time when a shipping label is created, not when the package is handed to the carrier. For sellers who pack orders on weekends for Monday carrier pickup, this creates a structural gap between label creation and actual shipment.
The other friction point is the incentive structure. Sellers who consistently ship faster than promised — the classic under-promise, over-deliver approach — are being flagged for doing right by customers. Shipping one day faster than your stated handling time consistently triggers a forced update. Good performance leads to tighter constraints.
Both concerns are real. Amazon’s position is that accurate delivery dates drive purchase decisions and inflated handling times hurt conversion. That logic is sound. The implementation friction for sellers with genuine operational variability remains an unresolved tension.
What to Do Before June 29
Check whether Automated Handling Time is already enabled. If it is, no action is required — Amazon has confirmed compliance for AHT-enabled accounts.
If you manage handling times manually, audit your SKU-specific settings now. Compare your actual shipping performance against configured handling times. Any SKU where you consistently ship faster than stated should be updated before June 29 — both to avoid being flagged and to show shoppers your actual delivery speed during Prime Day traffic.
Handling time accuracy is one of those operational details that looks minor on a spreadsheet and shows up meaningfully in conversion rate, Late Shipment Rate, and account health. June 29 is ten days away.
