If you sell on Amazon and ship your own orders, June 29, 2026 is a date worth marking. That's when Amazon starts enforcing stricter handling-time standards for seller-fulfilled (FBM) listings. The short version: the handling time you set on a SKU now has to match how fast you actually get the package to the carrier. Set it too optimistically and Amazon will notice.
What changes on June 29, 2026 Handling time is the window between a customer placing an order and you handing the package to UPS, USPS, or FedEx. Until now, sellers had a lot of room to set that number themselves. Starting June 29, Amazon expects your configured handling time to line up with your real fulfillment speed, and it's watching the gap.
Your two options for setting handling time Amazon gives FBM sellers two ways to stay compliant:
Automated Handling Time. Amazon sets the handling time for each SKU based on your recent shipping history. Turn this on and you get Late Shipment Rate protection in return.Manual SKU-level handling time. You set the number yourself, and Amazon monitors it on a rolling basis. If a SKU consistently ships at least a day faster than the handling time you set, Amazon flags the listing as inaccurate.What happens if your handling times are off If your settings don't reflect reality, Amazon will step in, take over the handling time for that SKU, and give you 180 days of Late Shipment Rate protection while it recalibrates. That sounds forgiving, but losing control of your handling time has a cost. Inaccurate or late shipments hurt your account health, drag down your delivery promises, and can lead to listing restrictions or suspension if the problem keeps up.
One more change affects Premium Shipping listings: the on-time delivery requirement drops to 93.5%, but the review period moves from monthly to weekly. A bad week now shows up faster.
Why Amazon is tightening FBM now Two things are pushing more sellers toward FBM at the same time. On April 17, 2026, Amazon added a 3.5% fuel and logistics surcharge to US FBA fulfillment fees, which works out to roughly 17 cents per unit on average. For brands already watching margins, that nudged FBA further out of reach and made fulfilling orders themselves look better. More FBM volume means Amazon cares more about whether those sellers actually deliver on time, which is where the handling-time crackdown comes in.
What to do before June 29 You have a few days. Here's where to spend them:
Pull your current handling-time settings and compare them to how fast you actually ship. Decide whether Automated Handling Time or manual settings fit your operation. If your ship speed is steady, automation plus Late Shipment Rate protection is the safer bet. Tighten the actual gap between order and carrier handoff. Accurate settings only help if your real speed backs them up. Upload tracking promptly. Late or missing tracking feeds straight into your defect metrics.
