Hello @Seller_fc8h9bkgpIR7p,

This is Josh from Amazon. Thank you for contacting our Forums!

I understand that you want to know more about the "New updates to our on-time delivery policy and shipping settings". First, important to mention that this will be effective on September 25, 2024, this way, our sellers will have time to adapt to the metric and its requirements in order to be on target.

Now, What is changing? Our updated policy requires a minimum 90% OTDR without promise extensions to have seller-fulfilled products listed on Amazon.com. An OTDR below 90% can result in restriction of your ability to have seller-fulfilled products listed. To help provide a positive customer experience, we recommend that you maintain a 95% or greater OTDR for all seller-fulfilled orders.

We are also changing the way we measure OTDR to now measure the percentage of your tracked seller-fulfilled units that were delivered on or before the seller-promised "Deliver by" date prior to promise extensions being added. Before this change, OTDR was measured after promise extensions were added. Promise extensions are additional days that we may add to the delivery date to account for logistical factors that may delay a delivery such as extreme weather, transportation network constraints, or recent history of a seller delivering shipments after their set delivery date. This policy does not apply to offers using the Fulfillment by Amazon (FBA) service because sellers are not responsible for on-time delivery promises for FBA orders.

To learn more about this, please go to Frequently asked questions about on-time delivery rate (OTDR)

And if you have additional questions or need more support, please contact our Seller Support team at any time.

Kind regards,

-Josh
