Amazon to Revise Self-Fulfillment Handling Time Requirements Effective June 29

May 29, Amazon announced that starting June 29, 2026, it will implement new handling time management requirements for Merchant Fulfilled Network (MFN) products. Concurrently, the company will raise the delivery speed standards for the Seller Fulfilled Prime (SFP) and Premium Shipping programs. These changes aim to further strengthen consumer trust in delivery promises and optimize the Prime member service experience. Under the new rules, sellers must ensure that the handling time set for self-fulfilled SKUs in their back-end systems aligns with their actual shipping capabilities. The platform will conduct performance checks based on relevant data. Amazon advises sellers to promptly conduct a comprehensive review of the handling time settings for their currently listed SKUs and make adjustments based on the actual time required for warehousing, picking, and packing operations. This is to avoid an increase in late shipment rates due to overly aggressive handling time settings, which could negatively impact account performance metrics. [This article is sourced from Ebrun Go.
