An On-Time Delivery Rate (OTDR) suspension occurs when Amazon determines that a seller consistently fails to ship orders within the promised time frame, which negatively impacts the customer experience. Amazon holds sellers to high standards to ensure customers receive their products promptly. If a seller’s On-Time Delivery Rate falls below the required threshold—typically 97%—Amazon may suspend the account to maintain marketplace integrity.

The On-Time Delivery Rate measures how well sellers adhere to their stated shipping timelines. When an order is placed, the seller commits to a shipping and delivery schedule. If the seller consistently misses these deadlines or fails to provide valid tracking information, it reflects poorly on their performance and can lead to a suspension.
