Ozon strengthens control over sellers' operational processes through updating key regulations. During the period from March 23 to March 29, the platform changed the terms of the contract, clarified the FBS rules and revised the approach to shipment planning. All three blocks have a direct impact on costs and sales stability.
The first change concerns the contract. The updated version focuses on the timing and payment of operations related to returns and removals. These parameters form a hidden part of the expenses, especially in categories with a high percentage of refunds. If the product stays in the warehouse longer than the prescribed period, paid storage or additional charges are included.
For sellers, this means the need for time control. The return becomes a process with a clear timer. Any delay within the team — in the warehouse, in approval, or in processing — automatically increases costs.
The second block of changes affects the FBS model. Ozon clarified the rules for handling goods and shipments, which came into force on March 25. The practical significance of these changes is related to operational sustainability. Even small adjustments to the list of acceptable goods or packaging requirements can lead to acceptance failures and logistical disruptions.
For sellers, this is a signal to immediately check the assortment and instructions for the warehouse. The responsibility for compliance with the rules remains on the seller's side, even if an external fulfillment is used.
The third change is related to the logic of the "recommended slot" in FBS. Now the approach to planning depends on the point of shipment — the sorting center or the point of receiving orders. This changes the very mechanics of planning: the slot becomes not just an interface element, but a key logistics management tool.
If the process is not synchronized, the risks of delays, postponements, and additional costs increase. For businesses, this means the need for a clear division of responsibility.: who is booking the slot, who is preparing the shipment and who controls the timing.
Taken together, the changes show the platform's strategy. Ozon reinforces the requirements for process discipline and shifts some of the operational risks onto sellers. In such conditions, those who establish systematic control over logistics, returns, and internal regulations benefit.
