A Return Timeframe is the time limit established by the Supplier in which a customer must register a return request for specific reasons, such as wrong product, wrong quantity, or damaged product. 

Return Timeframe countdown starts when the order is confirmed/marked by the Supplier as shipped to the customer plus the maximum shipping time specified by the Supplier

If a tracking number with a delivery date is available, the return timeframe countdown starts from the delivery date.

If the supplier has a return timeframe of, let’s say, 15 days, like the one above, then this means the customers can change their mind about the purchase and can return it within 15 days from the day they received the products.

Keep in mind that this return timeframe can be different from one supplier to another and from one product to another.
