How long a buyer has to ship the return:
Once the return is accepted, we'll provide the buyer with a date by which they should ship the item and check that the return is on its way back to you. We may close the return if we don't see signals that the item is on its way back to you:
- eBay-Generated Labels: We may close the return request if the label is not printed within 10 business days. We may also close the return if the label is printed but we don't see tracking scans showing the item was shipped within 15 business days of when the label was provided.
- Seller-Provided Labels: If you provide non-eBay return labels and upload tracking we may close the return if we don't see tracking scans or signals from the buyer showing the item was shipped within 15 business days of when the label was provided. If tracking is not uploaded, we may wait up to 35 business days before closing the return.
- No Label Provided: If the buyer is responsible for return shipping, we may close the return if we don't see tracking scans or signals showing the item was shipped within 15 business days of the return being accepted. If you are responsible for providing return shipping and do not upload a label, we may wait up to 35 business days from the date the return was accepted before closing the return.
