7-day delivery window required for Amazon FBA shipments

Starting from the 1st of September 2026, you must provide a seven‑day delivery window when you send international Fulfilment by Amazon (FBA) inventory shipments to fulfilment centres in the United Kingdom, Germany, France, Italy, and Spain.

This is one to take note of as it’s going to impact your shipments during Q4 and the last thing you want is your inventory sitting on a pallet because either Amazon aren’t expecting it or it’s turned up later then anticipated. A delivery window is an estimated date range of when you expect your shipment to arrive at Amazon’s fulfilment centre.

Providing accurate delivery windows helps Amazon prepare to receive your shipments so you can avoid processing delays. If you don’t provide accurate delivery windows, Amazon say that they may not be able to receive your inventory quickly, which could affect your ability to fulfil customer orders.

What’s the difference between “ship date” and “delivery window”? The ship date is the date on which you send the shipment to the fulfilment centre. The delivery window, which is specific to non-partnered-carrier shipments, is the date range during which the shipment is expected to arrive at the fulfilment centre.

How to prepare If you use a non-partnered carrier, Amazon recommend that you review their receiving times so you can provide accurate delivery windows. When you create an international shipment in the Send to Amazon workflow, you must include a seven‑day delivery window starting from the 1st of September.

If you use one of Amazon’s integrated solutions (Partnered Carrier program or Amazon Global Logistics), delivery windows will continue to be populated automatically.
