Amazon FBA 7-Day Delivery Window in the UK: What Sellers Must Do Before 1 September 2026

For established Amazon sellers handling 500+ orders each month, the inbound planning change taking effect on 1 September 2026 needs attention now.

From that date, international FBA inventory shipments sent by non-partnered carriers to Amazon fulfilment centres in the UK, Germany, France, Italy and Spain must include a seven-day delivery window in the Send to Amazon workflow.

This is the key distinction:

• International shipment
• Non-partnered carrier
• Destination fulfilment centre in one of the five named countries
• Seven-day estimated arrival range entered in Send to Amazon

Sellers using an Amazon Partnered Carrier or Amazon Global Logistics are not affected in the same way. Their delivery windows are populated automatically through the integrated solution.

The change has been reported by ChannelX and Ebrun. Amazon’s related Seller Central receiving-timeliness discussion explains how delivery windows support the receiving process.

What is the Amazon FBA 7-day delivery window?

A delivery window is the estimated date range when Amazon expects your shipment to arrive at its fulfilment centre.

It is not the date your shipment leaves your warehouse.

Delivery window vs ship date

Term	Meaning
Ship date	The date you dispatch the shipment from your origin location.
Delivery window	The seven-day date range when the shipment is expected to arrive at Amazon’s fulfilment centre.

For example:

• Your cartons leave a supplier in Asia on 1 September.
• The ship date is 1 September.
• Your realistic transport, customs and carrier-handling timeline suggests arrival between 18 and 24 September.
• The delivery window is 18–24 September.

Do not select a date range simply because it looks commercially convenient. Use your actual transport lead times and Amazon’s receiving data.

Who is affected?

Shipment or carrier type	Manual seven-day window from 1 September 2026?	What to do
International FBA inventory sent to the UK using a non-partnered carrier	Yes	Enter an accurate seven-day delivery window in Send to Amazon.
International FBA inventory sent to Germany, France, Italy or Spain using a non-partnered carrier	Yes	Apply the same process for the relevant destination.
Amazon Partnered Carrier	Not in the same way	Delivery information is integrated and populated automatically.
Amazon Global Logistics	Not in the same way	Delivery information is integrated and populated automatically.
Domestic UK FBA shipment	Not newly affected by this international change	Follow the applicable domestic workflow and delivery-window requirements.
Shipment already managed through an integrated Amazon solution	Not in the same way	Confirm the carrier setup and follow the workflow shown in Seller Central.

The September change is specifically important for international inbound inventory using non-partnered carriers.

If you are unsure which category applies to your shipment, confirm the carrier type before creating the shipment plan.

Why the date matters

Amazon says accurate delivery windows help its fulfilment centres prepare for receiving.

Inaccurate information may contribute to:

• Receiving delays.
• Slower inventory check-in.
• Restrictions on receiving.
• Stock remaining unavailable while the shipment is processed.

Amazon does not promise a particular outcome when a seller submits a delivery window. The practical point is simple: your window should reflect the shipment’s likely arrival, not the date you want it to arrive.

Amazon has also brought forward some Q4 2026 inbound deadlines. Do not rely on generic peak-season assumptions. Check the current dates and requirements in your own Seller Central account.

The real risk is not only entering the wrong date

The seven-day requirement is an operational issue, not merely a data-entry task.

Your stock may be:

• Still in transit when the delivery window closes.
• Held during customs clearance.
• Delayed by a carrier handover.
• Waiting for an appointment or receiving capacity.
• Arriving at Amazon without the correct preparation.
• Unavailable for sale while you approach a stock-out.

That can create a gap between inventory leaving your supplier and inventory becoming available for customer orders.

If your sales velocity is high, a few days of uncertainty can affect:

• FBA availability.
• Advertising efficiency.
• Buy Box performance.
• Marketplace revenue.
• Customer delivery expectations.
• Your ability to plan replenishment with confidence.

The answer is not to guess a wider date range. The answer is to understand your true lead time and create a controlled inbound process.

Practical preparation guide for the FBA delivery window UK change

1. Identify your carrier type

Start with the shipment itself.

Confirm whether you are using:

• A non-partnered freight forwarder.
• A non-partnered small-parcel carrier.
• A non-partnered less-than-truckload carrier.
• Amazon Partnered Carrier.
• Amazon Global Logistics.

If the shipment uses a non-partnered carrier and is international inbound to the UK, plan to enter the seven-day window manually.

2. Review Amazon’s receiving-timeliness data

Amazon recommends reviewing available receiving information before selecting the window.

Compare this with your own records:

• Dispatch date.
• Port or airport departure.
• Customs clearance time.
• UK carrier handover.
• Final-mile transport.
• Delivery appointment or booking time.
• Amazon check-in and receiving history.

Your previous shipment history is valuable. Use real data rather than a standard supplier estimate.

3. Calculate realistic transport time

Build the delivery estimate from the complete journey.

Include:

• Production completion.
• Collection from the supplier.
• Export documentation.
• Main transport.
• Customs clearance.
• Import handling.
• UK carrier movement.
• Delivery to the Amazon fulfilment centre.

Then choose the seven-day window that best reflects the expected arrival date.

Do not confuse “ready to ship” with “likely to arrive at Amazon”.

4. Prepare paperwork before dispatch

Your shipment file should be verified before the cartons leave the origin.

Depending on the route and product, this may include:

• Commercial invoice.
• Packing list.
• EORI details.
• Commodity codes.
• Customs information.
• Carton count.
• Pallet details.
• Product and shipment references.
• Carrier booking information.

Your carrier remains responsible for the transport process. Your responsibility is to provide accurate, complete information and confirm that the shipment plan matches the physical stock.

5. Verify dimensions, weights and carton details

Small discrepancies can create avoidable handling issues.

Check:

• Product dimensions.
• Product weight.
• Carton dimensions.
• Carton weight.
• Units per carton.
• Total carton quantity.
• Pallet quantity, where applicable.
• Box content information.
• Carton labels.

A verified shipment plan gives your carrier and Amazon a clearer receiving picture.

6. Complete preparation before stock becomes urgent

For sellers searching for Amazon FBA prep UK or an FBA prep centre UK, preparation needs to happen before inventory becomes a critical replenishment.

Confirm that each product is ready for Amazon’s requirements, including:

• FNSKU labelling.
• Polybagging where required.
• Suffocation warnings where applicable.
• Carton standards.
• Carton labels.
• Product bundling and multi-unit configurations.
• Correct SKU-to-product mapping.

A shipment that arrives without the correct preparation may require further handling before it can move through the intended process.

7. Build a UK inventory buffer

A UK buffer can provide useful control when international transport is variable or demand is increasing.

It may be suitable when:

• Your supplier lead time is long.
• Your sales volume is consistent.
• Your products have predictable demand.
• You regularly send replenishment shipments.
• Your stock is split between FBA and D2C.
• You need to complete FNSKU labelling in the UK.
• You have seasonal Q4 demand.
• You want overflow stock closer to the final fulfilment route.

A buffer does not remove your responsibility to comply with Amazon’s Send to Amazon workflow for shipments that are in scope. You must still provide the required delivery window for an international shipment sent by a non-partnered carrier.

The buffer is a stock-control solution. It is not a substitute for accurate Amazon shipment information.

Frequently asked questions

What is the Amazon delivery window September 2026 change?

From 1 September 2026, international FBA inventory shipments sent by non-partnered carriers to fulfilment centres in the UK, Germany, France, Italy and Spain must include a seven-day delivery window in Send to Amazon.

Does the seven-day window apply to every Amazon FBA shipment?

The specific change concerns international shipments to the five named countries using non-partnered carriers. Domestic shipments already have their own delivery-window requirements. Partnered Carrier and Amazon Global Logistics shipments are not affected in the same manual-entry way.

Is the delivery window the same as the ship date?

No. The ship date is when the shipment leaves its origin. The delivery window is the estimated seven-day range when it should arrive at Amazon’s fulfilment centre.

Can a UK buffer remove the requirement?

No. A UK buffer can reduce exposure to international replenishment delays, but it does not remove your responsibility to provide an accurate delivery window for shipments that are within the policy scope.

Can EASYADD prepare stock for Amazon FBA?

Yes. EASYADD can receive stock in the UK, complete goods-in and inventory inspection, provide secure buffer storage, carry out FNSKU labelling, polybagging and carton-standard preparation, then prepare stock for onward shipment to Amazon.

EASYADD does not control Amazon receiving, guarantee Amazon arrival or automatically enter Amazon delivery windows unless a specific integrated process states otherwise.
