If you're ready to start selling through Amazon FBA in the UK, great choice. Fulfilment by Amazon (FBA) can save you a lot of time by handling storage, packaging, and delivery for you.

Shipping through FBA can cost up to 70% less per unit compared to other premium fulfilment services. However, to get the most out of it, you need to know how to properly prepare and send your products to Amazon's UK fulfilment centres.

This step-by-step guide will walk you through everything you need to know to send products to Amazon FBA UK confidently.

Why sell through Amazon?

If you're looking to grow your product sales, Amazon is one of the best places to start. It’s the UK’s most visited e-commerce site, with over 300 million monthly visits. That’s a huge audience actively searching for products just like yours.

Selling on Amazon gives you immediate access to a trusted platform with built-in tools for marketing, customer service, and delivery. You don’t need to build a website or manage every part of the sales process yourself. Amazon handles the hard parts so you can focus on sourcing, branding, or expanding your range.

Using Fulfilment by Amazon (FBA) takes this a step further. With FBA, Amazon stores your products, packs them when someone places an order, and ships them straight to the customer. 

So, here's how to get started. 

Step 1: Create an Amazon seller account

First things first, you need a professional seller account on Amazon. If you haven't set this up yet, head over to sellercentral.amazon.co.uk and register.

Make sure to have the following ready:

• Business details (including VAT info if applicable)
• Bank account information
• Valid ID and proof of address

Once you're registered, you’ll have access to Amazon Seller Central, where everything happens.

Step 2: List your products

Next, you need to add your products to your Amazon inventory. If your products already exist on Amazon, you can match them to existing listings. If they’re new, you’ll need to create new product listings.

For each product, you'll provide:

• Title
• Description
• Images
• Price
• Product identifiers like UPC or EAN
  
  

Make sure your listings are accurate and follow Amazon's guidelines. This step is key to making sure your items are properly received and stored by Amazon.

Step 3: Convert to FBA

After your product is listed, you need to switch it from Merchant Fulfilled to Fulfilled by Amazon. To do this:

1. Go to Manage Inventory in Seller Central
   
   
2. Select the products you want to send to FBA
   
   
3. Choose Change to Fulfilled by Amazon

This tells Amazon you'll be sending your stock to their warehouses for them to handle the fulfilment.

Step 4: Create a shipping plan

Now it’s time to create a shipping plan. Amazon uses this to direct your goods to the correct fulfilment centre.

1. Go to Inventory > Manage FBA Shipments
   
   
2. Click Send to Amazon
   
   
3. Select your products and the quantity you want to send
   
   
4. Choose your packaging type: individual units or case-packed (all units in a box are the same product)

Amazon will then tell you where to send your items. You may need to ship to more than one fulfilment centre depending on what you're sending.

Step 5: Prepare and label your products

Amazon has strict requirements for packaging and labelling, so make sure to follow them carefully. Here’s what you’ll typically need:

• Packaging: Items must be safely packaged to prevent damage. Use poly bags, bubble wrap, or boxes depending on the product.
  
  
• Labelling: Every unit must have a scannable FNSKU barcode (Amazon's unique product label). You can print these from Seller Central.

You can label products yourself or pay Amazon to do it (for a per-item fee).

Step 6: Ship your products

Once everything is packed and labelled, it's time to ship.

• Choose a carrier: You can use Amazon’s partnered carriers (usually UPS) or arrange your own.
  
  
• Print your shipment labels: Amazon will generate shipping labels for each box. Print and attach them securely.
  
  
• Book the shipment: Arrange collection or drop-off with your chosen courier.
  
  

If you're shipping from outside the UK, make sure to sort out customs paperwork. You’ll also need to have your products cleared through UK customs and possibly register for VAT.

Step 7: Track and confirm delivery

After sending, you can track your shipment in Seller Central under Shipments. Once your stock arrives at the fulfilment centre, Amazon will check everything in, and your listings will go live as FBA offers.

Depending on the delivery and how busy Amazon is, this could take a few days to a week.

Bonus tips

• Start small: If you’re new to FBA, test with a small batch to get the hang of it before scaling.
  
  
• Keep good records: Stay on top of your stock levels, shipping invoices, and VAT filings (especially if you import).
  
  
• Stay compliant: Double-check that your products meet UK regulations, especially for categories like food, cosmetics, or electronics.
