  1. Step 1 Check if your business has a UK EORI number

    Your business will have a UK Economic Operator Registration and Identification (EORI) number if you’ve traded with countries outside the EU. UK EORI numbers start with GB.

    You'll need to get a UK EORI number if you do not have one.

    1. Get a UK EORI number
  2. Step 2 Decide who will make the customs declarations

    Contact the organisation that transports your goods out of the country to find out if they can make customs declarations for your goods.

    If they cannot, you can either hire an agent to make the declarations, or make the declarations yourself.

    1. Find out how to make customs declarations yourself
    2. Find out how to hire an agent to make customs declarations for you
  3. Step 3 Apply to make exporting easier

  4. Step 4 Check what your customers will need to pay

  5. Step 5 Check what you need to do for the type of goods you export

    Depending on what you're exporting, there might be other things you'll need to do to get your business ready. For example, you might need to change the labelling on the packaging for your goods, or apply for licences.

    1. Check if you'll need to apply for an export licence
    2. Check what else you need to do for the type of goods you export
