Step 1 Get a UK EORI number for your business
Your business will already 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.
Step 2 Decide who will make the customs declarations
Contact the organisation that brings your goods into 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.
Step 3 Apply to make importing easier
Step 4 Find out what you'll have to pay to import your goods
Step 5 Check what you need to do for the type of goods you import
Depending on what you're importing, 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.
