UKIMS Numbers for Windsor Framework

This section explains UKIMS numbers and UK Government guidelines "at risk" and "not at risk" goods.

What is a UKIMS number?

The UK Internal Market Scheme (UKIMS) number allows shippers, and recipients, to declare goods as being “not at risk” if they are shipped from GB to NI for sale or final use by end consumers in NI.

UK Government Guidelines for “Not at Risk” Goods

The UK government guidelines advise that “not at risk” goods will:

  • not be charged duty if entering Northern Ireland (NI) from free circulation in Great Britain (GB)

  • be charged UK duty if entering NI from outside the EU and the UK

  • be charged UK duty if entering NI from GB and the goods were not in free circulation in GB.

‘At risk’ goods will be charged the applicable EU rate of duty.

For more information on applying for authorisation for the UK internal market scheme, please refer to:

ShipStation recommends that you always provide at least one UKIMS number (and corresponding EORI number) for B2B shipments. We also recommended that you provide the EORI number for each UKIMS number (shipper/recipient) provided.

See ShipStation's guidance on Tax Identification Numbers.

ShipStation will not validate that UKIMS / EORI numbers have been provided unless the carrier instructs us to do so. Carriers that ShipStation integrates with via API may apply data validation. This validation is outside ShipStation’s control.
