Why this service matters
An import declaration tells HMRC what goods are entering the UK, where they came from, their value, classification and how any duties or taxes should be handled.
If the declaration is incomplete or incorrect, the result can be delays, extra costs, storage charges or compliance issues. Accurate import declarations help keep goods moving and give importers a clearer record of what has been declared to HMRC.
