This is an indicative seal that a customs officer may apply to identify goods under customs control. It may be applied in addition to a trader’s commercial seal. If, in the UK, you receive goods secured by an official customs seal you must inform your local HMRC control office as soon as they arrive. Unless you’re an authorised consignee you must not remove an official seal without prior approval from customs. Interference with, or unauthorised breakage or removal of, an official seal is an offence under Customs and EU law. It’s important therefore that you’re able to recognise these seals.
