Customs agents exist to provide a professional service between HM Customs & Excise and the trade, i.e. importers/exporters. Agents understand the laws applicable, the services and regulations which govern imports and exports within the EU and therefore are best placed to assist. Representations can be made without the need for an agent however it is strongly advised that you should seek to appoint one due to the complexity of the system and even the most basic knowledge required to navigate the government systems.
