Every country has its own set of customs regulations, but one requirement that all countries have in common is that the clearing agent or customs broker (as they are known in a few countries) be accredited with the local customs authorities, border agencies, ports, and other authorities involved in the shipment of goods.

When clearing items on behalf of the consumer, custom clearance agents in India must have a valid clearing licence. A few countries have strict licencing requirements that are regularly reviewed, and agents who fail to meet them risk having their licences revoked.
