At the customs border, declaration requirements, duty obligations, and inspection procedures take effect: it marks the perimeter of a state's or customs union's customs territory, beyond which goods, vehicles, and persons fall under customs law. The customs border does not necessarily coincide with a country's political frontier. Within the EU, internal customs borders between member states have been abolished, replaced by a single external border facing third countries. For freight forwarders and customs brokers, precise knowledge of procedural requirements at each crossing point is essential to avoid costly delays and penalties. The customs border is the boundary line – distinct from the customs territory, which is the space it encloses.
