A declaration by conduct is when you transport your goods through a customs control point (usually a green channel marked ‘nothing to declare’) at a port (including roll on roll off locations) or airport. You do not need to stop or speak to a customs officer, you can simply:

• walk through a customs control point with the goods
• drive past a customs control point with the goods inside your vehicle
• continue your onward journey if there are no customs control points (this is still deemed to be a declaration by conduct)

An oral declaration can be made by passing through a red channel (or using a red phone, where available) at a port or airport, and verbally telling a customs officer:

• what the goods are
• what the purpose of the goods is
• who you’re making this declaration for (yourself or on behalf of someone else)
