Section 6

The provisions of orders shall, unless the contrary is expressly stated, be deemed to be additional to, and not in substitution for, the provisions of any other law for the time being in force.

For the avoidance of doubt it is hereby declared that the taking into or out of Singapore of ships or aircraft or vehicles may be prohibited or regulated by an order as an importation or exportation of goods, notwithstanding that the ships, aircraft or vehicles are conveying goods or passengers, and whether or not they are moving under their own power.[7
