Customs Consolidation Act 1876

139 In case of public emergency, &c, pre-entry of export or coastwise goods may be required.

The Commissioners of Customs may, by order under their hands, require due entry and clearance before shipment, and in such manner as they may direct, of any goods intended for exportation or carriage coastwise, on being satisfied that the public interests render such course expedient, and if upon such entry the goods shall not be found to correspond with the particulars contained therein, they may be detained until the cause be explained to the satisfaction of the Commissioners of Customs, who may thereupon restore the same on such terms as they may see fit; and any exporter and shipper of any cask or package, containing any explosives as defined by " The Explosives Act, 1875," or by any Order in Council made pursuant thereto, shall duly enter the same before shipment thereof, and in the entry outwards or coastwise thereof shall correctly describe such explosive according to such definition; and if he shall fail or neglect to make such entry, or if the same be false in any particular, he shall forfeit the sum of one hundred pounds, and such cask or package, and the contents thereof, shall also be forfeited.
