Contraband

Goods that a belligerent may lawfully seize when bound for an enemy, under the prize law of naval warfare. The 1909 Declaration of London distinguished absolute contraband (arms and war materiel) from conditional contraband (dual-use goods such as fuel and food serving military ends), though that treaty never entered force. A capturing warship diverts the cargo to a prize court for condemnation. In sanctions usage the word loosely covers any goods carried in breach of an embargo or trade prohibition.
