Prohibits public entities from using foreign-made small, unmanned aircraft systems.

S 3483 bans New Jersey state and local government agencies (including counties, municipalities, and public authorities) from using small drones where over 25% of the components are made in foreign countries. The bill defines "foreign-made" as drones with foreign parts costing more than a quarter of the total component cost, and "foreign country" to include all nations outside the U.S. and their territories. It applies to all public entities using drones weighing under 55 pounds for any purpose. The law takes effect six months after enactment, allowing agencies time to adjust their drone procurement.
