Nuclear reactors imported under this heading are subject to stringent US Nuclear Regulatory Commission (NRC) licensing requirements, making them among the most tightly controlled capital goods in international trade. The single US tariff line (8401100000) captures complete reactor units, which are rarely traded as finished imports but may appear in transactions involving research reactors or modular designs. Classification questions often hinge on whether a shipment constitutes a complete reactor versus discrete components, which fall under separate headings for parts or fuel elements.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. The US Nuclear Regulatory Commission requires import licenses or authorizations for nuclear reactors and associated nuclear materials. Customs entry alone is insufficient; importers must coordinate NRC licensing well in advance of shipment.
A complete or assembled reactor classifies under 8401100000, while discrete structural or mechanical components that do not constitute a complete reactor are classified under heading 840140 (parts of nuclear reactors). The distinction turns on whether the shipment is functional as a reactor unit or serves only as a component thereof.
