Nuclear Reactor Pressure Vessel
A massive cylindrical steel vessel designed to contain the reactor core, coolant, and heat generated during nuclear fission in a pressurized water reactor (PWR). It falls under HTS 8401.40.00.00 as a critical structural part of nuclear reactors, essential for maintaining high-pressure conditions and safety containment.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not nuclear-rated or lacks reactor-specific features
Standard pressure vessels without nuclear safety certifications fall under tanks and reservoirs of iron/steel.
If imported as parts of heat exchangers rather than reactors
Heat exchanger components not integral to nuclear core containment classify under machinery for heat treatment.
If for research reactors or classified as isotopic separation apparatus
Machinery for isotopic separation or non-power research equipment may shift to other nuclear machinery headings.

Import Tips & Compliance
• Obtain IAEA safeguards approval and nuclear export licenses prior to import; verify end-user certificates
• Comply with ASME Section III nuclear codes for pressure vessels; provide material traceability documentation
• Avoid misclassification as general steel tanks (HTS 7309); specify nuclear-rated design and testing
