Nuclear reactors; fuel elements (cartridges), non-irradiated, for nuclear reactors; machinery and apparatus for isotopic separation; parts thereof
4 declarable lines
Heading 8401 covers nuclear reactors, machinery and apparatus for isotopic separation, non-irradiated fuel elements (cartridges), and parts of these goods. It splits into four lines: complete reactors, isotopic separation machinery and its parts, fuel elements and their parts, and parts of reactors. Irradiated fuel elements are not classified here.
Products in this heading
- Complete nuclear reactor unit for power generation
- Gas centrifuge used for uranium isotopic separation
- Non-irradiated uranium fuel assemblies for a reactor
- Non-irradiated fuel cartridges for a research reactor
- Parts of an isotopic separation apparatus, such as its rotor assemblies
- Reactor pressure vessel internals classified as parts of nuclear reactors
- Control rod drive mechanisms entered as parts of nuclear reactors
How to choose the right subheading
- Decide whether the item is a complete reactor, an isotopic separation machine, a fuel element, or a part.
- For fuel elements, confirm the goods are non-irradiated; irradiated fuel is outside this heading.
- For parts, identify whether the part belongs to a reactor (8401.40) or to isotopic separation machinery (8401.20).
- Check that the item is not a separate machine named in another heading, such as a turbine, boiler, pump or centrifuge.
Often confused with
- Heading 8406Steam turbine driving a reactor's generator
Turbines are classified in their own heading, even when installed in a nuclear plant.
- Heading 8402Steam generating boiler for a nuclear plant
Vapor generating boilers and their parts belong to heading 8402.
- Heading 8421Centrifuge not intended for isotopic separation
General purpose centrifuges and centrifugal dryers are in heading 8421.
- Irradiated (spent) fuel elements
Heading 8401 covers only non-irradiated fuel elements; spent fuel is classified elsewhere.
- Heading 8417Industrial furnace or oven used in fuel processing
Non-electric industrial or laboratory furnaces and ovens are in heading 8417.
Frequently asked questions
What is the HTS code for a nuclear reactor?
Complete nuclear reactors are classified under 8401.10.00.00, with a general (MFN) duty rate of 3.3%.
What is the duty on machinery for isotopic separation?
Machinery and apparatus for isotopic separation, and parts thereof, fall under 8401.20.00.00 at a general (MFN) rate of 2.6%.
How do I classify non-irradiated fuel elements?
Non-irradiated fuel elements (cartridges) and their parts are classified under 8401.30.00.00 at a general (MFN) rate of 3.3%. Parts of nuclear reactors themselves go under 8401.40.00.00, also at 3.3%.
