HS Code for Isotope separators

Isotope separators are complex mechanical and electrical systems designed to segregate different isotopes of the same chemical element based on their physical properties, such as mass or ionization potential. These machines are classified under HS code 8401.20. Chapter 84 generally covers machinery and mechanical appliances, but heading 8401 is specifically reserved for nuclear reactors, fuel elements, and machinery for isotopic separation. The inclusion of these separators in 8401 reflects their primary historical and industrial association with the nuclear fuel cycle, although they are also used for producing stable isotopes for medical and scientific use. The category includes various technologies such as gas centrifuges, electromagnetic separators (like calutrons), and laser-based separation units. Parts of these machines are also classified here, provided they are identifiable as being solely or principally for use with such apparatus. The classification is determined by the specific function of the machine—separating isotopes—rather than the general mechanical principles it employs.

Products Included

• Gas centrifuges for uranium enrichment
• Electromagnetic isotope separators (calutrons)
• Laser isotope separation equipment
• Thermal diffusion columns for isotopic separation

Common Misclassification

Isotope separators are sometimes misclassified under 8421, which covers general-purpose centrifuges and filtering apparatus. However, 8401.20 is the more specific code for isotopic separation. They may also be confused with 9027 if they are small-scale laboratory instruments used for analysis rather than production.

FAQ

What is the HS code for Isotope separators?
