HTS US: 2845.XX.XXXX
Description
This heading encompasses isotopes other than those classified under heading 2844, along with their compounds whether inorganic or organic and chemically defined or not. These materials are critical in scientific, industrial, and medical applications due to their unique nuclear properties.
- Heavy Water (Deuterium oxide): Water in which the hydrogen atoms are replaced with deuterium, a heavier isotope of hydrogen. It is widely used as a neutron moderator in nuclear reactors.
- Boron enriched in Boron-10 and its compounds: Boron materials with an increased concentration of the isotope boron-10, important for neutron absorption in nuclear reactors and radiation shielding.
- Lithium enriched in Lithium-6 and its compounds: Lithium substances enriched with the isotope lithium-6, utilized in nuclear fusion, isotope separation, and radiation detection.
- Helium-3: A rare isotope of helium used in cryogenics, neutron detection, and medical imaging technologies.
- Other isotopes and compounds: This includes any other isotopes and their inorganic or organic compounds not specifically listed above.
Code Hierarchy
- Section VI: Products of the Chemical or Allied Industries (Chapters 28-38)
- Chapter 28: Inorganic Chemicals; Organic or Inorganic Compounds of Precious Metals, of Rare-Earth Metals, of Radioactive Elements or of Isotopes
- Heading 2845: Isotopes other than those of heading 2844; compounds, inorganic or organic, of such isotopes, whether or not chemically defined
- US HTS Code (10-digit):
2845.XX.XXXX– The final digits specify the particular isotope or compound.
Detailed Breakdown of Subheadings
The 6-digit heading 2845 is subdivided into specific 8-digit and 10-digit codes for precise classification of isotopes and their compounds:
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2845.10.00.00 | Heavy water (Deuterium oxide) | Used primarily as a moderator and coolant in nuclear reactors; chemically similar to water but contains deuterium. |
| 2845.20.00.00 | Boron enriched in boron-10 and its compounds | Materials with an increased proportion of boron-10 isotope, vital for neutron capture in nuclear technology. |
| 2845.30.00.00 | Lithium enriched in lithium-6 and its compounds | Used in nuclear fusion research, isotope separation, and radiation shielding applications. |
| 2845.40.00.00 | Helium-3 | Rare helium isotope employed in cryogenics, neutron detection, and medical imaging technologies. |
| 2845.90.01.00 | Other isotopes and their compounds | Includes any other isotopes not specified above and their inorganic or organic compounds regardless of chemical definition. |
What is NOT Classified Here?
To ensure correct classification, note these exclusions:
- Isotopes of heading 2844: These include radioactive isotopes and their compounds, which are classified separately under heading 2844.
- Pure elements without isotopic enrichment: Elements not specifically enriched in isotopes are generally classified under other headings.
- Compounds not related to isotopes: Regular inorganic or organic compounds without isotopic enrichment are excluded.
Notes
- Regulatory Controls: Many isotopes and enriched compounds are subject to strict international and national regulations due to their potential use in nuclear technology and security concerns.
- Tariff Rates: Duty rates vary depending on the specific isotope or compound and its intended industrial or scientific use.
- Special Handling: Some isotopes require specialized packaging and handling due to their physical or chemical properties.
