Isotopes other than those of heading 2844; compounds, inorganic or organic, of such isotopes, whether or not chemically defined
5 declarable lines
Heading 2845 covers isotopes other than those covered by heading 2844, and inorganic or organic compounds of those isotopes, whether or not chemically defined. It has specific lines for heavy water, boron enriched in boron-10, lithium enriched in lithium-6, and helium-3, plus an other line. All listed lines carry a general (MFN) rate of Free.
Products in this heading
- Heavy water (deuterium oxide)
- Boron enriched in boron-10
- Compounds of boron enriched in boron-10
- Lithium enriched in lithium-6
- Compounds of lithium enriched in lithium-6
- Helium-3
- Stable isotopes not named in the specific lines
- Compounds of stable isotopes not named in the specific lines
How to choose the right subheading
- Identify the isotope: deuterium, boron-10, lithium-6, helium-3, or another isotope.
- Decide whether the product is the isotope itself or an inorganic or organic compound of that isotope.
- Check that the product is not radioactive; radioactive isotopes are outside this heading.
- Match heavy water to 2845.10.00.00, boron-10 to 2845.20.00.00, lithium-6 to 2845.30.00.00, and helium-3 to 2845.40.00.00.
- Use 2845.90.01.00 for other isotopes and their compounds within the heading.
Often confused with
- Heading 2844Radioactive isotopes and their compounds
Heading 2844 covers radioactive isotopes and compounds.
- Heading 2840Ordinary borates not enriched in boron-10
Borates without boron-10 enrichment are classified in heading 2840.
- Heading 2846Compounds of rare-earth metals
Rare-earth compounds are covered by heading 2846, not by the isotope lines.
- Heading 2853Distilled or conductivity water
Water of that purity is named in heading 2853.
- Heading 2852Mercury compounds
Mercury compounds have their own heading.
Frequently asked questions
What is the HTS code for heavy water?
Heavy water (deuterium oxide) is classified under 2845.10.00.00, with a general (MFN) rate of Free.
What is the duty on boron enriched in boron-10?
Boron enriched in boron-10 is classified under 2845.20.00.00, with a general (MFN) rate of Free. Compounds of that enriched boron stay in the same subheading.
How do I classify a stable isotope product that is not heavy water, boron-10, lithium-6, or helium-3?
Use 2845.90.01.00, with a general (MFN) rate of Free, for a stable isotope or a compound of a stable isotope that is not named in the earlier subheadings.
