HS Code for Isotope compounds
Isotope compounds are substances where the atoms of one or more elements have been replaced by specific isotopes, usually for research, medical, or industrial tracing purposes. The Harmonized System distinguishes between radioactive isotopes (Chapter 2844) and stable isotopes. Heading 2845 is dedicated to stable isotopes and their inorganic or organic compounds. Subheading 2845.90 serves as the residual category for these materials that are not specifically named in other subheadings like 2845.10 (heavy water) or 2845.20 (boron enriched in boron-10). The classification applies regardless of whether the compound is organic or inorganic, provided the isotopic enrichment is the defining characteristic. This includes compounds of carbon-13, nitrogen-15, or oxygen-18. These materials are vital in NMR spectroscopy and metabolic studies. The classification logic follows the principle that isotopic modification changes the fundamental nature of the chemical for trade purposes, moving it from its standard heading in Chapter 28 or 29 to the specialized isotope heading.
Products Included
- Carbon-13 labeled organic compounds
- Nitrogen-15 enriched salts
- Oxygen-18 labeled water (non-radioactive)
- Deuterated solvents (other than heavy water)
Common Misclassification
The most common error is classifying these under HS code 2844, which is strictly for radioactive isotopes. Stable isotopes must stay in 2845. Additionally, heavy water is often incorrectly placed in 2845.90, but it has its own specific code, 2845.10.

Frequently Asked Questions
What is the HS code for Isotope compounds?
The HS code for Isotope compounds is 284590 (Isotopes other than those of heading no. 2844, 2845.20, 2845.30 or 2845.40; compounds, inorganic or organic, of such isotopes, whether or not chemically defined).
How do I classify Isotope compounds for customs?
Isotope compounds is classified under HS code 284590 — Isotopes other than those of heading no. 2844, 2845.20, 2845.30 or 2845.40; compounds, inorganic or organic, of such isotopes, whether or not chemically defined. This is a 6-digit subheading level code.
Is the HS code for Isotope compounds the same in all countries?
The base HS code 284590 for Isotope compounds is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
