HS code for Boron-10 enriched compounds: 2845.20
Boron enriched in boron-10 and its compounds.
Classification of boron-10 enriched compounds under HS 2845.20
Boron-10 enriched compounds are classified under Harmonized System (HS) code 284520. This specific classification falls within Chapter 28, which covers inorganic chemicals, and more precisely under Heading 2845, dedicated to isotopes and their compounds, other than those of Heading 2844. The subheading 284520 is explicitly defined as "Boron enriched in boron-10 and its compounds." This code applies to any form of boron where the natural isotopic abundance of boron-10 has been artificially increased, as well as any chemical compounds derived from such isotopically enriched boron. The critical factor for this classification is the enrichment of the boron-10 isotope, which imparts specific properties and applications, particularly in nuclear technology and medicine.
- Covers
- Boron-10 enriched boric acid
- Boron-10 enriched boron carbide
- Boron-10 enriched boron trifluoride
- Boron-10 enriched elemental boron (if the enrichment process results in an elemental form)
- Other chemical compounds containing boron with an artificially increased concentration of the boron-10 isotope
- Also under 2845.20
- 3M (boron-10 products)
- EaglePicher Technologies
- various nuclear material suppliers.
Codes often confused with 2845.20
Common mistake. A common misclassification for boron-10 enriched compounds is with HS code 280450, which covers "Boron; tellurium." This code is intended for elemental boron in its natural isotopic abundance, not for isotopically enriched forms or their compounds. The distinction lies in the isotopic modification. Another potential area of confusion is with 284590, "Other isotopes and their compounds; mixtures of isotopes or compounds of this heading," which is a residual category for other isotopes. However, since 284520 specifically identifies boron-10 enriched materials, it is the precise and correct classification for these specialized products.
Top exporters and importers of HS 284520 (the code used for boron-10 enriched compounds), 2025
In 2025, the largest exporter of HS 284520 (the code used for boron-10 enriched compounds) in UN Comtrade data was Japan, with 74% of world exports; the largest importer in UN Comtrade data was China, with 75% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about boron-10 enriched compounds
What is the HS code for Boron-10 enriched compounds?
The HS code for Boron-10 enriched compounds is 284520 (Boron enriched in boron-10 and its compounds). The HS code for boron-10 enriched compounds, including boron enriched in boron-10 and its chemical derivatives, is 284520.
How do I classify Boron-10 enriched compounds for customs?
Boron-10 enriched compounds is classified under HS code 284520 — Boron enriched in boron-10 and its compounds. This is a 6-digit subheading level code.
Why is boron-10 enrichment significant for HS classification?
Boron-10 enrichment is significant because it alters the nuclear properties of boron, making it valuable for specific applications such as neutron absorption in nuclear reactors, radiation shielding, and certain medical therapies. The HS classification system recognizes this distinct characteristic by providing a dedicated subheading (284520) to differentiate these specialized materials from naturally occurring or unenriched boron.
Which countries are the top exporters of boron-10 enriched compounds (HS 284520)?
In 2025, the top exporters of HS 284520 (the code used for boron-10 enriched compounds) in UN Comtrade data were Japan ($16M, 74% of world exports), the United States ($4.8M) and China ($585K). World exports came to about $22M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of boron-10 enriched compounds (HS 284520)?
In 2025, the top importers of HS 284520 (the code used for boron-10 enriched compounds) in UN Comtrade data were China ($14M, 75% of world imports), France ($1.3M) and Georgia ($1.2M). World imports came to about $18M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
