U.S. imports of boron enriched in boron-10 and its compounds (HS 284520) totaled $3K in June 2026, traded with 1 country.
Boron Enriched in Boron-10 and Its Compounds imports of $3K in June 2026 ran 500% above the year-to-date monthly average of $557.5.
Boron enriched in the boron-10 isotope is a critical neutron-absorbing material used in nuclear reactor control rods, radiation shielding, and neutron detection instruments. Natural boron contains roughly 20% boron-10, so isotopic enrichment — typically via chemical exchange or laser separation — is required to reach the concentrations demanded by reactor and detector applications. Because enriched boron-10 is a dual-use nuclear material, US imports under tariff line 2845200000 are subject to NRC licensing requirements and may also fall under export control review by the country of origin. Importers should confirm whether the specific compound form (elemental boron, boric acid, boron carbide, or other) affects classification at the 10-digit level.

Heading 284520 applies specifically to boron that has been artificially enriched in the boron-10 isotope beyond its natural abundance, as well as compounds of such enriched boron. Naturally occurring boron and its compounds are classified elsewhere in Chapter 28. The enrichment level itself does not create sub-classifications at the 10-digit level under 2845200000, but it is a key commercial and regulatory specification.
The primary end uses are nuclear reactor control and shutdown systems (where boron-10's high neutron-capture cross-section is essential), neutron detectors used in homeland security and research, and boron neutron capture therapy (BNCT) in medical oncology. Defense and national laboratory procurement also accounts for a portion of demand.
