Products classified under HTS 2845.20.00.00
Boron-10 Enriched Boric Acid
Boric acid (H3BO3) where the boron isotope is enriched in boron-10, typically to over 90% isotopic purity, used in nuclear reactor control rods and neutron detection. It falls under HTS 2845.20.00.00 as a compound of boron enriched in boron-10, distinct from natural isotopic mixtures. This chemically defined compound meets Chapter 28 criteria for isotopic enrichment.
Sodium Borohydride-10 Enriched
NaBH4 with boron-10 enrichment, a reducing agent for specialized chemical synthesis and neutron-sensitive applications. Falls under HTS 2845.20.00.00 as a compound of enriched boron isotope, meeting Chapter 28 criteria for chemically defined compounds. Supplied in stabilized powder form.
Trimethyl Borate-10 Enriched
B(OCH3)3 liquid with boron-10 enrichment, a reagent in organic synthesis and isotopic labeling studies. Under HTS 2845.20.00.00 as an organic compound of enriched boron, per Chapter 28 and 29 note cross-references. Highly flammable, distilled purity.
Boron-10 Enriched Boron Oxide Powder
B2O3 powder with boron enriched in the boron-10 isotope, used in specialized glass manufacturing and neutron shielding. Classified under HTS 2845.20.00.00 because it is a compound of isotopically enriched boron per Chapter 28 notes on isotopes. Purity levels are documented for nuclear and research applications.
Decaborane-10 (B10H14) Isotopically Enriched
Decaborane enriched with boron-10, a volatile boron hydride used in rocket propellants and boron neutron capture therapy precursors. It qualifies for HTS 2845.20.00.00 as an organic compound of boron-10 enriched isotope, per Chapter 28 definitions. Handled under strict safety protocols due to reactivity.
Boron-10 Enriched Boron Nitride Powder
BN powder with high boron-10 content, used in high-temperature ceramics and neutron detectors. Classified in HTS 2845.20.00.00 as an inorganic compound of isotopically enriched boron. Differs from standard BN by isotopic specification per Chapter notes.
