Boron-10 Enriched Boric Acid from Japan
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.

Import Tips
• Obtain NRC or DOE export/import licenses due to nuclear material status; verify isotopic enrichment certificates from suppliers
• Include radiation safety data sheets and ensure packaging meets UN hazardous material standards for transport
• Avoid misclassification as regular boric acid (2810.00); confirm boron-10 content exceeds natural abundance via lab analysis
