HS Code for Boron

Elemental boron is classified under Harmonized System (HS) code 280450. This classification is rooted in Chapter 28 of the HS nomenclature, which is dedicated to inorganic chemicals, organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes. Within this chapter, Heading 2804 specifically encompasses hydrogen, rare gases, and other non-metals. The subheading 280450 is precisely designated for "Boron; tellurium," making it the definitive classification for boron in its elemental form. This code applies to boron regardless of its purity level, as long as it remains an uncombined element. The classification reflects boron's fundamental chemical identity as a non-metallic element, distinguishing it from its compounds or isotopically modified forms.

Common Misclassification

A common misclassification for elemental boron is with HS code 284520, which is designated for "Boron enriched in boron-10 and its compounds." While related, 284520 specifically covers boron that has undergone isotopic enrichment, where the proportion of the boron-10 isotope has been artificially increased, or compounds derived from such enriched boron. This is distinct from naturally occurring or unenriched elemental boron. Another potential confusion could arise with 280490, "Other non-metals," which serves as a residual category for non-metals not specifically enumerated elsewhere in Heading 2804. However, since 280450 explicitly names boron, it is the more specific and therefore correct classification for the elemental form.

FAQ

What is the HS code for Boron?

The HS code for elemental boron, in its uncombined form, is 280450. This code covers various physical forms of boron, including powder, ingots, and flakes.

How does the purity of boron affect its HS classification?

The purity level of elemental boron does not alter its classification under HS code 280450, as long as it remains uncombined elemental boron. Whether it is technical grade or high-purity boron for specialized applications, the fundamental classification remains the same. Purity specifications are typically commercial or technical distinctions, not classification criteria within this HS code.
