U.S. exports of boron & tellurium (HS 280450) totaled $1.9M in July 2026.
Importers of Boron & Tellurium paid $47K in duties in July 2026 — an effective duty rate of 26% on $177K in dutiable value, based on actual customs collections rather than the published tariff schedule. Boron & Tellurium imports of $808K in July 2026 ran 67% above the year-to-date monthly average of $483K.
Last updated: July 2026 dataBoron and tellurium are classified together under heading 280450 but serve sharply different industrial purposes: boron is a key input for specialty glass, ceramics, and nuclear shielding, while tellurium is a critical material in thin-film photovoltaic cells and thermoelectric devices. The US schedule separates them at the 10-digit level — boron under 2804500010 and tellurium under 2804500020 — making correct classification essential for accurate duty and trade-remedy exposure assessment. Germany and Canada are the leading suppliers, though China also appears in the supply mix, raising supply-chain concentration considerations for tellurium given its critical-mineral status. Importers sourcing tellurium in particular should monitor any Section 301 exposure on Chinese-origin goods.

Classification depends on the chemical identity of the element: boron (atomic number 5) enters under 2804500010, while tellurium (atomic number 52) enters under 2804500020. Mixed or compound forms may fall outside heading 280450 entirely and require separate classification analysis.
Yes. The US government has designated tellurium as a critical mineral due to its concentrated global supply and its essential role in cadmium telluride (CdTe) thin-film solar panels and thermoelectric applications. Importers should track any trade-remedy or export-control developments affecting primary supplier countries.
