U.S. exports of hydrides, nitrides, azides, silicides, and related inorganic compounds (HS 285000) totaled $22.5M in July 2026.
Importers of Hydrides, Nitrides, Azides, Silicides, and Related Inorganic Compounds paid $719K in duties in July 2026 — an effective duty rate of 23% on $3.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataTitanium nitride, tungsten hydride, vanadium nitride, and calcium hydride are representative materials in this technically diverse heading, which supplies the advanced ceramics, hard coatings, pyrotechnics, and specialty metallurgy sectors. The US schedule carves out specific 10-digit lines for calcium (2850000500), titanium (2850000700), tungsten (2850001000), and vanadium (2850002000) hydrides and nitrides, with a catch-all line (2850005000) for remaining compounds. Germany and Japan are the leading suppliers, reflecting their strength in specialty inorganic chemistry and advanced materials manufacturing. Classification at the 10-digit level requires precise chemical identification, as the heading spans compounds with very different physical properties and end uses.

HTS 285000 covers titanium nitride as a chemical substance or powder (2850000700). Titanium nitride applied as a physical vapor deposition coating on a finished tool is not separately classified — the coated article is classified by its essential character as a tool. Only the uncoated powder or bulk compound falls under this heading.
Certain tungsten compounds can be subject to dual-use export controls in the country of origin, and US importers should verify whether the supplier's export license is required. While US import classification under HTS 285000 is straightforward, downstream re-export of tungsten-based materials may trigger EAR (Export Administration Regulations) review depending on end use and destination.
