HS Code 2850
Hydrides, Nitrides and Borides
HS code 2850 covers inorganic hydrides, nitrides, azides, silicides, and borides used in high-tech manufacturing, ceramics, and electronics sectors worldwide.
HS Code 2850 — Hydrides, Nitrides and Borides
This category includes compounds of hydrogen, nitrogen, silicon, or boron with other elements, excluding carbides. These chemicals are vital for semiconductor manufacturing, aerospace components, and advanced ceramics due to their specialized electrical and thermal properties.
What's included
- Titanium nitride
- Sodium azide
- Silicon nitride
- Calcium hydride
- Aluminium boride
What's excluded
- Ammonia → use
2814(Classified under its own specific heading for nitrogen compounds.) - Thorium nitride → use
2844(Radioactive chemical elements and compounds take precedence.)
Common examples
- Sodium azide for airbag inflators
- Titanium nitride gold-coloured coating
- Magnesium silicide for alloy production
- Lithium aluminium hydride
Frequently asked questions
How is sodium azide classified for shipping?
Sodium azide is a toxic substance (Class 6.1) and requires rigorous dangerous goods documentation and specialized packaging.
