HS Code 2850Hydrides, nitrides, azides, silicides and borides, whether or not chemically defined, other than compounds which are also carbides of heading no. 2849
1 six-digit code · Heading 48 of 50 in Chapter 28 · World Customs Organization Harmonized System
HS code 2850 is the customs home for metal hydrides, nitrides, azides, silicides and boride powders. Read on to see what fits, what does not, and how to find the companies that trade them.
Heading 2850does not subdivide further in the WCO nomenclature: goods answering to “Hydrides, nitrides, azides, silicides and borides, whether or not chemically defined, other than compounds which are also carbides of heading no. 2849” classify at the single six-digit code 285000. The heading is number 48 of 50 in Chapter 28, Inorganic chemicals; organic and inorganic compounds of precious metals; of rare earth metals, of radio-active elements and of isotopes, which runs to 180 six-digit codes in all.
Six-digit codes under heading 2850
| HS Code | Import–export description |
|---|---|
| 285000 | Hydrides, nitrides, azides, silicides and borides, whether or not chemically defined, other than compounds which are also carbides of heading no. 2849 |
What HS code 2850 covers
These goods are inorganic compounds. Each one joins an element to hydrogen, nitrogen, silicon or boron, or it is an azide. Think of metal hydrides, nitride ceramics, silicide powders and boride powders.
The wording also says the compound may or may not be chemically defined. So a pure lab-grade material and a commercial blend can both belong here.
There is one big exception. A compound that is also a carbide is not classified here. It moves to heading 2849. Customs officers check this first.
Plain gases and basic elements usually sit elsewhere. Hydrogen, for example, is a non-metal and belongs with heading 2804.
Code 285000 and the HSN code 2850
Many traders search for the HSN code 2850 or the HTS code for this heading. These are not new systems. They are national versions built on the same international base. The first six digits stay the same in every country. A country may then add its own digits for local tariff and statistics needs.
So start with 285000 when you fill in a shipping document or check a tariff. After that, look up the longer national code in the tariff of the country you ship to or from.
Duty rates are set by each country and can change. This page lists none. Check the official tariff of your market. If you are unsure which code fits your goods, try the HS code classifier.
Difference between HS 2850 and 2849 carbides
The most common mistake is mixing up 2850 and 2849. A carbide goes to 2849, even when it looks a lot like a boride or a nitride. When in doubt, check the chemical formula first.
Two more nearby headings are easy to confuse with this one:
- 2849 holds carbides.
- 2852 holds compounds of mercury, but not amalgams.
- 2853 holds phosphides (not ferrophosphorus) and other inorganic compounds not named elsewhere.
HS code for metal hydrides, nitride compounds and boride powder
People often search by product name, not by code. The heading names these compound types directly, so the match is simple.
A metal hydride is a hydride. A nitride compound is a nitride. Boride powder is a boride. Silicides and azides follow the same logic. All of them use 285000.
If your product is a mix of several things, a customs broker or your national customs office can confirm the final code before you ship.

HS Code 2850: common questions
What does heading 2850 cover?
It covers a group of inorganic compounds in Chapter 28. They are made with hydrogen, nitrogen, silicon or boron, plus azides.
What is the six-digit HS code for hydrides and borides?
Use 285000. It is the only six-digit code listed under this heading.
Are carbides classified under HS 2850?
No. Carbides have their own heading, 2849.
Is HSN code 2850 the same as the HS heading?
They share the same base. HSN and HTS codes add national digits after the six-digit code 285000.
Where are phosphides classified if not in 2850?
Look in heading 2853. It also takes other inorganic compounds not named elsewhere.
Who imports hydrides and borides?
Companies that file customs records under this heading. You can look them up through the import data and buyer data pages on EximDataX.
