HS Code 2837Cyanides, cyanide oxides and complex cyanides

What HS code 2837 covers

Cyanides are salts that contain the cyanide group. Customs uses heading 2837 to classify them, whether they are sold as a simple salt or as a more complex one. This is the heading that matters for cyanide trade within Chapter 28 inorganic chemicals.

Some countries call it HSN code 2837 and others call it HTS code 2837. The first six digits are the same in every country that uses the Harmonized System.

Six-digit codes under 2837: sodium cyanide, other cyanides, complex cyanides

The heading splits into three codes. Here is what each one means in plain words.

• 283711 is sodium cyanide. The cyanide salt must be of sodium.
• 283719 is for cyanides other than sodium cyanide. It is the catch-all for simple cyanides with a different metal or cation.
• 283720 is for complex cyanides. These are salts where the cyanide is bound inside a larger metal group.

How to choose between 283711, 283719 and 283720

Start with the chemical name on the invoice or the safety data sheet. Then ask three questions in order.

First, is it a complex cyanide? If the product is a complex salt, such as potassium ferricyanide, the heading wording points to 283720. Check this against your national tariff before you file.

Second, if it is a simple cyanide, is the metal sodium? If yes, use 283711. This is the code people search for when they look up sodium cyanide.

Third, if it is a simple cyanide of any other metal or cation, use 283719.

National tariff lines extend these six-digit codes with extra digits. Your customs broker or the HS code classifier can help you find the exact local line.

Related headings and exclusions

Not every chemical with cyanide in its name belongs here. Compounds of mercury have their own heading, 2852. Check it if your product contains mercury.

Other salts of simple inorganic acids sit nearby. Carbonates are in heading 2836. Silicates are in heading 2839. Salts of inorganic acids that are not named elsewhere go to heading 2842.

If you cannot tell which heading fits, run the product through the HS code classifier. You can also browse all HS code chapters to see how the system is organised.
