HSN codes for industrial chemicals

HSN stands for Harmonized System of Nomenclature, the international product-classification system. Each product gets a numeric code that customs authorities and tax systems use to identify it.

ITC(HS) is India's import and export classification, published by DGFT. It follows the international system for the first 6 digits and adds its own digits to reach 8. The 8-digit code is what this page calls the HSN.

The international system has 6 digits. India's customs tariff uses 8, and these 8-digit codes are what you will see on import documents. The number of digits to show on a tax invoice depends on the supplier's circumstances, so confirm with your tax adviser.

Most industrial chemicals are in Chapters 28 and 29 (inorganic and organic chemicals). Some products, such as industrial fatty acids, fall in Chapter 38, and resins and polymers are in Chapter 39. The chapter alone does not give the full code, so the exact heading and item matter.

The tariff lists individual substances. For example, propan-1-ol and isopropyl alcohol are both propyl alcohols but sit on separate lines that differ in the last digits. Choose the line that names the substance, not just the family.

It can. A liquid solution and a solid of the same compound may sit on different lines. Grade does not always change the line: in the table above, two glycerol grades share one code. Classify by the exact product that is actually shipped.

Start with the ITC(HS) schedule on the DGFT website and the customs tariff. The schedule is organised by chemical name, and CAS numbers are generally not listed in it, so search by name. Your customs house agent or tax adviser confirms the final code.

Treat it as a reference. The classification you declare is ultimately your own responsibility, so verify it against the schedule for your product and your use.

A wrong code can lead to delays at clearance, queries from the authorities and mismatches in tax records. This is why it is worth confirming the code before ordering.

No. A CAS number identifies a specific chemical substance worldwide. An HSN code classifies a product for tariff and tax purposes. They are different systems, and one HSN line can cover several CAS numbers.

No. It lists classification only. Rates change and depend on origin, notifications and your own situation, so check the current position with your customs or tax adviser.
