📘 What Is an HSN Code?

HSN (Harmonized System of Nomenclature) is a global classification system used to systematically categorize goods under tax systems like India’s Goods and Services Tax (GST).

Each product is assigned a unique 6- to 8-digit code. For seamless GI pipes, the HSN code depends on factors like:

• Seamless vs Welded

• Galvanized vs Non-galvanized

• Use case and material type
