HSN/SAC codes below are sourced from the official GST Portal classification master. GST rates are maintained separately and are shown as verified only where independently confirmed from official Government sources. For other codes, always verify the latest applicable GST notification, including any conditions, exemptions or special rates. This is a reference tool, not legal or tax advice.
GST Rate Sources & Methodology
Scroll here to load the HSN/SAC reference…
Classification and GST rate are separate legal determinations. HSN/SAC classification is sourced from the official GST Portal master. Only rates explicitly marked "✓ Rate Verified" have been independently verified against an official source — unverified rates must be checked against the latest applicable GST notification before use. "⚠ Not Independently Verified" means this Knowledge Centre has NOT independently confirmed a rate for that specific code, not that no rate applies.
