Data sources.

HSN/SAC master

Codes and official descriptions come from the GST portal's published HSN/SAC master (services.gst.gov.in), covering 22,609 codes: 98 chapters, 1,348 headings, 5,773 subheadings, 14,709 tariff items and 681 SAC service codes.

GST rates

Goods rates come from Notification No. 9/2025-Central Tax (Rate) dated 17-09-2025 (schedules I–VII, effective 22-09-2025, superseding 1/2017) and Notification No. 10/2025-Central Tax (Rate) (nil-rated goods, superseding 2/2017), published on taxinformation.cbic.gov.in. Where a specific code has no explicit entry, the rate is inherited from its heading or falls to the residual 18% entry (Schedule II, S.No 639) — inherited rates are marked as such on code pages.

What AI does and doesn't do

AI writes the plain-English explanations and the everyday product names used by search. It never writes or edits official descriptions, rates, notification numbers or legal rules. AI-written text is review-gated before it appears publicly.

This site is compiled with care but is not tax advice. Verify classifications with your tax advisor before filing.
