HSN Data Sources & Methodology
Understand the information behind the HSN finder and directory.
Source and edition
Descriptions and reported IGST and compensation cess values come from hsnlookup.in, dated 24 April 2026, attributed under CC BY 4.0. ILeven normalizes spacing and adds browsing, publication decisions and explanatory interface text. Data version: hsnlookup-2026-04-24-v1.
Classification navigation
The full finder contains 14,416 eight-digit records. Parent groups follow two-, four- and six-digit prefixes. Group descriptions are derived from shared wording in the supplied records; they are not independently sourced official heading names. Chapter titles come from the WCO 2022 nomenclature. Selected heading labels are sourced separately or shown as neutral HSN headings; the original eight-digit descriptions are unchanged. Product categories are deliberately mapped browsing scopes, not new official classifications.
GST information and effective dates
The finder’s expandable source details retain the source’s unverified IGST and cess values; they are not promoted as an answer or displayed as current tax treatment on SEO pages. CGST and SGST are not derived. Values have not been independently verified against current official schedules. The supplied file does not include applicable notifications, effective dates, exemption conditions or transaction-specific treatment. A zero value is not proof of exemption.
Confirm classification, rates and conditions against the applicable official material before invoicing. Official starting points include DGFT ITC(HS) and CBIC GST schedules; these references do not imply government verification or endorsement of this dataset.
Product relationships
Product names and aliases are a separate editorial layer, not official tariff descriptions. Direct reference matches (A) identify the product expressly. Possible classifications (B) require the stated product characteristics. Related discovery (C) is not a classification answer and cannot qualify a product page by itself. Unresolved intents remain searchable without asserted candidates.
Product evidence uses the dated DGFT Appendix 4RE (5 March 2024), classification wording only. Its RoDTEP percentages are export incentives, not GST, and are never imported as rates. Evidence records retain page numbers and excerpts. This review is not a binding classification ruling or proof of current legal applicability. Chapter labels use the WCO HS 2022 table of contents; Chapter 02 heading labels use its Chapter 02 reference.
The DGFT amendment dated 9 February 2022 deletes legacy phone entries 85171211, 85171219 and 85171290. They remain available as historical seed records in exact lookup, without SEO publication or product recommendations. Every record now has an explicit status. Apart from the three evidenced historical deletions, current legal status remains unreconciled. A match in the dated 2024 export-incentive reference supports only presence in that document; it does not prove current applicability. The 2024 export-policy consultation draft is not treated as an enacted schedule.
Publication and updates
Every record remains searchable. Indexable classification pages require identifying descriptions, reviewed contextual knowledge and, for eight-digit entries, a match in the dated primary reference. Chapters without reviewed context remain browse-only and noindex. Unresolved duplicates, residual-only entries and incomplete or malformed wording are withheld for review. Description length and storage quotas do not decide eligibility.
Updates are reviewed and rebuilt locally before release; there is no live government lookup or automatic rate refresh during browsing. Technical review date: 2026-10-03, which is not a tax-law effective date. Approved code URLs are retained when descriptions change.
