HSN / SAC Code Lookup
Source: GSTN portal.
Where to look
The Government maintains the authoritative search at:
- **HSN lookup (goods):** Available on the GST portal at **gst.gov.in → Services → User Services → Search HSN Code**
- **SAC lookup (services):** Same portal section
- Direct CBIC tariff page: **cbic.gov.in**
These are the only sources we recommend — they are kept current with the Customs Tariff and any rate / notification changes.
Current HSN reporting mandate
Source: Notification 78/2020-CT dated 15 October 2020.
- **AATO up to Rs. 5 crore** — minimum **4-digit HSN** on B2B invoices; HSN optional on B2C
- **AATO above Rs. 5 crore** — minimum **6-digit HSN** on all invoices (B2B and B2C)
- **8-digit HSN** mandatory for specified notified chemicals and certain other products regardless of turnover
How to use the lookup
1. Visit gst.gov.in → "Services" → "User Services" → "Search HSN Code" 2. Enter either the product description or a known HSN prefix 3. The portal returns matching codes with description and applicable GST rate 4. Cross-verify against the actual product invoice description before finalising
When to seek expert help
- The same product may fall under multiple HSN codes depending on processing, composition, or use — pick the one that best fits and document the rationale
- A wrong HSN with the correct rate is generally a procedural issue; a wrong HSN with the wrong rate triggers reassessment and short payment of tax
- For composite supplies / mixed supplies / works contracts, the classification rules are more nuanced — consult before invoicing
