HSN (Harmonized System of Nomenclature)
6-8 digit code that classifies goods for GST reporting (the goods equivalent of SAC).
HSN is an internationally standardised code (World Customs Organization taxonomy) used in India under the CGST Rules to classify goods for GST. India uses 6, 8, or rarely 4-digit HSN depending on the supplier's aggregate turnover and customer type. Most freelancers do not deal with HSN since they provide services (which use SAC), but freelance product sellers (e.g., illustrators selling prints, photographers selling stock photos) need HSN.
Worked example
A freelance illustrator selling Rs. 50,000 of art prints would use HSN 4911 (printed pictures) at 12% GST, not a SAC. Mixed engagements (digital design + print delivery) need both: SAC for the design service line, HSN for the print line.
Practitioner tip
If your invoice has both goods and services, list separate line items with their own HSN/SAC and rate — never collapse them under one heading even if the customer pays a single total.
