India adopted the 6-digit HSN system for GST classification in 2017. The mandatory digit requirements are based on annual turnover: 4 digits for turnover below ₹5 crore, 6 digits for above ₹5 crore, and 8 digits for all exports.
SAC codes (Services Accounting Codes) are used for all services. They follow the same 6-digit structure. Examples: 996311 (Hotels), 998313 (Custom software), 999100 (Government services).
