What classifiers are covered in this India reference hub?

The hub connects NIC 2025 activity codes, NCO-2015 occupation pages, and source-ready layers for HSN/ITC-HS goods, SAC services and InSCED education fields.

Why connect NIC with HSN, SAC, NCO and InSCED?

Users often need to move from a business activity to related goods, services, occupations and education pathways. Cross-classifier links reduce dead ends and make classification workflows easier to verify.

Are all classifier datasets loaded?

NIC 2025 and NIC 2008 are loaded. NCO, HSN, SAC and InSCED source layers are tracked by source-readiness checks and are only expanded when official source snapshots are available locally.

How the classifiers fit together

NIC describes the economic activity of an establishment. NCO describes occupations. HSN/ITC-HS describes goods, SAC describes services, and InSCED describes education fields. Keeping them in one hub helps users move from business registration to products, services, workforce roles and training pathways without treating any single classifier as a legal substitute.

Comparison guides

Use these pages when the user knows one classifier but needs to understand which system answers the actual workflow question.

NIC vs HSN

Use NIC for business activity and HSN for goods, GST goods rates and product-level trade references.

NIC vs SAC

Use NIC for activity registration and SAC for GST service classification and invoicing.

NCO vs NIC

Use NCO for occupations and NIC for establishments, industries and business activity.

Classifier hub FAQ

What is the main classifier on this site?

NIC 2025 is the main loaded directory and the primary activity-code layer for India.

Can I use this as official filing advice?

No. This is an independent reference site. Use it to research and verify, then confirm critical decisions in official government sources.

Why do some classifiers show zero records?

Those layers are source-ready but not populated until official structured source snapshots are placed in the matching local source folder.
