HSN 9024: Machines and appliances for testing the hardness

HSN code 9024 covers: Machines and appliances for testing the hardness, strength, compressibility, elasticity of other mechanical properties of materials (e.g. metals, wood, textiles, paper, plastics).

The GST rate for this code depends on the specific item (per CBIC Notification 9/2025-Central Tax (Rate), effective 22 Sep 2025). The official schedule lists:

• 5% — Coronary stents and coronary stent systems for use with cardiac catheters
• 18% — Machines and appliances for testing the hardness, strength, compressibility, elasticity or other mechanical properties of materials (for example, metals, wood, textiles, paper, plastics)

Pick the line that matches what you're billing.

Rates reflect the 22 Sep 2025 GST 2.0 reform (mainly 5% and 18%, with 3% for precious metals and 28%/40% for select sin and luxury goods). This is a reference drawn from the CBIC rate schedule, not tax advice — confirm the exact rate for your specific item with your CA.
