Frequently Asked Questions
What is the HSN code for instruments and apparatus for physical or chemical analysis?
The HSN code for instruments and apparatus for physical or chemical analysis is 9027, under Chapter 90 (Optical, photo, medical & measuring instruments).
What is the GST rate on instruments and apparatus for physical or chemical analysis?
It depends on the specific item: instruments and apparatus for medical, surgical, dental or veterinary uses, for physical or chemical analysis is 5%; instruments and apparatus for physical or chemical analysis (for example, polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus); instruments and apparatus for measuring or checking viscosity, porosity, expansion, surface tension or the like; instruments and apparatus for measuring or checking quantities of heat, sound or light (including exposure meters); microtomes [other than instruments and apparatus for medical, surgical, dental or veterinary uses for physical or chemical analysis] is 18%.
How many digits of the HSN code go on a GST invoice?
It depends on your turnover in the previous financial year: businesses above ₹5 crore generally show 6 digits (8 for certain specified goods), and smaller businesses show 4 digits on B2B invoices. Check the current e-invoicing/HSN notification for the exact threshold that applies to you.
