Why do so many codes just say "Other"?
"Other" covers everything in a heading not listed separately. Look up the code to see the headings above it, which say what it belongs to.
Does this show the GST rate?
Not yet. Rates changed in September 2025, and we're checking each one against the CBIC rate notifications before showing it.
Where do these codes come from?
The HSN and SAC master file published on the GST portal. We refresh it every month.
