How HSN gets done today

HSN guesses, until the GST officer asks.

The accountant Googles the HSN. The result is from a 2018 article. The rate has changed twice since. The notification reference is wrong. The ITC eligibility is uncertain. The classification gets used on 200 invoices before someone notices:

  • The 8-digit code on the invoice doesn't match the 6-digit one in the GSTR-1 summary.
  • The rate at sale (18%) and the rate the CBIC notification carries (12%) are different. ITC reverses.
  • The exemption claimed under Notification 12/2017 expired in FY 2022-23. The team is still claiming it.
  • When the GST officer asks for the basis of classification, the answer is 'a Google search'.

Classifying against the live CBIC master with a documented review and a locked audit trail is the difference between an HSN you can defend and one you can't.

How it works

From search to locked classification.

Step 01

Live search against CBIC

Free-text search against the CBIC HSN master, refreshed nightly. AI ranks suggestions by your historical mapping for similar items.

Step 02

Rate and ITC surfaced

Per result: GST rate (CGST + SGST or IGST), compensation cess where applicable, ITC eligibility (full, restricted, blocked) and the notification reference.

Step 03

Reviewer approves

Tax reviewer (controller, CA) approves the classification before it locks on the item. Confidence and rationale captured.

Step 04

Rate changes propagate

When CBIC notifies a rate change, affected items surface for re-review. New rate applies prospectively from the notification date. Historic transactions retain the rate at posting.

Defensible classification, by design.

When the GST officer asks for the basis of classification, the audit trail shows the CBIC reference, the reviewer, the rationale and the date. This is the level of documentation the law expects.

HSN Code Finder FAQ

What buyers ask.

4-digit, 6-digit or 8-digit HSN. Which does the system use?

The system stores the 8-digit Customs Tariff classification per item. GSTR-1 summary uses the 6-digit (mandatory above ₹5 crore turnover) or 4-digit (₹5 crore and below) per current rules. The detail-level classification stays available for audit even where the summary is shorter.

A CBIC rate change happens mid-quarter. What about pending invoices?

Rate changes apply prospectively from the notification effective date. Invoices issued before the date keep the old rate; invoices on or after carry the new rate. The system handles the cut-over automatically.

How does AI classification compare to a human-only approach?

AI ranks candidates against the CBIC master plus your organisation's historical mapping. The reviewer always approves; AI does not lock without human sign-off. Where the AI confidence is below threshold, the item routes to a senior reviewer (typically the CA) before locking.

Items where the HSN is genuinely contested between two codes?

The classification record supports a 'rationale' field where the reasoning is captured. Where the position is contested, a request for advance ruling can be drafted from the system. The lock holds the chosen classification with the documented reasoning.
