GST on Biscuits, Soap and Namkeen After the 2025 Reform

What actually changed

On 3 September 2025 the 56th GST Council approved the largest restructuring of GST since it launched. The changes took effect on 22 September 2025.

The headline: the four-slab structure became two.

For a distributor, this was not a small administrative change. A large share of what moves through a kirana shop got cheaper overnight, which affected MRPs, margins and every product master in every billing system.

What a kirana actually sells, and where it sits now

The reform moved most daily essentials down to 5%. Soaps, shampoos, hair oil, toothpaste, namkeen, biscuits, noodles, chocolates, ghee and butter all sit in the lower slab.

The items that did not move are where mistakes happen:

• •Detergent and washing preparations stayed at 18%
• •Cosmetics beyond basic skincare, deodorants and perfumes stayed at 18%
• •Aerated drinks, tobacco and pan masala went to 40%

So a single carton going out of your godown can easily carry three different rates: the soap at 5%, the detergent beside it at 18%, and the cold drink at 40%.

Use the HSN Code & GST Rate Finder to check a specific line before you bill it, and the GST Calculator for the CGST/SGST split on the invoice.

The mistake that costs money

The most common error since the reform is not a wrong calculation. It is a stale product master.

Rates are configured per item in Tally, Busy or whatever you bill from. If those were set in 2023 and nobody revisited them, your software is still charging 18% on biscuits that are now 5%.

Two things then happen, neither immediately:

1. 1.You over-collect tax from retailers, which makes your prices uncompetitive against a distributor who updated their masters.
2. 2.Your e-invoice carries a rate that does not match the classification, and your buyer's input tax credit claim can be questioned in scrutiny.

Neither shows up the same week. Both surface at filing or audit, which is the expensive time to find out.

A practical way to audit your masters

You do not need to check every SKU. Work in this order:

1. 1.Sort your item master by turnover. Your top 50 SKUs are most of your billing and most of your exposure.
2. 2.For each, check the rate against the classification — not against what you remember. The HSN finder covers common FMCG categories; the CBIC rate finder is the authority for anything unusual.
3. 3.Flag the three trap categories specifically: detergent, cosmetics, and anything aerated or tobacco-related. These are the lines most likely to be wrong in the other direction — billed at 5% when they should be 18% or 40%, which leaves you owing the differential.
4. 4.Fix loose versus pre-packaged. If you bill both forms of the same commodity, they need separate items with separate rates.

What it did to margins

When a rate falls, the question is who keeps the difference.

Officially, the benefit is meant to reach the consumer through lower prices. In practice the adjustment worked through the chain over several weeks — brands revised MRPs on new packs while old stock at old MRPs was still on shelves.

For a distributor the practical issue was transitional: stock purchased at the old rate, sold at the new one, with input tax credit already claimed at the higher figure. If you carried significant inventory across 22 September, that reconciliation was real work.

A worked example to re-run with your own numbers. Suppose you held ₹8,00,000 of biscuit stock (ex-GST) purchased when the rate was 18%. You claimed ₹1,44,000 of input credit. Selling it at 5% output GST generates ₹40,000 of output tax on the same base — leaving a large credit balance rather than a cash liability. That is not a loss, but it is working capital parked with the department until it is utilised, and it is worth knowing which of your lines did that.

What did not change

Plenty of the mechanics are untouched, and it is worth stating plainly:

• •CGST/SGST versus IGST. Same-state supply still splits into CGST + SGST; inter-state is still a single IGST line at the full rate. The IGST Calculator handles the latter.
• •HSN digit requirements on invoices, tied to turnover.
• •E-invoicing obligations — see GST e-invoicing for Indian distributors.
• •The loose versus pre-packaged distinction for staples.
• •Reverse calculation from an inclusive price — still divide by (1 + rate), never subtract. The Reverse GST Calculator does it correctly.

The checklist

If you have not done this since September 2025:

• •Audit your top 50 SKUs' rates against classification
• •Check detergent, cosmetics and aerated lines specifically — the ones that did not move
• •Separate loose and pre-packaged variants into distinct items
• •Reconcile any transitional credit from stock held across the change
• •Re-check your MRP and margin assumptions with the Retailer Margin Calculator

Rates published here are guidance for common FMCG categories, not a substitute for the CBIC rate finder on a specific HSN code. Where a line is material to your business, confirm it.

What to tell your retailers

Rate changes travel down the chain badly, and the distributor is usually the one explaining them.

Two conversations worth preparing for.

"Why is my invoice different from last month?" If a line moved from 18% to 5%, the tax on their purchase fell. Show the invoice line rather than explaining the reform — the number is more convincing than the policy.

"The MRP has not changed, so where did the benefit go?" This one is harder and worth being straight about. MRPs are set by the brand, and old stock printed at old MRPs stays on shelves for weeks after a rate change. The retailer's margin on that stock improved even though the consumer price did not. Once new stock arrives with revised MRPs, the consumer benefit shows up.

Getting this wrong — implying the retailer is being short-changed when they are not — costs trust that takes months to rebuild.

The classification trap, in detail

The single most useful thing to internalise is that GST follows tariff classification, not the shelf category or the marketing description.

Three examples that catch people:

• •Soap and detergent sit under different headings. One moved to 5%, the other stayed at 18%, and they are next to each other in every shop.
• •Basic skincare and cosmetics diverge similarly. A moisturiser and a colour cosmetic can attract different rates.
• •Loose and pre-packaged staples are treated differently. The same rice is exempt loose and 5% pre-packaged and labelled.

None of these are intuitive from looking at the product. All of them are determined by the HSN code, which is why the code — not the category name — has to be the field your billing system keys on.

A transition check worth doing once

If you carried stock across 22 September 2025, one reconciliation is worth doing even now.

For each major line, compare the input tax credit you claimed on purchase against the output tax you charged on sale. Where a rate fell, you will have claimed credit at the higher rate and charged at the lower one, which accumulates a credit balance rather than a cash liability.

That is not a loss — the credit is usable against other output tax. But it is working capital parked with the department, and knowing which lines did it explains a chunk of any cash-flow oddity from that quarter.

Put the numbers through the GST Calculator at both rates to see the size of it per line.
