"What is an HSN code? (and why product listings mention it)"
An HSN code is a standard classification number for products, used so that goods are described the same way across invoices and tax records, and you should look yours up from official lists.

If you have browsed supplier invoices or marketplace listing forms, you may have seen a field asking for the HSN code of your product. It appears next to the name and price, and nobody explains it. Here is what the idea is and how a small seller should treat it.
The concept
HSN stands for Harmonised System of Nomenclature, a system for classifying goods using a numbered scheme. The point is that a product has a standard number tied to what kind of product it is, so that a cotton kurta is described in the same way whether it is sold in Jaipur or Chennai. Governments and businesses use these codes to organise tax and trade records.
I am not stating specific codes or how they connect to tax rates, because I would risk being wrong for your product or out of date. The official lists are public, and a CA can tell you which code fits an item. That is the only reliable way.
Why a listing or invoice may ask for it
When a tax invoice is issued, it commonly describes each item and may include its classification code. Some platforms and tools also ask for the code when you add a product, so that invoices can be generated properly. If you are a small seller who is not yet registered, you may never be asked. If you are registered, or become so, it will come up quickly.

How to find the right one for your product
Do not copy a code from a competitor and assume it is right. Their product may be different, or they may have it wrong.
- Write a precise description of your product, including the material and how it is used. A cotton scarf and a silk scarf may not be the same thing in the classification.
- Look up the official classification list published by the government on its portal.
- Ask your CA to confirm the code, especially for products that sit between categories, such as gift hampers made of mixed items.
- Write the code and the date you confirmed it into your catalogue sheet, so you do not search again.
Where it fits in your catalogue
A good catalogue sheet has columns for the basics, such as name, SKU, price, weight and dimensions. If you will need a classification code, add a column for it. Catalogue spreadsheet columns every seller needs can guide the layout, and how to plan your catalogue before uploading helps you gather data before you start entering it.
I have not found a dedicated HSN field in the Varchas Stores product editor, so if you need to keep one, hold it in your own sheet for now and ask your accountant how it should appear on your invoices.
Mixed products and bundles
A bundle of several items, for example a gift set with a candle, a mug and a card, can be tricky. It may not be obvious which classification applies to the set. This is a perfect question for your CA rather than a guess. Take a clear photo and a list of contents to the meeting.
Keep it simple
You do not need to memorise any codes. You need to know that they exist, that each product may have one, and that the correct answer comes from the official list and an accountant. Gather your product details in one tidy sheet, ask once, and record the answers. Then the field on a form stops being a mystery and becomes one more box you can fill with confidence.
