GST Pro DocsHSN Codes & GST Rates
Assign HSN codes and GST rates to your products — individually, in bulk, or synced from Shopify — including conditional rates and the September 2025 slabs.
Overview
Every product on a GST invoice needs an HSN code and a GST rate so tax is calculated and the HSN-wise tax summary is correct. GST Pro lets you set these per product, edit them in bulk, or sync them from Shopify metafields. Products without their own rate fall back to your default GST rate.
Before you start
- Know the correct HSN code and GST rate for your products (GST Pro ships with a built-in HSN reference to help).
- Decide whether any products use conditional GST (a different rate above/below a sale price threshold).
Steps
Set HSN and GST on a product
Open a product in GST Pro's product setup and enter its HSN code and GST rate. This is stored against the product and used on every invoice that includes it.
Bulk edit HSN and GST
To set many products at once, use bulk edit. Select products, enter the HSN code and rate, and apply — GST Pro writes the values to your products in batches.
Sync HS codes from Shopify
If you already maintain HS codes in Shopify (under product inventory/customs), GST Pro can sync them so you don't re-enter data. Run the sync and review the imported codes.
Conditional GST by sale price (optional)
Some categories are taxed at different rates above and below a price threshold. Enable
conditional GST for those products and set the lower rate (minGst) and the threshold —
GST Pro applies the correct rate based on the line's sale price.
September 2025 GST slabs
For orders created on or after 22 September 2025 (00:00 IST), GST Pro applies the updated September 2025 rates where you've configured them, and the pre-22-Sep rates for earlier orders — so historical invoices stay accurate.
Because the rate depends on the order's creation date, reprinting an old invoice still uses the rate that applied when the order was placed.
Result
Your products carry the right HSN codes and GST rates, tax is calculated correctly, and the HSN-wise tax summary on each invoice is accurate.
