Frequently Asked Questions

Clear answers to common queries about HSN Sub Chapter 2521 and GST compliance.

What products are classified under HSN 2521

It includes Limestone & calcareous stones

If I repair and return Limestone & calcareous stones, how should I charge GST?

Repair/service is a service supply (SAC). Parts and materials used are goods and may be billed separately with HSN. Mention both lines clearly to avoid mixing service and goods values.

Can reverse charge ever apply to transactions involving Limestone & calcareous stones?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Limestone & calcareous stones are forward charge. Check the current notifications for any special cases before deciding.

Any import/export nuance for Limestone & calcareous stones?

Exports are zero‑rated (with or without payment of IGST) subject to LUT/refund conditions. Imports may attract customs duties in addition to GST. Keep HSN‑wise description consistent across invoice, shipping bill and BOE.

How do I bill a kit or combo that includes Limestone & calcareous stones?

Prefer separate lines per item with its HSN so each component follows its own tax treatment. If it is a naturally bundled supply, identify the principal supply and tax the whole bundle accordingly.

Do spares or accessories of Limestone & calcareous stones follow the same HSN?

Not always. Spares are often classified by their own description or by the function/part rule. Check if a specific sub‑heading exists for parts of the main item and describe the part on the invoice.

Does packaging or branding change how GST applies to Limestone & calcareous stones?

Yes. Many food/agri goods are treated differently when sold as pre‑packaged & labelled retail packs versus loose/open packs. If Limestone & calcareous stones is sold in small pouches (e.g., 500 g) with an MRP and label, record that on the invoice. Loose bulk bags often follow a different treatment.
