## Frequently asked questions

### What products are classified under HSN 2512

It includes Siliceous earths, calcined or unworked

### How should I document Siliceous earths, calcined or unworked sent for job work?

Use a delivery challan for sending Siliceous earths, calcined or unworked to the job worker. Declare movement in your records and reconcile when the goods return. If the job worker raises a service invoice, classify it under SAC; your goods remain under the original HSN.

### Can reverse charge ever apply to transactions involving Siliceous earths, calcined or unworked?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Siliceous earths, calcined or unworked are forward charge. Check the current notifications for any special cases before deciding.

### Can I claim ITC on inputs and services used for Siliceous earths, calcined or unworked?

If your outward supply of Siliceous earths, calcined or unworked is taxable, ITC is generally available (Sections 16–17) except blocked credits (e.g., personal use, motor vehicles in most cases). For exempt supplies, proportionate reversal is required under Rule 42/43.

### Does MRP, weight or pack size change GST treatment for Siliceous earths, calcined or unworked?

Some entries use MRP/weight‑based conditions for classification. Keep pack size, retail marking and brand status on records and invoice to support the chosen HSN.

### If I repair and return Siliceous earths, calcined or unworked, 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.
