## Frequently asked questions

### What products are classified under HSN 3815

It includes Catalytic preparations

### Does MRP, weight or pack size change GST treatment for Catalytic preparations?

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.

### How do I bill a kit or combo that includes Catalytic preparations?

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.

### Is the composition scheme suitable if I mainly trade Catalytic preparations?

The composition scheme is optional for eligible small suppliers of goods. You cannot issue tax invoices or collect tax under composition. Check turnover limits and exclusions; evaluate margins and ITC loss before opting in.

### How should I document Catalytic preparations sent for job work?

Use a delivery challan for sending Catalytic preparations 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 I claim ITC on inputs and services used for Catalytic preparations?

If your outward supply of Catalytic preparations 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.

### What are the e‑way bill and e‑invoice points while moving Catalytic preparations?

Generate an e‑way bill when the consignment value exceeds ₹50,000, unless exempted for the transaction. E‑invoicing depends on turnover (AATO threshold as notified) for B2B supplies, not on the item itself.
