## Frequently asked questions

### What products are classified under HSN 1605

It includes Amide-function compounds

### If I repair and return Amide-function compounds, 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.

### How do I bill a kit or combo that includes Amide-function compounds?

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.

### Can reverse charge ever apply to transactions involving Amide-function compounds?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Amide-function compounds are forward charge. Check the current notifications for any special cases before deciding.

### How should I document Amide-function compounds sent for job work?

Use a delivery challan for sending Amide-function compounds 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.

### Any special steps when selling Amide-function compounds through an e‑commerce platform?

Ensure registration requirements are met and reconcile the operator’s TCS statements with your GSTR‑2B/3B. Map SKU descriptions to HSN to reduce mismatches and returns.
