## Frequently asked questions

### What products are classified under HSN 2925

It includes Carboxyimide compounds

### Any import/export nuance for Carboxyimide compounds?

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.

### What misclassification mistakes happen with Carboxyimide compounds?

Using a broad or incorrect HSN, ignoring material/form (e.g., raw vs processed), or mixing goods and services on one line. Always match wording to the HSN Notes and keep a classification working paper.

### How are warranty replacements of Carboxyimide compounds handled?

If replacement is without consideration under a pre‑agreed warranty, issue a delivery challan and reference the original invoice/contract. If consideration is charged, raise a tax invoice. Keep serial/lot details for traceability.

### Can reverse charge ever apply to transactions involving Carboxyimide compounds?

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

### How should I document Carboxyimide compounds sent for job work?

Use a delivery challan for sending Carboxyimide 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 Carboxyimide 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.
