## Frequently asked questions

### What products are classified under HSN 2839

It includes Silicates: Alkali metal silicates

### How are warranty replacements of Silicates: Alkali metal silicates 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.

### What misclassification mistakes happen with Silicates: Alkali metal silicates?

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.

### Is the composition scheme suitable if I mainly trade Silicates: Alkali metal silicates?

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 do I bill a kit or combo that includes Silicates: Alkali metal silicates?

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.

### Any special steps when selling Silicates: Alkali metal silicates 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.
