## Frequently asked questions

### What products are classified under HSN 2811

It includes Inorganic acids

### How do I bill a kit or combo that includes Inorganic acids?

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.

### Do spares or accessories of Inorganic acids follow the same HSN?

Not always. Spares are often classified by their own description or by the function/part rule. Check if a specific sub‑heading exists for parts of the main item and describe the part on the invoice.

### How are warranty replacements of Inorganic acids 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.

### Does packaging or branding change how GST applies to Inorganic acids?

Yes. Many food/agri goods are treated differently when sold as pre‑packaged & labelled retail packs versus loose/open packs. If Inorganic acids is sold in small pouches (e.g., 500 g) with an MRP and label, record that on the invoice. Loose bulk bags often follow a different treatment.

### Can I claim ITC on inputs and services used for Inorganic acids?

If your outward supply of Inorganic acids 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 misclassification mistakes happen with Inorganic acids?

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.
