## Frequently asked questions

### What products are classified under HSN 2917

It includes Polycarboxylic Acids

### Any special steps when selling Polycarboxylic Acids 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.

### What should my invoice and records include for Polycarboxylic Acids?

Include HSN, exact description, pack size/grade, quantity, and if pre‑packaged & labelled. Maintain purchase specs, test reports (where relevant), and job‑work challans for audit trail.

### How do I bill a kit or combo that includes Polycarboxylic 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 Polycarboxylic 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.

### Does MRP, weight or pack size change GST treatment for Polycarboxylic Acids?

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.
