FAQs for Sub Chapter 2809

What products are classified under HSN 2809

It includes Phosphoric & polyphosphoric acids

If I repair and return Phosphoric & polyphosphoric acids, 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.

Does MRP, weight or pack size change GST treatment for Phosphoric & polyphosphoric 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.

Any import/export nuance for Phosphoric & polyphosphoric acids?

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.

How should I document Phosphoric & polyphosphoric acids sent for job work?

Use a delivery challan for sending Phosphoric & polyphosphoric acids 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.

Can I claim ITC on inputs and services used for Phosphoric & polyphosphoric acids?

If your outward supply of Phosphoric & polyphosphoric 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.
