## Frequently asked questions

### What products are classified under HSN 2815

It includes Sodium & potassium hydroxides

### Do spares or accessories of Sodium & potassium hydroxides 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 should I document Sodium & potassium hydroxides sent for job work?

Use a delivery challan for sending Sodium & potassium hydroxides 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.

### What should my invoice and records include for Sodium & potassium hydroxides?

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.

### Can I claim ITC on inputs and services used for Sodium & potassium hydroxides?

If your outward supply of Sodium & potassium hydroxides 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 are the e‑way bill and e‑invoice points while moving Sodium & potassium hydroxides?

Generate an e‑way bill when the consignment value exceeds ₹50,000, unless exempted for the transaction. E‑invoicing depends on turnover (AATO threshold as notified) for B2B supplies, not on the item itself.
