## Frequently asked questions

### What products are classified under HSN 3818

It includes Doped chemical elements

### What are the e‑way bill and e‑invoice points while moving Doped chemical elements?

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.

### How should I document Doped chemical elements sent for job work?

Use a delivery challan for sending Doped chemical elements 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 Doped chemical elements?

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.

### Do spares or accessories of Doped chemical elements 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.

### If I repair and return Doped chemical elements, 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.

### Any import/export nuance for Doped chemical elements?

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.
