## Frequently asked questions

### What products are classified under HSN 3822

It includes Diagnostic reagents

### What misclassification mistakes happen with Diagnostic reagents?

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.

### Any import/export nuance for Diagnostic reagents?

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.

### Do spares or accessories of Diagnostic reagents 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.

### What are the e‑way bill and e‑invoice points while moving Diagnostic reagents?

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 do I bill a kit or combo that includes Diagnostic reagents?

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.
