What products are classified under HSN 7903

It includes Zinc dust, powders & flakes

How are warranty replacements of Zinc dust, powders & flakes handled?

If replacement is without consideration under a pre‑agreed warranty, issue a delivery challan and reference the original invoice/contract. If consideration is charged, raise a tax invoice. Keep serial/lot details for traceability.

Can reverse charge ever apply to transactions involving Zinc dust, powders & flakes?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Zinc dust, powders & flakes are forward charge. Check the current notifications for any special cases before deciding.

How do I bill a kit or combo that includes Zinc dust, powders & flakes?

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.

Does packaging or branding change how GST applies to Zinc dust, powders & flakes?

Yes. Many food/agri goods are treated differently when sold as pre‑packaged & labelled retail packs versus loose/open packs. If Zinc dust, powders & flakes is sold in small pouches (e.g., 500 g) with an MRP and label, record that on the invoice. Loose bulk bags often follow a different treatment.

Any import/export nuance for Zinc dust, powders & flakes?

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.

Any special steps when selling Zinc dust, powders & flakes 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.
