It includes Cyanides, cyanide oxides, complexes

Any special steps when selling Cyanides, cyanide oxides, complexes 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.

Can reverse charge ever apply to transactions involving Cyanides, cyanide oxides, complexes?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Cyanides, cyanide oxides, complexes are forward charge. Check the current notifications for any special cases before deciding.

Does packaging or branding change how GST applies to Cyanides, cyanide oxides, complexes?

Yes. Many food/agri goods are treated differently when sold as pre‑packaged & labelled retail packs versus loose/open packs. If Cyanides, cyanide oxides, complexes 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.

Does MRP, weight or pack size change GST treatment for Cyanides, cyanide oxides, complexes?

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.

Use a delivery challan for sending Cyanides, cyanide oxides, complexes 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.
