What products are classified under HSN 2904

It includes Hydrocarbon derivatives

What misclassification mistakes happen with Hydrocarbon derivatives?

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.

Does MRP, weight or pack size change GST treatment for Hydrocarbon derivatives?

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.

If I repair and return Hydrocarbon derivatives, 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.

Is the composition scheme suitable if I mainly trade Hydrocarbon derivatives?

The composition scheme is optional for eligible small suppliers of goods. You cannot issue tax invoices or collect tax under composition. Check turnover limits and exclusions; evaluate margins and ITC loss before opting in.

Any special steps when selling Hydrocarbon derivatives 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.
