Frequently Asked Questions

Clear answers to common queries about HSN Sub Chapter 2918 and GST compliance.

What products are classified under HSN 2918

It includes Carboxylic acids and derivatives

If I repair and return Carboxylic acids and 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.

Does packaging or branding change how GST applies to Carboxylic acids and derivatives?

Yes. Many food/agri goods are treated differently when sold as pre‑packaged & labelled retail packs versus loose/open packs. If Carboxylic acids and derivatives 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 Carboxylic acids and derivatives?

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.

Does MRP, weight or pack size change GST treatment for Carboxylic acids and 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.

Can reverse charge ever apply to transactions involving Carboxylic acids and derivatives?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Carboxylic acids and derivatives are forward charge. Check the current notifications for any special cases before deciding.
