No IGST on Ocean Freight for CIF Imports: Madras HC Says Enough Is Enough

Published 25 Aug 2026· 6 min read

The Story

Picture this: you’re an importer who’s already paid IGST on the full value of the goods coming into India — a value that already bundles in the shipping cost and the insurance. Then the tax department asks you to pay IGST again, this time specifically on the ocean freight, because a foreign shipping line technically “supplied a service” getting your cargo here.

That’s being taxed twice for the same journey. And it’s exactly the argument the Supreme Court accepted years ago in Union of India v. Mohit Minerals.

Yet here we are in 2026, and importers are still fighting this same battle at the ground level. Case in point: M/s. MGM Oil Mills Pvt Ltd v. Union of India, decided by the Madras High Court on 12 August 2026.

Some background first. When you import on a CIF basis — Cost, Insurance and Freight — the price already bundles in shipping and insurance. Under GST law that’s a “composite supply,” and Section 8 of the CGST Act says a composite supply is taxed as one thing, not sliced into separate taxable pieces.

But two 2017 notifications — 10/2017-Integrated Tax (Rate) and 8/2017-Integrated Tax (Rate) — required importers to pay IGST separately on ocean freight too, under reverse charge, as if the shipping line’s freight were its own distinct taxable supply.

MGM Oil Mills had already paid IGST on the full CIF value. Then it got hit with a fresh demand on the freight component. So it went to court.

The Madras High Court didn’t strike the notifications down — they remain validly issued under Sections 5(3) and 5(4) of the IGST Act. What it said instead is narrower, and directly useful: once IGST has already been paid on the full composite CIF value, taxing the freight portion again separately breaks Section 8. Demand quashed.

Sidebar: MGM Oil Mills didn’t just want the demand cancelled — it specifically asked for a refund of tax it had already paid, under the wrong head (CGST/SGST instead of IGST). Worth remembering if a client’s already paid up under the wrong head.

So if you’ve got import clients on CIF terms sitting on a similar ocean-freight demand — or who already paid one — this is your citation.

Why It Matters

This ruling directly affects any importer who has paid, or been assessed, IGST on ocean freight under RCM in addition to IGST already paid on the full CIF value of imported goods — a double-taxation exposure that has recurred in GST litigation since Mohit Minerals was decided by the Supreme Court, yet continues to generate fresh demand orders and refund disputes at the field level. For CA firms advising importer clients, this is a direct, actionable precedent for resisting fresh demands and pursuing refund claims for excess tax paid under the wrong head.

Key Takeaways

Where an importer has already paid IGST on the full CIF value of imported goods (a composite supply including freight and insurance), a separate IGST levy on the ocean freight component under RCM violates Section 8 of the CGST Act.
The underlying rate notifications (No. 10/2017-IT(Rate) and No. 8/2017-IT(Rate), Sl. No. 9(ii)) were not struck down as such — they remain validly issued under Sections 5(3)/5(4) of the IGST Act — but their application to CIF-basis imports, where IGST has already been discharged on the composite value, was held impermissible.
The Madras High Court’s ruling directly follows and applies the Supreme Court’s binding precedent in Union of India v. Mohit Minerals Pvt. Ltd.
Importers who paid the disputed IGST under the wrong head (or under CGST/SGST instead of IGST) may have a live refund claim; the petitioners in this matter specifically sought refund of excess amounts paid under CGST/SGST instead of IGST.
This is a High Court ruling applying settled Supreme Court law to specific facts — it strengthens, but does not newly create, the underlying legal position; practitioners should still confirm limitation periods before advising a client to pursue a fresh refund claim.

Practical Implications

Any CA firm with importer clients — particularly in commodities, textiles, and bulk trading where CIF contracts are standard — should review whether IGST has been separately demanded, paid, or is currently under dispute on ocean freight under RCM. Where a demand order has been passed treating ocean freight as a separate taxable service despite the importer having paid IGST on the full CIF value, this ruling provides direct persuasive (and, within Tamil Nadu, binding) authority to challenge the order. Where excess tax was paid — including under the wrong head (CGST/SGST instead of IGST) — a refund claim should be evaluated, subject to the applicable limitation period under Section 54 of the CGST Act.

Action Checklist

Identify all import clients who transact on a CIF basis and review whether any GST demand, SCN, or assessment has separately taxed ocean freight under RCM.
Where a demand exists, cite M/s. MGM Oil Mills Pvt Ltd v. Union of India (Madras HC, 12 August 2026) alongside the Supreme Court’s Mohit Minerals ruling in the reply/appeal.
For clients who already paid the disputed tax (including under the wrong head), evaluate a Section 54 refund claim and confirm the limitation period has not lapsed.
Do not treat this ruling as invalidating the underlying rate notifications generally — the notifications remain valid; only their application to CIF imports where IGST is already paid on the composite value is affected.

FAQs

Q: Does this ruling mean IGST on ocean freight under RCM is abolished entirely?
A: No. The rate notifications imposing IGST on ocean freight services under RCM remain validly issued. What the Court held is that where the importer has already paid IGST on the full CIF value of goods (a composite supply that includes freight), a separate levy on the freight component specifically violates Section 8 of the CGST Act.

Q: My client already paid the disputed IGST. Can they claim a refund now?
A: Potentially — the petitioners in this matter specifically sought (and the ruling supports) refund of excess tax paid under the wrong head. Any refund claim remains subject to the limitation period under Section 54 of the CGST Act.

Q: Does this ruling bind authorities outside Tamil Nadu?
A: It is a Madras High Court ruling and is directly binding within its territorial jurisdiction; elsewhere in India it carries strong persuasive value.
