Submarine decoy system classification as part of a warship confirmed for GST at the lower schedule rate.

A customized decoy system permanently fitted in a submarine and used solely for its operational protection was treated as an integral and essential part of the warship, not as an independent good. Its lack of separate market use and its close functional nexus with the submarine supported classification under Chapter 8906 as parts of submarine. On that basis, the supply was held eligible for GST at 5% under Entry No. 252 of Schedule I.

Issues: Whether the Submarine Fired Decoy System supplied for use in submarines is classifiable as parts of submarine under Chapter Heading 8906 and whether it attracts GST at 5% under Entry No. 252 of Schedule I.

Analysis: The supply was examined in the context of submarines used by the Indian Navy as warships. The system was found to be permanently fitted in a designated space, customized for submarine use, and to have no independent market use apart from countering torpedo attacks. On that basis, its identity in commercial parlance and its functional nexus with the submarine showed that it was an integral and essential part of the warship. The reasoning also followed the approach adopted in prior advance rulings treating defence systems fitted to submarines as parts of the vessel rather than as arms or independent goods.

Conclusion: The Submarine Fired Decoy System is classifiable as parts of submarine under Chapter 8906 and is eligible for GST at 5% under Entry No. 252 of Schedule I.

Ratio Decidendi: A customized system permanently fitted to a submarine and used solely for its operational protection is classifiable as a part of the submarine when it has no independent marketable use apart from that vessel.
