Concessional GST for vessel parts applies only when marine engines are supplied as components of qualifying vessels.

Marine engines and spare parts supplied as components of fishing vessels under heading 8902, and of defence, patrol, flood relief and rescue vessels under heading 8906, qualify for 5% GST; if supplied for other uses, the rate under their own tariff heading applies. Warranty-period goods and labour supplied without separate consideration are not independently taxable, as they form part of the original warranty obligation. Repair and maintenance of fishing vessels is generally a composite service taxable at 18% GST, but separately invoiced parts and labour are taxed at their respective rates. Puff insulated iceboxes remain classifiable under heading 3923 and attract 18% GST.

Issues: (i) Whether marine engines and their spare parts supplied for use as part of fishing vessels under heading 8902 are taxable at 5% GST; (ii) Whether goods and labour supplied free of cost during warranty period for fishing vessels are liable to GST; (iii) Whether repair and maintenance of fishing vessels is taxable at 5% GST or at the rate applicable to the service and the separately supplied parts; (iv) Whether puff insulated iceboxes used in fishing vessels are eligible for concessional GST as parts of fishing vessels; (v) Whether marine engines supplied for defence, patrol, flood relief and rescue vessels are taxable at 5% GST.

Issue (i): Whether marine engines and their spare parts supplied for use as part of fishing vessels under heading 8902 are taxable at 5% GST.

Analysis: Marine engines classified under heading 8407 are generally taxable at 28%, while fishing vessels under heading 8902 attract 5% GST. The decisive factor is whether the engine is supplied as a part of a fishing vessel. Parts of goods of heading 8902 falling under any chapter of the tariff are covered by the concessional entry in the rate notification. The ruling also follows the CBIC clarification on marine engines for fishing vessels.

Conclusion: Yes. Marine engines and spare parts supplied for use as part of fishing vessels under heading 8902 are taxable at 5% GST. If supplied for other use, the rate applicable to their own tariff heading applies.

Issue (ii): Whether goods and labour supplied free of cost during warranty period for fishing vessels are liable to GST.

Analysis: Warranty repair or replacement forms part of the original contract consideration. Where supplies are made in discharge of the warranty obligation without separate consideration, they are incidental to the original supply and do not constitute a taxable supply by themselves. GST arises only if additional consideration is charged for such supplies.

Conclusion: No. Supplies made free of cost during the warranty period in discharge of the warranty obligation are not liable to GST, subject to taxability if additional consideration is received.

Issue (iii): Whether repair and maintenance of fishing vessels is taxable at 5% GST or at the rate applicable to the service and the separately supplied parts.

Analysis: Repair and maintenance involving spare parts and labour is ordinarily a composite supply, with the service of repair or maintenance as the principal supply. Such service is classifiable under SAC 998714 and attracts 18% GST. However, if the contract and invoices separately identify the parts and the labour, the two become distinct supplies and are taxed at their respective rates. Spare parts supplied as part of fishing vessels attract 5%, while the service element attracts 18%.

Conclusion: Repair and maintenance service of fishing vessels is taxable at 18% GST as a service. Where parts and services are separately charged and separately shown, the parts attract 5% GST and the service attracts 18% GST.

Issue (iv): Whether puff insulated iceboxes used in fishing vessels are eligible for concessional GST as parts of fishing vessels.

Analysis: Puff insulated iceboxes are classifiable under heading 3923 and are liable to GST at 18%. They are not treated as parts of fishing vessels under heading 8902 merely because they are used on fishing vessels for preservation of fish and maintenance of hygiene.

Conclusion: No. Puff insulated iceboxes fall under heading 3923 and attract 18% GST.

Issue (v): Whether marine engines supplied for defence, patrol, flood relief and rescue vessels are taxable at 5% GST.

Analysis: Vessels used for defence, patrol, relief and rescue operations fall under heading 8906. Parts of goods of heading 8906, falling under any tariff chapter, are covered by the concessional 5% entry. A marine engine supplied as part of such a vessel is therefore eligible for the concessional rate.

Conclusion: Yes. Marine engines supplied as parts of vessels under heading 8906 for defence, patrol, flood relief and rescue operations attract 5% GST.

Final Conclusion: The ruling grants concessional treatment only where the marine engine is supplied as a component of a qualifying vessel, denies exemption to warranty supplies made without consideration, treats repair and maintenance as a taxable service, and holds that puff insulated iceboxes are taxable at the general rate applicable to heading 3923.

Ratio Decidendi: A tariff-concessional rate for a part applies only when the part is supplied as part of the qualifying vessel, while warranty supplies without separate consideration are not independent taxable supplies and repair contracts are taxed according to whether they constitute a composite supply or separately identifiable supplies.
