Solar water heater parts may fall under Heading 8419, but heat-only collectors do not qualify for concessional IGST.

Evacuated Tube Collectors were treated as integral parts of solar water heater systems and, on that basis, classifiable under Heading 8419 of the Customs Tariff Act, 1975. However, the concessional 5% IGST entry for renewable energy devices did not apply because the product absorbs solar energy to produce heat for water heating and does not generate electricity from solar energy. The ruling therefore distinguishes between a solar water heating component and a solar power based device, limiting the concessional rate to products operating through electricity generated from solar energy.

Issues: (i) Whether Evacuated Tube Collectors are classifiable under Heading 8419 of the Customs Tariff Act, 1975 as parts of solar water heater systems; (ii) Whether the product is entitled to concessional IGST at 5% under Sl. No. 234 of Schedule I of Notification No. 1/2017-Integrated Tax (Rate) dated 28.06.2017 as a solar power based device or part thereof.

Issue (i): Whether Evacuated Tube Collectors are classifiable under Heading 8419 of the Customs Tariff Act, 1975 as parts of solar water heater systems.

Analysis: The product was found to be an integral part of the solar water heater system, which consists mainly of the tubes and an insulated tank. Heading 8419 covers water heaters, and the parts of such systems are also classifiable within that heading. The arrangement of the tubes and their function in heating water supported classification as a part of the solar water heater system.

Conclusion: Yes. The product was held classifiable under Heading 8419.

Issue (ii): Whether the product is entitled to concessional IGST at 5% under Sl. No. 234 of Schedule I of Notification No. 1/2017-Integrated Tax (Rate) dated 28.06.2017 as a solar power based device or part thereof.

Analysis: The concessional entry applies to renewable energy devices and parts falling under Chapters 84 or 85, including solar power based devices. The ruling treated "solar power" as electricity generated from solar energy and held that devices covered by the entry must operate through such electricity. The Evacuated Tube Collector only absorbs solar energy and converts it into heat for water heating; it does not generate electricity at any stage. On that basis, it was not treated as a solar power based device or part thereof for the exemption entry.

Conclusion: No. The product was held not entitled to the concessional 5% IGST rate under the notification.

Final Conclusion: The product was accepted as classifiable under Heading 8419, but the concessional GST benefit claimed under the renewable energy entry was denied.

Ratio Decidendi: A device qualifies as a solar power based device for the concessional entry only if it operates through electricity generated from solar energy, and a product that merely converts solar energy into heat without generating electricity does not satisfy that requirement.
