Tariff classification of industrial computing components places the power supply unit with static converters, triggering BIS compliance and duty relief.
Tariff classification requires separately imported components to be assessed under their specific headings and the Section XVI notes. The Motherboard falls under Tariff Item 8473 30 20, while the model-specific Chassis, being solely or principally suitable for an automatic data processing machine and lacking independent coverage, falls under Tariff Item 8473 30 99. The Power Supply Unit, as a static converter independently described under Heading 8504, falls under Tariff Item 8504 40 29 rather than as a machine part. Its classification brings it within applicable BIS certification requirements at import. It may also qualify for basic customs duty exemption as a static converter for an automatic data processing machine, subject to prescribed conditions and import-time verification.
Issues: (i) Tariff classification of the Motherboard, Chassis and Power Supply Unit proposed for assembly of the Industrial Computing Platform. (ii) Applicability of BIS certification requirements to the Power Supply Unit. (iii) Eligibility of the Power Supply Unit for basic-customs-duty exemption under Serial No. 4 of Notification No. 25/2005-Cus. dated 01.03.2005.
Issue (i): Tariff classification of the Motherboard, Chassis and Power Supply Unit proposed for assembly of the Industrial Computing Platform.
Analysis: Under Rule 1 of the General Rules for the Interpretation of the Import Tariff, classification follows the terms of the headings and the relevant Section and Chapter Notes. The complete Industrial Computing Platform satisfies Note 6(A) to Chapter 84 and is an automatic data processing machine under Heading 8471; however, the separately imported components do not constitute a complete automatic data processing machine. The Motherboard is expressly described under Tariff Item 8473 30 20. The model-specific Chassis, having no independent tariff description and being suitable solely or principally for the Industrial Computing Platform, is classifiable as an other part of a machine of Heading 8471 under Note 2(b) to Section XVI. The Power Supply Unit converts AC power into regulated DC power and has the essential characteristics of a static converter or rectifier. Since it is independently specified under Heading 8504, Note 2(a) to Section XVI requires classification in that heading rather than as a part under Heading 8473.
Conclusion: The Motherboard is classifiable under Tariff Item 8473 30 20, the Chassis under Tariff Item 8473 30 99, and the Power Supply Unit under Tariff Item 8504 40 29 of the First Schedule to the Customs Tariff Act, 1975.
Issue (ii): Applicability of BIS certification requirements to the Power Supply Unit.
Analysis: A Power Supply Unit classified under Tariff Item 8504 40 29 falls within CTH 8504.40. Serial No. 18 of the First Schedule to the Machinery and Electrical Equipment Safety (Omnibus Technical Regulation) Order, 2024 covers power semiconductor converters and their assemblies, sub-assemblies and components under that tariff heading.
Conclusion: The Power Supply Unit is subject to the applicable BIS certification requirements at the time of importation.
Issue (iii): Eligibility of the Power Supply Unit for basic-customs-duty exemption under Serial No. 4 of Notification No. 25/2005-Cus. dated 01.03.2005.
Analysis: Serial No. 4 exempts static converters for automatic data processing machines and their units, excluding static converters for cellular mobile phones. The Power Supply Unit is a static converter intended to provide regulated DC power to the Industrial Computing Platform, which is an automatic data processing machine, and the material does not indicate its use for cellular mobile phones.
Conclusion: The Power Supply Unit is eligible for exemption from basic customs duty under Serial No. 4 of Notification No. 25/2005-Cus. dated 01.03.2005, subject to fulfilment of the prescribed conditions and import-time verification.
Final Conclusion: The ruling determines the tariff treatment, regulatory compliance requirement and duty-exemption eligibility of the proposed imported components according to their respective functions and specific tariff descriptions.
Ratio Decidendi: Under Note 2 to Section XVI, a component independently covered by a specific Chapter 84 or 85 heading is classifiable in that heading, while a component suitable solely or principally for an automatic data processing machine and lacking separate tariff coverage is classifiable as a part of that machine.
