Tariff classification confirmed for inverter assemblies under the inverter heading; concessional BCD allowed subject to origin compliance.

The document determines that the imported inverter assembly is classifiable under tariff heading 8504 40 10 because its principal function-converting DC to AC-is captured by the specific inverter description and supported by GRI, HSN explanatory notes, and chapter/section notes; consequently, the assembly qualifies for concessional Basic Customs Duty under the concessional notification covering 8504 40, and it also qualifies under the Japan CEPA concession subject to compliance with the prescribed origin rules. The ruling thus links specific-function classification to entitlement to the stated tariff concessions, conditional on origin compliance for Japan imports.

Issues: (i) Whether the imported "Inverter Assembly" is classifiable under Customs Tariff Heading 8504 40 10 of the First Schedule to the Customs Tariff Act, 1975; (ii) Whether the applicant is eligible to avail concessional Basic Customs Duty under Sl. No. 13 of Notification No. 57/2017-Customs dated 30.06.2017 (as amended) on import of the subject goods; (iii) Whether the applicant is eligible to avail concessional Basic Customs Duty under Sl. No. 646 of Notification No. 69/2011-Customs dated 29.07.2011 on import of the subject goods when imported from Japan.

Issue (i): Whether the "Inverter Assembly" is classifiable under CTH 8504 40 10.

Analysis: Classification is governed by the General Rules of Interpretation and relevant Section/Chapter notes and HSN explanatory notes. CTH 8504 covers electrical static converters and expressly includes inverters converting direct current to alternating current. Section Note 2(a) to Section XVI and Note 2(f) to Section XVII exclude electrical machinery of Chapter 85 from being treated as parts of Chapter 87. Rule 6 and Rule 3(a) of the GRI guide sub-heading/tariff entry classification and preference for specific entries over residual entries. The recorded findings establish that the subject good performs the principal function of converting DC to AC and vice versa and therefore falls within the description of electric inverter in CTH 8504 40 10.

Conclusion: The "Inverter Assembly" is classifiable under Customs Tariff Heading 8504 40 10.

Issue (ii): Whether the applicant is eligible for concessional BCD under Sl. No. 13 of Notification No. 57/2017-Customs dated 30.06.2017.

Analysis: Sl. No. 13 of Notification No. 57/2017-Customs grants concessional BCD to goods falling under CTH 8504 40 except specified exclusions (charger, power adapter, solar inverter). Having held that the subject goods are classifiable under CTH 8504 40 10 and are not within the specified exclusions, the notification applies.

Conclusion: The applicant is eligible to avail concessional Basic Customs Duty under Sl. No. 13 of Notification No. 57/2017-Customs dated 30.06.2017.

Issue (iii): Whether the applicant is eligible for concessional BCD under Sl. No. 646 of Notification No. 69/2011-Customs dated 29.07.2011 when imported from Japan.

Analysis: Sl. No. 646 of Notification No. 69/2011-Customs exempts goods under CTH 8504 40 from BCD when originating in Japan and when origin rules under the CEPA with Japan are complied with. The subject goods fall under CTH 8504 40 10; eligibility under the notification is therefore contingent on satisfaction of the origin criteria.

Conclusion: The applicant is eligible to avail concessional Basic Customs Duty under Sl. No. 646 of Notification No. 69/2011-Customs dated 29.07.2011 for imports originating in Japan and satisfying the applicable origin rules.

Final Conclusion: The advance ruling answers the questions in favour of the applicant: the subject "Inverter Assembly" is classifiable under CTH 8504 40 10, the applicant is eligible for the concessional BCD under Sl. No. 13 of Notification No. 57/2017-Customs, and eligible for concessional BCD under Sl. No. 646 of Notification No. 69/2011-Customs when origin conditions from Japan are met.

Ratio Decidendi: Where a product's principal function corresponds to a specific tariff entry and is supported by HSN explanatory notes and chapter/section notes, that specific tariff entry (here CTH 8504 40 10) governs classification and consequent application of concessional notifications subject to their stated conditions.
