EV combo power-conversion unit imports: components not treated as "parts" under Heading 8504; separately classified; confidentiality granted

Whether components imported for manufacture of a combo power-conversion unit for electric vehicles were classifiable as "parts" of the unit under Heading 8504 was determined by applying GRI 1, Section Note 2(a) to Section XVI, and relevant HSN Explanatory Notes. Since each item was covered by a specific tariff heading, they could not be classified as parts of the composite equipment merely due to intended end-use; they required independent classification under their respective headings. Accordingly, copper cables were classified under 8544; capacitors under 8532; ceramic gap pads under 8547; connectors, fuses and relays under 8536; inductors and transformers under 8504; and MOSFETs/transistors under 8541; confidentiality protection was granted.

Issues: (i) Whether the goods proposed to be imported (Copper cables; Capacitor; Ceramic gap pad; Connector; Fuse; Relay; Inductor; MOSFET/Transistor; Transformer) are to be classified under their respective tariff headings as listed in Table-II of the ruling or as parts of the Combo 3-in-1 (OBC+DC/DC+PDU) (classifiable under heading 8504).

Analysis: The Authority applied the General Rules of Interpretation (GRI), relevant Chapter and Section Notes of the First Schedule to the Customs Tariff Act, 1975 and the HSN Explanatory Notes. Note 2 to Section XVI and its sub-parts (notably Note 2(a)) provide that parts which constitute goods included in any heading of Chapter 84 or 85 must be classified in their respective headings. The HSN Explanatory Notes to Section XVI and to the relevant headings confirm that articles which independently constitute entries in Chapter 85 (or 84/85) are to be classified in those specific headings even if designed to be used as part of a particular machine. The Authority also considered Note 2 to Section XVII and the three HSN conditions for vehicle parts, concluding those conditions are not satisfied because the items are specifically and more precisely included elsewhere and are not exclusively for motor vehicles. Applying these principles item-wise, the Authority examined the nature and technical characteristics of each product and identified the specific tariff sub-headings (e.g., insulated copper conductors under 8544; electrical capacitors under 8532; insulating ceramic fittings under 8547; plugs/sockets/connectors/fuses/relays under 8535/8536 as per voltage ratings; inductors and transformers under 8504; semiconductor devices under 8541), relying on the specific tariff entries and HSN explanatory guidance to determine the appropriate sub-items where applicable.

Conclusion: The Authority concluded that each of the listed products is classifiable on its own merit under the specific tariff headings shown in Table-II (Copper Cables 8544; Capacitor 8532; Ceramic gap pad 8547; Connector 8535/8536 depending on voltage; Fuse 8536; Relay 8536; Inductor 8504; MOSFET/Transistor 8541; Transformer 8504 with sub-items by kVA). The items are not to be classified as parts of the Combo 3-in-1 (OBC+DC/DC+PDU).

Ratio Decidendi: Where an imported article independently corresponds to a specific heading of Chapter 84 or 85, it must be classified in that specific heading (Note 2(a), Section XVI and attendant HSN Explanatory Notes), and not as a part of another machine even if intended for use in that machine.
