Multifunctional relay-based equipment falls under heading 8537, and a relay-only exemption does not apply; one demand was time-barred.

Imported relay-based products were held classifiable under CTH 8537, because technical literature, catalogues and expert opinion showed they operated as integrated multifunctional systems performing protection, control, monitoring, metering, communication and programmable logic functions, rather than as simple relays under CTH 8536 49 00. The exemption in Notification No. 21/2002-Cus. was unavailable because it was confined to relays with contact rating up to 7 amperes and the goods were not simpliciter relays. For the GE India matter, prior departmental awareness and an earlier classification decision on similar goods meant the extended limitation period was not satisfied, so the demand was time-barred.

Issues: (i) Whether the imported relay-based products were classifiable under CTH 8536 49 00 as relays or under CTH 8537 as multifunctional electrical apparatus. (ii) Whether the benefit of Notification No. 21/2002-Cus. dated 01.03.2002 was available and whether the demand in the GE India matter was barred by limitation.

Issue (i): Whether the imported relay-based products were classifiable under CTH 8536 49 00 as relays or under CTH 8537 as multifunctional electrical apparatus.

Analysis: Heading 8536 covers electrical apparatus for switching or protecting electrical circuits, including relays, whereas heading 8537 covers boards, panels, consoles and similar assemblies equipped with two or more apparatus of heading 8535 or 8536, including numerical control apparatus and programmable controllers. The imported goods, on the evidence of catalogues, technical literature and expert opinions, were found to perform protection, control, monitoring, metering, communication and programmable logic functions as integrated systems. They were therefore not simple relays but multifunctional equipment falling within heading 8537.

Conclusion: The products were correctly classified under CTH 8537 and not under CTH 8536 49 00.

Issue (ii): Whether the benefit of Notification No. 21/2002-Cus. dated 01.03.2002 was available and whether the demand in the GE India matter was barred by limitation.

Analysis: The exemption under List 26 of the notification was confined to relays of contact rating up to 7 amperes. Since the goods were held to be classifiable under CTH 8537 and not as simpliciter relays, the exemption was unavailable. In the GE India matter, the record showed prior departmental awareness and an earlier classification decision on similar goods, so the ingredients for invoking the extended period were not established and the demand could not survive on limitation.

Conclusion: The exemption was not available. The GE India demand was time-barred and the appeal was allowed, while the ABB appeals failed on merits.

Final Conclusion: The judgment upheld classification under heading 8537 for the ABB appeals, but granted relief to GE India on limitation, resulting in a mixed outcome with the common classification issue decided against the appellants and the demand against GE India set aside.

Ratio Decidendi: Where imported goods, though relay-based, are shown by their technical features to function as integrated multifunctional systems performing protection, control, monitoring and programmable logic, they are classifiable according to their principal commercial and technical character as numerical control apparatus under heading 8537, and an exemption confined to relays does not apply.
