Process control equipment classification under Heading 90.32 prevailed, with limitation and consequential penalty also failing.

Programmable controllers used for industrial process control were held classifiable under Heading 90.32, because their essential function was continuous monitoring and regulation of process variables such as pressure, temperature, flow and level, rather than mere machine or electrical control. The extended period of limitation was found unavailable where the product literature and functional details had been disclosed, so the dispute rested on classification of known facts and showed no suppression or wilful misstatement. On that basis, the demand was time-barred and the penalty and confiscation could not stand.

Issues: (i) Whether programmable controllers used for industrial process control were classifiable under Heading 90.32 of the Central Excise Tariff Act, 1985 or under Heading 85.37; (ii) Whether the demand was barred by limitation and the penalty and confiscation were sustainable.

Issue (i): Whether programmable controllers used for industrial process control were classifiable under Heading 90.32 of the Central Excise Tariff Act, 1985 or under Heading 85.37.

Analysis: The product literature and the departmental description showed that the equipment continuously monitored and regulated variables such as pressure, temperature, flow and level in industrial plants. Its essential function was regulatory control of processes, not merely control of machines or electrical distribution. Applying the Board's 37B clarification and the functional test recognised in the later authorities relied upon, the product answered the description of programmable process controller and not programmable logic controller for Heading 85.37.

Conclusion: The product was classifiable under Heading 90.32 and not under Heading 85.37, in favour of the assessee.

Issue (ii): Whether the demand was barred by limitation and the penalty and confiscation were sustainable.

Analysis: The assessee had disclosed the product catalogue and functional details at an early stage. The dispute was one of classification on disclosed facts, and no material justified invocation of the extended period on the basis of suppression or wilful misstatement. Once the demand itself failed on limitation, the penalty and confiscation based on the same foundation could not survive.

Conclusion: The demand was time-barred and the penalty and confiscation were unsustainable, in favour of the assessee.

Final Conclusion: The classification adopted by the Commissioner was set aside, the goods were held to fall under Heading 90.32, and the consequential duty, penalty and confiscation were quashed.

Ratio Decidendi: Goods whose essential and disclosed function is continuous monitoring and regulation of industrial process variables are classifiable as process control equipment under Heading 90.32, and where the classification dispute is based on facts fully disclosed to the department, the extended period cannot be invoked absent suppression or wilful misstatement.
