Process control classification under tariff law turns on actual function, with limitation defeating duty demand and penalties.

Programmable process controllers used for industrial process control, continuously regulating variables such as pressure, temperature, flow and level, were held to be classifiable under Heading 90.32 rather than Heading 85.37, because the decisive test was the actual function of the goods. Early disclosure of the product catalogue and related details meant there was no suppression or misdeclaration, so the duty demand was time-barred. Once limitation failed, the penalty and confiscation could not survive and consequential penal action was unsustainable.

Issues: (i) whether the programmable controller manufactured by the assessee was classifiable under Heading 85.37 or Heading 90.32 of the Central Excise Tariff Act, 1985; and (ii) whether the demand was barred by limitation and the penalty and confiscation were sustainable.

Issue (i): whether the programmable controller manufactured by the assessee was classifiable under Heading 85.37 or Heading 90.32 of the Central Excise Tariff Act, 1985.

Analysis: The product literature and the departmental description showed that the goods were used for industrial process control by continuously monitoring and maintaining variables such as pressure, temperature, flow and level at the desired values. The Board's clarification distinguished programmable logic controllers used for controlling machines from programmable process controllers used for controlling processes. On the facts, the product matched the characteristics of a programmable process controller and not a machine-control panel falling under Heading 85.37.

Conclusion: The product was classifiable under Heading 90.32 and not under Heading 85.37.

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 related details at an early stage, so there was no basis to infer misdeclaration or suppression. In a classification dispute, differing views on tariff placement do not by themselves establish wilful suppression or intent to evade duty. Once the demand was held time-barred, the penalty and confiscation could not survive.

Conclusion: The demand was time-barred and the penalty and confiscation were unsustainable.

Final Conclusion: The appeal succeeded, the impugned classification under Heading 85.37 was set aside, and the assessee obtained relief on both duty demand and consequential penal action.

Ratio Decidendi: For tariff classification, the decisive test is the actual function of the goods; where the product is a process control apparatus for continuously regulating industrial variables, it falls under Heading 90.32 rather than Heading 85.37.
