Special purpose vehicle classification and limitation: disclosed chassis use defeated suppression, making the duty demand time-barred.

The Bulk Mix Delivery System was found classifiable as a special purpose motor vehicle under Heading 87.05, not as a machine under Heading 84.79, because it was built on a chassis with tanks, pumps, valves and other assemblies for field use and transport to blasting sites. On limitation, the extended period was held unavailable because the assessee's declarations disclosed use of a motor vehicle chassis and the department had knowledge of the relevant facts; suppression with intent to evade duty was not established. The duty demand and penalty were therefore treated as time-barred, even though the merits finding was adverse to the assessee.

Issues: (i) Whether the Bulk Mix Delivery System was classifiable under Heading 84.79 or Heading 87.05 of the Central Excise Tariff. (ii) Whether the demand of duty and penalty were barred by limitation on the ground that the extended period could not be invoked.

Issue (i): Whether the Bulk Mix Delivery System was classifiable under Heading 84.79 or Heading 87.05 of the Central Excise Tariff.

Analysis: The product was manufactured by fabricating tanks, hopper, piping, pumps, valves, instruments and other mechanical assemblies on a base frame fixed on a chassis so that it could move to the field and carry the prepared mixture to the blasting site. Heading 84.79 applies to machines and mechanical appliances having individual functions not specified elsewhere, whereas Heading 87.05 covers special purpose motor vehicles designed to perform non-transport functions. On the admitted manufacturing process and the HSN explanatory notes, the assembled system was a special purpose motor vehicle and not a machine classifiable under Heading 84.79. The exclusion for self-propelled wheeled machines with specially designed chassis did not apply because the chassis used was not a special chassis.

Conclusion: The product was held classifiable under Heading 87.05 and not under Heading 84.79.

Issue (ii): Whether the demand of duty and penalty were barred by limitation on the ground that the extended period could not be invoked.

Analysis: The classification declaration merely described the product as BMDS under Heading 8479.10, but the Modvat declaration expressly disclosed that motor vehicle chassis was being used as an input for manufacture of BMDS. The department had also defaced the chassis invoice on which Modvat credit was taken. In these circumstances, suppression of facts with intent to evade duty was not established. As the notice covered a period beyond the normal six months, and no valid ground for invoking the extended period existed, the demand was time-barred. Once the demand failed on limitation, the penalty could not survive.

Conclusion: The extended period of limitation was held not invocable and the demand and penalty were set aside as time-barred.

Final Conclusion: The appeal succeeded on limitation, resulting in deletion of the duty demand and penalty, although the classification finding on merits was adverse to the assessee.

Ratio Decidendi: Where the assessee has disclosed the use of chassis in the manufacture of the final product through its declarations, suppression of facts cannot be presumed and the extended period of limitation is not available.
