MODVAT credit denied for corrosion inhibitors lacking direct nexus with manufacture; extended limitation also rejected without suppression.

The extended limitation period under central excise law could not be invoked because there was no allegation of suppression, misdeclaration, or misstatement; the demand was therefore time-barred beyond six months, though the demand within six months remained sustainable. Hegatreat and Hegafilm, used as corrosion inhibitors in cooling water and steam generation systems, were not eligible for MODVAT credit because they lacked a direct nexus with the manufacture of synthetic rubber and were used only for machinery protection, not as inputs used in or in relation to manufacture. One appeal succeeded only on limitation and required recomputation, while the other failed on merits.

Issues: (i) Whether the demand in one appeal was barred by limitation beyond the normal period under the central excise law. (ii) Whether Hegatreat and Hegafilm, used as corrosion inhibitors in cooling water and steam generation systems, were eligible inputs for MODVAT credit as being used in or in relation to the manufacture of synthetic rubber.

Issue (i): Whether the demand in one appeal was barred by limitation beyond the normal period under the central excise law.

Analysis: The department had not alleged suppression of facts, misdeclaration, or misstatement so as to justify invocation of the extended period. The authorities were aware of the use of MODVAT credit on the items in question. The notice could therefore sustain the demand only for the normal six-month period and not for the larger period.

Conclusion: The demand beyond the normal period was held to be time-barred, while the demand within six months from the notice was held sustainable.

Issue (ii): Whether Hegatreat and Hegafilm, used as corrosion inhibitors in cooling water and steam generation systems, were eligible inputs for MODVAT credit as being used in or in relation to the manufacture of synthetic rubber.

Analysis: The items were admitted to be used as corrosion inhibitors in the cooling water and steam systems and to protect machinery from corrosion. They were not used as ingredients in the manufacture of synthetic rubber, nor did they directly contribute to the manufacturing process in the manner required for input eligibility. The cited precedents were distinguished because those cases involved materials directly used in or in relation to manufacture.

Conclusion: The items were held not to be eligible inputs for MODVAT credit.

Final Conclusion: One appeal succeeded only to the extent of the limitation issue and was remanded for recomputation, while the other appeal was rejected on merits.

Ratio Decidendi: For MODVAT eligibility, the goods must have a direct nexus with manufacture and mere use as corrosion inhibitors for machinery maintenance does not satisfy the requirement of use in or in relation to the manufacture of the final product; the extended period cannot be invoked absent allegations supporting it.
