Rubber solution adhesive classification under Heading 3506 brings exemption, while no-power manufacture claims may be verified conditionally.

Rubber solution used as an adhesive for retreading tyres was treated as a prepared glue or other prepared adhesive under Heading 3506, not under the rubber-solution heading, and the exemption linked to that tariff entry was available. The same classification also brought the product within Notification No. 175/86-C.E. For the water-based rubber solution, entitlement to Notification No. 250/86-C.E. was left to verification of the factual condition that manufacture was undertaken without the aid of power, and that limited remand was maintained. The Revenue challenge accordingly did not disturb either the classification finding or the verification-based exemption approach.

Issues: (i) Whether rubber solution (solvent based) was classifiable under Heading 3506 of the Central Excise Tariff Act, 1985 and entitled to the benefit of Notification No. 175/86-C.E. dated 01.03.1986; (ii) Whether the benefit of Notification No. 250/86-C.E. dated 11.04.1986 in respect of rubber solution (water based) was rightly left to verification on the question whether manufacture was undertaken without the aid of power.

Issue (i): Whether rubber solution (solvent based) was classifiable under Heading 3506 of the Central Excise Tariff Act, 1985 and entitled to the benefit of Notification No. 175/86-C.E. dated 01.03.1986.

Analysis: The product was treated as a prepared adhesive based on rubber solution. The tariff entry for Heading 3506 covered prepared glues and other prepared adhesives, while Heading 40.05 was not considered appropriate in view of the exclusion for rubber solutions and dispersions used as adhesives. The earlier Tribunal view on similar rubber cement supported classification under Heading 3506, and once that classification was accepted, the exemption notification applicable to goods under that heading followed.

Conclusion: The product was correctly classified under Heading 3506 and the benefit of Notification No. 175/86-C.E. was available to the assessee.

Issue (ii): Whether the benefit of Notification No. 250/86-C.E. dated 11.04.1986 in respect of rubber solution (water based) was rightly left to verification on the question whether manufacture was undertaken without the aid of power.

Analysis: The lower appellate authority had not finally granted the exemption outright but had directed verification of the factual assertion that no power was used in manufacture, with the matter left open to the Assistant Collector for examination. No reason was found to interfere with that limited remand/verification direction.

Conclusion: The remand for verification and the conditional extension of the exemption were upheld.

Final Conclusion: The Revenue's challenge failed in full, the classification and exemption finding on the first product was sustained, and the verification-based approach on the second product was also maintained.

Ratio Decidendi: Rubber solution used as an adhesive for retreading tyres is classifiable as prepared glue or adhesive under Heading 3506 rather than under the rubber-solution heading, and an exemption tied to that heading follows; a factual exemption claim depending on absence of power may properly be left for verification.
