Tariff classification of silicone sealants followed their essential characteristics, confirming filler or mastic treatment over adhesives.

Tariff classification of RVT Silicone Sealants turned on their essential characteristics and technical evidence. The Chemical Examiner's report showed a substantial filler content and no binding properties typical of adhesives, so the goods were correctly classified under sub-heading 3214.00 as fillers or mastics rather than adhesives. The department's later own classification of the same goods under Chapter 32 supported that view. On these facts, the lower appellate classification was upheld, and the differential duty demand and penalty did not survive.

Issues: Whether "RVT Silicone Sealants" were correctly classifiable under sub-heading 3214.00 as fillers or mastics, and not as adhesives, with consequential effect on the demand of differential duty and penalty.

Analysis: The lower appellate authority relied on the Chemical Examiner's report indicating that the product contained a substantial percentage of fillers and did not possess binding properties characteristic of adhesives. The record also showed that, for the period subsequent to the dispute, the department itself had been classifying the goods under Chapter Heading 32. On these facts, there was no reason to disturb the classification adopted by the lower appellate authority.

Conclusion: The goods were not to be treated as adhesives for the purpose of the disputed demand. The classification under sub-heading 3214.00 was upheld, and the demand of differential duty and the penalty did not survive.

Ratio Decidendi: Tariff classification must follow the goods' essential characteristics and accepted technical evidence, and where the product lacks adhesive binding properties, it cannot be classified as an adhesive merely on the department's contrary view.
