Densified wood classification and limitation on excise demand turn on treatment effects and absence of suppression.
Chemical pressure impregnation and seasoning of timber was treated as producing "densified wood" under Chapter Note 2 of Chapter 44 because the process resulted in increased density, hardness, strength and resistance as contemplated by the tariff definition; the classification was upheld in favour of Revenue. The extended limitation period, however, could not be invoked because the record showed disclosure of the manufacturing process and no sufficient proof of suppression of facts or misstatement with intent to evade duty; the demand beyond the normal period was unsustainable in favour of the assessee. The matter required fresh quantification for the surviving period.
Issues: (i) whether timber treated by chemical pressure impregnation and seasoning answered the description of "densified wood" under Chapter Note 2 of Chapter 44 of the Central Excise Tariff Act, 1985; (ii) whether the demand could be sustained for the extended period in the absence of suppression or misstatement of facts.
Issue (i): whether timber treated by chemical pressure impregnation and seasoning answered the description of "densified wood" under Chapter Note 2 of Chapter 44 of the Central Excise Tariff Act, 1985.
Analysis: The statutory definition covered wood subjected to chemical or physical treatment which thereby acquired increased density or hardness together with improved mechanical strength or resistance to chemical or electrical agencies. The test reports showed that the treated samples, as compared with untreated counterparts, exhibited increased density in some cases, increased hardness in most samples, and increased strength in all samples. The commercial literature of the manufacturer also indicated improved strength and electrical resistance. Mere preservative treatment would not by itself alter classification, but the material on record showed that the process produced the characteristics contemplated by the chapter note.
Conclusion: The treated wood was correctly held to fall within "densified wood", in favour of Revenue.
Issue (ii): whether the demand could be sustained for the extended period in the absence of suppression or misstatement of facts.
Analysis: The record showed prior disclosure of the manufacturing process to the department and earlier proceedings dating back to 1978, with no sufficient basis to establish suppression of facts or misstatement with intent to evade duty. In the absence of the ingredients required for the extended period, the larger limitation could not be invoked.
Conclusion: The extended period demand was unsustainable, in favour of the assessee.
Final Conclusion: The classification issue was decided against the assessee, but the demand could not be upheld beyond the normal period of limitation, and the matter required fresh quantification for the surviving period.
Ratio Decidendi: Where chemical or physical treatment of wood results in increased density, hardness, strength, or resistance as contemplated by the tariff definition, the product is classifiable as densified wood; the extended limitation period cannot be invoked without proof of suppression or misstatement with intent to evade duty.
