HEADNOTE: The appellant are the manufacturers of Injection Mould- ing Machines and their 19 types of parts, one of which is called 'Tie Bar Nuts' which are stated to be used to fix the platens in correct distances in between tie bars. The appel- lants submitted their classification lists for the year Plasmac Machine Manufacturing Co. ... vs Collector Of Central Excise, Bombay on 27 November, 1990  1 1981-82 and listed the machines as also the Tie Bar Nuts under Tariff item No. 68. The Superintendent, Central Ex- cise, by his letter dated 20.10.81 forwarded the classifica- tion list and directed the appellants to file a separate classification list for the Tie Bar Nuts under tariff item No. 52, take out licence for the same and also to furnish value and clearance of Tie Bar nuts for the year 1980-81 and 1981-82. Aggrieved the appellants appealed to the Collector of Central Excise (Appeal) Bombay, who, while allowing the ï7 3 Item No. 68. He took the view that the nuts in question were not available in the market and were designed for a particu- lar purpose for Injection Moulding Machines and could not be used for any other purpose. Thereupon the Department pre- ferred appeal to the Central Custom. Excise and Gold Control Tribunal, New Delhi and contended before the Tribunal that the sample of the product showed that it was a plain nut and no special features were apparent and the main function of the Tie Bar Nuts was to fasten. The Tribunal allowed the appeal holding that the Tie Bar Nuts would merit classifica- tion under Tariff Item No. 52. The appellants have thus filed this appeal under section 35L of the Central Excise and Salt Act, 1944. Dismissing the appeal, this Court, HELD: If according to law Tie Bar Nuts fall within tariff Item 52, the fact that department earlier approved their classification under tariff item 68 will not stop it from revising that classification to one under item 52. There could be no estoppel against a statute. [387F-G] If an article is classifiable under a specific Item, it would be 385 against the very principle of classification to deny it the proper percentage and consign it to the residuary item. [391D] There is no dispute that Tie Bar Nuts conform to the popular idea of nuts. [390H] The 'Tie Bar Nuts' function of fixing the platens as stated by the appellants and that of factening, as argued by them, are not basically different, and the appellants them- selves having called the goods as 'nuts' we are of the view that the Tribunal is correct in classifying Tie Bar Nuts under Tariff Item 52. There is therefore, no reason to interfere with the department's order and no justification for classifying those in the residuary item 68. [391C] M/s. Elson Machines Pvt. Ltd. v.
