Classification of mobile telescopic towers follows essential character as special purpose motor vehicles, with exemption tied to prior duty payment.

Mobile telescopic towers cleared as complete units mounted on chassis or trailers were treated as special purpose motor vehicles under Heading 8705, because classification follows the goods' essential character and the form in which they are cleared, not an earlier self-assessment under a different heading. The exemption under Notification No. 6/2006-CE depended on proof that duty had already been paid on the chassis and equipment, so the condition required verification. If the condition was not met, valuation had to be redetermined, including the value of free-supplied chassis where applicable; where chassis were purchased and duty had already been discharged, no further dispute arose.

Issues: (i) Whether the mobile telescopic towers mounted on chassis or trailers were classifiable under Heading 8705 as special purpose motor vehicles or under Heading 7308 as fabricated steel structures; (ii) whether the assessee was entitled to the benefit of Notification No. 6/2006-CE dated 01/03/2006 and, failing that, how the value of free-supplied chassis was to be treated for duty purposes.

Issue (i): Whether the mobile telescopic towers mounted on chassis or trailers were classifiable under Heading 8705 as special purpose motor vehicles or under Heading 7308 as fabricated steel structures.

Analysis: The goods cleared from the factory were complete units consisting of chassis or trailers fitted with mobile telescopic towers. Their essential character was that of motor vehicles fitted with a special superstructure, not isolated fabricated steel structures. Classification had to follow the form in which the goods were cleared, and the lower authority erred in treating them as Heading 7308 goods merely because the assessee had earlier adopted that heading and the show cause notice had not proposed reclassification.

Conclusion: The goods were held classifiable under Heading 8705 as special purpose motor vehicles, not under Heading 7308.

Issue (ii): Whether the assessee was entitled to the benefit of Notification No. 6/2006-CE dated 01/03/2006 and, failing that, how the value of free-supplied chassis was to be treated for duty purposes.

Analysis: The exemption under the notification was subject to the condition that duty on the chassis and equipment had already been paid. As the authority below had not recorded a clear finding on satisfaction of that condition, the matter required verification. If the condition was satisfied, the nil-rate benefit would follow. If not, valuation would have to be redetermined, and in cases where chassis were supplied free of cost, their value would be included for duty computation. Where chassis were purchased by the assessee and duty had already been discharged on the gross value, no dispute survived.

Conclusion: The matter was remanded for limited verification of the exemption condition, and if the condition was not met, for fresh valuation in accordance with law.

Final Conclusion: The assessee succeeded on the classification issue, and the remaining question was confined to verification of the notification condition and consequential valuation.

Ratio Decidendi: Goods must be classified according to their essential character and the form in which they are cleared, and exemption conditioned on prior duty payment can be granted only upon satisfaction of the prescribed condition.
