under Customs Tariff Heading 2909.43. The respondents, however, after allowing earlier clearance under Tariff Heading 2909.43 sought to classify the goods under Tariff Hearing 29.05. According to the petitioner, though Ethyl/Butyl Glycol is specifically classifiable under Tariff Heading 2909.43 and this fact is accepted by the respondents, nevertheless the respondents first suggested classification under Tariff Heading 29.05 and later accepted classification under Tariff Heading 2909.43. Notification no.39/90 under which the exemption is granted, Butyl Glycol is wrongly classified under Tariff Heading 29.05. According to the petitioner, the respondents have accepted the typographical error and therefore have been granting duty concession under the notification to several importers under sr. no.8 of the said Notification no.39/90 dated 20th March 1990 as amended by Notification no.60/91 dated 25th July 1991. In spite of the same, the petitioner has been denied the concessional rate of duty under sr. no.8 of the said notification by wrongly classifying it under Tariff Heading 29.05. According to the petitioner, the respondents are refusing the concessional duty at sr. no.8 and are seeking to clear additional duty at sr. no.8 of the same notification.
