The Tribunal upheld the classification of rough ophthalmic glass blanks under item No. 23A(4) of the Central Excise Tariff Schedule, setting aside the Appellate Collector's order and restoring the Assistant Collector's decision. The dispute revolved around the correct classification for the levy of additional duty of customs, with the Tribunal determining that rough blanks do not fall under the category of glassware but rather under "other glass."

Issues:
1. Correct classification of ophthalmic glass blanks under Central Excise Tariff Schedule for levy of additional duty of customs.
2. Review of the Appellate Collector's order by the Central Government.
3. Challenge on the ground of limitation regarding the show cause notice.
4. Classification of rough ophthalmic glass blanks under item No. 23A(4) of the CET.

Analysis:
1. The appeal concerns the classification of ophthalmic glass blanks for the levy of additional duty of customs under the Central Excise Tariff Schedule. The dispute arose from the amendment of item No. 23A(4) on 1-3-1979, changing it from "other glassware including tableware" to "other glass and glassware including tableware." The importer's claim for refund of additional duty was rejected by the Assistant Collector, but the Appellate Collector determined the correct classification under item No. 68 CET. The Appellate Collector's reasoning emphasized that rough ophthalmic glass blanks do not fall under the category of "other glass" or "glassware including tableware" but rather under item No. 68.

2. The Central Government issued a show cause notice to review the Appellate Collector's order, contending that rough blanks should be classified under item No. 23A(4) of the CET as glassware. The respondents challenged this notice on the grounds of limitation, citing that the notice was issued after the prescribed timeline under Section 131(4)(b) of the Customs Act. However, it was clarified that the limitation provision did not apply to the impugned order, which did not involve penalties or confiscation.

3. The respondents supported the Appellate Collector's reasoning that rough glass blanks are specific pieces made from optical quality glass and are not equivalent to unrolled or primary glass. They argued that rough blanks do not qualify as glassware or tableware. The contention that rough blanks are glassware was refuted based on legal interpretations by the High Court and the Supreme Court, defining glassware as specific articles like sheet glass or glass tumblers.

4. The Tribunal analyzed the Supreme Court's judgment on glass mirrors to determine the classification of rough ophthalmic glass blanks. The Court's emphasis on the functional character of the mirror, derived from processes applied to the glass medium, was considered. It was concluded that rough blanks, being semi-finished articles of optical quality, do not qualify as glassware but can be classified as "other glass" under item No. 23A(4) of the CET. The Tribunal upheld the classification of rough ophthalmic glass blanks under item No. 23A(4) and set aside the Appellate Collector's order, restoring the Assistant Collector's decision.
