Strict construction of exemption notifications bars retrospective benefit where an amendment enlarges, rather than clarifies, the exempted goods.

L-Lysine Mono Hydrochloride (Feed Grade) imported before the amendment was not covered by Notification No. 40/89-Cus., because the unamended exemption had to be applied strictly on its express terms. The later Notification No. 223/89-Cus. was not merely clarificatory; its explanatory note showed a conscious enlargement of the exempted goods by adding two more chemicals. Technical material also treated L-Lysine and L-Lysine Mono Hydrochloride as distinct chemicals. On that basis, the amendment could not retrospectively extend exemption to goods not specifically included earlier, and the denial of exemption was upheld.

Issues: Whether L-Lysine Mono Hydrochloride (Feed Grade) imported prior to the amendment was covered by Notification No. 40/89-Cus. dated 01.03.1989, and whether the subsequent Notification No. 223/89-Cus. dated 14.06.1989 was merely clarificatory.

Analysis: The relevant entry inward was granted before the amending notification, so the unamended exemption notification governed the import. The explanatory note to the amendment stated that it had the effect of including two more chemicals, showing a conscious enlargement of the exemption and not a mere clarification of an existing ambiguity. Technical material also indicated that L-Lysine and L-Lysine Mono Hydrochloride were distinct chemicals, the latter being a salt derived from the former. In these circumstances, the Chemical Examiner's view could not override the expressed scope and purpose of the amendment as issued by the competent authority. Exemption notifications are to be construed strictly according to their clear terms.

Conclusion: The imported goods were not entitled to exemption under the unamended notification, and the amendment was not clarificatory. The denial of exemption was upheld.

Ratio Decidendi: An exemption notification must be construed strictly, and where an amending notification expressly adds goods to the exempted category, the amendment is enlarging in nature and does not retrospectively cover goods not specifically included earlier.
