Clarificatory exemption notification amendment extended to earlier clearances, covering polystyrene moulding powder under the original exemption.

An Explanation inserted into an exemption notification was held clarificatory where it merely made explicit that "resins" included moulding powders of such resins and did not add any new condition. On that basis, polystyrene moulding powder was treated as covered by the original exemption for polystyrene resins, because moulding powder is a primary form under Chapter 39 and falls within heading 39.03. The clarificatory amendment therefore applied to consignments cleared before its issuance, and the refund claim remained maintainable.

Issues: Whether the amendment inserting an Explanation in Notification No. 133/86-C.E. by Notification No. 239/87-C.E. was clarificatory and could be applied to consignments cleared before the amending notification, so as to extend exemption to polystyrene moulding powder.

Analysis: Notification No. 133/86-C.E. exempted polystyrene resins under sub-heading 3903.10 of the Central Excise Tariff Act, 1985. Notification No. 239/87-C.E. inserted an Explanation stating that the expression "resins" includes moulding powders of such resins. The amendment did not introduce a new condition or alter the scheme of exemption but only made explicit what was already implicit in the original notification. Since Chapter Note 6(a)(ii) to Chapter 39 treats moulding powder as a primary form and heading 39.03 covers polymers of styrene in primary form, polystyrene moulding powder fell within the original exemption itself.

Conclusion: The Explanation was clarificatory and applied to goods cleared before its issue. The refund claim was maintainable, and the assessee succeeded.

Ratio Decidendi: A clarificatory amendment to an exemption notification may apply to earlier clearances where it merely makes explicit a meaning already implicit in the original notification and does not impose any new condition.
