Customs exemption applies to additional duty on imported corkwood, but post-clearance invoice reduction does not justify basic duty refund.

Additional duty of customs under Section 3 of the Customs Tariff Act is computed by reference to the excise duty leviable on like goods, so an exemption notification issued under the Central Excise Rules could be applied to imported corkwood; the contrary view that only a customs exemption under Section 25(1) could operate was rejected. The imported corkwood also met the condition of being manufactured or produced without the aid of power, as the record showed manual stripping and no power use, so the exemption was available. A post-clearance reduction in invoice value did not, by itself, establish entitlement to refund of basic customs duty because the statutory requirements for damage or deterioration were not shown.

Issues: (i) Whether an exemption notification issued under Rule 8(1) of the Central Excise Rules, 1944 applied to additional duty of customs leviable under Section 3 of the Customs Tariff Act, 1975 on imported corkwood; (ii) whether the imported corkwood satisfied the condition of being manufactured or produced without the aid of power so as to attract Notification No. 179/77 dated 18-6-1977; and (iii) whether reduction in invoice value after clearance from customs control entitled the importers to refund of basic customs duty.

Issue (i): Whether an exemption notification issued under Rule 8(1) of the Central Excise Rules, 1944 applied to additional duty of customs leviable under Section 3 of the Customs Tariff Act, 1975 on imported corkwood.

Analysis: Additional duty under Section 3 is equal to the excise duty for the time being leviable on a like article if produced or manufactured in India. The exemption notification issued under the Central Excise Rules was therefore relevant to the computation of additional duty. The prior special bench view accepted that excise exemption notifications could govern liability to additional duty on imported goods.

Conclusion: The notification was applicable, and the contention that only a customs exemption under Section 25(1) of the Customs Act, 1962 could apply was rejected.

Issue (ii): Whether the imported corkwood satisfied the condition of being manufactured or produced without the aid of power so as to attract Notification No. 179/77 dated 18-6-1977.

Analysis: The record showed that cork is removed manually from the oak tree by axe, with supporting literature and certificate indicating manual stripping and no use of power in the production process. The contrary inference drawn by the appellate authority was unsupported by adequate evidence. On the materials before the Tribunal, the goods fell within the notification's condition of non-use of power.

Conclusion: The imported corkwood satisfied the condition of manufacture or production without the aid of power, and the exemption was available.

Issue (iii): Whether reduction in invoice value after clearance from customs control entitled the importers to refund of basic customs duty.

Analysis: Section 22 of the Customs Act, 1962 permits abatement where there is damage or deterioration within the statutory period and in the prescribed circumstances. The claim was not shown to arise from damage or deterioration within Section 22; instead, it was based on a post-clearance complaint that the goods were under-grade, with no satisfactory material explaining the basis of the reduced value or the contractual specification. The reduced invoice value alone was insufficient to justify refund of basic duty.

Conclusion: The claim for refund of basic customs duty was not established and was rejected.

Final Conclusion: The importers were entitled to relief from additional duty of customs on the imported corkwood, but not to refund of basic customs duty on the ground of reduced value.

Ratio Decidendi: For additional duty under Section 3 of the Customs Tariff Act, 1975, exemption notifications issued under the corresponding central excise law can be applied, and a post-clearance reduction in invoice value does not by itself justify abatement of basic customs duty unless the statutory conditions for damage or deterioration are satisfied.
