Electrical grade insulation paper classification accepted for presspahn paper, securing concessional customs treatment under the notification.

Presspahn paper was treated as electrical grade insulation paper for purposes of Customs Notification No. 37 dated 1-3-1978, because the relevant Indian and British Standards identified presspaper and pressboard for electrical use as insulating paper and covered thickness ranges matching the imported goods. In the absence of any statutory distinction between paper and board in the tariff or notification, the specialised technical standards were preferred over the department's general trade glossary. The imported goods therefore fell within the exempted category under Chapter 48 and qualified for the concessional rate of duty and relief from additional duty under section 3 of the Customs Tariff Act, 1975.

Issues: Whether presspahn paper imported by the appellants was covered by the expression "electrical grade insulation paper" in Customs Notification No. 37 dated 1-3-1978 and was therefore entitled to the concessional rate of duty.

Analysis: The relevant notification exempted condenser tissue paper and electrical grade insulation paper falling within Chapter 48 of the Customs Tariff Act, 1975 from duty in excess of the specified limit and from additional duty under Section 3 of the Customs Tariff Act, 1975. The Tribunal examined the Indian Standards and British Standards dealing specifically with presspaper and pressboard for electrical purposes. Those specifications showed that presspahn paper is an electrical insulating paper and that its thickness could extend within the range of the imported goods. In the absence of any statutory demarcation between paper and board in the tariff or the notification, the Tribunal preferred the specialised technical standards over the general paper-trade glossary relied on by the department.

Conclusion: The imported goods were electrical grade insulation paper and were entitled to the benefit of the notification. The orders denying the concession were unsustainable.
