2003 (8) TMI 397 - AT - Central Excise

Issues Involved: Classification of Heavy Petroleum Stock (HPS) as Residuary Fuel Oil (RFO) and eligibility for concessional duty under specific notifications.

Issue-wise Detailed Analysis:

1. Classification of HPS as RFO:
The primary issue was whether HPS, derived from refining crude petroleum, could be classified as RFO. The appellants contended that HPS, a leftover from crude petroleum distillation, should fall under Tariff Item 11A(4) and be classified as RFO. They argued that HPS is a residuary product distinct from other products listed under sub-items (1) to (3) of Item 11A. They supported their argument with technical definitions from various authoritative sources, which describe residual fuel oils as leftover products from refining processes. The Tribunal acknowledged that HPS is indeed a residue of petroleum oils and a type of fuel oil, thus meeting the criteria for being termed as RFO.

2. Eligibility for Concessional Duty:
The appellants argued that HPS should be eligible for concessional duty under Notification No. 160/83-C.E., dated 24-5-1983, which provides partial exemption specifically to RFO. They referred to a clarification from the Central Board of Excise & Customs, which stated that the term "Residual Fuel Oil" includes all types of viscous residuums obtained after removing volatile components from crude petroleum. The Tribunal noted that the Board's clarification supported the inclusion of HPS within the ambit of RFO, thus making it eligible for the concessional duty.

3. Distinction Between HPS and RFO in Notifications:
The respondent argued that HPS and RFO are distinct products, as evidenced by their separate mention in Notification No. 75/84-C.E., dated 1-3-1984. The notification specified different duty rates for RFO and HPS, with HPS attracting nil duty when intended for use as feedstock in fertilizer manufacture. The Tribunal, however, found that this distinction did not imply that HPS is not a residual fuel oil. Instead, it indicated that HPS, as a type of residual fuel oil, could attract different duty rates based on its intended use.

4. Technical Definitions and Industry Standards:
The Tribunal relied on various technical books and industry standards to conclude that residual fuel oils are products left over after refining crude petroleum. Definitions from sources like Van Nostrand's Scientific Encyclopaedia, Hawley's Condensed Chemical Dictionary, and the Illustrated Petroleum Reference Dictionary consistently described residual fuel oils as leftover products from refining processes. The Tribunal found that HPS, being a residue from crude petroleum refining, fits these definitions and should be classified as RFO.

5. Board's Clarification and Interpretation of Exemption Notification:
The Tribunal emphasized that the Board's clarification in D.O.F. No. 189/7/83-CX.3, dated 5-12-1983, supported the classification of HPS as RFO. The Board had stated that the term "Residual Fuel Oil" is broad enough to include all types of viscous residuums from crude petroleum. The Tribunal also noted that the interpretation of exemption notifications should be strict, but the appellants had demonstrated that HPS is essentially RFO, thus qualifying for the concessional duty.

Conclusion:
The Tribunal concluded that HPS is a type of residual fuel oil and should be classified as RFO. Consequently, HPS is eligible for the concessional duty under the relevant notifications. The Tribunal set aside the impugned order and allowed all the appeals, affirming that HPS falls within the ambit of RFO and qualifies for the concessional duty rates specified in the notifications.
