Classification of cracked naphtha products and duty limitation under Section 11-A: normal period applies, exemption denied.

Limitation for recovery of short-levied or non-levied duty is governed by Section 11-A, and prior approval of a classification list does not bar a demand within the normal six-month period. The extended period applies only on proof of fraud, collusion, wilful mis-statement or suppression of facts; on the facts, no such element was established, so the demand could not go beyond six months. For classification, ethylene, propylene and butadiene obtained by cracking raw naphtha were not the immediate result of refining crude petroleum and therefore fell under Tariff Item 68, not Tariff Item 11-AA(2). Once so classified, Notification No. 276/67-C.E. was unavailable.

Issues: (i) whether, even after an approved classification list, duty demand could be raised under the limitation regime of Section 11-A for the normal period of six months or the extended period in cases of fraud, collusion, wilful mis-statement or suppression of facts; (ii) whether ethylene, propylene and butadiene obtained by cracking raw naptha in a declared refinery were classifiable under Tariff Item 11-AA(2) or under Tariff Item 68, and whether Notification No. 276/67-C.E. was available.

Issue (i): whether, even after an approved classification list, duty demand could be raised under the limitation regime of Section 11-A for the normal period of six months or the extended period in cases of fraud, collusion, wilful mis-statement or suppression of facts

Analysis: The limitation for recovery of short-levied or non-levied duty was held to be governed by Section 11-A. The prior approval of a classification list did not bar a demand for the normal period. The extended period was available only where the statutory conditions of fraud, collusion, wilful mis-statement or suppression of facts were established. On the facts, no such case was made out by the Department, and the demand could not extend beyond six months preceding the notice.

Conclusion: The demand was confined to the normal period of six months and not to the extended period.

Issue (ii): whether ethylene, propylene and butadiene obtained by cracking raw naptha in a declared refinery were classifiable under Tariff Item 11-AA(2) or under Tariff Item 68, and whether Notification No. 276/67-C.E. was available

Analysis: The governing test was whether the goods were the immediate result of refining of crude petroleum. The earlier judicial interpretation of the tariff expression "derived from refining of crude petroleum" was treated as controlling, and on that basis goods obtained only after an intermediate process on raw naptha were held not to satisfy Tariff Item 11-AA(2). Since the disputed products were not directly derived from crude petroleum, they fell under Tariff Item 68. Once so classified, the exemption under Notification No. 276/67-C.E. was not attracted.

Conclusion: The products were classifiable under Tariff Item 68 and not under Tariff Item 11-AA(2), and the exemption was not admissible.

Final Conclusion: The Revenue succeeded on the classification issue, while the duty demand was sustained only to the extent permitted by the limitation rule applied to the facts.

Ratio Decidendi: For classification under the relevant tariff entry, the goods must be the immediate result of refining of crude petroleum, and approved classification does not extinguish the Department's right to demand duty within the statutory limitation period.
