Prospective reopening of excise classification and residuary tariff classification applied to hair preparation concentrate.

An approved excise classification list may be reopened and modified prospectively after notice and hearing, because an assessee cannot claim estoppel against the correct application of law and natural justice is satisfied by prior opportunity to respond. On classification, M-37 was held to fall within Chapter 33 as a preparation for use on hair, but not within the specific entry for perfumed hair oil under Heading 3305.10. As it was a concentrate to be mixed with oil and did not fit the specific description, the residuary sub-heading 3305.90 was held to be appropriate.

Issues: (i) Whether an approved excise classification list could be reopened and modified prospectively after issuance of a show cause notice. (ii) Whether the product M-37 was classifiable under Heading 3305.10 or under the residuary Heading 3305.90 of Chapter 33.

Issue (i): Whether an approved excise classification list could be reopened and modified prospectively after issuance of a show cause notice.

Analysis: An assessee cannot claim estoppel against the correct application of law. A different view from an approved classification list may be taken, provided the affected party is put on notice and given an opportunity to respond. A prospective modification of classification, after notice and hearing, does not offend natural justice.

Conclusion: The approved classification list could validly be reopened and modified prospectively; this contention was rejected.

Issue (ii): Whether the product M-37 was classifiable under Heading 3305.10 or under the residuary Heading 3305.90 of Chapter 33.

Analysis: Heading 3302.90 applies only to mixtures of odoriferous substances used as raw materials in industry, which was not established on the facts. The product was not a perfumed hair oil ready for use, because it was only a concentrate to be mixed with oil. At the same time, it remained a preparation for use on hair under Heading 33.05. Since it did not fit the specific description in Heading 3305.10, the residuary sub-heading 3305.90 was more appropriate.

Conclusion: M-37 was not classifiable under Heading 3305.10 and was correctly classifiable under Heading 3305.90.

Final Conclusion: The classification was modified in favour of the assessee to the extent that the product could not be assessed under the specific perfumed hair oil entry, while the challenge to the prospective reopening of the approved classification failed.

Ratio Decidendi: An approved classification may be revised prospectively after notice and hearing, and where a product falls within a broader tariff heading but not the specific entry, classification must be made under the appropriate residuary sub-heading.
