Activated bentonite classification and limitation: tariff text controlled the heading, and extended demand failed without suppression.

Activated bentonite clay was held classifiable under Heading 3802 before 1-2-2003 and from 1-1-2007 onwards because Chapter Note 1, the HSN Explanatory Notes and the Board circular treated activated clay as outside Chapter 25; however, it fell under specific sub-heading 2508 10 90 from 1-2-2003 to 31-12-2006 when that tariff entry expressly covered activated bentonite. On limitation, the extended period was unavailable absent suppression or misdeclaration, and a mere wrong claim of classification did not by itself justify extended demand; time-barred demands and related confiscation, fine and penalty were set aside, subject to demands within limitation or arising from provisional assessment.

Issues: (i) Whether activated bentonite clay is classifiable under Heading 2508 or Heading 3802 of the Customs Tariff for the different periods involved. (ii) Whether demands raised beyond the normal period of limitation could be sustained and whether penal consequences followed.

Issue (i): Whether activated bentonite clay is classifiable under Heading 2508 or Heading 3802 of the Customs Tariff for the different periods involved.

Analysis: Chapter Note 1 to Chapter 25 excludes products that have undergone processing beyond the processes mentioned in the chapter and, where activation changes the structure of bentonite, the product falls outside Chapter 25. The HSN Explanatory Notes to Heading 25.08 exclude activated clay and the Notes to Heading 38.02 specifically cover activated clays and activated earths. The Board circular also clarified that activated bentonite is classifiable under Heading 3802. However, when the eight-digit tariff specifically included activated bentonite in sub-heading 2508 10 90 from 1-2-2003, that specific tariff description governed until it was amended by Notification No. 137/2006-Cus. (N.T.), which omitted the word "activated" with effect from 1-1-2007.

Conclusion: Activated bentonite was classifiable under Heading 3802 prior to 1-2-2003 and from 1-1-2007 onwards, but was classifiable under sub-heading 2508 10 90 for the period from 1-2-2003 to 31-12-2006 because of its specific tariff entry.

Issue (ii): Whether demands raised beyond the normal period of limitation could be sustained and whether penal consequences followed.

Analysis: For invoking the extended period, the department had to establish suppression or misdeclaration. The order holds that a wrong claim of classification by the importer, by itself, is not suppression, and that the department remained responsible for assessment and verification. In view of the Board circular, departmental awareness of the product and the department's own assessments in similar cases, extended limitation was not available where the demands were raised beyond the normal period. The relevant date for limitation was taken as the date of service of the notice, and not merely the date of issue of the notice, while provisional assessments stood on a different footing.

Conclusion: Demands raised beyond the normal period were not sustainable except where provisional assessments were involved or where the demand was within limitation; confiscation, fine and penalty were not warranted on the classification dispute.

Final Conclusion: The appeals were disposed of by sustaining only those demands that were within limitation or arose from provisional assessments, while setting aside time-barred demands and related penal consequences.

Ratio Decidendi: Classification of activated bentonite turns on the tariff text read with the chapter notes and HSN Explanatory Notes, and the extended period of limitation cannot be invoked merely because the importer claimed an unsustainable classification in the absence of suppression or misdeclaration.
