Plastic tanks and vats classified as builders' ware of plastics; limitation issue remitted for fresh decision.

Plastic tanks and vats were treated as goods specifically covered by Chapter Note 11(a) of Chapter 39 and, on their description, purpose and use, were classifiable under Heading 39.25 as builders' ware of plastics rather than under the residuary sub-heading 3926.90. The classification analysis applied the tariff scheme and, where the interpretative rules did not resolve the issue, the goods were classified by their closest answer under Rule 4. The limitation issue under the proviso to Section 11A was not decided by the Tribunal and was remitted for first-instance adjudication.

Issues: (i) Whether the plastic tanks and vats manufactured by the assessee were classifiable under Heading 39.25 as builders' ware of plastics or under sub-heading 3926.90 as other articles of plastics; (ii) whether the question of limitation under the proviso to Section 11A required reconsideration.

Issue (i): Whether the plastic tanks and vats manufactured by the assessee were classifiable under Heading 39.25 as builders' ware of plastics or under sub-heading 3926.90 as other articles of plastics.

Analysis: The correct classification had to be determined by the description, purpose and use of the goods, read with the interpretative scheme of the Tariff. Note 11(a) of Chapter 39 expressly covers reservoirs, tanks, vats and similar containers under Heading 39.25. Where direct application of Rules 1 to 3 of the Interpretative Rules does not resolve the dispute, Rule 4 requires classification under the heading to which the goods are most akin. The tanks and vats manufactured by the assessee answered the description in Heading 39.25 and were capable of use for water storage and similar purposes connected with construction or industrial use.

Conclusion: The goods were classifiable under Heading 39.25 as builders' ware of plastics and not under sub-heading 3926.90.

Issue (ii): Whether the question of limitation under the proviso to Section 11A required reconsideration.

Analysis: Since the Tribunal had allowed the assessee's appeals only on the classification issue, it had not adjudicated the applicability of the extended period of limitation. That question, therefore, remained undecided and had to be examined by the Tribunal in the first instance.

Conclusion: The question of limitation was remitted to the Tribunal for decision.

Final Conclusion: The classification finding in favour of the Revenue was restored, but the matter was sent back for adjudication of the limitation question.

Ratio Decidendi: Where goods fall within a specific tariff description by reason of their nature, purpose and use, and the goods are expressly covered by the relevant chapter note, they cannot be classified under a residuary entry merely because they are also capable of industrial use; unresolved limitation issues may be remitted for fresh decision when not previously decided.
