Imported aluminium shelves' tariff classification-CTI 76109010 aluminium structures vs CTI 84369900 machinery parts; appeal allowed.

The dominant issue was tariff classification of imported aluminium shelves as "parts" of agricultural machinery under CTI 84369900 or as aluminium structures under CTI 76109010. Applying GRIs sequentially and the "as imported" principle, the SC held that common/trade parlance and "use" are relevant only where the heading so indicates and must be inferred from objective characteristics, not actual post-import use. The shelves satisfied the two-part test for CTI 76109010 (aluminium; structure/part of structure). They were not classifiable under Heading 8436 because the mushroom-growing apparatus was neither a composite machine nor a functional unit, and the shelves did not qualify as "parts" since the machines were complete and operational without them. The impugned judgment was set aside and the appeal allowed.

1. ISSUES PRESENTED AND CONSIDERED

(i) Whether the imported aluminium shelving is classifiable as "structures" under CTI 76109010 or as "parts" of agricultural machinery under CTI 84369900.

(ii) Whether Chapter Heading 8436 can apply when the subject goods are neither "machinery" nor "parts" of machinery, and the asserted mushroom-growing "apparatus" does not qualify as machinery, a composite machine, or a functional unit.

(iii) Whether the Tribunal erred by invoking GRI 3 (specific-vs-general) without first establishing, under GRI 1, that the goods are prima facie classifiable under both competing headings, and by relying on unproven assertions of "no other purpose" and "trade parlance."

2. ISSUE-WISE DETAILED ANALYSIS

A. Classification of the subject goods: "aluminium structures" (CTI 76109010) vs "parts of agricultural machinery" (CTI 84369900)

Legal framework (as discussed by the Court): The Court applied the First Schedule classification methodology, emphasising that GRIs must be applied sequentially, beginning with GRI 1 (terms of headings plus relevant Section/Chapter Notes). The Court treated aligned HSN Explanatory Notes as binding guidance. It also relied on Section Note 1(f) of Section XV (excluding "articles of Section XVI" from Section XV) and the Explanatory Notes' exclusion of "assemblies identifiable as parts of articles of Chapters 84 to 88" from heading 7610.

Interpretation and reasoning: For heading 7610, the Court held the criterion is twofold: the goods must be made of aluminium and must be "structures" (or parts of structures). Using the Explanatory Notes' characteristics of structures (once installed they generally remain in position; assembled from prepared components joined by bolting/riveting/welding, etc.), the Court found the aluminium shelving satisfies these objective characteristics and properties. The Court additionally stated that even in common parlance the subject goods would be referred to as structures.

For heading 8436/parts under 84369900, the Court held that 8436, though eo nomine ("agricultural machinery"), inherently involves a use aspect, but the threshold inquiry remains whether the goods (or the relevant "apparatus" to which they allegedly belong) are "machinery" within the heading. The Court found the shelving is static and non-moving, is not understood as "machinery" in common parlance, and its classification as machinery would be "patently absurd." The Court further held that Section Note 5 of Section XVI (defining "machine" for the purposes of Section Notes) does not expand the scope of a specific tariff heading that uses only the term "machinery."

Conclusions: The subject goods are classifiable as "structures" under CTI 76109010. They cannot be classified under Chapter Heading 8436/CTI 84369900 because neither the subject goods nor the alleged mushroom-growing "apparatus" qualifies as "machinery" for that heading, and the subject goods are not "parts" of any such machinery.

B. Whether the asserted mushroom-growing "apparatus" qualifies as machinery, composite machine, or functional unit under Section XVI notes

Legal framework (as discussed by the Court): The Court examined the relevant Section XVI Notes and Explanatory Notes on composite machines (Note 3) and functional units (Note 4), and the meaning and operation of those concepts.

Interpretation and reasoning: The Court found the mushroom-growing arrangement described on record to be a combination of separate machines performing independent tasks (e.g., watering, compost-related functions), united only by their participation in the broader cultivation process. On that basis, it held the arrangement is not a composite machine (not designed to be fitted together permanently) and not a functional unit (the components do not contribute together to a single clearly defined function covered by a heading; rather they perform separate functions).

Conclusions: The mushroom-growing "apparatus" does not qualify as "machinery" under Chapter Heading 8436 via composite-machine or functional-unit concepts; therefore, classification of the shelving as parts of such "machinery" necessarily fails.

C. Whether the shelving is a "part" of agricultural machinery

Legal framework (as applied by the Court): The Court applied its settled understanding that a "part" is an integral/constituent component essential for the article to be complete and functional.

Interpretation and reasoning: The Court held that the machines said to be mounted or integrated post-import are self-contained and operational; their mechanical/electrical functions do not rely on the shelving. The shelves merely provide a surface or platform. The Court reasoned that providing a surface that supports an object does not make the surface a "part" of that object, and rejected the proposition that being custom-made to allow integration automatically makes an item a "part."

Conclusions: The subject goods are not "parts" of agricultural machinery for CTI 84369900.

D. Errors in the Tribunal's approach: sequential application of GRIs and reliance on unproven "trade parlance/no other purpose" findings

Legal framework (as discussed by the Court): GRIs must be applied sequentially; GRI 3 is only reached after GRI 1 (and where relevant GRI 2) yields prima facie classification under two or more headings.

Interpretation and reasoning: The Court held the Tribunal erred in applying the "more specific heading" approach (GRI 3(a)) without first establishing that, under GRI 1, the goods are prima facie classifiable under both headings. Separately, the Court found the Tribunal's conclusions that the shelves had "no other purpose" and that they were known in "trade parlance" as mushroom racks were unsupported by reasoning or evidence; marketing materials and the seller's line of business were insufficient to establish such specialised trade meaning or exclusive-purpose limitation.

Conclusions: The Tribunal's classification reasoning was flawed; the correct classification remains CTI 76109010 as aluminium structures.
