2026 (1) TMI 348 - Supreme Court

At a Glance

A customs classification dispute arose concerning imported aluminium shelving designed for a specialised agricultural activity. The importer classified the shelving as parts of agricultural machinery under Customs Tariff Item (CTI) 84369900, while the revenue authority treated it as aluminium structures under CTI 76109010, with materially different duty consequences.

The Court resolved the dispute by applying the Harmonised Systembased framework under the Customs Tariff Act, 1975, emphasising (i) the sequential application of the General Rules for Interpretation (GRI), (ii) the limited role of the common/trade parlance test, (iii) the restricted and objective use-based inquiry (the as imported principle), and (iv) a strict concept of parts that excludes mere supporting platforms or structures.

In principle, the Court held that the shelving was classifiable as an aluminium structure under CTI 76109010 and not as parts of agricultural machinery under CTI 84369900.

Factual Background

The assessee imported aluminium shelving, along with other items (including a floor drain and an automatic watering system), and filed a bill of entry under Section 46 of the Customs Act, 1962. The aluminium shelving was described as shelving for use in the relevant agricultural activity and was declared under CTI 84369900 (parts of agricultural machinery).

While the other imported items were accepted as classifiable under CTI 84369900, audit scrutiny led the department to dispute the classification of the aluminium shelving. The departments position was that the shelving was not a part of agricultural machinery but an aluminium structure classifiable under CTI 76109010, attracting a higher duty incidence (including basic customs duty stated at 10% under that tariff item).

A show cause notice was issued under Section 28(1) of the Customs Act, 1962 seeking reclassification and recovery of the alleged short levy, along with interest under Section 28AA. The adjudicating authority and the first appellate authority upheld classification under CTI 76109010, primarily by applying GRI 1. The tribunal, however, allowed the assessees appeal and classified the shelving under CTI 84369900, invoking considerations such as the specialised design and trade parlance.

The department challenged the tribunals approach before the Court.

Issues Before the Court

• Whether the subject aluminium shelving was classifiable as parts of machines or mechanical appliances of Chapter 84 under CTI 84369900, or as aluminium structures of Chapter 76 under CTI 76109010.
• Whether, and to what extent, common/trade parlance and use can be relied upon in classification disputes under the First Schedule to the Customs Tariff Act, 1975.
• How the General Rules for Interpretation (GRI 1 to GRI 6) and the relevant Section Notes, Chapter Notes, and HSN Explanatory Notes govern the classification analysis.

Courts Reasoning

1) Statutory architecture: Customs levy and tariff classification

The Court rooted the classification inquiry in Section 12(1) of the Customs Act, 1962 (charging provision for customs duties) read with Section 2 of the Customs Tariff Act, 1975 (rates specified in the Schedules). Classification under the First Schedule to the Customs Tariff Act, 1975 determines duty incidence and cannot be treated as a merely administrative exercise.

2) Sequential application of the General Rules for Interpretation

The Court emphasised that GRIs in the First Schedule to the Customs Tariff Act, 1975 must be applied sequentially. GRI 1 is the non-negotiable starting point: classification is determined according to the terms of headings and any relevant Section Notes and Chapter Notes. GRI 2 expands headings for incomplete/unassembled goods and for mixtures/composite goods, while GRI 3 operates only as a tie-breaker when goods are prima facie classifiable under multiple headings. GRI 4 is a last resort and is mutually exclusive with an analysis under GRI 3.

On this basis, the Court found fault with an approach that jumps to specific over general reasoning (GRI 3(a)) without first establishing, under GRI 1 (and where relevant GRI 2), that the goods are prima facie classifiable under both competing headings.

3) Role of HSN Explanatory Notes and the alignment condition

The Court held that HSN Explanatory Notes are authoritative guidance for interpreting tariff headings under the HSN-based regime, where the domestic headings are aligned with the corresponding HSN headings and no explicit deviation is shown in the domestic statute. On the facts, the Court proceeded on the footing that the relevant competing headings (Chapter Heading 7610 and Chapter Heading 8436) were aligned with HSN counterparts, permitting reliance on the Explanatory Notes as binding guidance.

4) Common/trade parlance: a restricted tool, not a first resort

The Court reaffirmed that the common parlance (including trade/commercial/popular parlance) test is applicable primarily where the statute does not define a term and provides no clear interpretative criteria through headings, Section Notes, Chapter Notes, or aligned Explanatory Notes. It must not be used where statutory context provides definitive guidance, where terms are used in a technical/scientific sense, or where applying parlance would undermine the tariff scheme.

Further, where a party asserts a specialised trade meaning or a no other purpose claim, the Court indicated that the evidentiary standard is stringent and cannot be satisfied by marketing materials or general assertions alone.

5) Use in classification: intended use must be statutorily permitted and objectively ascertainable

The Court addressed the recurring controversy over end-use in classification disputes. It reiterated the as imported principle: the taxable event occurs at importation under Section 12 of the Customs Act, 1962; therefore, classification must be anchored in the condition of the goods at the time of import.

Use can be relevant only when the tariff heading (or the relevant Notes) explicitly or inherently permits a use/adaptation inquiry. Even then, the relevant inquiry is intended use, discernible from objective characteristics and properties (including function, design, and composition), and not the actual post-import use.

6) Competing headings: CTI 76109010 versus CTI 84369900

(a) CTI 76109010 (Chapter Heading 7610): aluminium structures

Under Chapter Heading 7610, the Court identified a two-part requirement: (i) the goods must be of aluminium; and (ii) they must be structures or parts of structures. Since the tariff does not define structure, the Court relied on the aligned Explanatory Notes (via the Explanatory Note to Heading 73.08 applied mutatis mutandis), which describe structures as characteristically remaining in position once installed and being made up of prepared components joined by bolting, welding, riveting, etc.

On objective characteristics, the Court held the subject shelving met the characteristics of structures and therefore fell within CTI 76109010.

(b) CTI 84369900 (Chapter Heading 8436): parts of agricultural machinery

Chapter Heading 8436 covers specified categories of agricultural/horticultural machinery and parts. The Court accepted that the expression agricultural machinery inherently carries a use element (field-of-industry grouping), and it treated the appropriate use standard as principal use, not any incidental use.

However, the Court insisted on the eo nomine threshold first: the heading is for machinery; therefore, the goods (or the relevant apparatus to which they are claimed to belong) must meet the identity of machinery under that heading before parts classification can be considered.

The assessee relied on Section Note 5 of Section XVI (defining machine for the purposes of the Section Notes as including machinery, plant, equipment, apparatus or appliance cited in headings of Chapter 84 or 85). The Court rejected the contention that this expanded the scope of the tariff heading itself; it treated Section Note 5 as an interpretative convenience for the purposes of these Notes, not as a device to rewrite a heading that uses the term machinery. It also read the specific inclusion of germination plant within Chapter Heading 8436 as reinforcing that other plant concepts are not automatically absorbed into machinery under that heading.

7) Meaning of parts: essential functional component, not a mere platform

The Court treated parts as integral or constituent components essential to completeness and functional operation. It held that a supporting structure on which machines are mounted does not become a part merely because it facilitates use or integration. The Court analogised that a surface may support an object without being part of the objects mechanism.

Applying this, the Court held that the machines integrated post-import were self-contained and did not mechanically or operationally depend on the aluminium shelving. The shelving did not contribute to their operation; it served as a platform. Accordingly, the shelving failed the parts test for CTI 84369900.

8) Section and Explanatory Note exclusions: Section XV versus Section XVI

The Court highlighted that Section Note 1(f) of Section XV excludes articles of Section XVI from Section XV, and the Explanatory Notes to Heading 7610 exclude assemblies identifiable as parts of articles of Chapters 84 to 88. This structural logic avoids the absurdity of classifying most machinery as mere articles of base metal because machinery is commonly made of base metals.

However, because the subject goods were held not to be classifiable under Chapter Heading 8436 as machinery/parts, the exclusions did not displace classification under Chapter Heading 7610.

9) Critique of the tribunals approach

The Court found the tribunals reliance on trade parlance and no other purpose reasoning insufficiently grounded in objective findings and evidence. It also found the tribunals invocation of more specific heading logic under GRI 3(a) to be non-sequential and legally erroneous in the given setting.

Decision & Ratio

The Court allowed the departments appeal and set aside the tribunals classification. It held that the aluminium shelving was classifiable as aluminium structures under CTI 76109010 (Chapter Heading 7610), and not as parts of agricultural machinery under CTI 84369900 (Chapter Heading 8436).

Ratio (in principle): In classification disputes under the Customs Tariff Act, 1975, (i) GRIs must be applied sequentially with primacy to GRI 1; (ii) HSN Explanatory Notes operate as binding guidance where aligned; (iii) common/trade parlance is a restricted interpretative tool usable only in statutory silence; (iv) use-based classification depends on statutory permission and must be determined from intended use inherent in objective characteristics, consistent with the as imported principle; and (v) parts require an essential functional nexusmere platforms/supporting structures are not parts of machinery.

Practical Implications

1) Stronger discipline in classification methodology

The decision reinforces that practitioners must structure classification opinions and litigation strategy around GRI 1 and the relevant Section Notes/Chapter Notes before resorting to GRI 3. Arguments based on specific over general must be positioned only after establishing a prima facie overlap under the earlier GRIs.

2) Evidence burden for trade parlance and sole/unique use claims

Where assessees rely on trade parlance or no other purpose assertions to exit an eo nomine heading, they must be prepared with cogent evidence demonstrating substantial transformation in identity and objective design constraints, not merely brochures, vendor specialization, or end-use narratives.

3) Constrained scope of end-use arguments

The decision limits reliance on end-use to cases where the heading/notes make use/adaptation relevant, and even then focuses on intended use objectively manifest at importation. Practically, this reduces the persuasive value of post-import integration narratives unless supported by objective characteristics intrinsic to the imported goods.

4) Parts litigation: functional necessity is the core test

The reasoning provides a clear litigation filter: components that merely support or house machinery, without contributing to its mechanical/electrical operation, face significant risk of being excluded from parts headings, especially when they resemble structures under material-based headings (such as Chapter Heading 7610).

5) Interaction between Section XV and Section XVI

The decision highlights how exclusionary notes (Section Note 1(f) of Section XV; Explanatory Note exclusions under Heading 7610) should be deployed in pleadings. However, these exclusions will operate only if the competing Section XVI classification is first established on its own terms.

Key Takeaways

• Classification under the First Schedule to the Customs Tariff Act, 1975 must begin with GRI 1, reading headings with relevant Section Notes and Chapter Notes; GRI 3 is not a starting point.
• HSN Explanatory Notes are decisive guidance where domestic headings are aligned and no statutory deviation is shown.
• The common/trade parlance test is a restricted tool, applicable primarily where statutory text and aligned notes provide no clear guidance; it cannot override the tariff scheme.
• Use is relevant only where the tariff heading/notes permit it; the operative inquiry is intended use inherent in objective characteristics, consistent with the as imported principle.
• A part must be an essential constituent for functional operation; a supporting shelf/platform, even if custom-designed for integration, does not become a part merely by facilitating installation or use.
• Aluminium assemblies that meet the objective characteristics of structures (remaining in position post-installation; assembled from prepared components) can fall under Chapter Heading 7610 and CTI 76109010 unless displaced by a valid Section XVI classification.

2026 (1) TMI 348 - Supreme Court

Aluminium shelving classed by import condition: use allowed only if statutorily permitted; supports aren't parts at import. Classification requires sequentially applying GRI 1 with relevant Section and Chapter Notes; aligned HSN Explanatory Notes guide interpretation. Use is relevant only where permitted and must reflect intended use objectively evident at importation per the as imported principle. A 'part' must have an essential functional nexus to machine operation; mere supporting platforms or shelves that do not contribute mechanically to operation are not parts and may instead fall under material-based structure headings.
