Commissioner of Customs v. Welkin Foods: aluminium mushroom shelving is a structure, not agricultural machinery

The facts in brief

M/s Welkin Foods runs a commercial mushroom-cultivation operation. To equip its climate-controlled growing chambers, it imported flat aluminium shelving from a foreign supplier. The shelves were designed to hold substrate bags and trays in vertical racks inside the growing rooms — the bags would generate the mushrooms; the shelving simply held them at the appropriate height.

At the point of import, Welkin Foods self-classified the consignment under Customs Tariff Item 84369900 — "parts of agricultural machinery" — which attracted Nil basic customs duty under the relevant schedule. The Customs Department disagreed. The assessing officer re-classified the goods under CTI 76109010 — "aluminium structures" — attracting 10% basic customs duty, and raised a demand.

The dispute travelled through the standard appellate chain. The Commissioner (Appeals) upheld the Revenue's re-classification; the Customs, Excise and Service Tax Appellate Tribunal reversed in favour of the importer, accepting the argument that the shelves were exclusively intended for mushroom cultivation and therefore qualified as parts of "agricultural machinery". The Revenue filed Civil Appeal No. 5531 of 2025 before the Supreme Court under Section 130E of the Customs Act 1962, which permits a direct appeal on questions of classification.

A two-judge bench of Justices J.B. Pardiwala and R. Mahadevan heard the appeal and, on 6 January 2026, allowed it. The CESTAT order was set aside; the departmental re-classification under CTI 76109010 was restored. The judgment is the first major customs ruling of 2026 and the first 2026 INSC decision in the tax-and-customs space.

What the tariff actually asks

Chapter 76 of the Customs Tariff Act 1975 covers aluminium and articles thereof. Heading 7610 reads "aluminium structures (excluding prefabricated buildings of heading 9406) and parts of structures …; aluminium plates, rods, profiles, tubes and the like, prepared for use in structures." CTI 76109010 is the residual classification within that group for aluminium structures not falling under more specific sub-entries.

Chapter 84 covers machinery and mechanical appliances. Heading 8436 covers "other agricultural, horticultural, forestry, poultry-keeping or bee-keeping machinery." CTI 84369900 is the residual sub-entry for "other parts" of such machinery.

The General Rules for the Interpretation of the Import Tariff (GIR) supply the analytical sequence. Rule 1 directs that classification is determined according to the terms of the headings and any relative Section or Chapter Notes. Rule 2(a) extends a heading to incomplete or unfinished articles where they have the essential character of the finished good. Rule 3(a) prefers the more specific description over the more general; Rule 3(b) deals with composite goods by reference to the component that gives them their essential character.

The contested question was whether the aluminium shelves — which performed no mechanical function and contained no moving parts — could be characterised as "parts of agricultural machinery" merely because they were intended for installation in a mushroom-growing facility.

What the Court held

The shelves are not "parts" of any machine

The bench rejected the importer's classification at the threshold. A "part" of a machine, in any tariff sense, is a component that contributes to the mechanical function of the machine. The aluminium shelving had no such role. It held substrate bags at a height; the mushrooms grew because of the contents of the bags and the conditions in the chamber, not because of the shelf. The shelf provided a surface; it did not transform, transmit, regulate, or otherwise act upon anything.

The reasoning is structural. To fit CTI 84369900 the goods must qualify either as a machine or as parts of one. The shelving qualified as neither. The CESTAT had elided the distinction by treating exclusive end-use in a mushroom-cultivation facility as a sufficient marker of "agricultural-machinery part" status — a step the apex Court refused to take.

Six principles of the common-or-trade-parlance test

The bench then took the occasion to consolidate the law on the common-or-trade-parlance test, which CESTAT and the High Court tax benches had applied unevenly over decades of customs jurisprudence. The judgment summarises the test in six canonical propositions:

(i) the test is to be applied restrictively, not as a general escape from the tariff text; (ii) its function is limited to ascertaining the common or commercial meaning of a term that already appears within a tariff heading or its defining criterion; (iii) it cannot displace the express text of a tariff entry; (iv) intended end-use does not, by itself, alter classification where the tariff heading rests on the objective characteristics of the goods; (v) where the tariff text is technical, the technical meaning prevails over the common meaning; and (vi) the burden lies on the party seeking to displace the natural reading of a tariff entry.

The six-point distillation is the judgment's most reusable contribution. CESTAT benches now have a checklist; assessing officers have a framework; importers have a clear allocation of evidentiary burden.

Objective characteristics over intended end-use

The bench reaffirmed the broader doctrinal preference for characteristic-led classification. The Customs Tariff describes goods as they are imported — by their constituent material, their structural form, their objective use-capacity. End-use rhetoric is admissible only where the tariff entry itself opens that door (for example, headings that turn explicitly on "use" or "specially designed for"). For headings that classify by objective form — like Heading 7610 — the importer's plans for the goods after clearance are doctrinally irrelevant.

This resolves a long-running CESTAT tension between the use-test line (drawn from decisions such as L.M.L. Ltd. v. Commissioner of Customs) and the characteristic-test line (HPL Chemicals v. Commissioner of Central Excise). The Welkin bench plants the flag firmly on the characteristic side for entries that do not invite end-use enquiry.

The doctrinal architecture

Three moves stand out.

First, the six-principle distillation of the common-or-trade-parlance test gives the doctrine a structure it had lacked. The test had been recited in dozens of CESTAT orders without a settled internal grammar; the bench's articulation now supplies one. The principles will travel — they are general enough to apply to any classification dispute, and they re-allocate the burden of displacement onto the party seeking to read the tariff against its natural grain.

Second, the end-use-vs-characteristics rebalancing has implications well beyond aluminium shelving. The GST Schedule is closely aligned with the Customs Tariff for HSN classification purposes; the Welkin bench's preference for objective characteristics will be cited in GST classification disputes — particularly for goods imported or supplied under end-use-tagged entries (hydroponics infrastructure, climate-controlled storage, dairy and poultry equipment, agricultural processing kit).

Third, the burden-of-displacement rule materially affects litigation strategy. Where the natural reading of the tariff supports the Revenue's classification, the importer must come forward with the evidence that justifies a departure — technical, commercial, or structural. The default is the tariff; the exception requires proof.

What the judgment did not decide

The judgment did not address whether aluminium shelving designed and supplied as part of a fully integrated mushroom-cultivation system — with sensors, irrigation lines, climate controls, and the shelving as one component of a composite, pre-fabricated functional unit — would fall under Chapter 84 as part of a composite machine. That question turns on whether the imported consignment can satisfy the GIR Rule 2(a) "essential character" test for unfinished or incomplete goods, and would have to be litigated on its own facts.

It did not address concessional-duty entitlement under Notification No. 50/2017-Customs (Welkin Foods had argued for Nil duty under the agricultural-machinery exemption — that argument fell with the classification reasoning).

And it did not address the parallel GST classification question for similar shelving supplied domestically; the implications for GST HSN coding will have to be worked out in pending matters.

After the judgment

The Central Board of Indirect Taxes and Customs is likely to circulate the six-principle framework to all field formations, framing the Welkin checklist as standard departmental doctrine for end-use-driven classification disputes. Expect a wave of departmental re-assessments where importers have invoked "parts of machinery" entries on the basis of intended end-use alone — particularly in the agricultural-equipment, climate-controlled storage, hydroponics, and food-processing infrastructure sectors.

CESTAT benches will need to recalibrate. The use-test reasoning that had crept into a number of decisions over the last decade will have to be revisited against the Welkin framework. Expect a tightening of CESTAT orders to anchor classification more firmly in objective characteristics.

The judgment also has spillover into GST classification disputes. Because the GST Schedule mirrors the Customs Tariff for HSN purposes, the Welkin principles will be cited in pending GST matters involving end-use-tagged classifications — particularly disputes over rates for solar-power components, agricultural inputs, and prefabricated structures. International trade practitioners should audit their HSN classifications for end-use-tagged consignments and assess whether the natural reading of the tariff entry supports the chosen sub-heading.
