Carestream Health: Cross-heading compatibility sends medical laser imagers to CTH 9033

Case in Brief

M/s Carestream Health India Pvt. Ltd. challenged the classification of its imported Dryview 6850 Laser Imagers W/3D under CTH 9018 90 19, which covers other diagnostic instruments and apparatus. The Customs authorities classified them under residuary CTH 9033 00 00 as parts and accessories for Chapter 90 equipment, a view affirmed by the CESTAT.

The Supreme Court dismissed the appeal under Section 130E(b) of the Customs Act, 1962, holding that the imager had no diagnostic capability of its own and was an accessory usable with machines falling under both CTH 9018 and CTH 9022. That cross-heading compatibility attracted Rule 2(c) of Chapter 90 Note 2 and required classification under CTH 9033 00 00.

Key Takeaways

• An imported device that merely receives diagnostic data and prints it on film is an accessory to diagnostic equipment, not a diagnostic apparatus in its own right.

• Chapter 90 Note 2(b) applies where an accessory is suitable solely or principally with a particular kind of machine, or with machines under the same tariff heading; it does not govern an accessory usable with machines under different tariff headings.

• An accessory compatible with machines under both CTH 9018 and CTH 9022 falls under the residuary CTH 9033 00 00 when no specific heading otherwise covers it.

• A notification prescribing concessional duty for goods under specified tariff headings cannot be invoked without establishing compliance with its conditions, particularly where the benefit is raised for the first time before the Supreme Court.

Facts

Carestream imported the Dryview 6850 Laser Imagers W/3D from China under a Bill of Entry dated 2 April 2013. The equipment uses photo-thermographic dry-laser technology to develop images on film and interfaces with MRI, CT, full-field digital mammography, digital radiology, computed radiography, PACS and other systems. It can also be used for other grayscale film applications.

The importer classified the goods under CTH 9018 90 19 as other diagnostic instruments and apparatus. The Assistant Commissioner rejected that classification on 24 June 2013 and ordered classification under CTH 9033 00 00. The Commissioner (Appeals) affirmed the decision on 10 March 2014, and the CESTAT dismissed the importer’s appeal on 21 August 2024.

The differential duty involved was ₹5,21,616, reflecting a 2.5% difference in the applicable duty at the relevant time. The importer maintained that the laser imager was an apparatus used for diagnostic purposes; the Revenue characterised it as an accessory usable with equipment across different tariff headings.

Issues

1. Whether the imported laser imager was itself a diagnostic instrument or apparatus classifiable under CTH 9018 90 19, or an accessory falling under CTH 9033 00 00.

2. If treated as an accessory, whether Chapter 90 Note 2(b) permitted classification with diagnostic machines under CTH 9018 because the imager was compatible with several such machines.

3. Whether compatibility with machines under separate headings—CTH 9018 and CTH 9022—necessarily brought the goods within Rule 2(c) and CTH 9033 00 00.

4. Whether Notification No. 12/2012 dated 17 March 2012 could secure a 5% concessional rate for the importer despite the notification being relied upon for the first time before the Supreme Court.

Court's Reasoning

The Court first rejected the attempt to characterise the imager by reference to the medical context in which it was used. Its decisive functional finding was that the device had no independent diagnostic skill or capability. It had to receive inputs from diagnostic equipment and then print those inputs on film. CTH 9018 90 19 was confined to other diagnostic instruments and apparatus; the imager could not enter that heading merely because the data it printed originated in medical diagnosis.

The Court distinguished the function of the imager from the function of the diagnostic machine. The MRI, CT or other medical equipment completed the diagnostic exercise independently. The imager did not aid or augment that performance; it performed the ancillary task of transferring transmitted diagnostic data onto film for preservation or subsequent use. It was therefore an accessory, although not a physical part of the diagnostic machine. The Court used the distinction between a part and an accessory in that sense: the imager was independent of the principal machine but supplied a supplementary service to it.

The Court considered the importer’s reliance on Commissioner of Customs, New Delhi v. C-Net Communication (India) (Pvt.) Ltd. The decision did not assist because the present inquiry was not whether the imager was indispensable to the operation of the medical equipment. C-Net’s functional approach, properly applied, supported the Revenue: the imager did not contribute to the diagnostic function and only printed the output. The Court also referred to Annapurna Carbon Industries Company v. State of Andhra Pradesh for the proposition that an accessory may be manufactured as an aid or addition without being confined to one particular machine; the same item may be an accessory to more than one kind of instrument.

The classification then turned on Note 2 to Chapter 90. Rule 2(a) was excluded because the imager was not itself a good included in a heading of Chapter 90, Chapter 84, Chapter 85 or Chapter 91 of the kind specified there. Rule 2(b) directs that other parts and accessories suitable for use solely or principally with a particular kind of machine, or with a number of machines or apparatus of the same heading, are to be classified with those machines. Rule 2(c) sends all other parts and accessories to CTH 9033.

The importer argued that compatibility with several machines under CTH 9018 satisfied Rule 2(b). The Court disagreed because the catalogue also showed compatibility with CT apparatus, X-ray generators, portable X-ray machines and other radiation-based apparatus under CTH 9022. The language of Rule 2(b) was treated as deliberately distinguishing accessories suitable for machines under the same heading from those suitable for machines under different headings. The Court regarded the tariff consequences as reinforcing that reading: MRI and linear ultrasound equipment under CTH 9018 attracted 7.5% at the relevant time, while CT apparatus under CTH 9022 attracted 10% per unit and non-portable X-ray generators and apparatus attracted 15% per unit. It found little rationale in assigning one cross-heading accessory to a principal-machine heading where the potential principal machines attracted materially different rates.

The resulting rule is categorical on the facts presented: an accessory suitable for several machines under the same tariff heading may be classified with those machines; an accessory suitable not only for machines under one heading but also for machines under another heading is to be brought under the residuary CTH 9033 00 00. The Court accepted the CESTAT’s interpretation and dismissed the appeal.

The notification argument failed independently. Sl. No. 473 of Notification No. 12/2012 covered specified goods required for medical, surgical, dental or veterinary use falling under CTH 9018, 9019, 9020, 9021 or 9022, at 5%. CTH 9033 was not mentioned. More fundamentally, the importer had not relied on the notification before the lower authorities and had not established compliance with the annexure’s conditions. The Court held that foundational compliance could not be assumed or supplied for the first time at the Supreme Court stage.

Important Observations

The judgment places the device’s independent functional capability above its commercial setting. A product does not become medical diagnostic apparatus because it is marketed for use in a diagnostic workflow or because its output is used by medical professionals. The relevant inquiry is what the imported article itself does.

The decision also gives operative content to the same-heading limitation in Rule 2(b). Multiple compatible machines within one heading do not defeat that rule; compatibility extending across separate tariff headings does. The Court’s reasoning makes the tariff heading, rather than the broad industrial sector or end-use label, the controlling classification boundary for accessories.

The discussion of Notification No. 12/2012 reiterates a procedural discipline with substantive consequences: exemption or concessional-rate notifications are conditional instruments. A claimant must identify the precise entry and prove the prescribed conditions; the Court will not treat a late invocation as self-executing.

Why This Judgment Matters

For customs classification disputes, Carestream supplies a practical two-stage inquiry. Counsel should first establish whether the imported article independently performs the function described in the claimed heading. If it does not, the case moves to the parts-and-accessories note. Product catalogues, interface specifications and compatibility matrices then become central evidence, because they may show use with machines outside the importer’s preferred heading.

The ruling is particularly important for peripheral equipment in medical imaging, laboratory and technical systems: printers, output devices and other ancillary modules may be used in a specialised clinical environment without being classifiable as medical instruments. Importers seeking classification with a particular heading will need to demonstrate not merely substantial use with machines under that heading, but the absence of qualifying use with machines under another tariff heading where Rule 2(c) is invoked.

The judgment does not elaborate a quantitative test for solely or principally—such as market share, sales data, technical design or actual import-use patterns. Nor does it resolve how the analysis would operate where cross-heading compatibility is technically possible but commercially marginal, or where a device performs a more active role in diagnosis. Those questions remain open for fact-specific adjudication. The treatment of C-Net is also confined to the functional distinction identified here, rather than a broad rejection of functional classification reasoning. Finally, the notification discussion warns litigants against attempting to cure an evidentiary and pleading omission at the final appellate stage.
