....objectively, it is specifically designed for and functionally integrated with the analytical instrument. • Chapter 90 Note 2(b) directs that parts and accessories suitable for use solely or principally with a particular instrument are to be classified with that instrument, subject to the prior operation of Note 2(a) where the article is itself covered by a separate heading. • Heading 3926, as a residual heading for other articles of plastics, cannot displace a specific Chapter 90 classification that follows from the relevant Chapter Note. Background & Context The classification dispute concerned STA micro-cuvettes used in a blood coagulation analyser. The goods were sealed cartridge assemblies with a plastic ....

.... requires that "the heading which provides the most specific description shall be preferred to headings providing a more general description". Rule 3(b), applicable only where Rule 3(a) does not resolve the issue, classifies composite goods according to the material or component that gives them their essential character. Chapter 90 Note 2 Chapter 90 Note 2 establishes a sequence for parts and accessories. Note 2(a) requires parts and accessories which are themselves goods included in a heading of Chapter 90 or of Chapters 84, 85 or 91, subject to specified exclusions, to be classified in their respective headings. Note 2(b) then applies to "other parts and accessories" which are suitable for use solely or principally with a particular....

....vidence recorded, the micro-cuvettes had no established practical use with other instruments. They were essential to conducting the intended test, even though the analyser remained physically intact when a cuvette was not inserted. The relevant question was therefore whether the article was essential to the intended analytical operation, rather than whether it was permanently installed in the instrument or whether the instrument could be switched on without it. This approach accords with 2010 (7) TMI 20 - Supreme Court. That decision treated controllers, input-output modules and chassis as Chapter 90 parts or accessories because their technical characteristics showed that they contributed to a defined measuring or controlling function.

....ly used up in a process without operating as a functional component may remain a consumable supply. Circular No. 19/2013-Customs illustrates the importance of following the Note 2 sequence. It addressed disposable filters used in blood purification and clarified that they were classifiable under tariff item 84212900 because they were themselves covered by Heading 8421. The circular specifically applies Rule 1 and Chapter 90 Note 2(a), under which an article with its own applicable heading is classified there rather than with the larger medical system. The circular does not create a rule that all disposable medical or analytical components must be treated as consumables or as plastic articles. The limits of sole-use and material-based ....

....uishable because the goods were not found to be general-use plastic articles; their specific design and analytical role attracted Chapter 90 Note 2(b). 2007 (4) TMI 263 - Supreme Court further establishes that plastic composition does not preclude classification as a part or accessory. Plastic name plates were held to be vehicle accessories because they added identity, effectiveness and market value, and no applicable exclusion required their relegation to Chapter 39. The principle supports the proposition that the material of construction is relevant only when it is made relevant by the tariff terms and notes; it is not a substitute for examining the article's actual tariff identity. Specific Chapter 90 treatment over the residua....

....eme and the product's objective characteristics. • A Chapter 90 Note 2 analysis should be sequenced correctly: first determine whether Note 2(a) assigns the article to its own heading; only thereafter consider Note 2(b) for other dedicated parts or accessories. • Arguments based only on plastic content are vulnerable where the article has acquired a distinct identity as a specially designed functional component. Equally, a claim based solely on machine-specific use will fail where a specific plastic heading, an exclusionary note, or general-use character governs the article. • Foreign or private rulings require caution. Their relevance depends on a demonstrated parity between the governing tariff p....
