Tariff classification of laboratory glassware depends on the Customs Tariff Act; foreign explanatory notes cannot override statutory wording.

Imported reaction glass vessels used in a research and development unit were treated as laboratory glassware under Heading 70.17/18 of the Customs Tariff Act, 1975, because the record supported their laboratory use and no contrary material displaced that characterisation. Explanatory notes from the Brussels Tariff Nomenclature could not exclude the goods, as those notes are not part of the Act and cannot override its wording where no corresponding statutory exclusion exists. The classification under Heading 70.17/18 was therefore accepted, and the alternative assessment under Heading 70.21 was not sustained.

Issues: Whether the imported reaction glass vessels were classifiable as laboratory glassware under Heading 70.17/18 of the Customs Tariff Act, 1975, and whether the Brussels Tariff Nomenclature explanatory notes could be applied to exclude such goods from that heading.

Analysis: The goods were found to be used in the assessee's research and development unit, and the departmental record did not displace the contention that they were laboratory glassware. The objection founded on exclusionary notes in the Brussels Tariff Nomenclature could not prevail because those notes are not part of the Customs Tariff Act, 1975. At most, the BTN may have persuasive value, but it cannot be engrafted into the tariff so as to override the wording of the Act where no corresponding exclusion exists.

Conclusion: The classification claimed by the assessee under Heading 70.17/18 was accepted, and the contrary assessment under Heading 70.21 was not sustained.

Final Conclusion: The appeal succeeded, the assessment was set aside, and the assessee obtained consequential relief.

Ratio Decidendi: Explanatory notes from another tariff system may assist interpretation only as a persuasive aid and cannot be imported to control classification under the Customs Tariff Act, 1975 in the absence of a corresponding statutory exclusion.
