Tariff classification of plastic extruder dies: not interchangeable tools, but parts of plastic extruders under the Customs Tariff.

Imported dies for plastic extruders were held not to fall within Heading 82.05 as interchangeable tools because plastic extruders were not treated as machine tools for that tariff purpose, and the dies were usable only for one specific function rather than being replaceable by another tool to do the same work. The reference to extrusion dies in the tariff notes was read as covering dies for metals and hard plastics only, while dies for making plastic tapes from HDPE and polypropylene were outside that class. The heading was construed as explanatory of the listed items, not as extending to all dies. The dies were therefore classifiable as parts of plastic extruders under Heading 84.59(2).

Issues: Whether the imported dies for plastic extruders were classifiable under Heading 82.05 of the Customs Tariff Act, 1975 as interchangeable tools for machine tools, or under Heading 84.59(2) as parts of plastic extruders.

Analysis: The relevant tariff entry under Heading 82.05 covered interchangeable tools, including dies for wire drawing and extrusion dies for metals. The decisive question was whether plastic extruders could be treated as machine tools for that purpose. Applying the description of machine tools and the CCCN notes, the Tribunal held that the expression 'certain plastics' in the notes referred only to hard plastics, and plastic extruders used for making tapes from raw materials such as HDPE and polypropylene did not fall within that class. The dies were usable only for one specific function and could not be replaced by any other tool to perform the same job, so they were not interchangeable tools. The inclusive wording in Heading 82.05 was understood as clarifying the items expressly mentioned, not as extending the heading to all other dies. The analogy of excluded items such as spinnerets and glass-fibre dies also supported exclusion from Heading 82.05.

Conclusion: The dies were not classifiable under Heading 82.05 and were correctly classifiable under Heading 84.59(2) as parts of plastic extruders.

Final Conclusion: The assessee succeeded on the tariff classification dispute, and the departmental classification was set aside with consequential relief.

Ratio Decidendi: Dies intended for exclusive use as parts of a specific machine are not 'interchangeable tools' unless they can be used in place of another tool to perform the same function and the machine itself answers the description of a machine tool within the tariff entry.
