9027.90.59 - Other

HTS Code 9027.90.59 encompasses a residual category for parts and accessories of electrical instruments and apparatus used for physical or chemical analysis, as well as for measuring or checking various physical properties. This classification serves as a catch-all for components not specifically enumerated under more detailed subheadings. The scope is broad, including items such as specialized cables, power supplies, housings, and mounting hardware that are integral to the operation of analyzers and measuring devices.

This category is distinguished from its siblings by its residual nature. For example, sibling 9027.90.54.00 specifically covers parts of electrophoresis instruments that do not include optical or other measuring devices, a narrow exclusion from broader electrical instrument parts. Sibling 9027.90.56, conversely, focuses on parts for specific analytical instruments (subheadings 9027.20, 9027.30, 9027.50, 9027.81, and 9027.89), meaning 9027.90.59 captures components not tied to those particular instrument types.

Within 9027.90.59, further subdivision is provided. Subcategory 9027.90.59.10 specifically addresses parts and accessories pertaining to articles classified under subheading 9027.10.20, which relates to gas or smoke analysis apparatus. The remaining parts and accessories within the broader electrical instrument context, and not falling under the specific exclusion of 9027.90.59.10, are then directed to the even more residual category 9027.90.59.95. This hierarchical structure ensures precise classification by progressively narrowing the scope of covered items.
