9027.90.59.10 - Of articles of subheading 9027.10.20 🖩

This HTS classification, 9027.90.59.10, encompasses specific parts and accessories for electrical instruments and apparatus used in physical or chemical analysis, as well as those for measuring or checking quantities of heat, sound, or light. Crucially, these parts and accessories are designated for articles falling under subheading 9027.10.20, which typically covers gas or smoke analysis apparatus. Therefore, this category is for components that are not parts of microtomes but are integral to the functioning of these particular electrical analytical instruments.

Within the broader category of "Parts and accessories" under 9027.90, this specific subheading is distinguished from its sibling, 9027.90.59.95, which serves as a residual category for all other unspecified parts and accessories of electrical instruments and apparatus within the 9027.90.59 enumeration. The "Other" designation here implies a further refinement beyond general electrical components, pointing towards parts specifically designed for the gas or smoke analysis applications identified in the parenthetical description.

As a leaf node, this classification does not have further subcategories. The classification is determined by the specific application of the part or accessory in relation to the gas or smoke analysis apparatus described in subheading 9027.10.20. Importers and exporters should ensure that the parts and accessories in question are indeed intended for, and physically suitable for integration into, such analytical equipment to correctly utilize this HTS code.
