9008.90 - Parts and accessories:

This HTS category, 9008.90, encompasses parts and accessories specifically designed for use with the optical instruments classified under heading 9008, excluding cinematographic equipment. This includes components such as lenses, bulbs, power supplies, remote controls, mounting brackets, and internal mechanisms for image projectors (other than cinematographic), as well as photographic enlargers and reducers. The primary function of these parts and accessories is to enable the operation, maintenance, or enhancement of the main apparatus.

Distinguishing this category from its sibling, 9008.50 (Projectors, enlargers and reducers), is crucial. Heading 9008.50 covers the complete, functional apparatus itself, such as a digital projector or a photographic enlarger. In contrast, 9008.90 is strictly for the individual components and supplementary items that are not the primary device but are integral to its functionality. If a component is designed to be interchangeable and is not the core projector, enlarger, or reducer unit, it falls under the 9008.90 classification.

The subcategories within 9008.90 provide further refinement based on the specific type of apparatus the part or accessory is intended for. 9008.90.40.00 specifically covers parts and accessories for image projectors, excluding those used in cinematographic applications. The broader category 9008.90.80.00 accounts for all other parts and accessories within heading 9008 that do not fall under the more specific projector classification, ensuring comprehensive coverage for all ancillary items related to photographic enlargers and reducers, as well as other non-cinematographic optical projection devices.
