8475.90 - Parts:

This HTS category, 8475.90, specifically covers *parts* intended for use with the machinery described in heading 8475. The machinery within heading 8475 is broadly categorized into two main functions: machines for assembling electric or electronic lamps, tubes, or flashbulbs in glass envelopes, and machines for manufacturing or hot working glass or glassware. Therefore, any component, accessory, or subassembly that is designed and intended to be incorporated into or used in conjunction with these specific types of machines falls under this classification.

Distinguishing 8475.90 from its sibling categories is crucial for accurate classification. The sibling categories are 8475.10, which exclusively covers the complete machines for assembling electric or electronic lamps, tubes, or flashbulbs, and the implied category for complete machines used for manufacturing or hot working glass or glassware. In contrast, 8475.90 is solely for the individual components or replacement parts of these machines, not the machines themselves. This distinction is based on the product's completeness and its functional role; if it is a constituent part rather than a fully operational machine, it belongs here.

Within the parts classification 8475.90, further subdivisions exist to provide greater specificity. Subcategory 8475.90.10.00 covers parts specifically designated for use with machines for assembling electric or electronic lamps, tubes, or flashbulbs. The residual subcategory, 8475.90.90.00, encompasses all other parts that are not exclusively for lamp assembly machines but are intended for the machinery used in the manufacturing or hot working of glass or glassware. These subcategories help to precisely identify the origin and intended application of the part within the broader scope of heading 8475.
