8422.90 - Parts:

This HTS category, 8422.90, encompasses **parts and accessories** for the machinery classified under heading 8422. This heading broadly covers a variety of machines used for packaging, filling, sealing, labeling, and cleaning containers, as well as dishwashing machines. Therefore, 8422.90 serves as a catch-all for components that are specifically designed to be used with these primary machines, but are not the machines themselves.

It is crucial to distinguish this category from its sibling headings, which classify the complete machines. For example, while 8422.20.00.00 covers machinery for cleaning or drying bottles, 8422.90 would include the pumps, nozzles, or conveyor belts that are integral to such cleaning machines but are imported or classified separately. Similarly, parts for dishwashing machines fall under 8422.90, whereas complete dishwashing machines would be classified under the preceding, unnumbered subcategory of 8422.

The subcategories within 8422.90 provide further specificity for these parts. For instance, 8422.90.11.00 and 8422.90.21.00 identify parts for specific types of packaging and sealing machines. The residual category, 8422.90.91, is for all other parts and accessories not specifically enumerated, ensuring comprehensive coverage for components used with the diverse machinery described in heading 8422. The key classification criterion here is the function and intended use of the part in relation to the parent machinery.
