8424.90 - Parts:

HTS Code 8424.90 encompasses parts and accessories for the machinery classified under heading 8424. This heading broadly covers mechanical appliances used for projecting, dispersing, or spraying liquids or powders, including fire extinguishers, spray guns, and jet projecting machines. Therefore, 8424.90 is specifically for components that are integral to the functioning of these broader categories of equipment, rather than the complete machines themselves.

Distinguishing 8424.90 from its sibling categories is crucial. While siblings like 8424.10 (fire extinguishers) and 8424.20 (spray guns) classify the complete machines, 8424.90 focuses solely on the individual parts that make up these machines. For instance, a complete portable fire extinguisher would fall under 8424.10, whereas its hoses, nozzles, or release valves would be classified under 8424.90, provided they are not specifically classified elsewhere as finished articles.

This category is further subdivided to account for the diverse nature of the parent machinery. Subcategories like 8424.90.05.00 (Of fire extinguishers) and 8424.90.20.00 (Of sand blasting machines) allow for more precise classification based on the specific type of apparatus the part belongs to. The general category 8424.90.90 (Other) serves as a catch-all for parts that do not fit into the more specific subheadings, ensuring comprehensive coverage within the broader scope of heading 8424.
