8424.20 - Spray guns and similar appliances:

This HTS category, 8424.20, specifically encompasses spray guns and similar appliances designed for projecting, dispersing, or spraying liquids or powders. This includes a wide array of hand-held or powered devices utilized for applications such as painting, coating, or applying various substances in a fine mist or stream. The primary function of these appliances is to atomize a liquid or disperse a powder into a controlled spray pattern.

Distinguishing this category from its siblings, 8424.10 covers complete fire extinguishers, while 8424.30 pertains to steam or sand blasting machines. The "Agricultural or horticultural sprayers" and "Other appliances" entries at this level would capture sprayers with specific end-uses in agriculture or general-purpose spray devices not fitting the specific definition of a spray gun. Category 8424.90 is reserved for parts and accessories of all the machinery covered under heading 8424.

The subcategories under 8424.20 further refine the classification. 8424.20.10.00 specifically identifies simple piston pump sprays and powder bellows, differentiating them by their pumping mechanism and form. The remaining items, classified under 8424.20.90.00, cover all other spray guns and similar appliances that do not fall into the aforementioned specific piston pump category, thereby providing a residual classification for the broader range of spray devices within this heading.
