4421.99.30.00 - Consisting of wooden frames in the center of which are fixed louver boards or slats, with or without their hardware

This HTS category, 4421.99.30.00, specifically covers articles of wood that are characterized by wooden frames containing fixed louver boards or slats. These items are designed to function as blinds, shutters, screens, or shades, and the presence or absence of associated hardware does not alter their classification within this code. The defining feature is the construction of a framed unit with adjustable or fixed wooden slats.

This classification is distinct from its sibling category, 4421.99.40.00 "Other," which is a residual category for any remaining wooden articles not otherwise specified. Therefore, if an article is clearly identifiable as a wooden louvered frame intended for use as a blind, shutter, screen, or shade, it belongs here and not in the broader "Other" category at the same level.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification at this level hinges on the specific physical attributes of the wooden article: the presence of a frame and the incorporation of louver boards or slats. Examples include interior window shutters with fixed wooden louvers, decorative wooden screens with slat construction, or similar framed wooden articles designed for light control or privacy.
