4421.91.30.00 - Consisting of wooden frames in the center of which are fixed louver boards or slats, with or without their hardware

This HTS subheading, 4421.91.30.00, specifically classifies wooden frames containing fixed louver boards or slats, regardless of whether hardware is included. These articles are designed for purposes such as window coverings, decorative screens, or room dividers, where the characteristic slatted design is a defining feature. The key distinguishing element is the presence of fixed louver boards within a wooden frame structure.

It is important to distinguish this category from its sibling, 4421.91.40.00, which covers "Other" articles of wood of bamboo. While both fall under the broader category of "Of bamboo," subheading 4421.91.30.00 is precisely for the louvered frame construction. Other wooden articles made from bamboo that do not fit this specific description, such as solid bamboo panels or decorative bamboo items without the louvered structure, would be classified under the sibling category.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the focus remains on correctly identifying goods that meet the criteria of being wooden frames with fixed louver boards or slats. For classification purposes, examiners will look for articles where the primary function and construction involve this specific arrangement of slatted wooden elements within a frame.
