4411.92.30.00 - Tileboard which has been continuously worked along any of its edges and is dedicated for use in the construction of walls, ceilings or other parts of buildings

This HTS classification, 4411.92.30.00, specifically designates tileboard manufactured from wood or other ligneous materials. The material must be bonded with resins or other organic substances and has undergone continuous working along its edges. Crucially, this tileboard is intended for use in the construction of walls, ceilings, or other building components. The definition emphasizes its finished nature and its specific application within the construction sector.

While sibling categories at this level also fall under "Other" within the broader classification of fiberboard, this particular subcategory is distinguished by its specific form and intended use. Unlike other "Other" categories which might encompass undimensioned fiberboard or those not explicitly designed for construction finishing, 4411.92.30.00 is precisely for tileboard ready for installation in building structures. The continuous edge working is a key differentiator, suggesting a product ready for assembly or display as a finished surface.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification decisions at this level therefore rely on a thorough understanding of the physical characteristics (continuous edge working, material composition, bonding agents) and the intended application (construction of walls, ceilings, etc.) of the fiberboard product. Any fiberboard meeting the density requirement and not fitting into more specific classifications but matching these criteria would be assigned to this code.
