4411.13.30.00 - Other 🖩

This HTS category, 4411.13.30.00, specifically covers "Other" medium density fiberboard (MDF) that is of a thickness exceeding 5 mm but not exceeding 9 mm. The defining characteristic for inclusion here is that these fiberboard panels are manufactured with continuous tonguing, grooving, or rabbetting along any of their edges. Crucially, these specific edge treatments must render the panels dedicated for use in the construction of walls, ceilings, or other building parts, indicating a functional design for assembly within building structures.

Distinguishing this category from its sibling, 4411.13.20.00, is the absence of lamination with synthetic resins or impregnation with such resins as the primary distinguishing factor. While this category may have undergone treatments, the core definition here hinges on the specialized edge profiling and intended application in construction, rather than a specific method of bonding or impregnation that defines the sibling category.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification within 4411.13.30.00 relies on confirming that the MDF meets the specified thickness range (over 5 mm and up to 9 mm), possesses continuous tongued, grooved, or rabbetted edges, and is demonstrably designed for and intended for use in building construction applications. This ensures that only fiberboard panels meeting these precise physical and functional criteria are classified under this code.
