4411.12.90.90 - Other

This classification, HTS Code 4411.12.90.90, covers "Other" medium density fiberboard (MDF) that does not exceed 5 mm in thickness. Specifically, it captures MDF products that do not fit into more narrowly defined subcategories within the "Other" designation. This generally includes MDF sheets or panels intended for general purposes, where specific finishing, treatment, or intended use is not otherwise specified by a more particular HTS subheading.

This category is distinguished from its sibling, 4411.12.90.10, which is reserved for "Standard wood molding." While both fall under the broader umbrella of medium density fiberboard not exceeding 5 mm in thickness, this subheading is for general MDF, whereas the sibling is for molded profiles. Therefore, the key differentiator lies in the form and specific function of the product; this category is for flat sheets or panels, not shaped molding.

As this is a leaf node, there are no further subcategories. Classification into this subheading is determined by the exclusion from more specific classifications within the broader Chapter 44, particularly those for finished or specialized wood articles. The primary criteria for inclusion here are that the material is medium density fiberboard, does not exceed 5 mm in thickness, and is not specifically described or categorized elsewhere in the tariff schedule.
