4411.93.90 - Other

This classification, HTS Code 4411.93.90, encompasses fiberboard of wood or other ligneous materials that falls within a specific density range. The defining characteristic here is that the fiberboard has a density exceeding 0.5 g/cm³ but not exceeding 0.8 g/cm³. It further refines the "Other" category within this density bracket, excluding fiberboard that is specifically surface-covered, except for those that have undergone oil treatment.

Distinguishing this category from its sibling, 4411.93.60.00, is crucial. While both are within the same density range and are not surface-covered, this current node specifically excludes fiberboard that has been oil-treated. Therefore, if the fiberboard in question has had its surface treated with oil, it would not fall under this 4411.93.90 classification.

This node serves as a further subdivision of fiberboard meeting the established density and surface treatment criteria. The existing subcategories, 4411.93.90.10 ("Standard wood molding") and 4411.93.90.90 ("Other"), indicate that further distinctions are made based on the intended use or specific form of the fiberboard beyond the general density and surface characteristics. This allows for more precise classification of specialized wood products.
