4411.92.10.00 - Not mechanically worked or surface covered 🖩

This HTS classification, 4411.92.10.00, specifically identifies fiberboard of wood or other ligneous materials that are *not mechanically worked or surface covered*, and which have a density exceeding 0.8 g/cm³. This means the material is essentially raw fiberboard, formed by pressing wood fibers with binders, without any further processing like sanding, planing, laminating, or coating. The critical distinguishing factor here is the lack of mechanical working or surface treatment, setting it apart from other categories where such finishes are present.

Within the broader "Other" category for fiberboard, this subcategory distinguishes itself by its high density. Materials classified here are dense and compact, typically used for structural applications where strength and rigidity are paramount. The absence of surface treatments also means the material's inherent fibrous structure and density are its primary characteristics for classification at this level.

As this is a leaf node, there are no further subcategories. The classification is complete at this level, indicating that any fiberboard meeting the criteria of being of wood or other ligneous materials, not mechanically worked or surface covered, and with a density exceeding 0.8 g/cm³, will fall under this specific HTS code. Examples could include very dense, unfinished particleboard or medium-density fiberboard (MDF) that has not undergone any secondary processing.
