4411.13.90.90 - Other

This classification, HTS Code 4411.13.90.90, pertains to "Other" fiberboard products that fall under the broader category of medium-density fiberboard (MDF) with a thickness exceeding 5 mm but not exceeding 9 mm. Specifically, it captures MDF panels that do not fit into more specific subcategories within this thickness range. This designation is for those items where specific physical attributes, intended use, or manufacturing processes are not otherwise detailed in the preceding subheadings.

Distinguishing this category from its sibling, "Standard wood molding" (4411.13.90.10), is crucial. While both are at the same hierarchical level, this "Other" category is not designed for pre-formed wood molding pieces. Instead, it serves as a residual classification for general MDF panels of the specified thickness that do not possess the specific shaping and intended application of moldings.

As this is a leaf node, there are no further subcategories to introduce. Therefore, classification within 4411.13.90.90 relies on excluding items that would otherwise fit into more precisely defined categories. Importers and exporters should carefully review the preceding subheadings to ensure the product does not meet the criteria for any more specific classification before assigning it to this general "Other" category for medium-density fiberboard.
