4410.90.00.00 - Other

This HTS category, "Other," under HTS code 4410.90.00.00, serves as a residual classification for particle board, oriented strand board (OSB), and similar composite wood or ligneous materials. These materials are characterized by being agglomerated with resins or other organic binding substances. This designation encompasses boards that do not fit into more specific subheadings within heading 4410, which primarily deals with wood-based boards.

While the parent heading 4410.90 specifically refers to "Other" materials, this particular subheading "Other" at 4410.90.00.00 captures composite boards made from wood or other ligneous materials that are not classified under the "Of wood" sibling category (which would typically denote boards primarily composed of wood particles, strands, or wafers specifically). Therefore, this "Other" subheading would likely apply to composite boards where the ligneous material is not solely or predominantly wood, but could include other plant-based fibers or materials, provided they meet the criteria of particle board, OSB, or similar board construction and are agglomerated with organic binders.

Given that this is a leaf node, there are no further subcategories. Classification within this specific code hinges on the absence of a more precise classification elsewhere within heading 4410. Importers and exporters should ensure that the materials in question are indeed composite boards of the described nature and do not qualify for more specific classifications based on material composition or manufacturing process that might exist in other HTS headings.
