4411 - Fiberboard of wood or other ligneous materials, whether or not bonded with resins or other organic substances:
Sub-classifications
Overview
Chapter 44 of the Harmonized Tariff Schedule (HTS) encompasses a wide array of wood and articles made from wood. Within this chapter, heading 4411 specifically classifies fiberboard of wood or other ligneous materials. This category includes panels, sheets, or boards manufactured by dry or wet processes, where wood particles or fibers are bonded together using resins or other organic substances. The key characteristic of goods under this heading is their composition as composite wood products formed from reconstituted wood material.
This heading is distinguished from other headings in Section IX by its focus on manufactured wood panels rather than raw lumber, sawn wood, or finished articles like furniture or doors, which fall under different HTS categories. Unlike solid wood, fiberboard is a panel product where the wood is broken down into fibers or particles and then reformed. It is also distinct from other composite wood products like particleboard or plywood, which have different manufacturing processes and internal structures.
Heading 4411 is further subdivided to provide greater specificity in classification. The subcategories typically differentiate based on the density of the fiberboard, such as Medium Density Fiberboard (MDF), which is characterized by a specific density range and is widely used in furniture and cabinetry. Other fiberboards that do not meet the criteria for specific density classifications are grouped under a general "Other" category. These subheadings allow for precise tariff treatment based on the technical specifications and intended applications of the fiberboard.
