HS Code for Wood wool

Wood wool is classified under HS code 4405.00. This heading is unique because it is a single-level heading that specifically covers both wood wool and wood flour. Wood wool consists of thin, narrow, curly, or twisted slivers of wood, usually produced from logs by specialized paring machines. It is distinct from ordinary wood shavings because the slivers are of a uniform thickness and width and are tangled together into a fibrous mass. The classification is based on the physical form of the wood rather than the species. Under the Harmonized System, wood wool is recognized primarily for its utility in protective packaging, as a stuffing material in upholstery, or as a raw material for the manufacture of wood-wool boards (often bonded with cement). Because it is a manufactured product of specific dimensions, it is excluded from the categories of wood waste or fuel wood. The classification remains 4405.00 regardless of whether the wood wool is dyed or treated for fire resistance, as long as it retains its essential character as wood wool.

Common Misclassification

Wood wool is often misclassified under HS code 4401.21 or 4401.22, which covers wood chips or particles. However, chips are generally flat and rigid, whereas wood wool is fibrous and flexible. It is also sometimes confused with HS code 4401.31 (wood pellets) or 4401.39 (other wood waste and scrap). While wood wool may be made from waste wood, its specific processing into uniform slivers moves it into heading 4405. Finally, wood flour (fine powder) is also in 4405.00, but it is physically distinct from the fibrous wool.
