HS Code 4405.00 – Wood; wood wool and wood flour

HS code 4405.00 is the 6-digit subheading for wood, wood wool and wood flour. It is used for wood wool for packaging, wood wool for animal bedding, wood flour for plastic fillers, wood flour for composites and wood flour for cleaning products.

What HS 4405.00 covers

This HS code covers highly processed wood materials: wood wool and wood flour. Wood wool, also known as excelsior, consists of thin, curled strands of wood, primarily used for packaging, insulation, and animal bedding due to its cushioning and absorbent properties. Wood flour is finely ground wood, a powder-like material used extensively as a filler in plastics, composites, wood-plastic composites, and as a mild abrasive or absorbent. These products represent a significant 'waste-to-value' stream in the timber industry, utilizing sawmill by-products. Major importers and exporters are industrialized nations with strong manufacturing sectors that require these materials for various industrial applications. The trade is driven by industrial demand for sustainable fillers and packaging solutions.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
