Last updated: April 2026 dataWood wool — commercially known as excelsior — consists of fine, curled wood shavings used for protective packaging, horticultural growing media, and acoustic panels, while wood flour is a finely milled powder used as a filler in plastics, explosives, and wood-composite products. Germany is the leading US supplier under this single-line heading (4405000000), with Ukraine and the United Kingdom also contributing. Both products are classified by their physical form rather than species, so importers must ensure that particle size and processing method align with the heading's scope rather than with wood-based panel or pellet classifications. The heading carries no mandatory admissibility review, but accurate product description on entry documents is important given the range of industrial end uses.

Wood flour is distinguished by its very fine particle size, typically passing through a specific mesh screen, and its powdery consistency. Coarser material — such as sawdust, wood chips, or wood particles — generally falls under other headings in Chapter 44. If particle size is borderline, a binding ruling request to CBP can provide certainty before importation.
Wood wool used in food-contact packaging may be subject to FDA regulations governing indirect food additives, depending on the application. For horticultural use, USDA APHIS may require documentation confirming the material has been processed to eliminate pest risk. Importers should confirm applicable requirements with the relevant agency before the first shipment.
