Last updated: August 2026 dataWood wool (excelsior) consists of long, fine wood shavings used as protective packaging, horticultural growing media, and acoustic panel fill, while wood flour is a finely milled wood powder used as a filler in plastics, rubber, explosives, and wood-plastic composites. These are distinct industrial inputs with separate end-use supply chains despite sharing a single SITC heading. Wood flour's role as a functional filler in thermoplastic composites — including decking and automotive parts — has driven steady industrial demand, and particle size distribution is the key specification variable that determines suitability for a given application.

Wood flour for thermoplastic composites is typically specified by mesh size (e.g., 40–120 mesh), moisture content (usually below 5%), and species (softwood vs. hardwood), as these variables affect flow properties, surface finish, and mechanical performance of the final composite. Importers should request mill certificates confirming particle size distribution and moisture content for each shipment.
Wood wool used as cushioning or protective packaging in international shipments may be subject to ISPM 15 phytosanitary treatment requirements if it is made from raw or minimally processed wood. However, wood wool that has been manufactured through a process that eliminates pest risk (such as kiln drying to specified temperatures) may be exempt. Importers should confirm treatment status with their supplier and USDA APHIS guidance before shipment.
