Lightweight HDF Underlayment 5mm from Japan
High-density fiberboard variant engineered to 0.49 g/cm³ for flooring underlayment, providing moisture resistance and sound dampening. Falls under HTS 4411.94.00 for low-density fiberboard of wood, despite 'HDF' name, due to measured density ≤0.5 g/cm³.

Import Tips
• Submit lab density measurements; naming as 'HDF' risks scrutiny for 4411.92 classification
• Include moisture content specs and TSCA certification for floor underlayment
• Declare if tongue-and-groove edged, but remains fiberboard unless assembled
