Import Tips

• Verify density certification (0.35-0.5 g/cm³) and bitumen impregnation content via lab testing to confirm HTS 4411.94.00.30 classification

• Include manufacturer's specs and impregnation process documentation to avoid misclassification as plain fiberboard

• Check for formaldehyde emission compliance under TSCA Title VI for composite wood products
