Import Tips

Verify weight exceeds 150 g/m² with lab testing to confirm classification in 5603.94.10; lighter nonwovens shift to 5603.93

Provide mill test reports showing nonwoven construction and no visible plastic/rubber embedding to avoid reclassification to Chapter 39

Label as 'floor covering underlay' and include end-use declaration to prevent customs disputes over general-purpose nonwovens
