Import Tips
• Ensure documentation specifies 'internal lamination' to differentiate from surface-impregnated papers in other headings
• Comply with US building code standards; include test reports for tensile strength and water resistance
• Avoid pitfalls by confirming it's in rolls or sheets, not cut-to-size articles which may go to heading 4823
