PVC Foam Board Sign Blank from Japan
A rigid sheet made from cellular polyvinyl chloride (PVC) foam, commonly used as a lightweight substrate for signage and displays. It falls under HTS 3921.12.5000 as 'other' cellular plates, sheets of polymers of vinyl chloride, not rigid flexible or flexible sheets. The cellular structure provides insulation and buoyancy properties.

Import Tips
• Verify cellular structure via density testing (<0.96 g/cm³) to confirm classification under 3921.12 vs non-cellular 3920.12
• Provide detailed monomer composition certificates showing ≥95% vinyl chloride units per subheading note (a)(1)
• Avoid misclassification as rigid PVC sheet (3921.12.1100) by documenting foam expansion process
