Noryl Foam Sheets from United States
Noryl foam sheets are cellular sheets made from modified polyphenylene oxide (PPO), a high-performance engineering plastic known for heat resistance and dimensional stability. They are classified under 3921.19.00 because the chemical modification of the polymer places them in the 'other plastics' category, as no specific subheading covers modified PPO.

Import Tips
• Document the chemical modification process and the base polymer to support classification under 'other plastics'
• Confirm the sheets are cellular (foamed) and not solid, as solid sheets would fall under different tariff items
• Keep technical datasheets available for CBSA inspection
