Polyetherimide Resin Granules from Japan
Polyetherimide (PEI) resin granules, such as Ultem, are high-performance aromatic polyethers in primary form. Their imide-ether structure qualifies them as 'other polyethers' under tariff item 3907.29.00, as the polyether monomer content meets the 95% threshold. These granules are used in aerospace, automotive, and high-temperature electrical applications.

Import Tips
• Ensure the granules are in primary forms (e.g
• pellets or granules) and not further worked
• Provide a material safety data sheet (MSDS) if required by CBSA
• Verify the polyether monomer content exceeds 95% to avoid reclassification
