Import Tips
• Confirm the PPA powder's chemical composition and provide a certificate of analysis to CBSA, as semi-aromatic polyamides may be scrutinized for correct classification
• Check if the powder contains additives exceeding 1% by weight, which could affect the tariff item within 3908.90.00
• Verify whether the powder is considered a moulding composition, as that may influence the applicable duty rate
