Import Tips
• Verify the pellets are in primary form (e.g
• pellets, granules) and not further worked, as this affects classification
• Keep records of the polymer composition to demonstrate the 95% comonomer threshold
• If the pellets contain additives like stabilizers or colorants, ensure they do not alter the classification under subheading notes
