Import Tips
• Ensure the retaining ring is classified as a part of machinery under heading 84.87, not as a consumable of plastics under Chapter 39
• Declare the material composition (e.g
• PEEK, PTFE) to avoid misclassification
• Keep records of the machinery it is designed for in case CBSA requests justification
