Import Tips & Compliance
• Determine whether the bearing is classified as a complete bearing (heading 8482) or as ceramic parts (6909.19.90)
• If the ceramic balls are imported separately, ensure they are fired and document their technical use
• Verify the proportion of ceramic versus metal components, as this may affect classification
