Import Tips
• Ensure the bearings are fired after shaping and not merely sintered at low temperatures, as Chapter 69 requires firing
• Provide documentation on the laboratory or chemical analysis application to justify the technical use classification
• Verify that the bearings are not part of a larger machine that might be classified elsewhere
