Import Tips
• Submit material data sheets showing compatibility with silicon nitride ceramic balls to support ball bearing classification
• For fab equipment imports, segregate bearing parts from full machines to prevent Chapter 84/90 reclassification
• Declare surface finish specs (Ra < 0.1 μm) which distinguish precision races from general steel rings
