Import Tips
• Provide thermal tolerance specs and end-use statements for semiconductor crystal growth to support plain bearing classification
• Ensure no housing attachment; loose import risks reclassification as housed bearings under 8483.30.30
• Declare graphite purity levels to avoid chemical product headings in Chapter 38
