Import Tips
• Include surface finish specifications (Ra values) in documentation to justify precision bearing classification
• Avoid bulk packaging declarations; specify retail-for-equipment use to prevent parts tariff shifts
• Certify compatibility with Czochralski crystal processing equipment per statistical notes
