Import Tips
• Include thermal expansion data in documentation to prove high-purity fused silica suitable for 1000°C+ applications
• Avoid declaring as 'finished tube' to prevent reclassification; specify 'unworked rod stock'
• Check for exemptions under HTSUS for scientific instrument components if end-use qualifies
