Import Tips
• Obtain chemical analysis confirming S-glass (high silica content) to differentiate from E-glass; declare exact twist and yield accurately
• Avoid bundling with resins to prevent set classification under 7019.90; common pitfall is undervaluing based on weight rather than composite value
