Import Tips
• Document graphite content percentage to ensure it remains below levels that would change material composition classification
• Provide lubrication performance test data linking yarn properties to industrial stuffing box applications
• Distinguish from carbon fiber products by providing chemical analysis confirming glass fiber base composition
