Import Tips
• Provide optical path length specifications and material certificates (quartz/glass) for proper HTS verification
• Label shipments clearly as 'HPLC detector parts' with model compatibility to prevent misclassification as general glassware
• Include calibration certificates to demonstrate precision instrument status during customs inspection
