Import Tips
• Provide path length tolerance certificates (±0.01mm) proving suitability for quantitative polarimetry
• Include temperature jacket specifications if equipped, documenting integration with polarimeter systems
• Separate cells from complete polarimeter sets to avoid set classification under 9027.50
