Import Tips
• Provide Raman shift performance specifications and compatible laser wavelength data for customs validation
• Include end-user statements confirming use solely with chapter 90 spectrometers, not general fiber applications
• Declare optical fiber content accurately to avoid scrutiny under chapter 85 telecommunications headings
