Quartz Half-Wave Retarder Plate from China
Mounted crystalline quartz plate that introduces a half-wavelength phase shift for polarization control in laser systems and microscopes. HTS 9002.90.95.00 covers this as a mounted optical element of quartz (silica) for scientific instruments. Used in applications requiring precise light manipulation.

Import Tips
• Specify wavelength optimization and mounting tolerances in technical specs
• Avoid Chapter 70 glass classification by proving crystalline quartz construction
• Include calibration certificates for duty preference programs
