Import Tips
• Provide Bayer abrasion ratio test results (>4.0 for glass) proving durable coating on glass substrate
• Declare coating thickness (<5 microns typical) to confirm not substantial material addition changing composition
• Avoid 'safety glass' terminology that might trigger laminated glass classification under Chapter 70
