Fused Silica Ultraviolet Mirror from China
A fused silica substrate mirror with dielectric coatings optimized for ultraviolet wavelengths, used in lithography systems. It is an unmounted optical element, not incorporated into a larger assembly, and therefore falls under tariff item 9001.90.00 for other optical elements of any material.

Import Tips
• Ensure the mirror is truly unmounted and not part of a larger optical assembly, as that could change classification
• Keep technical specifications (substrate, coatings, wavelength) in your commercial invoice to support the tariff classification
• Verify whether the goods qualify for any preferential tariff treatment under Canada's free trade agreements
