8475.21.00.00/Czochralski Crystal Puller for Optical Fiber Preforms/Canada

Czochralski Crystal Puller for Optical Fiber Preforms from Canada

This machine uses the Czochralski method to grow high-purity silica monocrystalline boules from which optical fiber preforms are sliced. It melts silica in a crucible and slowly pulls a seed crystal to form the boule under precise temperature control. Classified under HTS 8475.21.00.00 as it is specifically designed for producing preforms used in optical fiber manufacturing.

Import Tips

• Verify machine specifications confirm use for optical fiber preforms, as general glass working machines fall under other subheadings

• Provide technical documentation proving silica boule growth capability to avoid misclassification as wafer manufacturing equipment

• Ensure export licenses from origin country if technology involves controlled high-purity growth processes
