Crystal Growth Crucible Holder from Mexico
A crystal growth crucible holder is a high-purity graphite or quartz component that precisely positions the crucible in Czochralski furnaces during silicon pulling. It is an essential part of crystal grower machines classified under heading 84.28, and therefore falls under tariff item 8431.39.00 as 'other' parts.

Import Tips
• Provide evidence that the holder is solely or principally used with crystal grower machinery of heading 84.28
• Include material certifications (e.g
• graphite purity) for the CBSA to verify classification
• Consider duty deferral programs if the holder is for use in Canadian manufacturing
