OVD Outside Vapor Deposition Preform Machine from Japan
Outside Vapor Deposition (OVD) machine that flames hydrolyzes silicon tetrachloride to deposit soot on a ceramic target, building preforms for optical fibers. Multiple passes create graded index profiles. Specifically classified in HTS 8475.21.00.00 for optical fiber preform production.

Import Tips
• Provide evidence of flame hydrolysis capability for distinguishing from MCVD systems
• Ensure chemical handling certifications for silicon precursors
• Note energy consumption for flame systems in efficiency declarations
