Float Zone Crystal Grower RF Coil from Japan
A radio frequency induction coil used in float zone crystal pullers to melt a narrow zone of a polysilicon rod, producing high-purity monocrystalline silicon boules. This coil is a critical component of the crystal growth equipment and is specifically designed for this application. It falls under this tariff item as a part of machines used solely or principally for the manufacture of semiconductor boules.

Import Tips
• Ensure the RF coil is documented as a part of float zone crystal growth equipment, with clear specifications showing its sole use in semiconductor boule production
• Be prepared to explain to CBSA why it is not classified as a general electrical inductor, which would fall under a different heading
• Consider consulting a customs broker to confirm the correct classification and to assist with any technical documentation requirements
