J82760 · 2003-04-02 — The tariff classification of an iridium crucible for crystal growth apparatus from Japan
of Sanford, Florida you requested a tariff classification ruling. Your client produces optical crystals for medical diagnostic and electro-optical applications using a crystal growth machine. The machine requires a special high melting temperature container or crucible to hold the molten ingredient of the optical crystal. A crystal is essentially pulled from the melt Because of the need to be chemically inert and tolerate temperatures up to 2200 Celsius, the only metal that can satisfy such condition is iridium which has a melting point of 2460 Celsius. The iridium crucible, which has to be…
