Products classified under Tariff item 2804.61
Electronic-Grade Polysilicon Rods
Electronic-grade polysilicon rods with a silicon content of 99.99% or higher, produced via the Siemens process for semiconductor manufacturing. These rods are chemically defined elemental silicon in an unworked form, meeting the purity threshold of tariff item 2804.61.00.
2804.61.00Hyper-Pure Silicon Cylinders
Hyper-pure silicon cylinders containing at least 99.99% silicon, intended for advanced semiconductor fabrication. These cylinders are in unworked rod or cylinder form, as required by Chapter 28 Note 8, and qualify as chemically defined elemental silicon under this tariff item.
2804.61.00Monocrystalline Silicon Chunks
Monocrystalline silicon chunks with a silicon content of at least 99.99% by weight, used as raw material for semiconductor and solar wafer slicing. These chunks are chemically defined elemental silicon in an unworked form, meeting the purity criteria of tariff item 2804.61.00.
2804.61.00Polycrystalline Silicon Ingots
Polycrystalline silicon ingots with a silicon content of 99.99% or higher, used primarily in the production of photovoltaic cells for solar panels. These ingots are chemically defined elemental silicon in an unworked form, meeting the purity threshold of tariff item 2804.61.00.
2804.61.00Solar-Grade Silicon Bricks
Solar-grade silicon bricks of 99.99% purity, cut from polysilicon ingots and used directly for solar wafer production. These bricks are chemically defined elemental silicon in an unworked form, meeting the purity criteria of tariff item 2804.61.00 before final wafer slicing.
