Products classified under HTS 2804.61.00.00
Polycrystalline Silicon Ingots
High-purity polycrystalline silicon ingots with 99.99% silicon content, used primarily in the production of photovoltaic cells for solar panels. This product falls under HTS 2804.61.00.00 as it is chemically defined elemental silicon meeting the purity threshold specified in the heading for nonmetals.
Monocrystalline Silicon Chunks
Chunks of monocrystalline silicon containing at least 99.99% silicon by weight, serving as raw material for semiconductor and solar wafer slicing. Classified under HTS 2804.61.00.00 as high-purity elemental silicon in unworked form per Chapter 28 definitions.
Electronic-Grade Polysilicon Rods
Polysilicon rods with 99.99+% purity silicon content, produced via Siemens process for semiconductor manufacturing. This chemically defined silicon meets HTS 2804.61.00.00 criteria as high-purity elemental nonmetal in cylindrical form.
Solar-Grade Silicon Bricks
Rectangular silicon bricks of 99.99% purity cut from polysilicon ingots, used directly for solar wafer production. Falls under HTS 2804.61.00.00 as it qualifies as high-purity elemental silicon before final wafer slicing.
Hyper-Pure Silicon Cylinders
Cylindrical hyper-pure silicon forms containing no less than 99.99% silicon, intended for advanced semiconductor fabrication. Classified in HTS 2804.61.00.00 as chemically defined high-purity silicon in unworked rod/cylinder form allowed by Chapter 28.
