Silicon Ingot for Semiconductors from Japan

High-purity monocrystalline silicon ingot, cultured via Czochralski method, weighing more than 2.5 grams, used as raw material for wafer slicing. Falls under HTS 3824.99.1900 for cultured crystals not specified elsewhere or as optical elements. Essential for electronics industry substrates.

Import Tips

Provide purity certification (e.g

>99.999% Si) and resistivity specs to confirm semiconductor-grade classification

Declare exact weight and dimensions; under-declaring risks penalties as customs weighs individually

Avoid shipping sliced wafers, which shift to HTS 3818 as semiconductor media
