HS Code for Electronic grade silicon

Electronic grade silicon is classified under HS code 2804.61. This classification is found in Chapter 28, which covers inorganic chemicals and precious metal compounds. Heading 2804 includes hydrogen, rare gases, and other non-metals. The specific subheading 2804.61 is reserved for silicon containing by weight not less than 99.99% of silicon. This extreme level of purity is the defining characteristic of "electronic grade" or "semiconductor grade" silicon, as even minute impurities can significantly alter the electrical properties of the material. This silicon is typically traded in the form of polycrystalline chunks or unworked ingots. The classification is strictly based on the chemical purity threshold, making it a critical code for the semiconductor supply chain and the manufacturing of integrated circuits and solar cells.

Products Included

• Polycrystalline silicon (99.99%+ purity)
• Unworked monocrystalline silicon ingots
• High-purity silicon chunks for Czochralski growth
• Semiconductor-grade silicon raw material
• Ultra-pure silicon for photovoltaic applications

Common Misclassification

Electronic grade silicon is frequently confused with HS code 2804.69, which covers silicon with a purity of less than 99.99% (often referred to as metallurgical grade silicon). Another significant misclassification is HS code 3818.00, which covers chemical elements doped for use in electronics, in the form of discs, wafers, or similar forms. If the silicon has been doped with elements like boron or phosphorus and sliced into wafers, it must be moved from 2804 to 3818.

FAQ

What is the HS code for electronic grade silicon?

The HS code for silicon with a purity of at least 99.99% is 2804.61.

When does silicon move from 2804 to 3818?

Silicon moves to HS code 3818 when it has been doped for electronic use and is shaped into wafers, discs, or similar forms ready for semiconductor fabrication.
