Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2804.61.00Higher: 50% vs 15.5%

If 99.99% pure or greater

Pure silicon (99.99%+) for semiconductor/electronics falls under specific 'pure' subheading.

3818.00.00Higher: 50% vs 15.5%

If doped for electronics and cut into wafers/discs

Doped silicon in worked forms like wafers shifts to artificial resins chapter per Chapter 28 notes.

3824.99Lower: 15% vs 15.5%

If chemically defined but mixed with other substances exceeding tolerances

Mixtures not purely elemental silicon may classify as chemical preparations.

Import Tips & Compliance

Verify purity levels and obtain Certificate of Analysis (CoA) to confirm elemental silicon classification under Chapter 28

Ensure MSDS documentation highlights non-radioactive, non-doped status to avoid reclassification
