Silicon Carbide Raw Precursor
Elemental silicon lumps serving as precursor for silicon carbide (SiC) abrasive production via Acheson process. Falls under 2804.69.50.00 as nonmetal silicon not pure or semiconductor-grade.
Hyper-Pure Silicon Offcuts
Scrap offcuts from semiconductor silicon ingot trimming, repackaged for metallurgical recovery. 2804.69.50.00 as other silicon not reworked forms.
Metallurgical Grade Silicon
High-purity silicon used primarily in the production of aluminum-silicon alloys and steel additives. It is chemically defined as elemental silicon meeting Chapter 28 Note 1 requirements and classified under 2804.69.50.00 as 'other' silicon not in pure form or for semiconductor use.
Ferrosilicon Alloying Powder
Granular ferrosilicon powder (75% Si) used in foundries for deoxidation and alloying in iron casting. Classified under 2804.69.50.00 as 'other' silicon despite iron content, as silicon is principal nonmetal per HTS structure.
Chemical Synthesis Silicon Chunks
