Atomized Ferrosilicon Powder
Finely atomized ferrosilicon powder (75% Si) used in powder metallurgy and welding electrodes. Still classified as ferrosilicon under HTS 7202.29.00 since atomization doesn't change its essential ferroalloy character. Particle size typically 100-200 mesh.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically for welding electrodes
Ferroalloys prepared and packaged for electrode manufacture may be classified as welding preparations.
If treated as chemical additive
Powdered forms used purely chemically might fall under prepared chemical binders.
If low silicon powder variant
Silicon content still governs primary ferrosilicon classification even in powdered form.
