Ferrosilicon Rare Earth Master Alloy
Ferrosilicon Rare Earth Master Alloy is a ferrosilicon alloy containing 70% silicon with 1-3% rare earth elements (cerium/lanthanum) added for steel inclusion modification. It falls under tariff item 7202.29.00 as 'other' ferro-silicon because the rare earth additions place it outside standard binary ferro-silicon classifications. This alloy improves fatigue resistance in steel by modifying non-metallic inclusions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the rare earth content is below 1% and the silicon content is 55-80% by weight
Standard ferro-silicon with silicon content between 55% and 80% falls under this subheading, which may apply if the rare earth elements are considered incidental.
If the rare earth elements exceed 10% by weight, making it a complex ferro-alloy
Ferro-alloys with other elements exceeding the thresholds in Chapter Note 1(c) may be classified as other ferro-alloys.

Import Tips & Compliance
• Ensure the rare earth content (Ce/La) is clearly documented in the commercial invoice and certificate of analysis, as CBSA may verify the alloy composition
• Confirm the product meets the ferro-alloy definition in Chapter Note 1(c) of Chapter 72, including iron content of 4% or more by weight
• Consider requesting an advance ruling from CBSA if you are unsure about the classification of the rare earth additions

Atomized Ferrosilicon Powder
Atomized ferrosilicon powder with 75% silicon content, produced by atomization and used in powder metallurgy and welding electrodes. It retains the essential character of ferrosilicon as a ferro-alloy, and atomization does not alter its classification under this tariff item.
Atomized Ferrosilicon Powder 75%
Atomized ferrosilicon powder 75% is a finely atomized ferrosilicon powder with 75% silicon content, used in powder metallurgy and as a raw material for silicon-based compounds. Despite its powder form, it is classified under tariff item 7202.29.00 as 'other' ferro-silicon, as the powder form is not considered 'further working' per the chapter notes.
Crushed Ferrosilicon 10-50mm
Crushed ferrosilicon 10-50mm is crushed ferrosilicon lumps sized 10-50mm from 75% standard grade, optimized for submerged arc furnace feeding. It remains classified under tariff item 7202.29.00 as 'other' ferro-silicon, as crushing is not considered 'further working' per the chapter notes.
Ductile Iron FeSiMg 12% Magnesium Alloy
Ductile iron FeSiMg 12% magnesium alloy is a specialty ferrosilicon magnesium alloy containing 12% magnesium, used as a nodulizing agent in ductile iron production. It is supplied in standard foundry granules. This product falls under tariff item 7202.29.00 as 'other' ferro-silicon because its magnesium content exceeds 2% by weight, which is not covered by other subheadings of heading 72.02.
