Ferrosilicon Rare Earth Master Alloy from United States
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.

Import Tips
• 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
