Ferroniobium Lumps Ultra-Low P/S
Ferroniobium in lump form with a niobium content of 60-70% by weight, characterized by ultra-low phosphorus and sulfur levels (max 0.01% each) and low silicon (max 0.25%). It is used as an additive in electric arc furnace steelmaking to produce high-strength low-alloy steels, and falls under tariff item 7202.93.00 as ferro-niobium.

Import Tips & Compliance
• Ensure the product's chemical composition is documented with a mill certificate, as CBSA may verify niobium, phosphorus, sulfur, and silicon content
• Classify as ferro-niobium under 7202.93.00; if the lumps are mixed with other ferroalloys, consider separate classification
• Verify whether the product qualifies for preferential tariff treatment under a free trade agreement by providing a valid certificate of origin
