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 a silicon content of 0.25%. It is used as an additive in electric arc furnace steelmaking to impart strength and toughness to high-strength low-alloy steels.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the niobium content falls below 60% or impurities exceed the specified limits
Ferro-alloys not elsewhere specified or included under heading 72.02 may be classified as 'Other' if they do not meet the specific criteria for ferro-niobium.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the product's chemical composition (niobium, phosphorus, sulfur, silicon) is documented in the commercial invoice to support classification under 7202.93.00
• Verify that the lumps meet the physical form criteria for ferro-alloys (pigs, blocks, lumps, or similar primary forms) to avoid reclassification
• Consult the CBSA's tariff classification advice service for binding rulings on borderline compositions
