Import Tips & Compliance
• Verify that the manganese content is between 6% and 30% and the product is in primary form
• Provide a lab analysis to the CBSA
• Note that if the silicon content exceeds 8%, it may be reclassified as a ferro-alloy
Related Products under Tariff item 7201.50.00
Ferrochrome Alloy Pig Iron
Ferrochrome alloy pig iron, containing 5-15% chromium by weight, cast in pig form. It is used primarily as an additive in the production of stainless steels, where it introduces chromium into the melt. This product qualifies as alloy pig iron under tariff item 7201.50.00 because it is a pig iron alloyed with chromium, not a ferro-alloy.
Ferromanganese Alloy Pig Iron
Ferromanganese alloy pig iron, containing high manganese content, cast into pigs for steelmaking. It is used to add manganese and deoxidize melts. This product is classified as alloy pig iron under tariff item 7201.50.00 because it is pig iron with manganese as an alloying element, not a ferro-alloy.
Ferrosilicon Alloy Pig Iron
Ferrosilicon alloy pig iron containing 10-30% silicon, produced in pig form for silicon addition in steel production and deoxidation. It falls under tariff item 7201.50.00 as alloy pig iron because the silicon content exceeds the limit for pig iron but does not meet the definition of a ferro-alloy.
Foundry-Grade Spiegeleisen Pigs
Foundry-grade spiegeleisen pigs optimized for foundry use, with controlled manganese and silicon for consistent nodulization in ductile iron. This primary form product is classified under tariff item 7201.50.00 as spiegeleisen, a type of pig iron with high manganese content.
High-Manganese Spiegeleisen Pig
High-manganese spiegeleisen pig containing high levels of manganese and silicon, used primarily as a ferroalloy additive in steel production to enhance deoxidation and desulfurization. It falls under tariff item 7201.50.00 as spiegeleisen because the manganese content is within 6-30%.
Mirror Spiegeleisen Blocks
Mirror spiegeleisen blocks exhibiting the characteristic silvery mirror fracture, high in silicon for steel deoxidizer applications. They are classified under tariff item 7201.50.00 as spiegeleisen in primary block form, without further working.
