Products classified under Tariff item 7201.50
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.
7201.50.00Ferromanganese 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.
7201.50.00Ferrosilicon 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.
7201.50.00Foundry-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.
7201.50.00High-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%.
7201.50.00Mirror 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.
7201.50.00Molybdenum Alloy Pig Iron
Molybdenum alloy pig iron containing 0.5-2% molybdenum, cast in pig form for high-strength steel applications. It is classified under tariff item 7201.50.00 as alloy pig iron because the molybdenum content exceeds the threshold for pig iron but does not qualify as a ferro-alloy.
7201.50.00Nickel-Bearing Alloy Pig Iron
Nickel-bearing alloy pig iron with 2-5% nickel addition, cast into primary pig form for specialty steel and alloy production. It is classified under tariff item 7201.50.00 as alloy pig iron because the nickel content exceeds the limit for pig iron.
7201.50.00Silico-Manganese Alloy Pig Iron
Silico-manganese alloy pig iron with silicon (10-20%) and manganese (60-70%), cast in pigs as a cost-effective steel alloying alternative. It is classified under tariff item 7201.50.00 as alloy pig iron because it is pig iron alloyed with silicon and manganese, not a ferro-alloy.
7201.50.00Silico-Manganese Spiegeleisen Block
Silico-manganese spiegeleisen block cast with elevated silicon and manganese content, serving as a nodulizing agent in cast iron production. It is classified under tariff item 7201.50.00 as spiegeleisen because the manganese content is within 6-30%.
7201.50.00Spiegeleisen Pig Iron
Spiegeleisen pig iron with 20-35% manganese, cast in pigs for its mirror-like fracture appearance and steel alloying. It is specifically named under tariff item 7201.50.00 as spiegeleisen, a type of pig iron with high manganese content.
7201.50.00Standard Spiegeleisen Sows
Standard spiegeleisen sows, large sow-shaped castings of high-silicon, high-manganese pig iron used in foundries for gray iron production. This primary form product is classified under tariff item 7201.50.00 as spiegeleisen, distinct from other alloy pig irons.
7201.50.00Vanadium Alloy Pig Iron
Vanadium alloy pig iron with 0.5-1.5% vanadium, cast in standard pig form for micro-alloyed high-strength steels. It is classified under tariff item 7201.50.00 as alloy pig iron because the vanadium content exceeds the threshold for pig iron.
