Ferrosilicon Alloy Pig Iron
Alloy pig iron containing 10-30% silicon, produced in pig form for silicon addition in steel production and deoxidation. Falls under HTS 7201.50.30.00 as spiegeleisen-type alloy pig iron per Chapter 72 notes for alloyed primary castings.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If silicon >55% by weight
High-silicon ferrosilicon products classified as ferroalloys under 7202, not as alloy pig iron base.
If low silicon under alloy definition
If silicon insufficient for alloy classification, treated as non-alloy pig iron.
If remelted and cast into different primary forms
Remelted pig iron granules or other granulated forms shift to 7207 heading.

Import Tips & Compliance
• Submit chemical analysis reports showing silicon content to confirm alloy status and prevent reclassification
• Verify no 'further working' like coating occurred, as per Chapter 72 note, which would move to 7206+
• Check for uniform pig shape; irregular lumps may raise questions on 'primary forms' status

Ferromanganese Alloy Pig Iron
Pig iron alloyed with high manganese content, cast into pigs for use in steelmaking to add manganese and deoxidize melts. Classified under HTS 7201.50.30.00 as alloy pig iron due to its manganese addition exceeding basic pig iron composition, meeting Chapter 72 definitions for alloyed primary forms.
Ferrochrome Alloy Pig Iron
Pig iron alloyed with chromium (5-15%) cast in pig form, used primarily for producing stainless steels. HTS 7201.50.30.00 covers this as alloy pig iron, distinct from high-carbon ferrochrome ferroalloys.
Spiegeleisen Pig Iron
High-manganese spiegeleisen pig iron (20-35% Mn), cast in pigs for mirror-like fracture appearance and steel alloying. Specifically named under HTS 7201.50 as alloy pig iron/spiegeleisen primary form.
Nickel-Bearing Alloy Pig Iron
Pig iron with 2-5% nickel addition, cast into primary pig form for specialty steel and alloy production. Classified HTS 7201.50.30.00 as alloy pig iron due to nickel alloying beyond basic composition.
Molybdenum Alloy Pig Iron
Alloy pig iron containing 0.5-2% molybdenum, produced in pig castings for high-strength steel applications. Meets HTS 7201.50.30.00 for alloy pig iron primary forms, aligning with tool steel precursor compositions.
Vanadium Alloy Pig Iron
