Low-Phosphorus Foundry Pig Iron
Pig iron cast in standard pig shapes with 0.5% or less phosphorus content, used primarily for foundry applications to produce castings. It falls under HTS 7201.10.00.00 as nonalloy pig iron in primary forms with low phosphorus for high-quality melting. The low phosphorus ensures minimal brittleness in final cast products.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phosphorus exceeds 0.5% but not over 0.65%
Higher phosphorus nonalloy pig iron shifts to 7201.50, affecting melting properties and tariff treatment.
If alloyed with elements like chromium or nickel
Ferrosilicon or other ferroalloys are classified in Chapter 72 heading 7202, not as nonalloy pig iron.
If remelted and cast into ingots or blocks
Processed into ferrocerium or other forms moves it from primary pig iron to heading 7204.

Import Tips & Compliance
• Obtain mill test certificates verifying phosphorus content ≤0.5% by weight to comply with HTS classification
• Declare exact chemical composition on entry documents; misdeclaration risks reclassification to higher-phosphorus codes
• Inspect for rust or discoloration upon arrival—no duty allowance per Chapter 72 notes
