Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If standard low-phosphorus white iron pigs
Distinction is purely phosphorus content within the same nonalloy pig iron heading.
If ferromanganese pig iron
Pig iron alloyed with manganese classifies as ferroalloys in 7202.
If remelted and cast into pipe fittings
Further worked into finished cast iron articles moves to Chapter 73.

Import Tips & Compliance
• Label shipments clearly as 'nonalloy pig iron >0.5% P' with supporting lab assays
• Ensure no cladding or coatings; Chapter 72 defines 'further worked' to prevent misclassification

High-Phosphorus Foundry Pig Iron
Pig iron cast in standard pig shapes with phosphorus content exceeding 0.5% by weight, primarily used in foundries for gray iron castings. It falls under HTS 7201.20.00.00 as nonalloy pig iron in primary forms with elevated phosphorus levels, distinguishing it from low-phosphorus variants. This composition enhances fluidity for complex castings like engine blocks.
Phosphoric Pig Iron for Ductile Iron Production
