Low-Phosphorus Foundry Pig Iron from China
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.

Import Tips
• 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
