High-Phosphorus Foundry Pig Iron from China
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.

Import Tips
• Obtain chemical analysis certificates verifying phosphorus >0.5% and nonalloy status to avoid reclassification to 7201.10
• Ensure pigs are in primary forms without further working like machining, per Chapter 72 notes
• Declare exact weight and composition; common pitfall is rust discoloration affecting duty allowances
