High-Manganese Spiegeleisen Pig from China

Spiegeleisen in pig form containing high levels of manganese and silicon, used primarily as a ferroalloy additive in steel production to enhance deoxidation and desulfurization. It falls under HTS 7201.50.60.00 as spiegeleisen, a specific type of high-manganese, high-silicon pig iron designed for alloying purposes in primary form. This classification distinguishes it from standard pig iron due to its specialized composition.

Import Tips

Verify chemical composition certification showing manganese >5% and silicon >20% to confirm spiegeleisen classification per Chapter 72 notes

Ensure documentation includes foundry analysis reports; common pitfall is misclassification as basic pig iron under 7201.10

Declare in primary pig form only; further worked products shift to other headings
