High-Manganese Spiegeleisen Pig
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing >2% by weight of carbon and presented in lumps
Ferromanganese lumps used in steelmaking fall under ferroalloys of heading 7202, not primary pig iron forms.
If low alloy content without high manganese/silicon
Non-alloy pig iron in pigs or blocks is classified separately from spiegeleisen.
If classified as other slag/ash containing recoverable metals
Ferrous by-products not meeting pure spiegeleisen specs may go to Chapter 26.

Import Tips & Compliance
• 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

Standard Spiegeleisen Sows
Large sow-shaped castings of spiegeleisen, a high-silicon, high-manganese pig iron used in foundries for gray iron production. HTS 7201.50.60.00 applies to this primary form spiegeleisen, distinct from other alloy pig irons by its specific mirror-like fracture and composition. Essential for introducing alloying elements during melting.
Mirror Spiegeleisen Blocks
Spiegeleisen blocks exhibiting the characteristic silvery mirror fracture, high in silicon for steel deoxidizer applications. Falls squarely under HTS 7201.50.60.00 for spiegeleisen in primary block form without further working as per Chapter 72 notes. Used in electric arc furnaces for alloy adjustment.
Silico-Manganese Spiegeleisen Block
Spiegeleisen cast into blocks with elevated silicon and manganese content, serving as a nodulizing agent in cast iron production. Classified under HTS 7201.50.60.00 for its primary form and spiegeleisen composition as defined in Chapter 72. It provides essential alloying elements without further working.
Foundry-Grade Spiegeleisen Pigs
Spiegeleisen pigs optimized for foundry use, with controlled manganese and silicon for consistent nodulization in ductile iron. This primary form product is specifically HTS 7201.50.60.00 as spiegeleisen, per US note definitions excluding further surface treatments. Critical for high-quality castings in automotive parts.
