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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ferrosilicon-manganese in granular or powder form
Ferroalloys not in pigs/blocks shift to heading 7202 specific subheadings.
If non-alloy pig iron in similar primary forms
Lack of characteristic spiegeleisen elements moves it to non-alloy pig iron.
If remelted and cast into pipe fittings
Finished cast iron articles are under Chapter 73, not primary forms.

Import Tips & Compliance
• Provide mill test certificates detailing Si and Mn percentages; avoid reclassification by proving no 'further worked' treatments per Chapter notes
• Use proper NAICS codes for steel foundry use to prevent end-use scrutiny

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.
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.
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.
