Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If manganese content below spiegeleisen thresholds
Lower alloy pig iron classified as non-spiegeleisen under same heading.
If sold in crushed lump form for direct addition
Processed ferromanganese enters as ferroalloy, not primary pig iron.
If cast into finished grill/basket shapes
Articles of iron become Chapter 73 products regardless of material.

Import Tips & Compliance
• Include end-use statement for foundry applications to avoid industrial vs retail confusion
• Test for 'further worked' coatings/phosphatizing which disqualifies from 7201

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.
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.
