Heading 7201

Pig iron and spiegeleisen in pigs, blocks or other primary forms

4 declarable lines

Heading 7201 covers pig iron and spiegeleisen in pigs, blocks or other primary forms, meaning the crude iron product that comes straight from a blast furnace before any further refining or shaping. The heading splits first into nonalloy pig iron, which is divided by phosphorus content at the 0.5% by weight line, and a residual group for alloy pig iron and spiegeleisen. All four declarable lines in this heading carry a general (MFN) duty rate of Free.

Products in this heading

Pig iron in pigs (crude cast iron blocks) from a blast furnace
Nonalloy pig iron with 0.4% phosphorus used as steelmaking feed
High phosphorus nonalloy pig iron with 0.8% phosphorus
Alloy pig iron blocks containing alloying elements
Spiegeleisen in pigs or blocks
Crude iron poured into block or other primary form for remelting

How to choose the right subheading

Phosphorus content by weight: 0.5% or less goes to 7201.10, more than 0.5% goes to 7201.20.
Whether the pig iron is nonalloy or alloy: alloy pig iron is classified in 7201.50.
Whether the product is spiegeleisen rather than alloy pig iron: spiegeleisen has its own line, 7201.50.60.
Whether the goods are in a primary form such as pigs, blocks or similar crude shapes rather than granules, powder or finished articles.
Confirm the goods are furnace pig iron and not refined iron ingots or directly reduced iron.

Often confused with

Ferroalloys such as ferromanganese or ferrosilicon
Ferroalloys are a separate heading, even when sold in lump or block form.
Heading 7202
Directly reduced iron or sponge iron pellets
Iron obtained by direct reduction is not furnace pig iron and is named in 7203.
Heading 7203
Iron or steel scrap and remelting scrap ingots
Scrap and remelting ingots are covered by the waste and scrap heading.
Heading 7204
Granules and powders of pig iron
Once the pig iron is reduced to granules or powder it leaves 7201.
Heading 7205
Iron ingots cast from refined molten iron rather than furnace pig
Ingots of iron and nonalloy steel in primary forms are classified in 7206.

Frequently asked questions

What is the HTS code for nonalloy pig iron with 0.5% or less phosphorus?

That product is classified under 7201.10.00.00, which carries a general (MFN) duty rate of Free.

What is the duty on spiegeleisen in pigs or blocks?

Spiegeleisen is classified under 7201.50.60.00 and its general (MFN) duty rate is Free.

How do I classify alloy pig iron?

Alloy pig iron falls under 7201.50.30.00, with a general (MFN) duty rate of Free. Phosphorus thresholds only split the nonalloy lines, 7201.10.00.00 and 7201.20.00.00.
