Metallurgical Coke
Metallurgical coke is a high-carbon fuel produced by heating coking coal in the absence of air, used primarily in blast furnaces for iron production. It falls under HTS 2704.00.00.50 as coke of coal, not agglomerated, and classified as 'other' since it is not specified elsewhere in the heading.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not fully coked and retains bituminous properties
Partially processed bituminous coal with >14% volatile matter is classified under raw coal headings, not coke.
If specifically identified as petroleum coke
Petroleum coke from oil refining falls under a separate provision in 2704, distinguished by source material.
If chemically treated for non-fuel industrial use
Processed coke residues prepared as chemical products shift to Chapter 38 for prepared binders or additives.

Import Tips & Compliance
• Verify volatile matter content via lab testing to confirm classification as coke, not raw coal under 2701
• Obtain certificates of analysis proving it's retort carbon or coal coke to avoid misclassification as petroleum coke (2704.00.10)
• Ensure bulk packaging documentation specifies non-agglomerated form to prevent shifts to agglomerated subheadings

Foundry Coke
Foundry coke is a porous, low-ash coke derived from coal, ideal for cupola furnaces in metal casting operations. Classified under HTS 2704.00.00.50 as 'other' coal coke, whether or not agglomerated, due to its production process and fuel application.
Lignite Coke
Lignite coke, or brown coal coke, is produced by carbonizing lignite, used as a low-cost fuel in power generation and industrial heating. It is covered by HTS 2704.00.00.50 as coke or semicoke of lignite, in the 'other' category.
