Metallurgical Coal Coke
High-quality coke produced by carbonizing bituminous coal in coke ovens, used primarily as a fuel and reducing agent in blast furnaces for iron production. It falls under HTS 2704.00.00 as coke of coal, typically agglomerated into uniform lumps. This product meets the chapter's definition for coal-derived coke used in industrial metallurgy.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unprocessed bituminous coal feedstock
Raw bituminous coal before coking process falls under Chapter 27 heading 2701 for coal, not the derived coke in 2704.
If further processed into pig iron
Coke used to produce pig iron changes classification to Chapter 72 iron and steel products.
If chemically treated for non-fuel use
Impregnated or chemically modified coke for specialized applications moves to prepared binders or chemical preparations.

Import Tips & Compliance
• Verify coke quality certificates confirming volatile matter and ash content to meet U.S. steel industry standards; ensure proper documentation for bulk shipments to avoid demurrage; declare exact origin as coal, lignite, or peat to prevent misclassification

Foundry Coke
Large-lump coke from low-ash bituminous coal, designed for cupola furnaces in foundries to melt metals like cast iron. Classified under HTS 2704.00.00 as coke of coal, agglomerated for high strength and low reactivity. Ideal for non-ferrous and ferrous foundry operations.
Lignite Coke
Coke obtained from carbonizing lignite (brown coal), often used in power generation or as a low-cost fuel reductant. It qualifies for HTS 2704.00.00 as coke or semicoke of lignite, whether agglomerated or fines. Lower calorific value than coal coke but abundant source.
Peat Coke (Semicoke)
Semicoke derived from low-temperature carbonization of peat, used in heating or gasification processes. Covered by HTS 2704.00.00 as coke or semicoke of peat, in agglomerated briquettes or loose form. Environmentally sourced from renewable peat bogs.
Retort Carbon
High-purity carbon produced in retorts from coal or other sources, used in electrode manufacturing or chemical processes. Specifically named in HTS 2704.00.00 as retort carbon, typically in powdered or granular form. Differs from standard coke by production method.
Agglomerated Coal Coke Briquettes
Coal coke formed into uniform briquettes for retail fuel sales, such as in BBQ or home heating. Falls under HTS 2704.00.00 as agglomerated coke of coal. Convenient packaging distinguishes from bulk industrial coke.
Petcoke (Petroleum Coke Fines)
Note: While primarily from petroleum, certain coal-blend petcoke fines resembling coal coke are classified here; used in cement kilns. HTS 2704.00.00 covers borderline coal-derived semicokes. High sulfur content requires careful handling.
