Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If reduced to breeze size <32 mm
Size threshold determines breeze vs. nut coke subheading.
If imported as steam coal before coking
Bituminous coals for energy use classified under 2701.19 prior to processing.
If shaped into refractory bricks
Agglomerated into articles for furnaces moves to Chapter 69.

Import Tips & Compliance
• Specify particle size distribution in commercial invoice to differentiate from lump or breeze
• Comply with EPA clean air regs; provide emission factor data if applicable

Metallurgical Coke Lump
Lump metallurgical coke produced from coking coal, used primarily in blast furnaces for iron production. It falls under HTS 2704.00.00.25 as coke and semicoke of coal, other than specific types like coke breeze. Agglomerated form enhances its strength for high-temperature applications.
Foundry Coke
High-quality foundry coke from metallurgical coal, agglomerated into large pieces for cupola furnaces in metal casting. Classified under 2704.00.00.25 as other coke and semicoke of coal due to its specific use and size. Provides consistent heat and low ash content.
Blast Furnace Coke
Premium blast furnace coke, low volatile matter from bituminous coal, essential for pig iron smelting. Under HTS 2704.00.00.25 as other coal coke, agglomerated for structural integrity. Meets strict CSR (coke strength) standards.
Coal Semicoke Briquettes
Agglomerated briquettes of low-temperature coal semicoke, used in heating and industrial boilers. Classified in 2704.00.00.25 as semicoke of coal, other. Partial carbonization retains some volatiles.
Coke Breeze Fines
Recycled fines from metallurgical coke crushing, under 32 mm but specified as other for certain blends. HTS 2704.00.00.25 for non-standard other coke. Used in sinter plants and power generation.
Lump Semicoke of Coal
Low-temperature carbonized coal in lump form, for non-blast furnace uses like cement kilns. Under 2704.00.00.25 as other semicoke of coal. Higher volatiles than metallurgical coke.
