Agglomerated Coal Coke Briquettes
Agglomerated coal coke briquettes are formed by compressing coke fines or small coke particles into uniform briquettes, often for retail fuel applications such as barbecue grilling or home heating. The agglomeration process distinguishes these from bulk industrial coke products, and they fall under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
Blast Furnace Coke
Blast furnace coke is a premium coke with low volatile matter, produced from bituminous coal and essential for pig iron smelting. It meets strict coke strength (CSR) requirements and is agglomerated for structural integrity in blast furnace operations. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
Briquetted Coal Coke
Briquetted coal coke is fully coked coal that has been agglomerated into uniform briquettes for barbecue and industrial heating applications. It offers consistent burn with low smoke, making it a popular retail fuel product. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
Coal Semicoke Briquettes
Coal semicoke briquettes are agglomerated briquettes of low-temperature coal semicoke, used in heating and industrial boilers. Partial carbonization retains some volatiles, making them distinct from fully coked products. This product falls under tariff item 2704.00.00 as semi-coke of coal, whether or not agglomerated.
Cupola Furnace Coke (100-250 mm)
Cupola furnace coke is a premium blast furnace coke adapted for foundry cupolas, featuring pieces larger than 100 mm in diameter with superior shatter resistance. It provides high mechanical strength to maintain the burden in cupola melting operations. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
Ductile Iron Cupola Coke (100-200 mm)
Ductile iron cupola coke consists of strong metallurgical coke lumps over 100 mm in size, optimized for ductile iron foundries. It achieves at least 50% retention on a 100-mm sieve after ASTM D 3038 drop shatter testing, ensuring high mechanical strength. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
