This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
2704.00.00Briquetted 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.
2704.00.00Coal 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.
2704.00.00Cupola 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.
2704.00.00Ductile 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.
2704.00.00Foundry Coke
Foundry coke is a large-lump coke produced from low-ash bituminous coal, specifically designed for use in cupola furnaces to melt metals such as cast iron. Its high mechanical strength and low reactivity make it suitable for supporting the burden in foundry operations. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
2704.00.00Foundry Grade Metallurgical Coke (150-200 mm)
Foundry grade metallurgical coke is produced from coking coal with a maximum diameter exceeding 100 mm and at least 50% retained on a 100-mm sieve after ASTM D 3038 drop shatter testing. It is specifically designed for foundry cupola operations, providing carbon and heat for iron melting. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
2704.00.00Gas Works Coke
Gas works coke is a byproduct of coal gasification, produced when coal is heated in gas retorts to generate town gas. It is typically dusty and contains impurities, making it suitable for industrial fuel or soil amendment applications. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
2704.00.00Gray Iron Foundry Lump Coke (120-300 mm)
Gray iron foundry lump coke is sized between 120-300 mm and passes ASTM D 3038 testing with at least 50% retention on a 100-mm sieve after drop shatter. It is essential for cupola operations, providing carbon and heat in iron melting processes. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
2704.00.00Lignite Coke
Lignite coke is produced by carbonizing lignite, also known as brown coal, through a high-temperature process. It is often used in power generation or as a low-cost fuel reductant in industrial applications. This product falls under tariff item 2704.00.00 as coke or semi-coke of lignite, whether or not agglomerated.
2704.00.00Metallurgical Coal Coke
Metallurgical coal coke is a 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. Its high carbon content and low impurities make it essential for metallurgical processes. This product falls under tariff item 2704.00.00 as coke of coal, whether or not agglomerated.
2704.00.00Peat Coke (Semicoke)
Peat coke, also known as semicoke, is derived from the low-temperature carbonization of peat, resulting in a product used for heating or gasification processes. It can be supplied in agglomerated briquettes or loose form. This product falls under tariff item 2704.00.00 as coke or semi-coke of peat, whether or not agglomerated.
