Products classified under HTS 2705.00.00.00
Coal Gas
Coal gas is a flammable gaseous fuel produced by the destructive distillation of coal, primarily consisting of hydrogen, methane, and carbon monoxide. It falls under HTS 2705.00.00.00 as it is explicitly listed as a coal gas, distinct from petroleum gases or other gaseous hydrocarbons.
Water Gas
Water gas is produced by passing steam over incandescent coke or coal, yielding a mixture of hydrogen and carbon monoxide used as an industrial fuel. Classified under HTS 2705.00.00.00 as 'water gas', explicitly excluding petroleum-based gaseous hydrocarbons.
Producer Gas
Producer gas, generated by partial combustion of coal or biomass with air, contains carbon monoxide, hydrogen, and nitrogen, used mainly in industrial heating. It is covered by HTS 2705.00.00.00 as a 'similar gas' to coal gas, specifically excluding petroleum hydrocarbons.
Blast Furnace Gas
Blast furnace gas is a byproduct from iron smelting, composed of nitrogen, carbon monoxide, carbon dioxide, and hydrogen, used as fuel in steel mills. It qualifies under HTS 2705.00.00.00 as a similar gas produced from coal/coke processes, not petroleum-derived.
Town Gas
Town gas is a historical coal-derived fuel gas mixture of hydrogen, methane, and CO, once distributed for lighting and heating. Under HTS 2705.00.00.00, it is included as coal gas or similar, differentiated from modern natural gas imports.
Blue Gas (Water Gas Variant)
Blue gas is a high-purity water gas variant with minimal CO2, produced by steam-carbon reactions for industrial applications. Classified in HTS 2705.00.00.00 as water gas, explicitly other than petroleum gaseous hydrocarbons.
Semi-Water Gas
Semi-water gas is a mixture produced by air and steam over hot coke, balancing producer and water gas properties for fuel use. It fits HTS 2705.00.00.00 as a similar gas from coal processes, not hydrocarbon petroleum gases.
