Liquefied Butane Fuel Mixture 92% Purity
This is a liquefied petroleum gas (LPG) mixture primarily consisting of butanes at 92% liquid volume purity, with minor propane and other hydrocarbon impurities. It falls under HTS 2711.13.00.10 due to its butane content being 90% or more but less than 95% by liquid volume, distinguishing it from higher purity butanes. Commonly used as an industrial fuel or refrigerant blend.
92% Butane LPG for Industrial Burners
