Liquefied Butane Fuel Mixture 92% Purity from China

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.

Import Tips

Verify purity via ISO 3405 distillation test to confirm 90-95% butane content for correct classification

Include safety data sheets (SDS) and material safety certificates; ensure DOT-compliant cylinders for transport

Avoid misclassification as propane-rich mixes; common pitfall is purity threshold errors leading to audits
