Subheading 360610 applies specifically to lighter fuel — typically butane or similar hydrocarbons — packaged in containers of 300 cm³ or less, the format used for consumer lighter refills. Larger bulk quantities of the same fuel are classified under the relevant petroleum or chemical heading based on their chemical composition, not here.

Complete disposable lighters are not classified here. Finished lighters with a flint or electronic ignition mechanism are classified in the heading covering lighters and smoking articles. This heading covers ferrocerium and pyrophoric alloys as materials or components, and lighter fuel in small retail containers — not the assembled lighter device.
