Propane is a factored product and is produced either as a by-product from the refinement of crude oil or through the extraction of natural gas from gas fields.

About the surcharge
Propane is a traded product and varies in price depending on market forces. A surcharge per cylinder is applied to propane cylinders to take into account changes to BOC's costs.
