Where is your butane made? And why it matters
Two cans or cylinders can carry the same label and very different contents. Where butane is refined, how it is filled and what it is stored in all decide what comes out of the valve. Here is what to ask.

Refining is only the first step
Butane can be refined to a high purity and still pick up contaminants afterward. Every transfer line, storage tank, can and valve it touches is a chance to add oil, moisture or particles. A supplier's purity claim only means something if the filling and packaging are just as clean.
The can and valve problem
Cans and valves are made on machinery that uses lubricants. If that residue is not removed, it can end up in the product, no matter how many times the butane was filtered upstream. That is one reason residue and non-volatile content are worth checking on a Certificate of Analysis.
Supply chain and lead time
Butane that crosses an ocean can sit in port and in warehouses before it reaches you, and you often cannot trace which lot you received. A supplier that fills close to you can ship faster, keep lots traceable and resupply on a schedule.
Where Puretane is filled
Puretane is filled in North America, with locations in Yahk, British Columbia and Hayden, Idaho. Our n-butane is triple refined and filtered 11 times, and lab-tested at 99.68% n-butane with sulfur, moisture and BTEX below detection. We produce 5,000 cylinders a month and ship pallets across the US and Canada in 2 to 8 days. More about Puretane.
