So, I’ve been noticing over the last several years, that all gas canister production appears to be moving to Korea (except Coleman). Those brands that were produced elsewhere are now produced in Korea. The following brands appear to all be made by the same manufacturer: Optimus, Primus, MSR, Snow Peak, and Jetboil.
All the caps are the same on the various brands:
Snow Peak was the last hold out (except Coleman). They’re now produced in Korea, and their cap is the same as the rest.

For Optimus, Primus, MSR, Snow Peak, and Jetboil:
All the canister weights (empty) are about the same, within a couple of grams or so.
The shape of the canisters is all the same.
The dimensions are all the same.
The caps are all the same (except for color).
The manufacturing process leaves the same raised area below the lip of the canister.
I was curious to know who this single manufacturer is who appears to be producing all the canisters for all the major brands.
I did a bit of digging. I found this blurb about Taeyang Industrial Co. Ltd. of Korea:
Taeyang Ind. is the largest portable butane gas cartridge maker in the world, dominating around 70% of global market share as well as 80% of domestic market share as of 2009. Equipped with advanced facilities covering everything from cartridge printing and coating to gas charging, the company exported its butane gas and cartridge more than 50 countries under the brand name ‘SUN’.
KoreaÂ’s domestically produced portable butane gas cartridge, now the worldÂ’s best, can be used for portable gas stoves and torches. Customized to our clientsÂ’ needs, we produce the best quality products and export it to about 50 countries worldwide, including Japan, the United States, Europe and Southeast Asia. Â [emphasis added]
Sounds like we have our prime suspect as to who it is that produces canisters for all the major brands (except Coleman).
If all the major canister brands (well, at least in the US where I live) are produced by a single manufacturer, what might the implications of that be for canister stove users?
