im not sure about liberty and 4frnt. ive always heard that they were made in the US but i couldn't find any proof of it.
Jskis doesn't have a factory. They are made by Utopie in QC.
Liberty is made in China.
Most of the skis 4frnt build are made in Europe. They do a small number of WhiteRoom skis in house in SLC.

I know Bluehouse was starting to bring production in house (with one model the first year they came over, while still making skis in China. I'm not sure at this point if they are still outsourcing some of their production or not.
Praxis building everything in house.
RMU (I believe) is currently split between Never Summer in Denver with some skis going to Utopie in QC, but I could be wrong there.
Most of the major brands have their own factories (Atomic, Elan, Salomon, etc).
As for non-majors making skis in their own factory (just off the top of my head, definitely going to miss a bunch)....

This doesn't include a ton of other small brands with their own factories from both Europe & N. America - Foon, Slant, Zai, Romp, Volition, Bumtribe, Caravan, Community, Big Wood, Crown, Deviation, Ellison, Fortitude, Gary Wayne, Seneca, Blossom, Skevik, Extrem, Viice, WSD.....and a bunch of others I am forgetting.
So many brands now. There seems to be at least several new brands popping up each month. It is pretty hard to keep up with all the new brands these days.
