I'm not sure if US has anything to do with this, but there's some EU regulation prohibiting use of fluoro in ski waxes. First it was for 2018 season already, but then they postponed it to 2020 or 21, not sure now. On top of that, Norway has their own stuff and all Swix stuff is non-fluoro since end of 2018 season. Since all (decent) ski wax companies are in Europe, I don't think US regulation matters as you simply won't get fluoro waxes produced anymore, even if they would be allowed in US.
Yeah I agree complete BS, as I'm sure that little fluoro that goes into ski waxes will really change world. Especially since there's so huge amount of ski waxes produced. I'm sure they could find better way to save planet then bother with so obscure thing as ski waxes. Every single pisten bully makes more damage to world and nature then all the fluoro in all ski waxes produces all over the world in whole year.... or decade.
And what's worse, even if Swix tells current non-fluoro HF waxes and overlays are just as good or even better then old fluoro ones, reality is different. All tests done show they suck compared to old fluoro waxes. But... you just can't have them anymore, unless you have some old stock, but sooner or later that will go.
