The bottle I have in front of me does say 'Jaso FB' API TC/TC+ ratings, but it does say on the front "Fully synthetic engine oil for chain saws and power tools" "Biodegradable" and "Contains fuel stabilizers".
Amazing. API-TC hasn't tested anything since 1995 and there is no such rating as TC+
You will also notice that although Stihl talks about JASO ratings, there is no certification label or registration number, so it looks like they are maybe decorating the label with some bogus ratings.
Husky on the other hand tells no such fibs. They show no ratings of any kind; so they're essentially saying "trust us".
The real truth, as I have the entire JASO list in front of me, is that both Husky and Stihl are apparently too cheap to send a drum of oil and a check for $3700 to Japan and have it tested/certified. That's why I use the Red Max oil in my stuff. It has an FD rating, which is the newest and highest rating that JASO has. The main difference between FC and FD is the increased tolerance of ethanol blended fuels.
