Hi! While salsa is a very popular partner dance, it is not considered once of the 19 competitive dance sport categories. I'm basing this off of the ISTD syllabus, so feel free to check me!
At least in the USA, salsa often included in ballroom competitions social dance category along with hustle, bachata, and various forms of swing, so people sometimes lump it in as "ballroom dance" colloquially too!
