I need some help identifying this insulation, I’m going to assume that it is cellulose but would like other opinions please?
Looks like it to me.

Thank you guys so much. So, when reporting on this type of insulation is there a disclaimer comment that should be added… incase I may make a mistake at any point in the future on identifying it?
There are only a few types of insulation commonly used today so you should be able to positively identify them. In the case of older homes with an unknown, non-typical insulation, or a mix of several types of insulation, I would just select “unknown insulation type” in your report software.

The cellulose insulation appears to be in dense packed balls or lumps. In the second images top left corner, the cellulose insulation was to the point of saturation and compacted into a hard dense blanket. Very little R-Value there.
I suspect poor attic circulation.
1: I would refer this to an insulation specialist for evaluation and posable removal. 2: New insulation. 3: Ventilation consultant.
Blown in cellulose insulation will last anywhere from 20 to 30 years, under ideal conditions. Those do not appear to be ideal conditions.
Just my 2 cents.

Depending on the manufacturer, you can sometimes find bits of news print to verify it is cellulose.

Cellulose is just shredded paper with a fire retardant on it, if you look close you can see different colors of paper and some newsprint. Rock wool is the other gray insulation I typically see, but it has a uniform consistency. You might try putting some down your shirt…cellulose doesn’t itch rock wool itches like hell…
