Where it sits on the label

Washing
Bleaching
Drying
Ironing
Professional care

Washing comes first of the five. A label is always written in this order and simply leaves out whatever does not apply, so a tag carrying only three symbols is not missing anything. The next shape along yours is the next of these its maker had something to say about.
