This act applies to all classes and kinds of insurance which may be written by stock or mutual fire, marine or fire and marine insurance companies, associations or exchanges, on risks located in this Commonwealth. Inland marine insurance shall be deemed to include insurance now or hereafter defined by statute, or by interpretation thereof, or if not so defined or interpreted, by ruling of the Insurance Commissioner, hereinafter referred to as commissioner, or as established by general custom of the business as inland marine insurance.
This act shall not apply:
If any kind of insurance, subdivision or combination thereof, or type of coverage, subject to this act, is also subject to regulation by another rate regulatory act of this Commonwealth, an insurer to which both acts are otherwise applicable shall file with the commissioner, a designation as to which rate regulatory act shall be applicable to it with respect to such kind of insurance, subdivision or combination thereof, or type of coverage.
