Section 4: Restrictions on application
Section 4. This chapter shall apply to risks located in this commonwealth insured by insurance companies authorized to transact business in this commonwealth under the First, Second or Third clauses of section forty-seven of chapter one hundred and seventy-five, even though such risks are covered by policies or contracts of insurance issued pursuant to section twenty-two A of said chapter one hundred and seventy-five providing coverage under the aforementioned and any other clauses or subdivisions, other than subdivision (e) of the Sixth clause, of said section forty-seven of said chapter one hundred and seventy-five which, as part of the coverage thereof, insure real or personal property against loss or damage by fire at residential locations or which, as part of the coverage thereof, insure the output of a manufacturer against such loss or damage by fire at locations other than his manufacturing premises. Inland marine insurance shall be deemed to include insurance now or hereafter defined by law, or by interpretation thereof, or, if not so defined or interpreted, by ruling of the commissioner, or as established by general custom of the business, as inland marine insurance.
This chapter shall not apply?
(a) To reinsurance, other than joint reinsurance to the extent stated in section thirteen.
(b) To insurance of vessels or craft, their cargoes, marine builders' risks, marine protection and indemnity, or other risks commonly insured under marine, as distinguished from inland marine, insurance policies.
(c) To insurance of hulls of aircraft, including their accessories and equipment, or against liability arising out of the ownership, maintenance or use of aircraft.
(d) To motor vehicle insurance, nor to insurance against liability arising out of the ownership, maintenance or use of motor vehicles.
If any kind of insurance, subdivision or combination thereof, or type of coverage, subject to this chapter, is also subject to regulation by another rate regulatory law of this commonwealth, an insurer to which both laws are otherwise applicable shall file with the commissioner a designation as to which rate regulatory law shall be applicable to it with respect to such kind of insurance, subdivision or combination thereof, or type of coverage.
