bureau insurer

Insurer Operations — An insurance company that uses a rating bureau's rates and forms. Bureau insurers usually do not have a large enough data base or sufficient resources of their own to develop rates.

Nonbureau insurers
Insurance companies that do not start with the bureau rates in order to determine their own premium levels. They may refer to the bureau rates as a general guide, but will usually develop their own rates.
