The markets

Who says they write it

From each market's own appetite, product or program page (or a trade article quoting it), read on the date shown. Appetites change: the linked page controls. A market listed here isn't necessarily one this agency is appointed with; a licensed broker reaches most of them directly or through a wholesaler.

The UIIA page at intermodal.org/uiia/uiia-insurance-requirements publishes no approved-insurer roster; it only names Knights Specialty, Accredited Specialty, Trisura Specialty/Trisura Insurance and Progressive as insurers whose policies need coverage confirmation within 24 hours. Cover Whale's intermodal announcement (from search) resolved to its homepage with no intermodal text. National Interstate, Great West, Lancer and Prime pages do not name intermodal.

How Drayage and intermodal (UIIA) gets placed

Standard markets first where any will look at it; when they won't, the placement goes through surplus lines, where a licensed surplus lines broker places it with an eligible non-admitted insurer and files the state's surplus lines tax and stamping forms. In California, risks on the Department of Insurance export list can go to surplus lines without the usual diligent search of admitted carriers. Surplus lines policies aren't backed by a state guaranty fund, so the insurer's financial rating matters more.

What an underwriter will want before quoting: a full description of the operation, years in business and the owners' experience, revenue or payroll, loss runs (five years where available, currently valued), the contracts or venue requirements that set the limits, and photos or safety plans where the hazard is physical.
