Washington Inland Marine Insurance, Separate from Ocean Marine Rating

Washington defines marine and transportation insurance to include cargo connected with transit, including preparation, delay, and storage, and it names bridges, tunnels, piers, dry docks, and dams and appurtenant waterway controls. The rating chapter does not apply to vessels, their cargoes, marine builders' risks, marine protection and indemnity, and other risks commonly insured under marine, as distinguished from inland marine, contracts. Inland marine that is written to manual or class rates still has a filing rule, except individually rated risks that by custom are not written to a manual.

What Is Inland Marine Insurance?

If your business moves equipment between sites or ships goods, inland marine can cover those property exposures; installation and other forms address different property categories. Match the quote to what you own, rent or hold for others. Read the national Tools, equipment and inland marine guide.

What Should You Watch for With Inland Marine Insurance in Washington?

Ocean Marine and Inland Marine Are Not the Same Rating Exemption
RCW 48.19.010(1)(e) removes insurance of vessels, their cargoes, marine builders' risks, marine protection and indemnity, and other risks commonly insured under marine, as distinguished from inland marine, insurance contracts, as the commissioner may define by ruling. An inland marine equipment floater does not get that vessel exemption. Ask which contract you are buying. ²
Manual Inland Marine Rates Are Filed
RCW 48.19.030(1) requires manual or class rates for the part of marine and transportation insurance that is not exempt under RCW 48.19.010, except specific rates on inland marine risks individually rated, which are not reasonably susceptible to manual rating and which by general custom are not written according to manual rates. A contractors' equipment class with a manual is not that exception. ³
Dams, Piers, and Bridges Are Named, With Building Exclusions
RCW 48.11.050(1)(d) includes bridges, tunnels, and other instrumentalities of transportation, excluding buildings, their furniture and furnishings, fixed contents, and supplies held in storage, plus piers, wharves, docks and slips, dry docks and marine railways, and dams and appurtenant facilities for the control of waterways. Ask whether a building or stored supplies on the project are outside that clause and need another form. ¹

Which Inland Marine Providers Have Washington License Records?

These providers publish a national listing for Tools, equipment and inland marine; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Washington. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁵
