What is Inland Marine Insurance?

Inland marine covers property in transit and specialty mobile property: contractors equipment, builders risk, motor truck cargo, fine arts, and jewelers block. Carriers, MGAs, and TPAs need a platform that handles scheduled and blanket floaters.

Inland Marine P&C Knowledgebase For carriers, MGAs, and TPAs

Inland marine insurance is the family of P&C lines that covers property in transit and specialty mobile property — contractors equipment, builders risk, motor truck cargo, fine arts, jewelers block, scheduled personal property (jewelry, furs, cameras, musical instruments), and miscellaneous bailee floaters.

This page is a line-of-business reference for inland marine carriers, MGAs, TPAs, and program administrators evaluating a policy administration platform for scheduled and blanket inland-marine floaters.

Mechanics

In-Transit and Mobile Property

Inland marine grew out of ocean-marine forms covering goods in transit on inland waterways and now covers a wide range of property that moves or whose value isn't tied to one location: contractors equipment, motor truck cargo, fine arts on loan, scheduled personal property.

The platform has to support scheduled items (per-item value, description, serial number) and blanket coverage (single limit on a class) on the same policy.

Builders Risk

Course-of-Construction

Builders risk is an inland-marine product covering buildings under construction on a course-of-construction basis. Limits step up as construction progresses; coverage usually ends at completion or occupancy.

Mercury supports configurable builders-risk products with completed-value or reporting-form rating, occupancy triggers, and date-driven endorsement applicability through the policy lifecycle.

Cargo

Motor Truck Cargo

Motor truck cargo is the inland-marine product carriers write to cover a trucker's legal liability for cargo while in their care, custody, or control. Rated on revenue, fleet size, commodity, and radius of operation.

Mercury's configurable rating supports revenue-based, per-power-unit, and class-coded MTC rating, with carrier-of-record schedules and additional-insured certificate workflows.

Floaters

Scheduled and Blanket Floaters

Scheduled personal property floaters cover named personal articles — jewelry, furs, cameras, fine arts, musical instruments — at agreed value or actual cash value. Blanket floaters cover a class up to a single limit.

Mercury supports configurable schedules with itemized values, blanket sublimits, and rating tables driven by class, location, and protective-safeguards endorsements.
