14.3 Inland Marine and Nationwide Marine Definition

Inland Marine Insurance

Inland marine grew out of ocean marine: it covers property in transit over land and movable/mobile property that the standard fire/property policy handles poorly. Coverage is broad, often all-risk (open peril), and frequently written on a floater that follows the property wherever it goes. The scope of what qualifies as inland marine is governed by the Nationwide Marine Definition.

The Nationwide Marine Definition

First adopted in 1933 and revised in 1953 and 1976, the Nationwide Marine Definition is a model that states what insurers may write as marine (ocean and inland marine). It enumerates eligible classes so that inland marine is not used to circumvent rate regulation of standard property lines. The six broad categories of eligible inland marine property are:

1. Imports
2. Exports
3. Domestic shipments
4. Means of transportation and communication (bridges, tunnels, pipelines, radio/TV towers, etc.)
5. Personal property floater risks
6. Commercial property floater risks

Filed vs. non-filed (controlled vs. uncontrolled) classes

Inland marine splits into two regulatory groups:

• Filed (controlled) classes - standardized ISO forms with filed rates/forms. Examples: Accounts Receivable, Valuable Papers and Records, Signs, Camera/Musical Instrument floaters, Equipment (Contractors) floater, Commercial Articles, Physicians and Surgeons Equipment.
• Non-filed (uncontrolled) classes - forms and rates set by the insurer (e.g., Jewelers Block, Furriers, large transit/bailee risks). These give underwriters flexibility for unusual exposures.

Key floaters and bailee forms

• Transportation floaters - cover the insured's own goods in transit (e.g., Annual Transit, Trip Transit).
• Motor Truck Cargo - legal-liability or owner's-goods coverage for trucked freight.
• Bailee forms - cover customers' property in the insured's care (e.g., Bailees Customers, dry cleaners). A bailee is responsible for property of others only to the extent of its legal liability, but bailee forms often pay regardless of fault to preserve goodwill.
• Equipment floaters - the Contractors Equipment Floater covers mobile tools/machinery on a scheduled or blanket basis.

Common conditions and valuation

Many inland marine floaters use valued or agreed-value settlement for unique items (fine art, jewelry) rather than ACV. Standard conditions include a pair-and-set clause (loss to one item of a set is not paid as a total loss of the set) and a labels clause for damaged stock. The Coverage Territory for many floaters is the U.S. and Canada, distinguishing inland marine from ocean marine's worldwide scope.

Worked example - agreed value floater

A gallery insures a sculpture on a fine arts floater with an agreed value of $40,000 (no coinsurance). The piece is destroyed. On a valued floater, the insurer pays the agreed $40,000, with no need to prove ACV or replacement cost. Contrast this with an ACV settlement: if a 5-year-old projector listing at $4,000 new depreciates 50%, an ACV floater would pay $2,000, not $4,000. Knowing which floaters are agreed-value vs. ACV is a frequent test point.

Filed vs. Non-Filed Classes

Inland marine splits into two regulatory groups the exam tests directly. Filed (controlled) classes use standardized ISO forms and filed rates - accounts receivable, valuable papers, signs, camera and musical-instrument floaters, the contractors equipment floater, and physicians and surgeons equipment. Non-filed (uncontrolled) classes let the insurer set forms and rates for unusual exposures such as jewelers block, furriers, and large transit or bailee risks. When a stem asks why a particular floater can be tailored freely, the answer is that it falls in the non-filed group.

Floaters, Bailees, and Territory

The Nationwide Marine Definition keeps inland marine from poaching standard property lines by enumerating eligible classes - imports, exports, domestic shipments, instrumentalities of transportation and communication, and personal and commercial floater risks. Transportation floaters cover the insured's own goods in transit, motor truck cargo covers trucked freight, and bailee forms cover customers' property in the insured's care, often paying regardless of fault to preserve goodwill. -and-Canada territory and frequently settle unique items on an agreed-value basis rather than ACV.

Agreed Value vs. ACV Floaters

A frequent test point is which floaters settle on agreed value and which on actual cash value. Unique, hard-to-value items such as fine art and jewelry typically use a valued or agreed-value basis that pays the scheduled amount with no coinsurance and no need to prove depreciation, while ordinary equipment floaters settle on ACV, deducting depreciation. A gallery's $40,000 agreed-value sculpture pays $40,000 if destroyed, whereas a five-year-old projector listing at $4,000 new and depreciated 50% pays only $2,000 on an ACV floater.

Standard Floater Conditions

Inland marine floaters carry conditions worth recognizing. The pair-and-set clause treats loss to one item of a set as a partial loss rather than a total loss of the set, the labels clause addresses stock whose labels are damaged, and many floaters extend coverage on a broad open-peril basis because the property is mobile and exposed to varied risks in transit. These conditions, plus the U.S.-and-Canada territory, distinguish inland marine from both standard property and worldwide ocean marine.

Origins and the Regulatory Purpose

Inland marine grew out of ocean marine to cover property in transit over land and movable property the standard fire policy handled poorly, and the Nationwide Marine Definition exists to keep that flexibility from undercutting rate regulation of standard property lines. Recognizing that an exposure - goods in transit, a contractor's mobile equipment, a customer's property held as bailee - belongs in inland marine rather than commercial property is the foundational skill the exam tests on this line.
