14.3 Inland Marine and Nationwide Marine Definition

Key Takeaways

  • Inland marine covers property in transit, movable property, bailee interests, and instrumentalities of transportation/communication - usually open-perils and nationwide.
  • The NAIC Nationwide Marine Definition (a regulatory document, not a form) lists eligible marine classes and bars fixed-location property from marine forms.
  • Filed forms are standardized; non-filed forms are insurer-judgment for unusual risks; common forms include contractors equipment, motor truck cargo, and bailee floaters.
  • Scheduling high-value items on a Personal Articles Floater provides open-perils, worldwide, often no-deductible coverage that overrides homeowners special limits.

Inland Marine Insurance

Inland marine insurance evolved from ocean marine to cover property in transit over land, movable property, and property that is the subject of a bailment, plus certain instrumentalities of transportation and communication (bridges, tunnels, pipelines, radio/TV towers). It is largely open-perils and nationwide in scope, making it ideal for property that moves or has no fixed location.

The scope of what may be written as inland marine is governed by the Nationwide Marine Definition, adopted by the National Association of Insurance Commissioners (NAIC). This regulatory document - not a coverage form - lists the classes of property eligible for marine (ocean and inland) insurance and prevents insurers from writing ordinary fixed-location property as marine.

The Nationwide Marine Definition - Eligible Classes

The Nationwide Marine Definition broadly authorizes inland marine on six families of property:

  1. Imports and exports (ocean/foreign trade transit)
  2. Domestic shipments (goods in transit by rail, truck, air, mail)
  3. Instrumentalities of transportation and communication (bridges, tunnels, piers, pipelines, power transmission lines, towers)
  4. Personal property floaters (movable personal property - jewelry, furs, fine arts)
  5. Commercial property floaters (movable business property)
  6. Certain instrumentalities and bailee interests

It also restricts marine writing: property at a permanent location (a building, furniture in a fixed office) is not eligible as inland marine - that belongs in property/BOP/CPP forms.

Common Inland Marine Forms

Filed (controlled) forms are standardized by ISO/AAIS; non-filed (uncontrolled) forms are written by insurer judgment for unusual exposures. Frequently tested forms:

Form / FloaterInsures
Commercial Articles Coverage FormCameras, musical instruments (commercial)
Contractors Equipment FloaterMobile tools, equipment off-site
Equipment Dealers Coverage FormDealer stock of mobile equipment
Motor Truck CargoCarrier's liability for others' goods in transit
Transportation/Annual TransitShipper's own goods in transit
Accounts Receivable / Valuable PapersRecords and documents
Bailee's Customers (e.g., dry cleaners)Customers' property in insured's care
Jewelers Block / FurriersDealer stock and customer goods

Personal Inland Marine - The PAP and Scheduled Floaters

On the personal side, the Personal Articles Floater (PAF) and the homeowners Scheduled Personal Property endorsement (HO 04 61) schedule high-value items (jewelry, furs, fine arts, silverware, cameras, golf equipment, stamps/coins). These provide:

  • Open-perils, worldwide coverage (broader than homeowners special-limits)
  • Agreed value for fine arts (no depreciation dispute)
  • No deductible on most scheduled items

Worked example: A homeowners policy caps theft of jewelry at a $1,500 special limit. A $9,000 engagement ring is stolen. Unscheduled, the owner recovers only $1,500. If the ring were scheduled on a PAF for $9,000, the recovery is the full $9,000 with no deductible - illustrating exactly why scheduling matters.

How Inland Marine Pricing and Forms Work

Beyond the eligible classes, the exam tests how inland marine forms are filed and rated. Filed (controlled) forms are standardized and rate-filed with the state (commercial articles, contractors equipment, signs); non-filed (uncontrolled) forms are written by underwriter judgment for unusual exposures (a touring exhibit, a specialized one-of-a-kind risk) and are not subject to standard filings.

ConceptDetail
ValuationOften agreed/stated value for fine arts and unique items
PerilsUsually open-peril, broader than property forms
TerritoryTypically nationwide / worldwide, ideal for movable property
CoinsuranceMany floaters have no coinsurance

Bailee Coverage

A bailee holds others' property for a purpose (dry cleaner, repair shop, warehouse). Bailee's Customers floaters cover customers' property in the insured's care, custody, or control - a gap the CGL specifically excludes (care-custody-control exclusion). This is why a repair shop needs inland marine, not just a CGL.

Worked Example

A jeweler operates a repair counter holding customers' watches. A fire destroys $40,000 of customer property being repaired. The jeweler's CGL excludes property in its care, custody, or control, and its property policy covers only owned stock - so neither responds to the customers' items. A Jewelers Block / Bailee floater (inland marine) covers the $40,000 of customers' property. Recognizing that customer/bailment property needs inland marine because the CGL's care-custody-control exclusion removes it is the central tested gap.

Contractors face the parallel need: a Contractors Equipment Floater covers mobile tools off-site that the commercial property form (fixed-location) does not.

Documentation, Symbols, and Transit Coverage

Inland marine transit coverage protects goods moving by truck, rail, air, or mail, distinguishing the shipper's interest (Transportation/Annual Transit floater for the shipper's own goods) from the carrier's legal liability (Motor Truck Cargo for a trucker hauling others' goods). Because inland marine is largely open-peril, nationwide, and often no-coinsurance, it is the form of choice for mobile, in-transit, and bailment property that fixed-location property forms cannot reach.

The exam also distinguishes scheduled floaters (each item listed with its own value) from blanket floaters (one limit over a class of property). Personal scheduled floaters such as the Personal Articles Floater provide agreed-value, worldwide, open-peril, no-deductible coverage that overrides the homeowners special limits - the recurring reason to schedule jewelry, furs, and fine arts. Bailee coverage closes the CGL's care-custody-control gap, paying for customers' property in the insured's possession even though the CGL would deny it.
