Carriers we cover for inland marine insurance

Approximately 5.7 million U.S. small businesses operate as construction, contracting, or trades enterprises with significant tools and mobile equipment exposure — and the standard commercial property policies most of them carry do not fully cover that exposure once it leaves the business premises.¹ Inland marine insurance fills that gap.

Despite the name, inland marine has nothing to do with boats. The term is a 19th-century artifact from when ocean marine policies were extended to cover goods continuing inland by rail or truck. Today, inland marine refers to a broad category of coverage for property that moves, is in transit, or sits temporarily at locations the primary commercial property policy does not reach. For contractors, mobile service businesses, jewelers, photographers, and any business with significant off-premises property exposure, inland marine is often the difference between a single bad day and a business-ending loss.

This page covers what inland marine actually covers, the seven most common policy types, who needs it, what it costs, and how it interacts with general liability and commercial property. Every claim is tied to a published source.

What inland marine insurance covers

Inland marine policies cover business property in five general scenarios:²

Property in transit. Tools, equipment, inventory, and goods being transported between business locations or to/from job sites — whether by company vehicle, common carrier, or third-party shipper.
Property at temporary locations. Items at job sites, trade show booths, client locations, and other places not listed as a permanent business premises on a commercial property policy.
Mobile equipment. Tools, machinery, and equipment that move with the business — contractor tools, mobile diagnostic equipment, photographer cameras and lenses, mobile food trucks' equipment.
Property of others in your care. Goods held for storage, repair, processing, or sale that belong to customers or third parties (the "bailee" exposure for repair shops, dry cleaners, jewelers).
Specialized property categories. Computers, medical equipment, fine art, valuable papers, accounts receivable records, and other property categories with specialized coverage forms.

The defining structural feature of inland marine: it covers moveable property and exposures the standard commercial property policy does not reach. Commercial property policies cover the building and contents at named locations; inland marine covers everything that moves between or beyond those locations.

The seven most common inland marine policy types

Inland marine is a coverage category, not a single policy. Common forms include:³

Contractor's equipment floater. Covers tools, mobile equipment, and machinery owned or rented by a contractor. The most common inland marine form for construction trades. Coverage typically extends to theft, accidental damage, and (in broader forms) flood and equipment breakdown.

Installation floater. Covers materials, supplies, and equipment from the time they leave the supplier through installation. Used by contractors during the installation phase of a project, when the materials are not yet covered by the property owner's insurance and are not covered by the contractor's general property policy.

Builders risk. A specialized inland marine form for buildings under construction or renovation. Covers materials, fixtures, and equipment intended for permanent installation in the project. Most large construction projects require builders risk as a contract condition.

Transit / motor truck cargo coverage. Covers goods while being transported on company vehicles or common carriers. Required for trucking and freight operations; commonly added by any business shipping high-value inventory.

Bailee coverage. Covers customer property in the business's care for storage, repair, processing, or sale. Used by dry cleaners, jewelry repair shops, computer repair shops, and similar service businesses.

Computer / electronic data processing (EDP) coverage. Specialized coverage for computer hardware, software, and electronic data — typically broader than the equipment coverage in a standard commercial property policy.

Fine arts and valuable items. Specialized coverage for art collections, jewelry, antiques, and other high-value items where the standard commercial property limits are inadequate.

Who needs inland marine insurance

The clearest cases:

General contractors, HVAC contractors, electricians, plumbers, roofers, landscapers, and other construction trades — for tools, mobile equipment, and materials in transit.
Trucking and freight operations — for cargo and motor truck cargo coverage.
Photographers — for cameras, lenses, lighting, and equipment at events and shoots.
Mobile service businesses — locksmiths, mobile mechanics, mobile pet groomers, food trucks.
Cleaners and janitorial services — for equipment moved between client sites.
Jewelers and watch repair shops — for both inventory and customer property.
Trade show exhibitors — for booth equipment and inventory at shows.

For most of these businesses, inland marine is not optional. Standard commercial property and BOP policies have explicit "off-premises" limitations — typically $1,000 to $25,000 of off-premises coverage, far below the actual exposure most contractors and mobile businesses carry in tools and equipment.⁴ Inland marine is what closes that gap.

What inland marine does not cover

Inland marine policies have specific exclusions worth understanding:²

Wear and tear, deterioration, and mechanical breakdown. Covered separately by equipment breakdown insurance.
Vehicle damage from accidents. Covered by commercial auto, not inland marine.
Employee dishonesty. Covered by commercial crime or fidelity bonds.
Damage caused by faulty workmanship. General exclusion across most commercial property forms.
War, government action, and nuclear hazard. Standard exclusions across nearly all commercial property forms.
Some weather perils on outdoor property. Coverage for outdoor property, equipment left in the open, and similar exposures may have specific limits and conditions worth verifying against actual operations.

Cost of inland marine insurance

For full cost analysis with industry breakdowns, top carriers by published starting price, and 2026 benchmark data, see our inland marine insurance cost guide.

Inland marine premiums vary substantially by what is being covered and the value at risk. Rough benchmarks:

Contractor's equipment floater: $30 to $200/month for a small contractor with $25,000 to $100,000 in tools and equipment.
Builders risk: 1 to 4 percent of total project cost, depending on construction type, location, and project duration.
Motor truck cargo: $50 to $400/month for typical small trucking operations, scaling with cargo value and operating territory.
Bailee coverage: $20 to $150/month depending on customer property values held.

Insureon's data shows most small business inland marine policies cost between $20 and $500 per month, with median pricing varying widely by business type.⁴ For full cost methodology, see our 2026 small business insurance cost guide.

The variables underwriters use:

Total insured value (TIV) of property covered. The biggest single driver.
Type of property. High-theft items (electronics, jewelry, copper) price higher than commodity construction materials.
Operating territory. Urban operations price higher than rural for many forms.
Loss history. Prior claims affect renewal premiums materially.
Storage and security practices. Documented security (locked storage, GPS tracking on vehicles, alarmed yards) reduces premium.

How inland marine relates to other policies

Inland marine sits alongside, not inside, the other major commercial lines. The interactions:

Commercial property covers the building and contents at named locations. Inland marine covers property that moves or sits temporarily off-premises. The two policies are complementary; most contractors carry both.
BOP bundles GL with limited commercial property. The off-premises limitations on a standard BOP make inland marine necessary for any business with substantial off-premises exposure.
General liability covers third-party bodily injury and property damage. Inland marine covers your own property. These do not overlap.
Commercial auto covers the vehicle itself and liability from vehicle accidents. Cargo carried in a vehicle is typically covered by motor truck cargo (an inland marine form), not commercial auto.
Equipment breakdown covers mechanical and electrical breakdown of equipment. Inland marine covers external loss (theft, accidental damage); equipment breakdown covers internal failure.

State requirements

Inland marine is not legally required by any state. Functional requirements come from:

Construction project contracts. Most large general contractors require subcontractors to carry contractor's equipment and (for installation projects) installation floater coverage. Builders risk is typically required by project owners or lenders for any construction over $1M project value.
Lender requirements. Equipment financing typically requires inland marine coverage on the financed equipment as a condition of the loan.
Trade show contracts. Most major trade shows require exhibitors to carry inland marine on booth equipment and inventory.

Frequently asked questions

Why is it called "inland marine" if it does not cover boats?

The name dates to the 19th century, when ocean marine insurers extended their cargo coverage to goods continuing inland by rail or truck. The "inland marine" category eventually expanded to cover all moveable property and off-premises exposures, but the name stuck. Today, inland marine has no boat or water-related connotation in commercial usage.³

Do I need inland marine if I have a BOP?

Probably yes, if you have meaningful off-premises property. Standard BOPs limit off-premises coverage to small dollar amounts ($1,000 to $25,000) — far below most contractors' or mobile businesses' actual exposure. Inland marine extends coverage to your full property values wherever they are.

What is the difference between inland marine and ocean marine?

Ocean marine covers property and liability for waterborne shipping and ocean cargo. Inland marine covers everything else — property in transit by land, off-premises business property, specialized property categories. The two are distinct insurance categories with different forms, regulators, and underwriting practices.

Can I add inland marine to my existing commercial property policy?

Yes. Many carriers offer inland marine as endorsements to commercial property or BOP policies, particularly for smaller exposures (contractor's tool coverage up to $25,000 to $50,000, basic transit coverage). Standalone inland marine policies are typically used for larger exposures or specialized forms (builders risk, motor truck cargo, fine arts).

Is inland marine tax deductible?

Yes. Premiums for ordinary and necessary commercial insurance are deductible business expenses under IRS rules. Verify with a CPA for your specific situation.
