What does inland marine insurance cover—and when does a business need it?

By Mark Melliand, owner, Melliand Insurance Agency · 13 years as an independent agent · Published October 26, 2026

Short answer: Inland marine is a category of property insurance for property that moves, is used away from your premises, or is in your care for others. Common small-business examples are contractors’ tools and equipment, property in transit, and materials waiting to be installed. It isn’t one uniform policy. Different inland marine forms cover different property and activities, and the name doesn’t mean you ship goods by boat. What’s covered depends on the specific form: the property and interests insured, locations and territory, causes of loss, exclusions, valuation, limits, deductibles and endorsements.

What “inland marine” means

The Texas Department of Insurance says inland marine “covers property kept on land, not on water, despite its name,” and lists property in transit and contractor equipment among the kinds of property it can cover. TDI suggests asking your agent about inland marine if your business uses property your commercial property policy doesn’t cover (TDI).

The Hartford explains that the name traces back to ocean marine insurance for goods shipped by water. As shipping moved over land, the coverage evolved for property in transit and at changing locations (The Hartford). Travelers describes inland marine as “property coverage for material, products or equipment that moves or is transportable,” and says it can also cover certain property owned by others (Travelers).

Insurers offer many inland marine product lines, from construction to fine art to logistics. This guide focuses on the ones most small businesses ask about.

Common types for small businesses

  • Contractors’ tools and equipment. Sometimes called a contractor’s equipment floater. The Hartford describes coverage for “owned, leased, rented or borrowed equipment used in construction and related trades,” which may include smaller power and hand tools as well as machinery (The Hartford). Travelers says its coverage can include equipment acquired after the policy starts, for a period of time (Travelers).
  • Owned, rented or borrowed equipment. Whether rented or borrowed equipment is covered depends on the form. Liberty Mutual lists “equipment you have leased, loaned, or rented” and continuing lease and rental charges among its options (Liberty Mutual).
  • Property in transit. Coverage for your property while it’s being transported over land. The Hartford lists property “shipped or transported over land” as an inland marine area.
  • Installation materials. An installation floater covers materials and supplies headed for installation. Travelers describes coverage from when materials “leave the contractor’s business until they are installed and that job is signed off,” including transit and temporary storage, with some exclusions (Travelers). The actual form determines when coverage ends; do not assume job sign-off is the only termination event. The Hartford describes installation coverage for “personal property installed, fabricated or erected by a contractor” (The Hartford).
  • Property of others in your care. Some inland marine coverage applies to customers’ property while it’s in your care, custody or control. Travelers and The Hartford both describe this; the form’s terms decide when it applies.

None of these is automatically included in one policy. Ask which coverage parts you have and what each one covers.

Distinctions that matter

  • Your own goods vs. customers’ goods. Coverage for property you own is different from coverage for property you’re holding or working on for someone else. Check whether, and how, property of others is covered.
  • Equipment coverage vs. motor truck cargo. Contractors’ equipment coverage is about your tools and equipment. Motor truck cargo coverage is about goods you haul, often for others. Travelers lists transportation, cargo and logistics as a separate inland marine line. If you haul customers’ goods, see the cargo note in our commercial auto coverage guide.
  • Installation coverage vs. builders risk. The Hartford says installation coverage is “specific to the covered installation,” while a builders risk policy may cover an entire building project. Which applies depends on your role and the project. For more detail, see our guide to what builders risk insurance covers.
  • Loose tools vs. permanently attached vehicle equipment. Tools you carry in a vehicle aren’t the same as the vehicle or equipment permanently attached to it; our commercial auto coverage guide explains this. Don’t assume commercial auto physical damage covers loose tools or cargo, and confirm how attached equipment is treated.

Inland marine and your other coverage

Commercial property and BOP policies may extend some coverage away from your premises, but usually with conditions and limits. For example, the unendorsed illustrative standard commercial property form reviewed (ISO CP 00 10 10 12) includes a coverage extension, subject to the form’s eligibility conditions, for your property temporarily at locations you don’t own, lease or operate, in certain storage, or at fairs, trade shows or exhibitions. In that unendorsed form, the extension doesn’t apply to property in or on a vehicle and has its own dollar limit. Policies built on that base form may be endorsed differently, so don’t assume the same vehicle restriction or limits apply to yours. See our commercial property coverage guide.

Conditions and limits to review

Inland marine forms vary widely, so treat these as questions to ask about your specific form.

  • Scheduled vs. blanket. Is each item listed with a value (scheduled), or are items covered under a blanket limit? Are unscheduled small tools covered, and is there a per-item limit? The Hartford mentions coverage for “certain unscheduled or miscellaneous tools.”
  • Limits. What per-item, per-occurrence and total limits apply? Are there separate limits for employee tools, rented equipment or property in transit? The Hartford notes that employee-owned tools are “subject to policy limits.”
  • Valuation. Is property valued at replacement cost, actual cash value or another method, and does the method change with the age of the equipment? Liberty Mutual lists “Replacement cost or actual cash value” as options. Valuation terms are product-specific.
  • Deductibles. What deductible applies? Is it different by item or cause of loss? Liberty Mutual mentions deductible options “by specific equipment or cause of loss.”
  • Theft, unattended vehicles and security. Does the form cover theft from an unattended vehicle? Does it require the vehicle to be locked, or show signs of forced entry? Are there security conditions for job sites or storage?
  • Overnight storage and temporary locations. Is property covered while stored overnight at a job site, in a trailer or at a temporary location?
  • Causes of loss. Which causes of loss are covered and excluded? Flood, water damage and wind can be treated differently. Travelers says its contractors’ equipment coverage “can include” theft, vandalism and damage from fire and accidents. Its installation page notes exclusions for some transit by air or water and some underground work.
  • Mechanical breakdown, wear and tear, maintenance. Ask which exclusions or limitations apply to mechanical breakdown, wear and tear and maintenance-related losses.
  • Unexplained disappearance, inventory shortages and employee theft. How does the form treat property that’s simply missing, shortages found only on inventory, or theft by employees?
  • Newly acquired property and reporting. Is newly acquired equipment covered automatically for a period, and when must you report it? Travelers mentions coverage for later-acquired equipment “for a period of time.”
  • Rental expense or loss of use. If covered equipment is damaged, does the policy help with the cost of renting replacement equipment or continuing rental charges? Does a waiting period apply before that coverage starts, and what limit applies?

Some inland marine coverage is described as broad or open-perils coverage. Any form still has exclusions, conditions and limits; read them before relying on it.

Hypothetical examples: coverage-review questions

These are illustrations. They describe assumptions, not claim outcomes.

A contractor’s tools are stolen from a work vehicle overnight

Assume a contractor leaves tools in a parked work truck overnight, and they’re stolen. Questions to review:

  • Does the contractor have contractors’ equipment or other inland marine coverage that includes these tools?
  • Does the form cover theft from an unattended vehicle, and are there locking or forced-entry conditions?
  • Are the tools scheduled, or covered under a blanket or small-tools limit?
  • What deductible and valuation apply?
  • Does the commercial auto policy cover any of this? Loose tools generally need separate review.

Rented equipment is damaged at a jobsite

Assume a contractor rents a piece of equipment, and it’s damaged at a job site. Questions to review:

  • Does the contractor’s policy cover rented or leased equipment, and for what limit?
  • What does the rental agreement require the contractor to insure or pay for?
  • Does the policy cover continuing rental charges or the cost of renting a replacement?
  • Is the cause of the damage a covered cause of loss under the form?

Materials are damaged while being transported for installation

Assume a contractor is hauling materials to a project for installation, and they’re damaged in transit. Questions to review:

  • Does an installation floater or transit coverage apply while materials are on the way?
  • When does that coverage begin and end under the form?
  • Does the project have builders risk coverage, and who’s insured under it?
  • Are there exclusions for the type of transit or the cause of the damage?

Preparation checklist

  • A description of the property and who owns it
  • An inventory of tools and equipment, with values and identifying details such as serial numbers. See our guide to what information you need to insure your business’s tools and equipment.
  • A list of rented, leased or borrowed items, and the agreements that govern them
  • Where property is kept, stored overnight and transported
  • Security practices for vehicles, job sites and storage
  • Contracts that assign responsibility for property, including rental agreements and project contracts
  • Your existing property, BOP, auto and inland marine policies and endorsements

Don’t send serial-number lists, contracts or other sensitive records through an ordinary website form. Ask what’s needed and arrange an appropriate way to provide it.
