Inland Marine Insurance: What It Costs, What It Covers, and Why Your Property Policy Leaves Equipment Exposed
Key Takeaways
- Your property policy stops at your front door: Standard commercial property insurance covers equipment and inventory at your listed business address. The moment it leaves — on a truck to a job site, at a client’s facility, in a temporary storage yard — coverage either drops to a sub-limit or disappears entirely
- Average cost: $0.80 per $100 of insured value: The standard rate for inland marine coverage is approximately $800/year per $100,000 in covered equipment, with a $1,000 deductible. Minimum premiums start at $500
- Contractors are the largest buyers: 70%+ of inland marine policies are written for construction contractors, electricians, plumbers, HVAC companies, and other trades that move expensive equipment between job sites daily
- Named perils vs open perils matters: Cheaper inland marine policies only cover named perils (fire, theft, collision). Open-perils policies cover everything EXCEPT what’s specifically excluded — the difference shows up at claim time when an unlisted cause of loss destroys your equipment
- Scheduled vs blanket coverage: Scheduling individual items (listing each piece with its value) guarantees agreed-value payouts. Blanket coverage covers all equipment up to a total limit but may result in disputes over individual item values at claim time
Inland marine insurance has the most confusing name in the industry — it has nothing to do with water. The name dates back to the 1800s when marine insurers extended their ocean cargo policies to cover goods moving overland by rail and truck. Today, inland marine is the go-to policy for any business that needs to insure equipment, tools, materials, or goods while they’re in transit, at a temporary location, or moving between job sites. For businesses with mobile equipment or goods in transit, inland marine insurance fills the gap that standard property policies leave open.
Inland marine coverage frequently overlaps with protecting and insuring valuable collections for items like fine art in transit, musical instruments, and scheduled jewelry that move between locations.
If your business owns equipment that leaves your premises — and nearly every contractor, tradesperson, medical practice, and technology company does — your standard commercial property policy is leaving a gap that inland marine fills. We structure inland marine programs for contractors with $50,000 in hand tools through operations with $5M+ in heavy equipment, matching the policy structure to how your equipment actually moves and gets used.
Inland Marine Insurance Cost by Equipment Value — 2026
| Equipment Value | Annual Premium | Rate per $100 | Typical Deductible |
|---|---|---|---|
| $25,000 (hand tools, small equipment) | $500 (minimum) | $2.00 | $500 |
| $100,000 | $700-$1,000 | $0.70-$1.00 | $1,000 |
| $250,000 | $1,500-$2,500 | $0.60-$1.00 | $1,000-$2,500 |
| $500,000 | $2,800-$4,500 | $0.56-$0.90 | $2,500-$5,000 |
| $1,000,000 | $5,000-$8,500 | $0.50-$0.85 | $5,000-$10,000 |
| $2,500,000+ | $10,000-$20,000+ | $0.40-$0.80 | $10,000-$25,000 |
Rates decrease as insured values increase (volume discounts). High-theft equipment (generators, compressors, copper) pays higher rates. Claims history is the largest premium variable.
Types of Inland Marine Coverage
Inland marine isn’t one policy — it’s a category containing multiple coverage forms, each designed for a specific type of movable property or business scenario. The most common forms for commercial operations are the contractor’s equipment floater, the installation floater, and the transportation/motor truck cargo form. Understanding which one you need prevents buying the wrong coverage.
| Coverage Form | What It Covers | Who Needs It |
|---|---|---|
| Contractor’s Equipment Floater | Owned/leased equipment at job sites, in transit, in storage | Construction, HVAC, electrical, plumbing, painting |
| Installation Floater | Materials and equipment awaiting installation at a client site | Contractors installing client-owned materials |
| Motor Truck Cargo | Goods being transported by your trucks for others | Trucking companies, freight haulers |
| Bailee’s Customer Property | Client property in your care, custody, or control | Dry cleaners, repair shops, warehouses |
| Electronic Data Processing (EDP) | Computers, servers, and data equipment in transit or off-site | IT companies, medical practices, mobile tech |
| Fine Arts Floater | Art, collectibles, and valuables in transit or on display | Galleries, museums, private collectors |
Case Study: Electrical Contractor Recovers $186,000 After Job-Site Theft
A 32-employee electrical contracting firm operating across three active job sites in the Houston metro area had $420,000 in equipment — wire spools, conduit benders, pull machines, generators, and hand tools — spread across sites and company vehicles. On a Friday night, thieves cut the fence at their largest job site and loaded $186,000 worth of copper wire spools and two portable generators onto a flatbed. The contractor’s commercial property policy excluded equipment at off-premises locations. Their inland marine contractor’s equipment floater (scheduled, open-perils, $420,000 limit with a $2,500 deductible) covered the full $186,000 loss minus the deductible. Claim was paid within 35 days. Without inland marine, the contractor would have absorbed the entire $186,000 — more than their annual profit margin on two of the three active projects.
Case Study: Medical Practice Saves $12,000 on Portable Diagnostic Equipment Coverage
A multi-location orthopedic practice with three offices across Miami-Dade County regularly transported $340,000 in portable MRI, ultrasound, and X-ray equipment between locations in company vans. Their commercial property policy covered the equipment at each listed office address but excluded transit between locations — a gap they discovered only when an ultrasound unit was damaged during transport ($28,000 repair). Our advisors structured a $340,000 EDP/medical equipment inland marine floater at $2,720/year (replacing a patchwork of three location-specific endorsements that cost $14,800 combined). The new floater covers all equipment at all locations and in transit for $12,080 less per year with broader coverage.
Frequently Asked Questions
What is the difference between inland marine and commercial property insurance?+
Commercial property covers your business assets at a fixed, listed location — your office, warehouse, or shop. Inland marine covers the same types of assets while they’re in transit, at temporary locations, at job sites, or otherwise away from your listed premises. Think of commercial property as coverage that’s tied to an address, and inland marine as coverage that travels with your equipment. Most businesses need both: property for what stays put, inland marine for what moves.
What does inland marine insurance cost?+
The average rate is $0.50-$1.00 per $100 of insured equipment value, with minimum premiums of $500. A contractor with $100,000 in tools and equipment pays $700-$1,000/year. A company with $500,000 in mobile equipment pays $2,800-$4,500/year. Rates decrease as insured values increase (volume pricing). The biggest premium drivers are equipment type (high-theft items like generators and copper cost more), claims history, security measures (GPS tracking, locked storage), and geographic area.
Does inland marine insurance cover theft?+
Yes — theft is one of the primary covered perils on both named-perils and open-perils inland marine policies. This includes theft from job sites, theft from vehicles, and theft from temporary storage locations. Some policies require specific security measures (locked vehicles, fenced job sites, GPS tracking on high-value items) as conditions of coverage. Mysterious disappearance (equipment that goes missing without evidence of theft) is covered under open-perils forms but typically excluded under named-perils forms.
Do I need inland marine if I have a business owners policy?+
Probably yes. A BOP includes limited coverage for business personal property, but it’s tied to your listed premises and typically caps at $10,000-$25,000 for property away from premises. If you regularly transport equipment worth more than that limit to job sites, client locations, or between offices, you need a standalone inland marine policy or a contractor’s equipment floater to cover the gap. The BOP off-premises sub-limit is almost always insufficient for trades with significant mobile equipment.
What is the difference between scheduled and blanket inland marine?+
Scheduled coverage lists each piece of equipment individually with its own insured value — you know exactly what’s covered and for how much. If a $45,000 excavator is stolen, the policy pays $45,000 (minus deductible) with no argument. Blanket coverage covers all equipment up to a total limit without listing individual items — simpler to administer but can lead to disputes over individual item values at claim time. For operations with a few high-value pieces, schedule them. For operations with hundreds of small tools, blanket is more practical. Many policies combine both: schedule items over $5,000-$10,000 and blanket everything below. For related coverage on construction projects, see our builders risk insurance cost guide.
