Inland marine insurance covers manufacturers' equipment, raw materials, finished goods, and tooling while in transit, at job sites, or temporarily stored away from the primary facility — gaps that a standard commercial property policy does not fill. Premiums typically run $500–$4,500 per year for small to mid-size manufacturers. Who this is for: fabricators, OEMs, job-shop machinists, and any manufacturer moving product or equipment off-site.
TL;DR / Key Takeaways
- A standard commercial property (BOP or CPP) policy covers assets only at the named location; inland marine fills the transit and off-premises gap.
- Manufacturers most commonly need three inland marine forms: Contractor's Equipment Floater, Installation Floater, and Cargo/Motor Truck Cargo for outbound shipments.
- Limits should match the maximum value of goods in transit or off-site at any one time — not the aggregate annual value.
- Coverage is written on either a scheduled (per-item) or blanket basis; blanket is simpler to administer but requires accurate total-value estimates to avoid a coinsurance shortfall.
- Inland marine claims are typically settled faster than property claims because the forms carry fewer coverage conditions.
What Does Inland Marine Insurance Cover for Manufacturers?
Inland marine is a broad "floater" category that follows property wherever it goes. For manufacturers, covered property typically includes:
| Property Type | Common Coverage Trigger | Typical Valuation |
|---|---|---|
| Raw materials in transit (inbound) | Theft, collision, fire while in carrier's custody | Replacement cost or invoice value |
| Finished goods in transit (outbound) | Same perils plus over-the-road accidents | Replacement cost or selling price |
| Dies, molds, and tooling at vendor sites | Physical damage or disappearance | Actual cash value (ACV) or replacement cost |
| Customer-owned material in your custody | Damage during processing or transit | ACV or agreed value |
| Equipment loaned to or at a job site | Theft, vandalism, weather | Replacement cost |
| Prototype/R&D equipment off-site | Broad named-peril or open-peril | Agreed value |
What is typically excluded: Inland marine does NOT cover market loss, gradual deterioration, mechanical breakdown, or inherent vice (e.g., product that spoils because of its own chemistry). Earthquake and flood are usually excluded but can be endorsed for additional premium.
How Much Does Manufacturers Inland Marine Cost?
Premium is driven by four factors: (1) total insured value (TIV) in transit or off-site, (2) commodity type and susceptibility to loss, (3) claims history, and (4) deductible selected.
| Manufacturer Type | Typical Annual TIV Exposed | Estimated Annual Premium |
|---|---|---|
| Small metal fabricator (job shop) | $50,000–$150,000 | $500–$1,200 |
| Mid-size plastics / injection molding | $150,000–$500,000 | $1,200–$2,800 |
| Electronics or precision instruments | $200,000–$750,000 | $2,000–$5,500 |
| Heavy equipment / capital goods | $500,000–$2,000,000 | $3,500–$10,000+ |
| Food & beverage (perishables) | $100,000–$400,000 | $1,500–$4,000 |
Ranges are illustrative estimates for 2024–2025 market conditions. Actual premiums depend on carrier, loss history, deductible, and specific commodity. Perishable-cargo premiums can be 30–60% higher than dry-goods equivalents.
Deductibles commonly run $1,000–$5,000 per occurrence for transit coverage. Increasing the deductible from $1,000 to $2,500 typically saves 10–18% on premium.
Inland Marine vs. Commercial Property: What's the Difference?
Manufacturers often discover the gap after a loss. Here is a direct comparison:
| Feature | Commercial Property (BOP/CPP) | Inland Marine Floater |
|---|---|---|
| Where property is covered | Named premises only | Anywhere — in transit, at vendors, job sites |
| Coverage trigger | Named perils or special form | Open perils (most forms) |
| Property in the care of a carrier | NOT covered | Covered |
| Dies/molds at supplier | Usually excluded | Covered under tooling floater |
| Limit structure | Per-location aggregate | Per-shipment or blanket |
| Coinsurance requirement | Often 80–90% | Usually none (blanket forms) |
| Premium basis | Building + BPP values | Scheduled values or sales volume |
How to Buy Manufacturers Inland Marine in 5 Steps
- Inventory your off-premises exposures. List all property that regularly leaves your facility: outbound finished goods, tooling at vendors, demo equipment, raw materials in transit from suppliers. Assign a maximum value-at-any-one-time figure to each category.
- Choose scheduled vs. blanket coverage. Scheduled coverage lists individual items with specific values (best for high-value tooling or custom dies). Blanket coverage insures a class of property up to a single limit (better for fungible inventory in transit).
- Select valuation basis. Replacement cost pays the current cost to replace with like kind and quality. ACV subtracts depreciation. For finished goods, "selling price" endorsements are available and cover lost margin on outbound shipments — important for manufacturers with high value-added margins.
- Coordinate with your carrier's liability. If you are shipping under a bill of lading, the motor freight carrier's liability is governed by the Carmack Amendment and may be limited to $0.50–$5.00 per pound. Your own cargo policy fills the gap between carrier liability and actual value.
- Bind coverage and request certificates. Many customer contracts require proof of inland marine coverage. Request a certificate of insurance (COI) from your broker confirming limits and named-peril scope.
Real-World Scenario: CNC Tooling Floater + Cargo Coverage
Situation: A mid-size Ohio precision-machining shop produces aerospace components. They maintain a set of 14 custom CNC fixtures and dies valued at $380,000 — half stored at their facility, half on loan at a Tier-2 supplier 60 miles away. They also ship finished parts weekly via LTL carrier with an average outbound shipment value of $45,000.
The gap: Their existing BOP covers property at the named premises only. The dies at the supplier are uninsured. Their LTL carrier's liability is capped at $0.50/lb; a 200-lb shipment worth $42,000 would recover only $100 in a total loss.
Coverage arranged (illustrative): - Tooling/Dies Floater: $380,000 blanket limit, replacement cost, $2,500 deductible — estimated premium $2,100/year - Cargo Floater (outbound): $50,000 per-shipment limit, open perils, $1,000 deductible — estimated premium $1,400/year - Total added inland marine spend: ~$3,500/year
Outcome: When a forklift accident at the supplier damaged three dies worth $68,000, the tooling floater paid $65,500 (after deductible), fully restoring production capacity within six weeks. Without the floater, the shop faced a contract penalty clause of $15,000/month for delayed deliveries.
This scenario is illustrative. Premium estimates and claim outcomes vary by insurer, state, and specific facts.
Frequently Asked Questions
Does my BOP or commercial property policy cover goods in transit? Generally no. Standard BOP and CPP property forms cover business personal property at the described premises. "Property off premises" extensions exist but are typically sublimited to $10,000–$25,000 and exclude property in the custody of a common carrier. A dedicated inland marine cargo or floater policy is required for meaningful transit protection.
What is a blanket inland marine policy vs. a scheduled policy? A scheduled policy lists each piece of property (e.g., "Die Set #7 — $45,000") and pays only for scheduled items. A blanket policy covers an entire class of property up to an aggregate limit without itemizing. Blanket is administratively simpler but requires an accurate total-value estimate; if you under-report, recovery is proportionally reduced.
Does inland marine cover my finished goods if a customer refuses delivery due to damage? Yes, if the damage occurred during transit and is covered under the policy. Many cargo forms include a "selling price" valuation clause that pays the invoice value (cost + margin) rather than just your production cost — an important distinction for manufacturers with high value-added products.
Are custom dies and molds covered under inland marine? Yes. A Manufacturers' Dies, Molds & Patterns Floater (or similar form) is one of the most commonly purchased inland marine coverages for manufacturers. It covers dies and tooling at your facility, at suppliers' facilities, and in transit. Valuation is typically replacement cost or agreed value, because ACV on a custom die is often near zero.
How does inland marine interact with a customer's property in my custody? If a customer sends raw material or components to you for processing, that property is in your "care, custody, and control." A standard general liability policy typically excludes damage to property in your care, custody, and control. A Bailee's Customer Coverage form (a type of inland marine) fills this gap and covers customer property while in your shop or in transit.
What deductible should a manufacturer choose for inland marine? For cargo/transit coverage, a $1,000–$2,500 per-occurrence deductible is common and balances frequency risk against premium savings. For high-value tooling floaters, $2,500–$5,000 deductibles are typical. Manufacturers with strong cash flow and low loss frequency often benefit from higher deductibles; those shipping daily should model the expected annual loss frequency before raising deductibles.
Is earthquake or flood covered under a standard inland marine policy? No. Earthquake and flood are standard exclusions but can sometimes be endorsed back in, particularly for transit coverage (goods damaged in a flood while aboard a truck, for example). Ask your broker whether your commodity and transit routes warrant adding these endorsements.
Does inland marine cover employee theft of inventory? No. Employee theft (including inventory) is covered under a Crime or Fidelity Bond policy, not inland marine. Inland marine covers fortuitous, external perils (fire, theft by a third party, accident) but not dishonesty by insured's own employees.
