COVID-19 did not politely knock on the insurance industry’s front door. It kicked it open, tracked mud through the hallway, and asked everyone in inland marine insurance to explain where the forklifts, steel beams, electronics, medical supplies, generators, and half-finished buildings had gone. For agents, brokers, underwriters, contractors, logistics firms, wholesalers, and risk managers, the pandemic turned “property in transit” into “property stuck somewhere weird for longer than planned.”
That is why understanding COVID-19’s impact on inland marine exposures still matters. Inland marine insurance may sound like it belongs on a boat with a captain named Hank, but it usually protects movable property on land: construction equipment, tools, cargo, building materials, goods in temporary storage, installation property, fine arts, medical equipment, and other assets that do not stay nicely inside four permanent walls. When the pandemic disrupted work sites, supply chains, transportation routes, warehouses, labor availability, and project schedules, inland marine exposures changed almost overnight.
This guide breaks down what happened, why it mattered, and what businesses can still learn from the COVID-19 era. The short version: movement slowed, accumulation increased, security weakened in places, project timelines stretched, replacement costs rose, and policy wording became the star of the show. Not bad for a line of insurance many people still accidentally imagine wearing a sailor hat.
What Inland Marine Insurance Actually Covers
Inland marine coverage is designed for property that moves, property that is stored temporarily away from the main premises, or property that is exposed to transportation-related risks. Common examples include contractors’ equipment, builders risk, installation floaters, motor truck cargo, warehouse legal liability, bailees coverage, and electronic equipment coverage.
Unlike standard commercial property insurance, which usually focuses on buildings and business personal property at a scheduled location, inland marine policies often follow the property. That flexibility is powerful, especially for companies that operate on job sites, deliver goods, install systems, store inventory with third parties, or move equipment between locations. But flexibility also creates exposure. If a contractor’s excavator is parked at a shut-down site, if imported materials are delayed at a warehouse, or if customer goods are sitting in a third-party facility longer than expected, the risk profile can change quickly.
How COVID-19 Changed Inland Marine Exposures
COVID-19 affected inland marine insurance because it disrupted the two things inland marine depends on most: movement and control. Goods were delayed in ports, trucks waited for available drivers, construction projects paused, warehouses filled up, and businesses had to make fast decisions with incomplete information. In insurance terms, that means higher uncertainty. In ordinary English, it means everybody had a headache and the spreadsheet started smoking.
1. Construction Projects Stopped, Slowed, or Changed Shape
Construction was one of the most visible inland marine pressure points during the pandemic. Some projects were shut down by local restrictions. Others continued as essential work but had to operate with distancing, sanitizing, staggered shifts, fewer workers, or delayed inspections. Builders risk policies, contractors’ equipment policies, and installation floaters suddenly faced new questions.
When a project stops, the risk does not stop with it. In fact, idle sites can become more vulnerable. Materials may be exposed to weather for longer periods. Temporary fencing may be tested by trespassers. Expensive tools, copper wiring, lumber, steel, HVAC equipment, and appliances can attract thieves. Partially installed systems may be more vulnerable to water damage, fire, vandalism, or deterioration. A project that was supposed to be a busy construction site can become an oversized storage yard with questionable lighting and a lonely porta-potty.
COVID-19 also stretched timelines. Delayed permits, labor shortages, quarantine requirements, supply shortages, and inspection backlogs meant that projects could remain under construction longer than planned. This mattered because builders risk policies often have expiration dates, occupancy restrictions, testing limitations, soft cost provisions, and reporting requirements. Agents who treated the policy period as a minor detail learned very quickly that calendars can be expensive.
2. Cargo Spent More Time “At Rest”
Inland marine is not only about cargo moving from Point A to Point B. Sometimes the biggest exposure appears when cargo is not moving at all. During COVID-19, goods accumulated at ports, warehouses, distribution centers, terminals, trailers, rail yards, and temporary storage locations. That created a classic “cargo at rest” problem.
Cargo at rest can be vulnerable to theft, temperature variation, fire, water damage, spoilage, contamination, mishandling, and documentation errors. A shipment delayed for two days may be annoying. A shipment delayed for six weeks in a facility never designed for long-term storage is an underwriting conversation wearing a fake mustache.
High-demand goods were especially sensitive. Medical supplies, electronics, cleaning products, food, construction materials, and consumer goods all became more valuable or harder to replace at different points during the pandemic. When value rises and availability falls, theft risk often becomes more attractive to criminals. At the same time, overloaded warehouses and logistics bottlenecks can reduce visibility and increase errors.
3. Warehouses Became Risk Concentration Zones
Temporary storage is common in inland marine insurance, but COVID-19 turned some temporary storage into “temporary, but please do not ask how long.” Inventory that would normally move through the supply chain quickly stayed put. Businesses rented extra warehouse space, used overflow yards, parked loaded trailers, or relied more heavily on third-party logistics providers.
This changed exposure in several ways. First, values accumulated in fewer places. Second, storage conditions varied. Third, businesses did not always have the same control over third-party facilities that they had over their own premises. Fourth, policy limits and sublimits sometimes failed to match the new reality.
For example, a distributor might normally hold $500,000 of goods at one warehouse and another $500,000 moving through transit. During the pandemic, the same distributor might suddenly have $2 million sitting in one location because inbound shipments arrived but outbound deliveries stalled. If the inland marine policy had location limits, unnamed location restrictions, catastrophe sublimits, or reporting requirements, the coverage picture could change dramatically.
4. Theft and Vandalism Risks Increased at Some Sites
Theft has always been a major inland marine concern. COVID-19 did not invent jobsite theft, cargo theft, or equipment theft. It simply gave thieves more opportunities in certain situations. Empty construction sites, parked equipment, delayed shipments, unattended trailers, and crowded warehouses all created tempting targets.
Contractors’ equipment is particularly attractive because it is valuable, portable, and sometimes difficult to identify quickly. Skid steers, mini excavators, generators, compressors, tools, and trailers can disappear faster than a box of donuts in a claims department meeting. Materials such as copper, lumber, steel, and appliances also became theft targets as prices rose and shortages spread.
Risk control during the pandemic therefore became more important, not less. Strong fencing, controlled access, lighting, cameras, GPS tracking, locked storage, inventory logs, equipment identification, and frequent site checks helped reduce exposure. Businesses that cut security budgets to save money often discovered that a missing generator is a very persuasive accountant.
5. Supply Chain Delays Increased Replacement Cost Pressure
COVID-19 caused shortages and price volatility across many categories, including construction materials, electronics, vehicles, machinery, and parts. For inland marine insureds, this affected replacement cost, repair time, and business continuity. If a covered piece of equipment was damaged, replacing it was not always simple. If a shipment was lost, buying the same goods at the old price could be impossible.
This created tension around valuation clauses. Actual cash value, replacement cost, agreed value, selling price valuation, and reporting forms became more than fine print. They determined whether the policy reflected the real cost of loss in a disrupted market. Deductibles, coinsurance, margin clauses, and limits also deserved closer attention.
For agents and brokers, the lesson was clear: old schedules can become outdated quickly. A policy written before a major supply chain shock may not match current equipment values, material costs, freight charges, or inventory levels. Reviewing values became a practical necessity, not a paperwork hobby.
Coverage Questions COVID-19 Forced Into the Spotlight
COVID-19 did not create a single uniform coverage issue for inland marine insurance. Instead, it created many smaller questions that depended on policy wording, facts, timing, and documentation. The phrase “it depends” earned overtime pay.
Does the Policy Require Direct Physical Loss or Damage?
Many property and inland marine policies require direct physical loss or damage to trigger coverage. COVID-19-related delays, government orders, labor shortages, or supply chain interruptions may not qualify unless covered property has sustained actual physical loss or damage. That distinction became central during pandemic-related claims discussions.
For example, if a jobsite shut down because workers could not safely continue, the shutdown itself might not be covered under a builders risk policy. But if vandalism, theft, fire, water intrusion, or storm damage occurred during the shutdown, those physical losses might be evaluated under the policy terms. The difference is not academic; it is the difference between “claim discussion” and “awkward silence.”
Are Delay, Soft Costs, or Expediting Expenses Covered?
Some builders risk policies include soft cost coverage, delay in completion coverage, extra expense, or expediting expense endorsements. These forms can be useful, but they are usually tied to covered physical loss or damage. Pandemic delays alone may not be enough.
Policyholders needed to understand whether additional interest, taxes, legal fees, advertising costs, architectural fees, or other soft costs were covered. They also needed to know whether expediting expenses applied when materials were delayed due to supply chain disruption, or only after a covered cause of loss. The answer could vary widely.
What About Communicable Disease or Virus Exclusions?
Some policies include exclusions or limitations related to virus, contamination, pollution, communicable disease, or loss of use. Others may include limited coverage extensions. COVID-19 reminded everyone that exclusions are not decorative. They are not policy confetti. They matter.
Agents and insureds should review these provisions carefully, especially for businesses with high-value equipment, medical goods, food products, or property stored in controlled environments. Even when virus-related loss is not the main exposure, contamination concerns can affect cleaning costs, access, handling procedures, and operational delays.
Key Inland Marine Classes Affected by COVID-19
Builders Risk
Builders risk coverage was heavily affected because construction projects depend on labor, materials, inspections, schedules, and secure sites. COVID-19 disrupted all of them. The biggest exposure changes involved project shutdowns, extended policy periods, water damage prevention, fire protection, site security, temporary storage, and increased material values.
Best practices include reviewing project completion dates, requesting extensions early, documenting site protection plans, maintaining fire and water controls, securing materials, and confirming whether soft costs or delay coverage applies.
Contractors’ Equipment
Contractors’ equipment faced increased exposure when machinery sat idle or moved less frequently. Idle equipment can still be stolen, vandalized, damaged by weather, or suffer maintenance issues. During the pandemic, some companies also moved equipment to storage yards or different jobsites, creating potential scheduling and location issues.
Businesses should maintain updated equipment schedules, verify serial numbers, use GPS tracking where practical, inspect idle machinery, protect batteries and fluids, and avoid leaving small tools unsecured. A $60 padlock is not a complete risk management plan, but it is usually better than wishful thinking.
Installation Floaters
Installation floaters cover materials and equipment intended for installation, such as HVAC units, electrical systems, cabinetry, fixtures, medical systems, or specialized machinery. COVID-19 delays meant installation property sometimes remained in transit or storage longer than expected.
The main concerns included theft, damage before installation, storage location limits, delayed acceptance, and whether coverage ended once the item was installed, tested, or put to use. Contractors and subcontractors needed to coordinate closely with project owners and general contractors to avoid gaps.
Motor Truck Cargo
Motor truck cargo exposures changed as delivery routes, demand patterns, and warehouse congestion shifted. Some cargo moved faster due to urgent demand, while other cargo sat in trailers or terminals. Driver shortages, changing delivery windows, and increased pressure on logistics providers added complexity.
Motor carriers and shippers needed stronger documentation, route planning, seal controls, driver communication, trailer security, and claims reporting procedures. Cargo left unattended in an unsecured location can turn a normal shipment into an expensive lesson with wheels.
Warehouse Legal Liability and Stock Throughput
Warehouse legal liability and stock throughput coverage became more important as inventory accumulated and businesses relied on third-party storage. Warehouse legal liability generally responds to the warehouse operator’s legal responsibility, while stock throughput can provide broader protection for inventory from origin to final destination, depending on the policy.
COVID-19 showed why businesses should understand who is responsible for goods at every stage. A certificate of insurance is helpful, but it is not a magic shield. Contracts, warehouse receipts, bills of lading, policy limits, exclusions, and valuation terms all matter.
Risk Management Lessons for Agents and Businesses
Review Values More Often
Inflation, shortages, and replacement delays can make old insured values unreliable. Businesses should review equipment values, inventory levels, project values, and temporary storage exposures at least annually, and more often during volatile markets. Agents should ask whether clients have added new storage locations, changed logistics partners, or experienced project delays.
Do Not Ignore Temporary Storage
Temporary storage can quietly become the biggest exposure on the account. Businesses should know where property is stored, how long it will remain there, who controls it, what security exists, and whether the policy covers that location. “It is only there for a little while” is not a risk management strategy. It is a sentence that often appears before trouble.
Document Everything
COVID-19 proved the value of documentation. Jobsite photos, equipment lists, delivery receipts, inspection logs, maintenance records, incident reports, storage agreements, and communication with carriers can all matter during a claim. Good documentation does not guarantee coverage, but poor documentation can make a valid claim harder to prove.
Strengthen Site Security
Whether the site is active, paused, or waiting for materials, security should match the exposure. Recommended controls include controlled access, lighting, fencing, cameras, guards for high-value locations, locked containers, GPS devices, and regular inspections. The best security plan is layered. The worst one is “we think someone checks on it sometimes.”
Read the Policy Before the Problem
Inland marine policies are not identical. Coverage forms, exclusions, valuation clauses, reporting requirements, storage limitations, protective safeguards, and warranties vary. Agents should review policy language with clients before losses occur, especially when operations change. The middle of a claim is a terrible time to discover that a key exposure was never scheduled.
Practical Examples of COVID-19 Inland Marine Exposure Changes
Example 1: The Paused Apartment Project
A contractor pauses a multifamily housing project because inspections are delayed and several subcontractors are unavailable. HVAC units, appliances, copper wiring, and lumber remain onsite. Two weeks later, thieves enter through a weak section of fencing and steal materials. The builders risk claim may depend on whether theft is covered, whether protective safeguards were maintained, whether the project was properly secured, and whether the policy period remained active.
Example 2: The Overloaded Distributor
A distributor receives imported electronics but cannot deliver them to retailers because stores are closed or operating at reduced capacity. Inventory accumulates in a temporary warehouse. A fire damages a large portion of the stock. The key questions include whether the location was reported, whether limits are adequate, whether the storage facility meets policy requirements, and how the goods are valued.
Example 3: The Idle Excavator
A construction company parks several machines in a yard during a project delay. One excavator is stolen. The contractors’ equipment policy may respond, but the claim process will be smoother if the company has updated schedules, serial numbers, purchase records, photos, GPS data, and a police report. Insurance likes proof. It is old-fashioned that way.
Experience-Based Insights: What the COVID-19 Era Taught Inland Marine Professionals
The most valuable lesson from COVID-19 was not that every business needs more insurance. It was that every business needs insurance that matches how it actually operates when the world becomes messy. Before the pandemic, many companies treated inland marine coverage as a technical add-on. It was something purchased for equipment, cargo, or a construction project, then filed away until renewal. COVID-19 showed that inland marine exposures are living exposures. They change when a delivery is delayed, when a site closes, when inventory builds up, when a subcontractor cannot arrive, or when a warehouse becomes the accidental center of the universe.
One experience repeated across many industries was the discovery of hidden accumulation. A business might have believed its goods were spread across the supply chain, only to find that a large portion of its inventory was sitting in one warehouse. A contractor might have expected materials to arrive just in time, only to receive partial shipments that had to be stored onsite for weeks. A manufacturer might have depended on one logistics provider and then realized that a single bottleneck could affect production, storage, sales, and insurance values at the same time.
Another major experience involved communication. The strongest businesses were usually the ones that communicated early with agents, carriers, lenders, project owners, subcontractors, and logistics partners. They asked practical questions: Are our limits still enough? Is this temporary storage location covered? Do we need to extend the builders risk policy? What happens if materials arrive before the site is ready? Are our security controls adequate? These questions were not glamorous, but neither is finding out after a theft that nobody knows exactly what was stolen.
Claims experience also reinforced the importance of separating inconvenience from covered loss. Many businesses suffered real financial harm from delays, shortages, and shutdowns. But insurance coverage depends on policy language. Inland marine policies are generally designed to address physical loss or damage to covered property, not every economic consequence of a pandemic. That distinction frustrated many policyholders, but it also encouraged better planning. Businesses began looking more carefully at business interruption, contingent business interruption, trade disruption, stock throughput, delay in completion, and contract risk transfer.
Risk control habits improved too. Some companies adopted more frequent site inspections, better equipment tracking, stronger warehouse audits, and clearer procedures for idle property. Others updated emergency shutdown plans so that if another disruption occurs, they can secure sites quickly, protect materials, preserve fire systems, drain water lines where appropriate, and document the condition of property. The best plans were simple, assigned to specific people, and tested before the crisis. A plan that lives only in a binder is basically a decorative brick.
For agents, the experience was a reminder to ask better questions. Instead of simply renewing last year’s inland marine schedule, agents learned to ask about operational changes. Are clients using new storage locations? Are projects delayed? Are material values higher? Are shipments spending more time in transit? Are goods being stored with third parties? Are protective safeguards still in place? Has the client changed suppliers or carriers? These questions turn an agent from a policy processor into a risk advisor.
For underwriters, COVID-19 highlighted the importance of current information. Old statements of values, outdated equipment schedules, and vague storage descriptions became less reliable. Underwriters needed to understand not only what property was insured, but where it was, how it was protected, how long it stayed there, and how quickly it could be replaced. In a disrupted market, a risk that looked ordinary last year could become much more complex.
The final experience is simple: inland marine insurance is most valuable when it is treated as part of a broader resilience plan. Insurance can help after a covered loss, but it cannot unload a delayed ship, manufacture a missing part, replace a stolen machine overnight, or secure a jobsite by itself. Businesses that combine strong coverage with practical risk control, updated valuations, good contracts, and clear communication are better prepared for the next disruptionwhether it comes from a pandemic, a storm, a labor shortage, a cyber event, or some new surprise that walks in wearing muddy boots.
Conclusion
COVID-19 changed inland marine exposures by disrupting movement, increasing storage time, concentrating values, delaying construction, raising replacement costs, and exposing weaknesses in security and documentation. It also reminded businesses that inland marine insurance is not a set-it-and-forget-it product. It is closely tied to real operations, and real operations can change fast.
For contractors, distributors, logistics companies, manufacturers, and property owners, the lesson is clear: review coverage before disruption arrives. Confirm values, locations, transit exposures, storage arrangements, project timelines, and policy terms. For agents and brokers, the opportunity is just as clear: ask better questions, explain coverage triggers, and help clients build practical risk management habits.
The pandemic was a stress test, and not every inland marine program passed with a gold star and a confident handshake. But the industry learned. The businesses that apply those lessons now will be better prepared for whatever comes next. And if the next crisis involves forklifts, warehouses, half-built projects, and mysterious delays, inland marine insurance will once again be standing in the middle of the action, clipboard in hand.
