Standard property insurance covers inventory at a fixed location. But CPG brands move product constantly — from co-packer to 3PL to distributor to retailer. Here's where standard property coverage ends and inland marine begins.
Standard commercial property insurance is written to cover a fixed location — a warehouse, an office, a production facility. The policy covers property at the named location against specific perils: fire, theft, vandalism, certain weather events. What it explicitly does not cover is property that moves. Inventory in transit — on a truck, in a freight carrier's possession, moving from your co-packer to your 3PL — is not at your fixed location, and standard property policies exclude it accordingly.
The exclusion isn't always obvious in the policy language. Standard property policies often include "property off-premises" coverage, but that provision has strict limitations on what it covers and where. Coverage may apply to property temporarily off-premises — your employee's laptop at a trade show, or a small amount of product samples. It does not apply to full inventory shipments, palletized freight, or goods stored at third-party facilities. Reading the "off-premises" provision carefully reveals the coverage is far narrower than the name implies.
For CPG brands, the inventory movement pattern is constant and significant. A brand with $300,000 in finished goods might have $80,000 at the co-packer, $120,000 in transit, $60,000 at the 3PL, and $40,000 in transit to distributors at any given moment. Under a standard property policy, only the $40,000 at the brand's own location (if they have one) is covered. The other $260,000 is uninsured for transit and third-party location losses — and that's the inventory that's moving and therefore most at risk.
Temperature-sensitive products have an additional layer of exposure that standard property coverage doesn't address. Refrigerated goods — cold-pressed juices, fresh snacks, refrigerated beverages — are at risk from temperature excursion events during transit. A refrigerated truck breakdown, a cold storage failure at a 3PL, or a temperature excursion during a multiday cross-country shipment can destroy an entire pallet of refrigerated inventory. Standard property insurance doesn't cover temperature-related spoilage during transit. Inland marine policies with spoilage coverage do.
Inland marine insurance is a broad category that covers property in motion and property at third-party locations. The name is historical — "marine" insurance originally covered goods transported over water, and "inland marine" covered goods transported over land. Today, inland marine is the catch-all policy category for any property that doesn't fit the fixed-location model of standard commercial property coverage. For CPG brands, it's the solution to the transit and off-premises inventory gap.
A well-structured inland marine policy for a CPG brand covers inventory in transit (regardless of the carrier or transit method), inventory stored at 3PLs and co-packers, samples and display units at trade shows and pop-up retail events, and goods at distributor warehouses pending delivery. The coverage is typically written on an "all-risk" basis — meaning it covers all causes of loss except those specifically excluded — which is broader than the named-peril approach of standard property insurance.
The key policy parameters to understand are the coverage territory (domestic transit only, or international?), the valuation method (replacement cost or actual cash value?), and any per-shipment or per-location sublimits. For brands moving large single shipments — a full truckload to a major distributor — the per-shipment limit is the critical number. A policy with a $50,000 per-shipment limit that you're using to cover $200,000 truckloads has a built-in 75% coverage gap. Sublimits must be sized to your actual shipment values, which change as your business scales.
Temperature-controlled goods require an endorsement specifically addressing spoilage and contamination arising from temperature excursions. Not all inland marine policies include this by default — it's underwritten separately because temperature risk is actuarially distinct from physical damage risk. If your product requires refrigeration or temperature control at any point in the supply chain, your inland marine policy needs explicit temperature-spoilage coverage that covers the full transit and storage chain, not just the physical damage scenarios.
Third-party logistics providers — 3PLs — carry their own property insurance. When brands first discover the inland marine gap, they sometimes assume that the 3PL's policy covers their inventory. It doesn't — or rather, it covers it in a very limited way that typically leaves the brand exposed for most realistic loss scenarios.
A 3PL's property insurance covers the 3PL's own property: their warehouse, their equipment, their vehicles. Their liability for your inventory is governed by their service agreement, not their property policy. Most 3PL service agreements cap liability at a very low dollar amount — often $0.50 per pound (a federal standard for trucking carriers) or a contractual cap of $50–$100 per pallet. A pallet of premium CPG product worth $15,000 at retail is covered for $50 under a standard 3PL liability cap. That is not insurance — it's a contractual limit that protects the 3PL, not you.
Even 3PLs that carry bailee coverage (insurance that covers property in their custody) typically limit their bailee coverage to a fraction of the total inventory value in their facility and have exclusions for specific causes of loss. The 3PL's carrier won't pay a claim for your inventory's full value — they'll pay up to their bailee limit, per their policy terms, which often exclude the causes of loss that actually resulted in your inventory damage. Getting a copy of the 3PL's bailee coverage certificate and reviewing the limits and exclusions is a basic due diligence step that most CPG founders skip.
The practical solution is straightforward: your own inland marine policy should specifically name your 3PL locations as covered premises. This extends your inland marine coverage to inventory stored there, covers the gap that the 3PL's liability cap creates, and ensures that if there's a loss, your carrier handles the claim — not a dispute with the 3PL over their liability cap. Your carrier may then pursue the 3PL through subrogation if the 3PL's negligence caused the loss. That's the insurance system working correctly.
The operational coverage stack for a CPG brand with a typical supply chain — co-packer, 3PL, distributor, retail — needs three layers working together. Layer one is commercial property coverage for any locations you own or lease directly. Layer two is inland marine coverage for all inventory in transit and at third-party locations. Layer three is contingent property coverage for business interruption scenarios where your operations are disrupted because of a covered loss at a vendor's facility — your co-packer has a fire, your 3PL has a flood, and your brand loses revenue because your supply chain is down.
The inland marine policy is the most important layer for most early-stage CPG brands because most of them don't own or lease significant fixed property — they're asset-light by design. All of their inventory is either moving or at third-party locations. The entire value of their physical assets is exposed through transit and off-premises exposure. Getting inland marine coverage in place before a significant inventory event — a truck accident, a 3PL fire, a temperature excursion — is one of the highest-ROI risk management decisions a CPG founder can make.
Annual inventory value updates at policy renewal are critical for brands that are scaling. Inland marine policies are typically written based on your declared inventory value at the time of application. If your inventory value has grown from $200,000 to $800,000 in the past year — which is a normal growth trajectory for a brand moving from regional to national distribution — and you haven't updated your inland marine policy, you're underinsured by 75% at a minimum. Your coverage should scale with your business. That means reviewing your policy at every renewal and updating your declared inventory values to reflect current peak inventory levels, not the levels when you first bought coverage.
