Why Inventory Insurance Matters for Ecommerce Brands
Your inventory is the foundation of your ecommerce business. If a flood, theft, fire, or shipment loss wipes out stock, the financial impact can cripple operations overnight. Relying on your warehouse or 3PL’s insurance isn’t enough—those policies usually only cover their own liability, not your total exposure.
That’s why inventory insurance tailored to ecommerce is essential. With the right coverage, you can protect products across every stage: manufacturing, overseas shipping, warehousing, and customer delivery.
Types of Inventory Insurance Coverage
When searching for ecommerce inventory insurance, you’ll encounter several policy options. Each protects your stock at a different point in the supply chain:
- Business Personal Property (BPP): Covers inventory at a scheduled location you own or lease.
- Inland Marine (Goods in Transit): Protects goods while moving domestically (parcel, LTL, truckload).
- Stock Throughput Policy (STP): The most comprehensive option, covering goods from factory → ocean/air freight → warehouse → final delivery. Ideal for ecommerce brands scaling globally.
- Warehouse Legal Liability (WLL): Coverage held by your 3PL. Protects them—not you—if they are found negligent. It rarely covers full replacement value.
- Contingent Cargo: A backup if your carrier’s cargo policy fails.
For most ecommerce businesses, a stock throughput policy is the most seamless way to eliminate gaps between storage and transit.

Ecommerce Risks That Require Coverage
Ecommerce brands face unique inventory risks that traditional retailers don’t:
- Products stored across multiple facilities: 3PLs, FBA, overflow warehouses.
- Seasonality: Holiday sales can double or triple your average on-hand inventory.
- High in-transit volume: Fast replenishment cycles mean constant exposure during shipping.
- Theft-prone SKUs: Electronics, beauty, fragrance, and fashion items attract targeted theft.
- Fragile packaging: Glass, liquid, or temperature-sensitive goods raise spoilage and breakage risks.
Without proper limits and sublimits in place, these exposures can leave major gaps.
Key Decisions When Choosing an Inventory Insurance Policy
When evaluating policies, pay close attention to these areas:
1. Valuation
- At cost covers your wholesale cost.
- At selling price ensures you recover lost profit margins—vital for finished goods.
2. Policy Limits
Your limits should reflect:
- Peak season values (not just average).
- In-transit shipments.
- Catastrophic risks like flood, earthquake, or theft.
3. Coinsurance
Avoid penalties by insuring to full value. Ask about blanket limits or monthly reporting forms if inventory fluctuates.
4. Deductibles
Balance affordability and risk tolerance. Common ranges: $1,000–$5,000 for storage and $5,000+ for ocean shipments.
5. Perils Covered
Look for all-risk policies with theft, water damage, spoilage, and sprinkler leakage included.
6. Global Coverage
If importing goods, confirm the policy covers goods “on the water” and at international ports, bonded warehouses, and FBA centers.
How to Calculate Your Inventory Insurance Needs
A simple formula for ecommerce brands:
- Average on-hand value (12-month average).
- Peak season multiplier (usually 1.5–2.0).
- Highest single in-transit shipment value.
- Add 10–20% buffer for fluctuations.
Example:
- Avg. on-hand cost: $600,000
- Peak multiplier: 1.5 = $900,000
- Transit max: $200,000
- Subtotal = $1.1M
- With buffer = $1.25M
Recommended coverage: $1.25M blanket limit with sublimits for transit, theft, and spoilage.

Working with Your 3PL on Insurance
Many ecommerce brands assume their 3PL’s insurance protects their goods—it doesn’t. Here’s why:
- A 3PL’s Warehouse Legal Liability only covers damage caused by their negligence.
- Payouts are capped (often $0.50–$2.00/lb).
- Exclusions are common (natural disasters, hidden damage, etc.).
What you should do:
- Request your 3PL’s Certificate of Insurance.
- Maintain your own inventory insurance for full replacement coverage.
How to Keep Premiums Affordable
Insurance cost depends on facility protections, operational controls, and SKU profile. You can reduce premiums by:
- Choosing warehouses with sprinklers, CCTV, and restricted access.
- Implementing cycle counts and inventory accuracy audits.
- Providing underwriters with clean, consistent data on inventory values.
- Using carriers with strong loss ratios and claim histories.
Frequently Asked Questions
Does my 3PL’s insurance cover my products?
No. Their policy only covers their legal liability, usually with strict limits. You need your own coverage.
What’s the best insurance type for ecommerce brands?
A stock throughput policy usually offers the broadest and simplest protection.
Can I insure goods at selling price?
Yes, some insurers allow selling-price valuation, which covers profit margins.
Do I need to cover Amazon FBA inventory?
Yes. FBA reimbursements are not insurance and often fall short of full replacement value.
