E-commerce business insurance: coverage, requirements and costs

An online seller's biggest exposure is the product, not the website. Your commercial general liability policy with products-completed operations coverage pays when something you sold injures a customer or damages property, and it is the policy the marketplaces ask to see. Cyber, stock in transit and at warehouses, and intellectual property claims come next. The 2022 NAICS has no separate "online retailer" code; the Census Bureau classifies an online store by the goods it sells, which is also how underwriters rate it.

Why e-commerce businesses need business insurance

An e-commerce business can be a single person with a garage and a Shopify store, or a company moving millions of units through marketplaces. Either way the seller is part of the distribution chain. In most states an injured consumer can name the manufacturer, the importer, the distributor and the retailer, and the one with the most reachable assets or the clearest insurance gets sued. If you private-label, import or "white-label" a product, you are treated as the manufacturer.

Beyond products there are costs that stores with a physical shop do not face: card-not-present fraud, customer data held on a hosted platform, listings built with photos and descriptions that someone else owns, and goods in somebody else's warehouse.

Core coverages

• General and product liability. Look at the products-completed operations aggregate, the territory (are sales to Canada or abroad covered?) and exclusions for categories such as children's products, supplements, vapes, e-bikes or lithium batteries. Many carriers decline or sublimit those. See product liability insurance for makers, sellers and importers.
• Commercial property and stock. Your policy may limit property away from your premises. If stock sits at a fulfillment center, a 3PL or a freight forwarder, ask whether it is covered there and at what limit; an inland marine or stock floater may be needed. See inland marine.
• Cargo and shipping. Carriers pay limited declared value. For high-value shipments or imports, see ocean marine and cargo insurance: how shipment and vessel coverage works.
• Cyber. Covers breach response, extortion and, depending on the form, business interruption from a platform or payment outage. A standard CGL excludes most electronic data losses. See does a small business need cyber insurance? and the cyber insurance readiness checklist.
• Crime and social engineering. Fake invoices, redirected supplier payments and hijacked accounts are standard fraud losses. Computer-fraud and social engineering fraud coverage is not in a basic BOP.
• Media or IP liability. The CGL's personal and advertising injury coverage (personal and advertising injury) includes some advertising offenses, but many forms carve out intellectual property infringement except copyright in your advertisement. Check the wording, and see media liability insurance: defamation, copyright and content claims.
• Workers' compensation. Required for employees in a warehouse or pack room; the exposure is lifting and forklifts.

Coverage you may be required to carry

Marketplaces. Amazon's published insurance requirement, as quoted by Jungle Scout, applies once a seller exceeds $10,000 in gross proceeds in a month, with 30 days to comply. It asks for at least $1 million per occurrence and in the aggregate, a deductible no higher than $10,000, and Amazon.com, Inc., its affiliates and assignees as additional insureds. Rules change; confirm the current text in Seller Central before you buy.

Walmart. Walmart's insurance requirements for suppliers providing goods for resale on any Walmart platform call for general liability of $1 million per occurrence and $2 million aggregate, product liability limits set by a product-category matrix, waiver of subrogation, primary and non-contributory wording, and an insurer rated B+ or better by AM Best (Walmart insurance requirements). Walmart says suppliers may be exempt from some requirements under a revenue threshold; whether a third-party marketplace seller falls under it depends on the program, so ask Walmart's compliance team.

Wholesale and brand agreements. Brands often require you to carry product liability and name them as additional insured. Run the paper through the contract insurance requirements checker and read how to review the insurance requirements in a contract.

Federal product rules. Consumer product sellers must follow CPSC rules. The CPSC says importers of most regulated consumer products must file certificates of compliance electronically with Customs (eFiling began July 8, 2026), and Section 15(b) requires a report to the agency within 24 hours of learning of a reportable defect or hazard. Civil penalties run to $120,000 per violation and $17.15 million for a related series. Insurers typically do not pay fines and penalties; see are fines, penalties and punitive damages insurable?.

Workers' compensation is a state requirement; see workers' comp requirements by state: who must carry it.

Common claims and how to prevent them

• Product injury. Keep supplier certificates, test reports and lot numbers. A seller without paperwork cannot pass the claim back to the manufacturer.
• Lost or damaged inventory. Reconcile warehouse reports against your own count monthly and document claims promptly.
• Account takeover. Use multi-factor authentication on the storefront, email, payment processor and marketplace accounts.
• Listing disputes. Use images and text you own or license. Takedown notices lead to suspended listings, which no policy pays for.
• Business email compromise. Call a known number before changing supplier bank details.
• Recalls. Record where each lot went and have a notification plan. A recall costs money even when no one is hurt; see product recall insurance.

What drives the cost

• General and product liability: annual gross sales as the exposure base (some carriers use units), product categories, the share imported or private-label, countries of origin, and sales channels.
• Property and stock: peak inventory value, where it sits, and the construction of any warehouse you run.
• Cyber: revenue, record counts, payment handling, security controls, and any prior incidents.
• Workers' compensation: payroll by class code.
• Loss history and controls: supplier vetting, recall plans, and years in business.

Underwriters ask what you sell, who makes it, whether you import, whether you hold the stock yourself or ship from a 3PL, and your biggest channels. Misdescribing products to get a lower rate is the usual route to a coverage dispute.

Specialized coverages to consider

• Product recall or contamination cover for consumables and children's goods.
• Umbrella liability when a marketplace or big customer wants $2 million or more.
• Stock throughput or cargo for imports.
• Contingent business interruption for a single key supplier or platform outage; see contingent business interruption insurance and supply chain risk.
• Errors and omissions if you also provide services such as custom design or installation.

How to buy

Online carriers such as biBERK and NEXT offer packages for online sellers (NEXT), and are quick for marketplace certificates. Sellers of higher-risk goods, importers and multi-channel companies should use an independent agent, because exclusions and sublimits are where small-seller policies fail. Have ready: sales by channel and category, supplier list with countries, product liability certificates, your marketplace insurance text, inventory locations and values, and loss runs.

Key takeaways

• Product liability is the core coverage; check territory and product-category exclusions.
• Marketplaces set their own insurance rules; read the current text before you buy.
• Stock at a 3PL or fulfillment center may fall outside a basic property policy.
• Cyber and social-engineering fraud are separate from general liability.
• Keep supplier certificates and lot records; they decide who ends up paying a product claim.
