This is general education, not insurance or legal advice — confirm actual coverage needs with a licensed insurance broker familiar with ecommerce, since requirements vary by product category, sales volume, and the marketplaces you sell on.

What's often required, not just optional

Some marketplaces require proof of product liability insurance (via a Certificate of Insurance) once a seller reaches a certain sales volume, or for specific product categories with inherently higher liability risk (anything ingested, applied to skin, used by children, or with obvious injury potential). Check the specific requirements for each marketplace you sell on — a requirement that doesn't apply at launch can apply once your sales volume crosses a threshold, so it's worth knowing in advance rather than being surprised later.

The two main types of coverage relevant to ecommerce sellers

  • General liability insurance covers third-party bodily injury or property damage claims not specifically tied to a product defect — for example, an incident at a trade show booth or warehouse you operate.
  • Product liability insurance covers claims that your product itself caused injury or damage — this is the coverage most directly relevant to a physical-product ecommerce business, and the one marketplaces most commonly require proof of for higher-risk categories or volume tiers.

Many small ecommerce sellers obtain both together through a Business Owner's Policy (BOP), which bundles general liability with property coverage and sometimes product liability, often at a lower combined cost than purchasing each separately — confirm with a broker whether product liability is included or needs to be added.

How to think about whether you need coverage now

  • If your product category carries real injury/health risk (ingestible, topical, children's products, electronics with fire/shock risk): prioritize getting product liability coverage before your first real sale, not after a marketplace requires it.
  • If a marketplace you're applying to already requires proof of insurance at your current or expected volume: you'll need coverage in place before that application can complete regardless of your own risk assessment.
  • If your product is genuinely low-risk and no marketplace you sell on currently requires it: it's a reasonable business decision to wait, but revisit the decision as sales volume grows — many sellers add coverage once they cross a marketplace's stated threshold or once the financial downside of an uninsured claim would be genuinely damaging to the business.

What a policy typically costs and what affects the price

Premiums vary based on your product category's inherent risk, your annual revenue/sales volume, and your coverage limits — a low-risk product (a basic accessory) at modest volume commands very different pricing than a higher-risk category (a supplement, a children's toy) at high volume. Get quotes from more than one broker who specifically writes policies for ecommerce/product sellers, since general small-business insurance agents may not be familiar with marketplace-specific requirements like Certificates of Insurance naming the marketplace as an additional insured.

What to have ready when getting a quote

  • Your product category and a description of the product (including any relevant materials, ingredients, or intended use).
  • Your actual or projected annual revenue and unit sales volume.
  • Which marketplace(s) you sell on, and their specific insurance requirements (some marketplaces publish a minimum coverage amount and require the marketplace to be named as an additional insured on the certificate).

Common mistakes

  • Waiting until a marketplace rejects an application or flags an account for missing required insurance, rather than checking requirements proactively.
  • Buying a generic small-business policy that excludes product liability, assuming it's covered when it isn't.
  • Underestimating coverage limits relative to what a marketplace specifically requires, resulting in a certificate that technically doesn't satisfy the requirement.

A simple decision checklist

  1. Check whether any marketplace you sell (or plan to sell) on requires proof of insurance at your category or volume.
  2. Assess your product's inherent injury/liability risk honestly, independent of whether it's currently required.
  3. Get quotes from at least one broker experienced with ecommerce/marketplace sellers specifically.
  4. Confirm the policy explicitly includes product liability, not just general liability, if that's your actual exposure.
  5. Revisit the decision as sales volume grows, even if you initially decided coverage wasn't yet necessary.
