$5M Professional Liability (E&O) Insurance for Quality Control Inspectors

Quality control inspectors and inspection firms can meet a $5M Professional Liability (E&O) clause with one $5M policy or a smaller primary policy plus follow-form excess layers.

What does a $5M requirement mean for quality control inspectors?

Professional Liability (E&O, short for Errors and Omissions) covers claims that your inspection, report or sign-off caused a client a financial loss. A $5M clause might read:

• Per claim and aggregate: the most paid for one claim, and for all claims in one policy year. Both must reach $5M.
• Claims-made: Professional Liability almost always covers claims made and reported while the policy is active, for work done after the retroactive date (the earliest date of work the policy covers). See retroactive dates explained.
• Primary plus excess: this clause allows stacked policies. If yours is silent, confirm with the client that primary plus follow-form excess meets the clause.

Who asks quality control inspectors for $5M?

Many clients start at $1M or $2M. A $3M clause is the next step up, and $5M usually needs a larger primary limit or more excess layers. It appears when one missed defect could spread across a whole production run:

• Car makers (OEMs, short for original equipment manufacturers) and their direct suppliers using outside containment (extra inspection of suspect parts) on brake, steering or airbag parts.
• Aerospace and defense prime contractors relying on outside inspection of parts at the supplier's plant.
• Medical device manufacturers hiring firms to audit suppliers or inspect incoming components.
• Energy and utility companies buying vendor surveillance on pressure vessels, pipe, valves or turbine parts.
• Some government agencies on large or safety-critical programs, where the request for proposal (RFP) sets the limit.

How is $5M built?

Quality control firms often buy Miscellaneous Professional Liability, a form for service firms that have no policy type of their own. Firms that stamp work as licensed engineers often buy Architects and Engineers (A&E) Professional Liability instead.

A primary policy pays first. An excess policy pays only after the layer below it is used up. "$3M xs $2M" means a $3M layer above the first $2M.

Both a single $5M primary and a primary plus excess are used, depending on your size and inspection work. Each excess layer should follow form, meaning it uses the primary policy's terms. Many policies pay defense costs inside the limit, so confirm each layer treats defense the same way. A commercial umbrella almost never covers Professional Liability.

What will underwriters ask quality control inspectors for?

• Your services by share of revenue: source inspection (at the supplier's plant), receiving inspection, first article inspection (the first parts from a new run), sorting, containment, supplier audits.
• Revenue from aerospace, automotive safety, medical device, nuclear or energy clients, and whether you release product or only report findings.
• Inspector certifications, subcontractor supervision, and calibration controls.
• Your client contracts, including any limitation of liability clause (a cap on what you owe a client).
• Three to five years of loss runs (a report listing past claims), known incidents, and your current policy.

What affects the cost of $5M?

• What you inspect. Safety-critical parts usually cost more to insure than general receiving inspection.
• Release authority. Signing off on product often adds risk.
• How the $5M is built. Primary layers usually cost more per $1M of limit than excess layers.
• Claims history. Past claims can raise the price.
• Retention. This works like a deductible, and a higher one usually lowers premium.

Frequently asked questions

I carry $1M or $2M as a quality control firm. How do I get to $5M?

Request new quotes through Morrow, either a new $5M primary policy or excess layers over a primary. Morrow can ask carriers to keep your retroactive date and prior acts coverage (cover for past work done before the new policy starts) where the market allows. Report known incidents to your current carrier before you switch.

Do I need $5M Professional Liability as a quality control inspector?

You need it only if your contract, RFP or client says so. Check the clause for per claim and aggregate wording and whether excess layers count.

Is $3M enough if my contract says $5M?

Not if the clause says not less than $5M. A $3M limit falls short, so request quotes for a $5M structure, either one primary policy or a primary plus follow-form excess.

Can my OEM client be added as an additional insured on my Professional Liability?

Usually not. Additional insured status (listing the client as a covered party) is uncommon on Professional Liability. Many clients accept a certificate of insurance (a one-page proof of coverage) listing every layer. Confirm what your contract requires.
