What is the difference between a manufacturer and a contract manufacturer?

A "manufacturer" in pharmaceutical and medical device terminology typically refers to the entity that holds the product regulatory authorization (the New Drug Application, Biologics License Application, 510(k) clearance, or PMA approval) and brings the product to market under its own label. A "contract manufacturer" produces the product on behalf of the authorization holder under a contractual arrangement, without owning the marketing authorization itself.

The distinction matters for insurance because liability flows along the regulatory chain. The authorization holder (sponsor) is the principal regulatory respondent to FDA and the primary defendant in product liability litigation. The contract manufacturer is typically named as a co-defendant when manufacturing defects are alleged, but the indemnity architecture of the MSA usually shifts substantial liability between the parties.

For the contract manufacturer's insurance program, this means the products liability tower must respond not only to direct claims but also to contractual indemnity obligations owed to the sponsor under the MSA. Most contract manufacturers discover at first MSA review that their existing program covers direct liability but not the contractually assumed sponsor indemnity, which is a coverage gap requiring an insured contract endorsement or contractual liability extension.
