Yes you do. You’ll need comprehensive general liability coverage, more specifically, product liability. This coverage insures a business against accidents and injury that might happen on its premises, as well as exposures related to its products as long as it is not due to poor workmanship.
This points out one difficulty with general liability insurance: it tends to have a lot of exclusions. Make sure you understand exactly what your policy covers and what it doesn’t. You may want to purchase additional liability policies to cover specific concerns you might have about your product.
