Examples of how General Liability Class Codes are used:

A business consultant (ISO CGL Code 41677) is more vulnerable to errors that might harm a client’s revenues, whereas a carpenter (ISO CGL Code 91340) is more prone to the risk of personal injury.

Since each of these industries possesses different risk exposures, they need different types GL classifications. General Liability classifications categorize businesses according to the service they provide and the hazards and risks that are unique to those services.

When GL Class Codes are used for Exclusions:

While insurance companies use GL codes to approve and rate businesses, they are also used to deny certain coverages as well. An example of operations not covered is called an exclusion. Exclusions limit the insurance company’s liability for activities that fall outside of the insured’s classification. For example, if a residential carpenter (ISO CGL Code 91340) frames a residential house that is faulty and incurs damages, the business is covered. If however, they incur losses as a result of framing a building that exceeds three stories in height, the business is not covered because this is excluded from that particular GL code.
