What are ISO Classification Codes?

ISO Classification Codes are standardized codes developed by the Insurance Services Office to classify businesses for insurance rating purposes.

Manufacturing and processing operations fall under the 50000 series codes, with specific sub-codes identifying your particular type of manufacturing operation.

Why it Matters for Manufacturers

Your ISO classification code directly impacts your insurance premiums because it determines how insurers assess your risk level. Being classified correctly ensures you are not overpaying for insurance or, conversely, being undercharged and potentially facing coverage issues later.

Different manufacturing operations (food processing vs. metal fabrication vs. chemical manufacturing) carry vastly different risk profiles. Understanding your classification helps you communicate accurately with insurers and brokers, ensuring proper coverage at appropriate rates. Misclassification can lead to denied claims or surprise premium adjustments.
