What Makes Delaware's Class Codes Unique
Delaware's workers' compensation class codes differ from other states by grouping occupations into 45 categories that directly influence premium calculations and claim handling. Each code reflects job risk, average wages, and injury frequency, ensuring premiums match actual workplace hazards.

How Class Codes Are Assigned
Employers submit payroll information and job descriptions to the Delaware Workers' Compensation Division. The division matches each employee's duties to a specific code, such as 251 for "Construction – General Labor" or 321 for "Office – Administrative."
Key Factors in Assignment
- Primary job duties
- Wage level
- Historical injury data for the occupation
Premium Impact of Class Codes
Premium rates vary by code, ranging from low‑risk codes (e.g., 410) to high‑risk codes (e.g., 251). An employer's overall premium is a weighted average based on the number of employees in each class and their respective wages.
| Class Code | Typical Occupation | Risk Level |
|---|---|---|
| 251 | Construction Labor | High |
| 321 | Administrative Staff | Low |
| 410 | Data Entry | Very Low |
Common Misconceptions
Some businesses assume a single code applies to all employees. In Delaware, each role—especially in mixed‑task environments—must be evaluated separately to avoid under‑or over‑pricing.
Maintaining Accurate Classifications
Regular audits of job descriptions and payroll records help keep class assignments current. Updating classifications after role changes or new hires prevents premium penalties and ensures compliance with state regulations.
