What is class code 6306?
NCCI class code 6306 (Sewer Construction & Drivers) is used by workers' compensation insurance carriers to classify the work performed by your employees. Class codes determine the rate per $100 of payroll that you pay for coverage. Codes with higher injury risk (like roofing or tree care) have higher rates; clerical and office work has the lowest rates.
The construction industry typically falls in hazard group E (Moderate-high risk). Many businesses in this category are misclassified by previous carriers — if your current policy lists a different code, it's worth a free review to make sure you're not overpaying.
How premium is calculated for code 6306
Your premium for class code 6306 starts with your gross annual payroll for employees doing this type of work. Divide by 100, multiply by the state-approved rate (typically between $$7.00 and $$16.00 for this code), then multiply by your experience modification factor (mod). New businesses start with a 1.0 mod; after a few years your mod reflects your actual claims history.
