Hawaii Workers Compensation Class Codes: What Employers Need to Know

How Hawaii Workers Compensation Class Codes Work

Workers compensation class codes are three- or four-digit numbers that group jobs by the level of injury risk they carry. Hawaii uses its own version of the National Council on Compensation Insurance (NCCI) classification system, which means the codes and rating logic here can differ from what employers see in mainland states. Each code maps to a base premium rate, and your payroll for that class drives the final cost. In Hawaii, the Department of Labor and Industrial Relations (DLIR) oversees the workers compensation system, and the rating bureau adjusts class code assignments based on statistical injury data collected across the islands.

Because Hawaii's economy leans heavily on tourism, construction, and agriculture, certain class codes carry higher exposure than typical office roles. Rates reflect the historical claims experience of each classification within the state, so a construction firm in Honolulu may see a different premium profile than the same firm operating in a mainland metro.

Common Hawaii Class Codes by Industry

• 8742 — Clerical Office Employees: Low-risk, standard rate.
• 8810 — Salespersons, Office: Low-exposure, clerical rate.
• 5092 — Painters, Interior: Moderate risk, frequent claims.
• 8017 — Janitors and Cleaners: Higher risk due to slip-and-fall exposure.
• 5203 — Construction — Framing: High risk, significant premium.
• 0738 — Agriculture — Farm Workers: Variable risk depending on task.
• 7382 — Tourism — Hotel Housekeeping: Moderate risk, common in Hawaii.

What Happens When a Business Is Misclassified

Misclassification can cost employers significantly. If your workers are grouped under a code that understates their risk, Hawaii DLIR can reassess your premium during an audit and collect additional premiums plus interest. Conversely, overclassification inflates your payroll costs without real benefit. Common misclassification triggers include treating a supervisor as clerical when they regularly perform fieldwork, or coding construction helpers under a general labor code instead of the specific trade classification. Hawaii has its own audit procedures under state law, and carriers can reclassify codes retroactively within the statutory lookback period.

How to Verify Your Class Codes

Start with your workers compensation policy and the classification worksheet attached to it. Compare the listed codes against your actual job duties and the NCCI or Hawaii-specific codebook. If your payroll includes multiple roles, each distinct job function may need its own code. For businesses with mixed operations — for example, a tour company that also runs a maintenance crew — proper split-point allocation between class codes matters for accurate pricing. You can request a rating bureau advisory from your insurer or contact DLIR directly for guidance on contested classifications.

Hawaii-Specific Factors That Influence Rates

Hawaii's isolated geography and small labor pool create unique dynamics. Medical costs tend to run higher due to limited provider competition and geographic isolation, which feeds into the experience modification factor applied to each class code. Catastrophe exposure — hurricanes, volcanic activity — can also shape how carriers price certain construction and infrastructure codes. These geographic surcharges are layered on top of the base class code rate and vary by island and county.
