Class code 5432 covers carpentry operations not otherwise classified where workers fall into the high-wage payroll band. The September 1, 2026 approved pure premium is $5.321 per $100 of payroll — a starting point employers use to estimate expected loss costs for on-site carpenters.
This classification applies to hands‑on carpentry work not specifically listed under another WCIRB code, performed by higher‑paid carpenters and crews. Typical operations include framing, finish and trim carpentry, on‑site cabinetry and casework installation, temporary formwork for concrete, and field layout and set‑up for building components. Because it is the “NOC” (not otherwise classified) high‑wage variant, it captures experienced journeymen, lead carpenters, and foremen who perform manual carpentry rather than purely administrative supervisors. It excludes purely clerical staff, specialty trades specifically coded elsewhere (for example, factory cabinet manufacturing under a woodworking code), and non‑carpentry trades on the same jobsite.
The pure premium of $5.321 per $100 of payroll represents the expected cost of losses for payroll assigned to class 5432 before insurer expense loads and adjustments. Insurers multiply that pure premium by your payroll in hundreds of dollars to get a loss cost, then add expense, profit, and apply your experience modification, any credits or debits, and policy options to determine the final premium.
Cal/OSHA requires a written Injury and Illness Prevention Program (IIPP) and enforces specific controls for carpentry trades: fall protection for elevated work, ladder and scaffold safety, respiratory protection when wood dust or chemical exposures occur, and heat illness prevention for outdoor crews. Employers must provide relevant training, PPE, hazard communication for adhesives/solvents, and maintain records and certifications for respirator and scaffold training where applicable.
A PEO like Key HR helps manage class 5432 exposure by ensuring correct payroll classification, administering workers' comp coverage, and providing proactive loss control: tailored safety programs, on‑site or remote training (fall protection, tool safety, respirator use), OSHA recordkeeping, and prompt claims handling to shorten indemnity and medical costs. We also pursue group rating, return‑to‑work programs, and claims management strategies that can lower your experience modification and final premium.
Get a QuoteYes. Workers who perform hands‑on carpentry duties, even if paid at a higher wage, are typically coded to the high‑wage NOC carpentry classification. Supervisors who perform little or no manual carpentry should be classified separately and not in 5432.
Implement a written IIPP, mandatory fall‑protection and ladder training, tool and nail gun safety, a return‑to‑work light‑duty program, and disciplined claims reporting. Accurate payroll allocation, regular safety audits, and participating in group rating or retrospective programs also reduce costs.
At minimum you need a written IIPP, fall protection procedures and training, ladder and scaffold safety training, heat illness prevention for outdoor work, and respirator and hazard communication programs where wood dust or chemicals are present. Keep documentation of training, fit tests, and program audits for inspections.
