Class Code 0040
Vineyards
Class Code 0040 (Vineyards) applies to field grape-growing operations in California — the hands-on vineyard work from pruning and canopy management to spraying and harvest. The September 1, 2026 approved pure premium rate for this class is $3.659 per $100 of payroll. Accurate classification and specific loss controls matter because vineyard operations carry seasonal, heat, pesticide, and equipment hazards that drive workers' comp costs.
What Class Code 0040 Covers
This classification covers outdoor vineyard field operations: vine pruning (spur and cane pruning), shoot thinning and canopy management, tying and trellising, fruit thinning, hand and mechanical harvesting, pesticide and fertilizer application in the vineyard, irrigation and drip-line installation and repair, and ordinary vineyard maintenance. It includes work done on vineyard rows, slopes and terraces, including use of tractors, mechanical harvesters and tractor-drawn sprayers. Office, tasting-room, bottling, fermentation or winery cellar work is not included under 0040 and should be reported under the appropriate manufacturing or office codes. The code applies whether labor is permanent, seasonal, piece-rate or contracted when the payroll relates to field grape-growing activities.
Who It Applies To
- Field vineyard laborers (pruners, harvest pickers, canopy workers)
- Vineyard foremen and field supervisors working in the rows
- Seasonal harvest crews and migrant laborers assigned to vineyard tasks
- Licensed pesticide applicators and handlers performing vineyard spray work
- Equipment operators (tractors, mechanical harvesters, sprayer drivers)
- Irrigation and trellis installation/repair crews working in vineyards
Common Job Duties
- Pruning vines by hand using pruning shears or knives
- Tying, training and repairing trellis systems and posts
- Canopy management: shoot thinning, leaf pulling, cluster thinning

- Installing, troubleshooting and repairing drip irrigation and hoses
- Operating tractors, PTO-driven equipment and vineyard sprayers
Common Injury Risks
Understanding the $3.659 Rate
The pure premium rate of $3.659 per $100 of payroll represents the expected loss cost for claims in this class and is the base used to calculate workers' comp premium. Insurers apply that pure premium to your payroll, then add expense loads, taxes, schedule credits/debits, and adjustments like experience modification, which together determine the final premium you pay. Employers can also affect premiums through loss-control programs, claims management, deductible or retrospective-rating options and correct payroll reporting.
Cal/OSHA Compliance Requirements
Vineyard employers must follow Cal/OSHA requirements most relevant to outdoor agriculture: implement and document Heat Illness Prevention measures (8 CCR 3395), provide required training and appropriate PPE for pesticide exposure, and comply with hazard communication and respirator rules when chemicals are used. Employers should maintain equipment guarding, train on safe tractor and PTO operation, enforce ladder safety, and follow EPA/California Department of Pesticide Regulation Worker Protection Standard requirements for pesticide handlers and field workers.
How Key HR Helps Employers Under Class Code 0040
A PEO like Key HR helps vineyard employers centralize payroll and ensure correct class coding and reporting for seasonal and piece-rate labor, which reduces audit risk. Key HR provides industry-specific loss-control resources — heat-illness plans, pesticide safety training, equipment safety programs — plus managed claims handling, return-to-work coordination and experience-mod monitoring to help lower workers' comp costs over time.

Does Class Code 0040 cover winery cellar or bottling work?
No. Class Code 0040 is specific to vineyard field operations. Winery cellar work, bottling, crushing and fermentation are different exposures and should be reported under the appropriate production or office class codes.
Are seasonal harvest crews and piece-rate pickers included in 0040?
Yes. Seasonal and piece-rate workers performing vineyard field duties are typically reported under Class 0040 for the payroll related to those duties. Administrative, driving or winery tasks performed by the same worker should be allocated to their correct class codes.
What practical steps lower workers' comp costs for vineyards?
Focus on heat-illness prevention, documented pesticide training and PPE, ergonomics for lifting/packing, regular equipment maintenance and operator training, and a formal return-to-work program. Partnering with a PEO for claims management, payroll accuracy and targeted loss-control visits further helps reduce premiums and experience-mod impact.
