Class Code 8350
Gasoline Or Oil Dealers – Wholesale
Class Code 8350 covers wholesale gasoline and oil dealers in California — businesses that store, transport and deliver bulk petroleum products. The WCIRB pure premium for this class is $5.550 per $100 of payroll, which reflects the claim cost history for wholesale fuel distribution operations.
What Class Code 8350 Covers
This classification applies to businesses engaged in the wholesale distribution of gasoline, diesel, lubricants and other petroleum products rather than retail service stations. Typical operations include bulk terminals, inland bulk storage, loading and unloading tank trucks, delivery to commercial customers or service stations, and fleet-fueling services. Covered employees include tanker and bobtail drivers, terminal loaders/unloaders, tank maintenance crews, yard and warehouse personnel, and clerical staff who work at a wholesale fuel facility. The code does not usually apply to retail convenience store attendants who pump fuel directly to consumers; those workers are classified under retail/service-station codes. Employers should separate payroll by operation (wholesale loading/delivery versus retail pumping) so the correct classification is applied.

Common Injury Risks
Understanding the $5.550 Rate
The pure premium rate of $5.550 per $100 of payroll represents the WCIRB's estimated claim cost for this class before insurer adjustments. Insurers use the pure premium as the base to calculate an employer's premium, then apply factors such as the experience modification (E-mod), classification splits, scheduled credits/debits, policy deductible choices and state assessments to arrive at the final premium. Employer loss history, safety programs, payroll accuracy and job classification audits materially affect what you actually pay.
Cal/OSHA Compliance Requirements
Wholesale fuel operations must follow Cal/OSHA requirements for hazardous materials, including the Hazard Communication standard, flammable and combustible liquids handling and storage rules, and confined space entry procedures for tanks. Employers must provide training on vapor hazards, PPE, hot-work permits, lockout/tagout for equipment servicing, and emergency spill response. Wholesale operators should also coordinate with local CUPA requirements such as Hazardous Materials Business Plans (HMBP) and maintain spill prevention and countermeasure (SPCC) practices.
How Key HR Helps Employers Under Class Code 8350
A PEO like Key HR helps wholesale fuel dealers by ensuring correct payroll classification and documentation, implementing driver qualification and vehicle maintenance programs, and delivering tailored safety training (flammable liquids handling, confined-space entry, spill response). Key HR also manages workers' comp claims and return-to-work programs to shorten loss durations, which can lower your experience modification and overall premium cost.
Get a QuoteFrequently Asked Questions
Are retail gas station attendants included in Class Code 8350?
No. Class Code 8350 is for wholesale gasoline and oil dealers involved in bulk distribution and delivery. Retail station attendants who pump directly for consumers are typically classified under a retail/service-station code, so payroll should be split between wholesale and retail operations.
What practical steps can reduce my workers' comp costs under this class?
Focus on driver screening and training, preventive vehicle and hose maintenance, rigorous transfer and grounding procedures, documented spill response plans, PPE enforcement, and a fast, proactive claims and return-to-work program. These measures reduce claim frequency and severity and improve your experience modification.
Do tanker drivers need special endorsements or training beyond workers' comp requirements?
Yes. Drivers usually need a commercial driver’s license (CDL) with appropriate hazardous materials endorsements, DOT-required HazMat training, and employer-run qualification files. From a workplace-safety standpoint, employers must provide task-specific training on safe loading/unloading, grounding/bonding, and emergency procedures under Cal/OSHA.
