Running a plastic manufacturing operation means managing constant motion—machines cycling, employees handling materials, and production targets that leave little room for downtime. Whether you’re running injection molding, extrusion lines, or trimming operations, the reality is the same: your people are your most valuable asset, and they’re exposed to real risk every day.
At Wexford Insurance, we’ve worked closely with plastic manufacturing business owners who thought their safety protocols were airtight—until a repetitive strain injury, burn incident, or machine-related accident triggered a workers’ compensation claim. That’s why understanding workers’ compensation insurance for a plastic manufacturing business—especially its cost—is critical to protecting both your team and your bottom line.
Nate Jones, CPCU, ARM, CLCS, AU, founder of Wexford Insurance, explains it this way:
“Manufacturing risk isn’t just about catastrophic accidents—it’s the daily wear-and-tear injuries that quietly drive claims frequency. Workers’ comp pricing reflects that reality.”
In this guide, we’ll break down real-world cost expectations, what drives pricing, and how to control it without compromising protection.
Average Cost of Workers’ Compensation for Plastic Manufacturing
Workers’ compensation insurance is typically priced based on payroll and job classification codes assigned to your employees.
Here are realistic estimated ranges for plastic manufacturing businesses:
Estimated rate: $2.50 to $8.00 per $100 of payroll
Low-risk operations (automated or minimal manual handling): lower end
Standard manufacturing environments: mid-range
High-risk environments (heavy manual labor, complex machinery): higher end
Typical annual premium ranges:
Small operation: $3,000 – $8,000
Mid-sized manufacturer: $8,000 – $20,000+
Larger or high-risk facilities: $20,000+
These are estimates. Your actual cost depends heavily on your workforce, safety track record, and operational setup.
Estimated range: $1,000 – $6,000+ annually
Based on operations, product exposure, and claims history
Covers third-party injury and property damage claims tied to your operations.
Estimated range: $2,000 – $15,000+ annually
Driven by building value, equipment cost, and fire exposure
Protects your facility, machinery, and contents from covered events like fire, vandalism, and storms.
Estimated range: $3,000 – $12,000+ annually
Combines property and general liability into one package
Often cost-effective for smaller to mid-sized manufacturing operations.
Umbrella Insurance
Estimated range: $1,000 – $5,000+ annually
Provides additional liability coverage above standard limits
At Wexford, we often recommend umbrella coverage for manufacturers due to the severity potential of claims involving injuries or defective components.
What Influences Workers’ Compensation Costs
Workers’ comp pricing isn’t random—it’s based on how insurance carriers assess your risk.
Payroll Size
The more employees you have, the higher your exposure to injury claims. Payroll directly drives premium calculations.
Job Roles and Classification Codes
Not all employees are rated the same.
For example:
Machine operators typically carry higher rates
Administrative staff are rated lower
Maintenance or repair workers may fall somewhere in between
Accurate classification is critical to avoid overpaying or unexpected audit adjustments.
Claims History
Past claims influence your experience modification factor (mod), which can significantly impact your premium.
At Wexford, we’ve seen manufacturers reduce costs over time by improving safety and managing claims proactively.
Equipment and Operations
The types of machines you operate matter.
Plastic manufacturing often involves:
Injection molding machines
Heated materials
Mechanical presses
Cutting and trimming equipment
These factors increase injury risk and, in turn, insurance cost.
Safety Programs
Structured safety programs can reduce claims frequency and improve long-term pricing.
Nate Jones, CPCU, ARM, CLCS, AU, often advises:
“Insurance carriers reward consistency. A documented, enforceable safety culture is one of the fastest ways to improve your long-term workers’ comp position.”
What Workers’ Compensation Covers
Workers’ compensation insurance is designed to protect both your employees and your business when injuries occur on the job.
Medical Expenses
Covers:
Emergency care
Surgeries
Doctor visits
Prescriptions
Ongoing treatment and rehabilitation
Lost Wages
If an injured employee cannot work, workers’ comp provides partial income replacement during recovery.
Rehabilitation and Return-to-Work Support
Covers:
Physical therapy
Occupational therapy
Modified duty programs
Helping employees return to work safely can also reduce claim costs.
Employer Liability Protection
Provides protection if an employee files a lawsuit related to a workplace injury outside the standard workers’ comp system.
At Wexford, one of the most common claims we see in plastic manufacturing involves repetitive motion injuries—especially with trimming, assembly, and packaging tasks. These claims may not seem severe at first, but they can lead to extended time off work and ongoing medical treatment.
What a Complete Insurance Program Looks Like
Workers’ compensation is just one piece of your overall protection strategy.
General Liability Insurance
Protects your business against third-party injury or property damage.

Commercial Property Insurance
Protects your building, inventory, and machinery.
Commercial Auto Insurance
Covers vehicles used to transport materials, products, or employees.
Equipment and Inland Marine Coverage
Protects mobile equipment, molds, and specialized tools used in production.
Umbrella Insurance
Adds additional protection above standard limits, especially important for high-exposure manufacturing risks.
At Wexford Insurance we recently helped a plastic manufacturer restructure their insurance program after experiencing multiple small claims tied to repetitive tasks. By adjusting classifications, improving safety protocols, and layering coverage properly, they were able to stabilize premiums and reduce long-term risk exposure.
How to Lower Your Workers’ Compensation Costs
Implement formal safety training and enforce procedures consistently
Conduct regular equipment inspections and maintenance
Rotate employees to reduce repetitive strain injuries
Create a documented return-to-work program
Accurately classify employees to avoid overpayment
Investigate and address near-miss incidents
Work with an experienced independent agent to review your program annually
One of the most common mistakes Nate Jones, CPCU, ARM, CLCS, AU sees plastic manufacturers make is assuming safety improvements won’t impact insurance pricing.
“Every improvement compounds over time,” Nate explains. “Carriers look at trends, not just isolated changes.”
Important Compliance and Risk Considerations
Workers’ compensation requirements are governed by state law, but broadly speaking, most businesses with employees are required to carry coverage.
The Occupational Safety and Health Administration (OSHA) provides standards for workplace safety that directly influence risk exposure. Learn more: https://www.osha.gov
Additionally, the National Institute for Occupational Safety and Health (NIOSH) offers guidance on preventing manufacturing injuries, especially repetitive motion and machinery-related risks. Learn more: https://www.cdc.gov/niosh
Following these standards doesn’t just reduce injuries—it can directly influence your insurance profile over time.
Frequently Asked Questions
Is workers’ compensation required for plastic manufacturing businesses?
Yes, in most cases, once you have employees, workers’ compensation coverage is required. Specific rules vary, but operating without it can result in penalties.
Can I reduce my workers’ comp premiums over time?
Yes. Improving safety programs, maintaining a clean claims history, and managing injuries efficiently can lower your rates.
Does workers’ comp cover all injuries?
It covers most work-related injuries and illnesses but does not apply to injuries that occur outside of job duties.
Is workers’ compensation part of general liability insurance?
No. Workers’ compensation is a separate policy that specifically addresses employee injuries.
What is the biggest cost driver in workers’ comp for manufacturers?
In Nate Jones’s experience, frequency of smaller claims—especially repetitive injuries—has the biggest long-term impact on pricing.
