Top Industries in Butler County and Workers' Comp Rates
Workers' comp rates are set statewide by the PCRB based on class code — the same loss costs apply throughout Pennsylvania. Below are the most common industries in Butler County and links to industry-specific rate guides.
How Workers' Comp Rates Work in Butler County
Pennsylvania workers' compensation premiums are calculated using the same statewide formula regardless of where your business is located:
× 1.0218 (PA Act 57 assessment)
- PCRB Loss Cost — the actuarial base rate per $100 payroll, set by the PA Compensation Rating Bureau based on statewide claims history for your class code.
- LCM (Loss Cost Multiplier) — each carrier files their own multiplier (typically 1.20–1.80). Shopping carriers is the fastest way to reduce your premium.
- EMR (Experience Modifier) — your individual loss history score. Businesses with few claims have EMRs below 1.00; businesses with high claims pay more.

Workers' Comp FAQ — Butler County Employers
Butler County employers who have been insured with the same carrier for three or more years should request a market analysis. Pittsburgh's competitive market means significant premium savings are often available — particularly for clean-loss manufacturers and healthcare employers who may have been auto-renewed without a competitive shop.
How are Butler County plastics manufacturers classified for workers' comp?
Plastics manufacturing falls under codes in the 4400s range, with specific codes depending on the process (injection molding, extrusion, etc.). Light plastics fabrication typically carries moderate loss costs, while chemical and solvent-intensive processes can carry higher rates.
Does Butler County have a competitive workers' comp market?
Yes. Butler County employers benefit from Pittsburgh's highly competitive workers' comp market, with multiple carriers actively writing manufacturing, healthcare, and retail risks. Shopping multiple carriers — ideally through an independent broker with access to the Pittsburgh surplus and specialty markets — typically yields meaningful premium competition.
Are Butler County construction workers covered during off-season layoffs?
Workers' comp only covers injuries that occur during employment. Off-season layoffs are not covered periods — no wages, no workers' comp. However, if a worker is injured on a return-to-work call or during any compensated activity, coverage applies immediately.
Can a Butler County employer reduce their experience modifier?
Yes. The modifier is calculated by the PCRB based on claims data from the three prior policy years (excluding the most recent). Reducing claim frequency and severity over those years will lower your modifier. Implementing safety programs, return-to-work policies, and proactive claims management are the most effective strategies.
