What does NCCI class code 3577 cover?
Class code 3577 classifies employees performing Plastic Articles Manufacturing, also known as Plastic Product Mfg, Plastic Molding. The NCCI classification system groups occupations by similar workplace exposure, loss-experience patterns, and operational characteristics. Code 3577 falls within the manufacturing industry group and is filed in California.
NCCI's governing classification rules state that a single-classification employer with at least 51% of payroll in this occupation generally classifies all employees under code 3577, with two standard exceptions: clerical office work (segregated payroll records required, reported under code 8810) and outside sales / collectors (code 8742). If your operation has multiple distinct activities, ask your underwriter about a multi-class split before accepting a single-code rating.
Why code 3577 only appears in California
Some class codes are state-specials: classifications a single rating bureau maintains for an occupation that other states fold into broader codes. Code 3577 currently has a filed rate only in California ($0.950 per $100 payroll). If you operate in another state, your insurer will classify the same work under a different code, use the class-code finder to locate the equivalent for your state.
How to use this code 3577 rate data
- Identify the right state filing. Use the table below to find your state's filed rate. If your carrier is quoting at a higher rate, the difference is either schedule debit, EMR, deductible loading, or a state-fund surcharge, ask which.
- Calculate your effective rate. Effective rate = base rate × EMR ± schedule credit/debit ± deductible loading. Two carriers quoting code 3577 at the same base can vary 30%+ on effective rate after these adjustments.
- Build a 3-year EMR strategy. A 0.85 EMR cuts base rate by 15%; the difference between 0.85 and 1.25 EMR on the same code is a 47% premium difference. Frequency control (preventing every claim, even small ones) drives EMR more than severity control.

What types of claims drive code 3577 rates?
Workers comp rate filings for code 3577 reflect what's actually happening on the job, not just generic occupation hazard. NCCI publishes loss-cost analyses showing which injury categories account for the bulk of indemnity (lost-wage) and medical claim cost. For Plastic Articles Manufacturing, the top drivers are typically:
- Caught-in machinery from lockout/tagout failures, high severity per claim, drives rate spikes when present.
- Repetitive motion injuries, carpal tunnel and tendinitis from production-line work, dominate claim frequency.
- Material handling strains, lifting, twisting, pushing-pulling, are pervasive across all manufacturing codes.
- Chemical exposure, when applicable, produces both acute and long-latency claims.
Targeting these drivers in your safety program produces the largest EMR improvement. Frequency control (preventing every claim, including small medical-only incidents) drives the modifier more than severity control. A documented written safety program addressing the top two drivers above is typically the highest-ROI intervention for employers paying for code 3577.
