What does NCCI class code 4814 cover?
Class code 4814 classifies employees performing Plastic Fabrication, also known as Plastic assembly, Custom plastic parts. The NCCI classification system groups occupations by similar workplace exposure, loss-experience patterns, and operational characteristics. Code 4814 falls within the manufacturing industry group and is filed in Washington.
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 4814, 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 4814 only appears in Washington
Some class codes are state-specials: classifications a single rating bureau maintains for an occupation that other states fold into broader codes. Code 4814 currently has a filed rate only in Washington ($0.468 per $100 payroll).

How to use this code 4814 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 4814 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 4814 rates?
Workers comp rate filings for code 4814 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 Fabrication, 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 4814.
