Changes Coming to Electronics, Dual-Wage Class Codes

Posted on: March 7th, 2024 by Leaders' Choice Staff No Comments

The Workers’ Compensation Insurance Rating Bureau of California will recommend changes to class codes for some electronics manufacturing sectors, as well as increases to the wage thresholds for construction industry dual classifications.

The move comes after the Rating Bureau’s governing committee unanimously approved proposed changes, which will be sent in March to the state insurance commissioner for approval. If approved, the changes will take effect Sept. 1, 2024. Here’s what’s on tap:


Electronics manufacturing industry

One of the proposed changes would link two more classes to the 8874 companion classification, which was created in September 2022 to cover certain low-risk classes in the electronics industry group.

Currently, 8874 is a companion class that covers payroll for lower-risk jobs in hardware and software design and development, computer-aided design, clerical and outside sales operations for two electronics industry classes — 3681 (manufacturing operations for electronic instruments, computer peripherals, telecommunications equipment) and 4112 (integrated circuit and semiconductor wafer manufacturing).

The new proposal would move to 8874 similar low-risk white-collar personnel currently assigned to class 3572 (medical instrument manufacturing) and 3682 (non-electric instrument manufacturing).

The Rating Bureau is also recommending merging class code 3070 (computer memory disk manufacturing) with 3681(2) (computer or computer peripheral equipment manufacturing).

If this recommendation is okayed, the higher pure premium rate of $0.46 per $100 of payroll for class code 3681 will apply to the new combined code. Class 3070 currently has a pure premium rate of $0.25 per $100 of payroll and the new rate would be phased in at 25% per year until class 3070 is eliminated and all employers are moved to class 3681.


Dual-wage increases

The Rating Bureau will also recommend increasing the thresholds that separate high- and low-wage earners in 16 dual-wage construction classes.

These class codes have vastly different pure premium rates for workers above and below a certain threshold as the lower-wage workers have historically filed more workers’ comp claims. Rates for lower-wage workers are often double the rates for higher-wage workers.

The following illustrates the changes:
