September 1, 2026 California Class Code Changes – WCIRB Webinar
I decided to view this WCIRB webinar on the Class Code Changes that went into effect this month. This one was a little more on the technical side than the previous article on NCCI reclassification of class codes. Instead of directly quoting from the webinar, I decided to include the two handouts that you can find here.
Whenever the presentation becomes available on WCIRB’s website, I will update this article with a link. At the end of this article, the handout can be downloaded. I recommend it for a quick review of the subjects presented today.
Join us for our annual review of updates to the California Workers’ Compensation Uniform Statistical Reporting Plan—1995 (USRP). This practical session will explain what changed, why it changed, and what you should watch for when these classifications arise in real-world situations.

Whether you work in underwriting, auditing, classification, agency operations, or policy administration, you’ll leave with a clearer understanding of the changes effective September 1, 2026.
Topics included:
- Results of the WCIRB’s Food and Beverage Manufacturing or Processing Industry review – The food processing industry is a huge part of CA’s economy. If you own or have any dealings with the food processing industry, such as Canning, make sure to check out that section of the handout below and the presentation when the WCIRB uploads it to their webinar page.
- Elimination of Classification 3070, Computer Memory Disk Manufacturing – rigid
- Clarifications to Classification 9015(1), Building Operation – N.O.C. – all other employees – including resident employees
