Class Code 5437
Workers Comp (NCCI)Carpentry — Cabinet Work / Interior Trim Installation
Finish carpentry: installing cabinets, interior trim, doors, and millwork. Meaningfully cheaper than framing codes because the work is interior and at floor level.
Operations commonly included
- Cabinet installation
- Interior trim, doors, and millwork
- Closet systems and built-ins
Commonly classified elsewhere
- Framing (5645/5403)
- Countertop fabrication (shop codes)
- Flooring installation (5478)
Real-world example
A two-person crew installing cabinets and trim in finished homes is 5437 — until the week they frame a garage, which belongs in 5645.
⚠️ Common audit mistake Letting occasional framing ride under 5437. Small hour counts still reclassify — track it separately.
State variation: Generally consistent in NCCI states; bureau states use equivalents.
Rated on: Gross payroll, per $100.
