Filed Figures for Class Code 3365 in the States That Publish Them
Copied from each state's own regulator or rating bureau filing, per $100 of payroll. A loss cost is what the filing calls it — your insurer multiplies it by its own loss cost multiplier; a rate is a manual rate. States not listed publish no per-class figure this site has transcribed.
Judged only from filed tables, code 3365 has a class percentile of 67 (0 = the cheapest class, 100 = the most expensive) across the 2 filings that list it.
How States Rank for Class Code 3365
Cost index 1.00 = the median of the 47 rated states. It is a relative position from this site’s model, not a price, and it does not vary by class code; a state’s filed figure, where it publishes one, is shown beside it. North Dakota, Ohio, Washington and Wyoming are not included. Each is a monopolistic state fund that sets premium on its own basis rather than on an NCCI class-code rate per $100 of payroll, so there is no comparable figure to average or rank.

About Class Code 3365: Scope, Inclusions, and Common Misclassifications
NCCI Class Code 3365 — "Welding or Cutting NOC & Drivers" — is the catch-all classification for contract welding and cutting operations that are not otherwise classified. It applies to specialist welding contractors who hire out to do arc, MIG, TIG, and oxy-fuel welding and cutting, whether in their own shop or in the field at a customer's site, and it includes the drivers who transport crews and equipment. 3365 is hazard group E, reflecting burn, fume, fire, and pressure-vessel exposure, so it carries a substantially higher base rate than light-manufacturing or clerical codes.
The key word is NOC — Not Otherwise Classified. 3365 is a residual code: it picks up standalone contract welding only when the welding is not already part of an operation that has its own classification. Welding done as a step within structural-steel erection, machine-shop work, plumbing, or auto repair stays inside that governing code rather than being split out to 3365. This page shows filed 3365 figures for the states that publish them and ranks the other states with a relative cost index, so a welding or fabrication contractor can see where its state sits before requesting a quote, and explains where the boundary falls.
What's Included Under Class Code 3365
3365 contemplates all types of contract welding or cutting performed by a specialist contractor that are not assigned to a more specific code. It covers both shop work and outside/field work, and the NCCI scope treats incidental machining performed in connection with the welding as part of the classification. Drivers transporting the welding crew and equipment to job sites are included, which is why the title ends in "& Drivers." Typical 3365 operations include mobile welding rigs, repair welding, custom metal fabrication that is sold as a welding service, and field cutting or torching.
Like other contractor codes, 3365 is duties-driven and assigned from the operations actually performed during the policy year, not from a business name. Because certain projects where welding is performed are extra-hazardous, NCCI's phraseology sets out operations that must be separately rated rather than folded into 3365 — for example welding inside tanks, on bridges, or as part of a higher-hazard erection or demolition job can carry its own classification. A welding contractor whose work spans several project types should keep payroll separated by job so the higher-hazard exposures are rated correctly.
When Welding Is NOT Coded 3365
3365 is a residual classification, so the most common audit dispute is whether welding should be split out at all. Under NCCI's governing-classification rules, welding that is an integral part of another classified operation generally stays in that operation's code. A structural-steel erection contractor whose ironworkers weld connections is rated under the steel-erection code, not 3365; a machine shop's welding stays in the machine-shop code; welding incidental to plumbing rates with the plumbing code 5183; and welding inside an auto-repair shop rates with the auto-service code. 3365 applies when welding or cutting is the contractor's standalone service sold to customers and is not otherwise classified.
Independent-bureau states matter for 3365. California (WCIRB), Pennsylvania (PCRB), Delaware (DCRB), New Jersey (NJCRIB), Michigan (CAOM), and North Carolina (NCRB) operate their own rating bureaus and may use different welding phraseology, code numbers, or separation rules than NCCI's 3365 — California in particular does not use the national 3365 number, so a California welding contractor should check WCIRB's classification search instead of relying on a national comparison.
Audit Records for 3365 Welding Contractors
The audit file that protects a 3365 assignment shows that the welding was a standalone contract service rather than a step inside another classified operation, and it separates any extra-hazardous welding exposures that must be rated under their own codes. Keep contracts, job logs, and payroll detail tied to each project type. Auditors decide 3365 versus the governing classification of a larger project from what the crew actually did on each job, not from the contractor's license category.
For quote shoppers, the figures on this page — filed figures from the states that publish them and a relative cost index for the rest — are a benchmark, not a binding quote. The final premium still changes with payroll, the carrier's loss-cost multiplier, experience modification, schedule credits, minimum premium, and any reclassification to a project-specific or state-specific welding code.

Frequently Asked Questions
- What is workers' comp class code 3365?
- Class code 3365 is "Welding or Cutting NOC & Drivers" — the NCCI catch-all for contract welding and cutting operations not assigned to a more specific code. It covers specialist welding contractors doing arc, MIG, TIG, and oxy-fuel welding and cutting in the shop or in the field, plus incidental machining and the drivers who transport the crew. It is hazard group E and carries a relatively high base rate because of burn, fume, and fire exposure.
- How much is workers' comp insurance for class code 3365?
- It depends on the state, and only some states publish a per-class figure. For class code 3365, the filed figures per $100 of payroll are: New York $2.725 (loss cost, NYCIRB, effective 2026-10-01); Wisconsin $3.061 (rate, WCRB, effective 2026-10-01). A loss cost is not a rate — your insurer multiplies it by its own loss cost multiplier — and every figure is before your experience modification. For other states this site shows a relative cost index, not a dollar figure. North Dakota, Ohio, Washington and Wyoming are not included. Each is a monopolistic state fund that sets premium on its own basis rather than on an NCCI class-code rate per $100 of payroll, so there is no comparable figure to average or rank.
- What businesses use workers' comp class code 3365?
- Class code 3365 typically applies to Welding shops, Fabrication shops, Pipeline welding firms, Structural welders, Custom metal fabricators.
- When is welding not classified under 3365?
- 3365 is a Not Otherwise Classified code, so it applies only to standalone contract welding. Welding that is part of another classified operation stays in that operation's code: ironworkers welding connections during structural-steel erection rate to the steel-erection code, a machine shop's welding stays in the machine-shop code, and welding incidental to plumbing or auto repair rates with those codes. 3365 is used when welding or cutting is the contractor's own service and is not otherwise classified.
- Does class code 3365 include drivers?
- Yes. The full title is "Welding or Cutting NOC & Drivers," so the drivers who transport the welding crew and equipment to and from job sites are included in the 3365 classification rather than split to a separate drivers code. Extra-hazardous welding projects, however, may have to be separately rated under their own classifications per NCCI's scope language.
