How the list is read
Entries are 2 or 4 digit NAICS codes, plus one range, 31-33 for Manufacturing. A 6-digit code falls under the entry it begins with: 238220 falls under 23, Construction, and 332311 under 31-33, Manufacturing.
The three groups that submit
| Establishment | Sends to the ITA | Paragraph |
|---|---|---|
| 20 to 249 employees, industry in Appendix A | Form 300A data | 29 CFR 1904.41(a)(1)(i) |
| 250 or more employees, required to keep Part 1904 records | Form 300A data | 29 CFR 1904.41(a)(1)(ii) |
| 100 or more employees, industry in Appendix B | Form 300 and 301 case data, in addition to Form 300A data | 29 CFR 1904.41(a)(2) |
Headcount means the most employees the establishment had at any time during the previous calendar year. An establishment in none of the three groups submits only if OSHA notifies it. State Plan states are covered: 29 CFR 1904.41(b)(7). The authority for a single establishment is OSHA's OSHA ITA Coverage Application.
At 100 or more employees, check Appendix B as well.

Open the converterShort answers
Is construction in Appendix A?
Yes. NAICS 23, Construction, is listed, so a construction establishment with 20 to 249 employees submits Form 300A data.
Does an establishment with fewer than 20 employees submit Form 300A data?
Not routinely. The three groups in 29 CFR 1904.41 start at 20 employees. OSHA can still notify an establishment to submit for an individual data collection.
Is the list based on the company or the establishment?
The establishment. OSHA's FAQ says the electronic reporting requirements are based on the industry classification of the establishment, not of the firm.
