SIC vs NAICS Compliance & Common Mismatches

Legacy SIC code 7389 classifies commercial operations based on primary end-product or service output under the 1987 federal framework. In contrast, modern 2022 NAICS codes group establishments based on production process inputs.

When submitting public disclosures to SEC EDGAR or determining OSHA workplace safety log recordkeeping exemptions (29 CFR Part 1904), rely strictly on the official OSHA 4-digit SIC classification rather than an automated commercial translation.

💡 Expert Guidance: SIC to NAICS Conversion

Common Compliance Mistake: Many contractors and B2B analysts confuse legacy 4-digit SIC codes like 7389 with modern 6-digit NAICS codes. Ensure that you use the correct active 2022 NAICS code (e.g. from the crosswalk below) when submitting representations on SAM.gov, as federal contracting officers only accept modern NAICS codes.
