OSHA's retail exemption excludes facilities that sell highly hazardous chemicals at retail from PSM coverage, even if threshold quantities are present. But the exemption is narrower than many employers assume. OSHA interprets "retail" based on the primary business activity and the nature of the customer. A distributor that supplies other businesses is not retail. A propane distribution company, a chemical reseller, or a wholesale operation will generally not qualify. OSHA has clarified in multiple letters that a mixed-use facility must evaluate each process independently — the retail label on the front door does not exempt warehousing or distribution operations in the back. These letters are the primary guidance for facilities on the margin.

⚡ Key Compliance Takeaway

The retail exemption turns on your customers, not your signage. If you sell to businesses, contractors, or industrial users, evaluate each process independently. A single non-retail sale does not automatically disqualify you, but a primary wholesale operation almost certainly does.
