Petroleum Lubricating Oil and Grease Manufacturing
NAICS 324191 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in blending or compounding refined petroleum to make lubricating oils and greases and/or re-refining used petroleum lubricating oils.
Start the review with environmental/pollution liability.
For Petroleum Lubricating Oil and Grease Manufacturing, the saved research highlights environmental/pollution liability, fire and explosion, products liability. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What is the total bulk storage capacity on-site, and are tanks above-ground or underground?
- Does the operation include re-refining of used oil, and if so, what are the sources and volumes of used oil accepted?
- What pollution controls and secondary containment systems are in place, and when were they last inspected?
- Has the facility had any prior pollution incidents, regulatory notices of violation, or environmental agency contacts?
- What are the primary end-use markets for finished products — industrial, automotive, marine, or other?
- Are there owned vehicles used for product delivery or used-oil collection, and does the operation carry pollution coverage for transit?
- For Petroleum Lubricating Oil and Grease Manufacturing, what should the underwriter know about prior pollution incidents, regulatory enforcement actions, or superfund involvement at the site?
- For Petroleum Lubricating Oil and Grease Manufacturing, what should the underwriter know about bulk storage capacity above thresholds that trigger additional regulatory oversight, such as spcc or state petroleum storage programs?

Establishments in this class blend or compound refined petroleum products — such as base oils, additives, and viscosity modifiers — to produce finished lubricating oils, greases, and related products. Some operations also re-refine used petroleum lubricating oils, involving collection, processing, and reconditioning of spent lubricants. Day-to-day activities typically include bulk receiving and storage of petroleum feedstocks, blending and mixing in batch or continuous processes, quality testing, packaging, and outbound distribution to industrial, commercial, or retail customers.
