NAICS 486 - Pipeline Transportation

This page includes content generated by AI. It is intended for general guidance only and should be verified for your specific situation.

What is NAICS 486

NAICS code 486, Pipeline Transportation, covers industries engaged in the transmission of products such as crude oil, natural gas, refined petroleum products, and slurry through pipeline networks. These businesses operate extensive pipeline systems that serve as critical infrastructure for energy distribution and supply chain continuity. Pipeline transportation plays a vital role in moving large volumes of energy products efficiently and safely over long distances, often crossing state lines and international borders.

Companies in this sector specialize in designing, constructing, operating, and maintaining pipeline networks and related facilities, including storage where applicable. Given the strategic importance of energy resources, government agencies contract these services to ensure reliable energy supply, support emergency response capabilities, and maintain national energy security. The interconnected nature of pipeline networks demands rigorous compliance with safety, environmental, and operational standards, making government oversight and partnerships essential.

Industry Classification for NAICS 486

Industries in the Pipeline Transportation subsector use transmission pipelines to transport products, such as crude oil, natural gas, refined petroleum products, and slurry. Industries are identified based on the products transported (i.e., pipeline transportation of crude oil, natural gas, refined petroleum products, and other products).The Pipeline Transportation of Natural Gas industry includes the storage of natural gas because the storage is usually done by the pipeline establishment and because a pipeline is inherently a network in which all the nodes are interdependent.
