Industries Using Hazmat in Tennessee
These industries drive Hazmat freight demand in Tennessee.
Chemical Manufacturing
Eastman Chemical's Kingsport complex is one of the largest chemical manufacturing sites in the US, producing performance chemicals, fibers, and plastics. Class 3 flammable, Class 6.1 toxic, and Class 8 corrosive products ship nationwide from this facility.
Nuclear Materials
Oak Ridge National Laboratory and the Y-12 National Security Complex generate Class 7 radioactive shipments. ORNL handles nuclear isotope production, spent fuel management, and research materials requiring specialized hazmat transport.
Fuel Distribution
Memphis petroleum terminals and Nashville pipeline terminals distribute fuel throughout Tennessee. Memphis also serves as a regional fuel redistribution hub for the Mid-South, with tanker trucks reaching into Mississippi, Arkansas, and western Kentucky.
Key Hazmat Freight Lanes in Tennessee
High-volume Hazmat lanes originating in or passing through Tennessee.

Tennessee Regulations for Hazmat Freight
Key regulatory considerations for Hazmat shipping in Tennessee.
Tennessee Hazmat Route Designations
TDOT designates I-440 as the hazmat bypass around Nashville and I-640 around Knoxville. Through-traffic hazmat is discouraged from downtown routes. Memphis uses I-240 as the hazmat bypass.
Smoky Mountain Restrictions
I-40 through the Smoky Mountains between Knoxville and Asheville, NC includes steep grades and a 6,000-foot elevation tunnel. While most hazmat is permitted, winter weather can close the route to hazmat vehicles, and TDOT escorts hazmat through congested tunnel construction zones.
Oak Ridge Security Corridor
Routes near Oak Ridge (Bethel Valley Road, Bear Creek Road) have security checkpoints. Class 7 radioactive shipments to/from Oak Ridge require DOE advance notification and may require security escorts. State Route 95 is the primary access road.
Market Insights: Hazmat in Tennessee
Central Hub
Tennessee's central Southeast location makes it a natural hazmat redistribution point. Carriers based in Nashville or Memphis can serve markets from Atlanta to St. Louis to Louisville within a half-day drive.
Eastman Anchor
Eastman Chemical's Kingsport complex alone generates hundreds of hazmat truck loads daily. Carriers who secure Eastman business have a stable, high-volume freight base in an otherwise rural part of the state.
Hazmat Shipping in Tennessee — FAQs
How significant is Eastman Chemical for Tennessee hazmat?
Eastman's Kingsport complex is one of the largest chemical manufacturing sites in the US. It generates hundreds of daily hazmat truck loads across multiple DOT classes, making it the single largest hazmat freight generator in the state and a critical anchor for eastern Tennessee carriers.
What nuclear materials move through Tennessee?
Oak Ridge National Laboratory produces medical and research isotopes (Class 7 radioactive), handles nuclear fuel management, and ships research materials to other DOE facilities. These shipments follow strict DOE protocols with advance state notification and security escorts.
Are there hazmat bypass routes around Tennessee cities?
Yes. Nashville uses I-440, Knoxville uses I-640, and Memphis uses I-240 as designated hazmat bypasses. Through-traffic hazmat carriers should use these routes to avoid downtown congestion and local restrictions.
