FedEx Corporation — Memphis Headquarters
FedEx Corporation is headquartered in Memphis, with the FedEx World Hub at Memphis International Airport (the company’s principal sorting facility, the largest cargo airport in North America). Per Tennessee Lookout reporting (August 2025), FedEx employs "more than 39,000 people in Tennessee." FedEx’s workforce includes:
- FedEx Express pilots: FAA-regulated, subject to 14 C.F.R. Part 120 and 49 C.F.R. Part 40 federal drug testing. Categorical cannabis prohibition.
- FedEx Express, Ground, and Freight CDL drivers: FMCSA-regulated under 49 C.F.R. Part 382. Categorical cannabis prohibition.
- FedEx mechanics, ramp agents, and ground operations workers: subject to FedEx’s own corporate drug-testing policies, which align with federal aviation and DOT standards even where not federally mandated.
- Corporate workforce: subject to FedEx’s general corporate drug-testing policies.
FMCSA Part 382 — CDL Drivers

- Post-accident.
- Return-to-duty.
- Follow-up.
Cannabis testing cutoff: 50 ng/mL (immunoassay) and 15 ng/mL (confirmation). DOT Drug and Alcohol Clearinghouse maintains positive-test records for 5 years; positive-test drivers cannot operate commercial motor vehicles in interstate commerce until completion of return-to-duty process. Tennessee hosts substantial trucking-and-logistics infrastructure (FedEx, U.S. Xpress, Covenant Logistics, J.B. Hunt, Pilot Flying J) with thousands of CDL drivers.

The Federal Schedule III Rescheduling Limit
The DOJ Schedule III rescheduling order published April 28, 2026 (91 Fed. Reg. 22714) does NOT change DOT 49 C.F.R. Part 40 testing rules: cannabis testing remains required for safety-sensitive transportation workers. FMCSA, FAA, FRA, USCG, and PHMSA testing regimes are unchanged. FedEx pilots, FedEx Express drivers, Nashville and Memphis airport workers, and Tennessee railroad workers remain categorically prohibited from cannabis use regardless of state-law or federal-rescheduling status.
