SC Major Employers — BMW, Boeing 787, Michelin Drug-Testing Regimes

Last verified: May 2026

BMW Manufacturing — Spartanburg County

BMW Manufacturing Co., LLC, headquartered in Greer (Spartanburg County), operates the largest BMW plant in the world by output and is the largest U.S. automotive exporter by value with $10.1 billion in export value in 2024 (per BMW Manufacturing’s official press release citing U.S. Department of Commerce data). The plant produces the X3, X4, X5, X6, X7, and XM crossovers and assembles roughly 400,000 vehicles per year.

BMW conducts pre-employment, random, and post-accident testing on hair-follicle and urine samples. The hair-follicle modality has a ~90-day detection window for cannabis metabolites — substantially longer than the urine 30-day max for heavy users — and is widely understood in the SC labor market as a comparatively strict screen. The South Carolina Supreme Court has held in BMW-context litigation that independent labs conducting drug tests owe a duty of care to tested employees, providing a narrow defense against negligent-testing false positives but not against confirmed positives.

Boeing South Carolina — North Charleston, 787 Final Assembly

Boeing South Carolina, in North Charleston, is the principal final-assembly site for the 787 Dreamliner. Boeing applies its enterprise-wide Drug and Alcohol Free Workplace Program across all locations, with testing per DOT and Boeing internal policy. Boeing operates as a federal contractor (USAF, USN, FAA), making the federal Drug-Free Workplace Act of 1988 (41 USC § 8101) and Executive Order 12564 binding on the workforce regardless of any future SC state-law cannabis policy.

Boeing 787 production roles include FAA-regulated airframe-and-powerplant (A&P) mechanic positions, which are categorically subject to FAA Part 121 / Part 145 drug-testing requirements. Cannabis use — even off-duty, even in a state with comprehensive medical or adult-use programs — results in license action.

Michelin North America — Greenville

Michelin North America is headquartered in Greenville and operates several SC manufacturing facilities. Michelin maintains a drug-tested workforce; THC-positive tests have been a continuing termination basis. SC tire-manufacturing and distribution operations include FAA-regulated, OSHA-regulated, and DOT-regulated functions. The Greenville-based corporate workforce provides substantial professional employment with standard drug-testing protocols.

Volvo Cars — Berkeley County

Volvo Cars USA operates a manufacturing facility in Berkeley County (Ridgeville), producing the EX90, S60, and Polestar 3. Standard drug-testing regime applies: pre-employment, random, post-accident.

Mercedes-Benz Vans — Ladson

Mercedes-Benz Vans, LLC operates a Sprinter and Metris assembly facility in Ladson (Charleston County). Standard drug-testing regime; pre-employment screening universal for production and skilled-trade roles.

Honda of South Carolina — Florence

Honda of South Carolina Mfg., Inc. in Florence produces all-terrain vehicles (ATVs) and personal watercraft (PWC). The plant is one of the largest employers in the Pee Dee region and operates standard drug-testing protocols.

Bosch & the Upstate Automotive Supplier Cluster

Beyond the OEM plants, the Upstate hosts a dense automotive-supplier cluster including Bosch, ZF, Magna, Continental, and dozens of Tier 1 / Tier 2 suppliers. The cluster employs tens of thousands across Spartanburg, Greenville, Anderson, and Cherokee counties. Drug-testing regimes are standard across the cluster, often driven by OEM-customer requirements.

GE & Other Industrial Manufacturers

Greenville hosts GE Power gas-turbine manufacturing. Industrial manufacturing across the state — aerospace, energy, chemical, paper, food — uniformly maintains drug-testing protocols, both because of federal-contractor exposure and because of SC’s drug-free workplace 5% workers’ comp discount under § 38-73-500.

Healthcare Sector

Major SC healthcare employers — Prisma Health (the state’s largest healthcare system, headquartered in Greenville and Columbia), MUSC Health (Charleston), Roper St. Francis (Charleston), and the various regional hospital systems — conduct pre-employment and reasonable-suspicion testing. Healthcare employees in DEA-regulated roles (pharmacy, controlled-substances handling, diversion-control positions) face federal-policy constraints independent of state law. A positive cannabis test typically results in immediate suspension of access to controlled-substances functions.

Tourism and Hospitality — Inconsistent Application

Major resort operators — Hilton Head’s Sea Pines Resort and Palmetto Dunes; Kiawah Island; the Grand Strand resorts in Myrtle Beach — test for safety-sensitive roles (lifeguards, golf-course operations, food-service supervisors) but inconsistently for line staff. Industry observers note that on-duty workplace cannabis use is broadly understood to be common in the SC hospitality sector despite formal drug-test policies; the policy contradiction is well-known but not formally addressed. Tourism contributes ~$29 billion annually to the SC economy, with Charleston, Myrtle Beach, and Hilton Head as the principal anchors.

Federal Contractor and Defense-Industrial Employers

Beyond Boeing 787, SC has a substantial federal-contractor and defense-industrial workforce: SAIC, Booz Allen, Raytheon, Lockheed Martin, BAE Systems, and dozens of smaller contractors operate from Charleston-area, Columbia-area, and Greenville-area locations. Federal-contractor cannabis prohibition under the Drug-Free Workplace Act of 1988 applies across the cluster. See federal installations page.

Walmart and Big-Box Retail — National Policy Variation

Walmart Inc. announced a national reduction in cannabis pre-employment screening for non-safety-sensitive roles in 2022, but Walmart’s SC store-level practice has been variable. Some SC managers continue testing; others follow the national reduced-screening posture. Other big-box retailers — Target, Costco, Home Depot, Lowe’s — have similar national policies with variable SC application.

What This Means for the SC Labor Market

• Recreational cannabis use is incompatible with employment in SC’s major manufacturing, federal-contractor, healthcare, and DOT-regulated employment categories. Hair-follicle testing has a ~90-day detection window.
• Out-of-state medical cannabis use is also incompatible. SC employers do not honor out-of-state medical cards, and even if the Compassionate Care Act becomes law, the most recent draft does not include categorical employment protection.
• Workers’ compensation benefits may be reduced or denied for an injury where a post-accident drug test reflects cannabis use, even if the use was off-duty and legally purchased in another state.
• Hospitality and service-sector employment has more practical tolerance, but no statutory protection.

How a Future Compassionate Care Act Might Interact

Sen. Davis’s S.53 (2025-26) would categorically exclude patients in public safety, commercial transportation, or roles operating heavy machinery. The bill is silent on workplace cannabis testing for non-excluded patients. If S.53 becomes law — not in the 2025-26 session, perhaps in a 2027 or later session — SC employers would retain broad latitude to test and terminate medical-cannabis patients, except where the bill’s eligibility-exclusion language operates as a categorical employment ban. The most likely market effect is that SC employers would continue current practice; the bill is structured to minimize workplace disruption rather than to create employee protection.
