What drug testing regulations apply to maritime employers?

Maritime employers are subject to both USCG regulations under 46 CFR Part 16 for vessel crewmembers and DOT procedures under 49 CFR Part 40. Crewmembers holding a Merchant Mariner Credential (MMC) must be in a compliant testing program. Do It Right Screening manages full compliance under both regulatory frameworks.

What background screening do maritime companies need?

Maritime background screening needs vary by role and vessel type. At minimum, USCG-compliant drug testing and criminal background checks are required. Port facility workers may have additional requirements. Contact Do It Right Screening to discuss your specific fleet, crew, and facility requirements.

The Maritime Regulatory Framework

Maritime employers face a unique dual-regulatory environment. USCG regulations under 46 CFR Part 16 govern drug testing for vessel crewmembers, while DOT procedures under 49 CFR Part 40 set the testing protocols. Background screening requirements depend on vessel type, cargo, and port access.

Getting maritime compliance wrong can result in loss of Merchant Mariner Credentials, USCG violations, and significant liability exposure. We manage the full compliance picture so you can focus on operations.
