In the complex world of global logistics and supply chain management, the transport of hazardous materials requires more than just logistical oversight—it requires specialized expertise. The Certified Dangerous Goods Professional (CDGP) credential is the gold standard for professionals who navigate the intricate web of international regulations governing the transport of dangerous goods. This guide provides an exhaustive breakdown of everything you need to know to earn and maintain this prestigious certification.

What is the Certified Dangerous Goods Professional (CDGP)?

The Certified Dangerous Goods Professional (CDGP) is a premier professional certification designed for individuals who possess a high level of expertise in the international transport of dangerous goods. Unlike many national-level certifications, the CDGP focuses on the application of international model regulations.

  • Official Exam Name & Acronym: Certified Dangerous Goods Professional (CDGP)
  • Conducting Body/Authority: The exam is administered by the Institute of Hazardous Materials Management (IHMM). Founded in 1984, the IHMM is a non-profit organization that provides accredited credentials for professionals in the hazardous materials, dangerous goods, and environmental health and safety (EHS) sectors.
  • Purpose of Exam: It is a Professional Certification. It validates a professional's ability to interpret and apply international regulations to ensure the safe and compliant movement of hazardous materials across borders.
  • Geographic Validity: The CDGP is globally recognized. It is based on United Nations (UN) standards, making it applicable in virtually every country involved in international trade.
  • Level of Competence: This is a Specialist/Executive level certification. It is intended for experienced professionals, not entry-level staff.
  • Brief History: Established by the IHMM to address a gap in global standards, the CDGP was developed to harmonize the expertise required for various modes of transport (Air, Sea, Road) under a single, rigorous credential.

Who Can Take the Certified Dangerous Goods Professional (CDGP)? (Eligibility Requirements)

The IHMM maintains strict eligibility criteria to ensure that only qualified individuals hold the CDGP credential. The focus is heavily weighted toward professional experience.

Format Computer-Based Test (CBT)
Break Allowances No scheduled breaks (timer does not stop)

ICAO Technical Instructions Air transport, passenger vs. cargo restrictions 25%

  • IMDG Code (Sea)
  • ADR Regulations (Road)

Category Estimated Pass Rate
First-time Candidates 55% - 65%
Experienced Professionals (10+ years) 75%

Most Challenging Topics: Segregation tables in the IMDG code and navigating the "Variations" section of the ICAO Technical Instructions.
