Special-purpose exhibition areas such as the diving-education zone and equipment zone will account for approximately 40% of total exhibition space. According to organisers, all booths will be constructed using renewable, recyclable or reusable materials, reflecting the event’s sustainability commitment.

ADEX: Background and Global Credentials
ADEX was initiated by UnderWater360 and has been running for more than 30 years. It has grown into a respected international platform integrating marine-industry upstream and downstream, island tourism, technology and equipment, environmental protection, outdoor sports and diving, marine digital rights, arts education, and the renowned global “mermaid water-dance” shows.
For Hainan, hosting ADEX marks a significant milestone in the island’s evolution as a hub for global marine-tourism and dive-industry business. The event’s scale, international scope and focus on sustainability align with Hainan’s positioning as a tropical-marine destination with growing infrastructure and ambition.
For dive‐professionals, marine-equipment manufacturers, tourism businesses and island-destination promoters, the 2026 ADEX event in Hainan offers a major new platform.
