On December 18, 2025, the Hainan Free Trade Port officially initiated its island-wide customs closure, marking one of the most transformative institutional upgrades in China’s recent opening-up history. Far from creating isolation, the closure represents a higher level of openness, featuring zero tariffs, streamlined customs systems, and powerful incentives designed to attract global investors and reshape supply chain dynamics across Asia and beyond.
This article provides a comprehensive overview of what the Hainan customs closure means, the policy framework behind it, and how it is reshaping regional and global economic networks.

Understanding the Island-Wide Customs Closure
The core of Hainan’s new system can be summarized as “first-line liberalization, second-line control, and free flow within the island.”
1. First-Line Liberalization (Hainan ↔ Overseas)
Goods moving between Hainan and overseas markets enjoy significantly eased procedures. Except for prohibited or restricted items, goods may enter or exit with minimal intervention, ensuring rapid circulation and reduced compliance burdens.
2. Second-Line Control (Hainan ↔ Mainland China)
Goods entering the Chinese mainland from Hainan must follow regular import regulations and taxation. This ensures national tax security while allowing Hainan to operate as a special customs zone.
3. Free Internal Flow (Within Hainan)
Factors such as goods, capital, personnel, and data circulate freely inside the island, creating a highly efficient environment for manufacturing, trade, and innovation.
Key Policy Upgrades and Their Economic Impact
1. Expanded Zero-Tariff Coverage
Zero-tariff items have increased from 1,900 to roughly 6,600 tariff lines—covering 74% of import/export categories. Production equipment and raw materials are fully exempt from tariffs, import VAT, and consumption tax. For many enterprises, this reduces equipment import costs by about 20%.
2. Optimized Value-Added Processing Policy
A major breakthrough is the relaxation of rules around tariff-free entry of goods into mainland China:
- The former “core income ratio” restrictions are removed
- Enterprises along a supply-chain cluster can accumulate value-added together
- Goods processed in Hainan can enter the mainland tariff-free once the 30% value-added threshold is met
This makes Hainan a highly attractive site for processing raw materials, assembling components, and producing goods for the Chinese market.
3. “Dual 15%” Tax Policy
Hainan offers long-term tax advantages:
- Corporate Income Tax: 15% for qualified sectors
- Individual Income Tax: capped at 15% for eligible talent
This strengthens Hainan’s appeal as a cost-efficient hub for R&D centers, regional headquarters, advanced manufacturing, and free trade services.
4. Further Trade and Investment Liberalization
Policies now include:
- A negative list for cross-border services
- Relaxed foreign investment access
- Commitment-based business registration
- Simplified administrative procedures
- Visa-free entry for 59 countries
These reforms collectively create a world-class business environment.
Strategic Advantages for Global Supply Chains
Hainan’s customs closure does more than reduce tariffs—it reconfigures supply chain geography across Asia.
1. Strengthening China–ASEAN Connectivity
Hainan is geographically positioned as China’s closest maritime access point to Southeast Asia. Yangpu Port already demonstrates:
- Transit time reductions of up to 10 days
- Logistics cost reductions of up to 32% for ships rerouting from Singapore
This establishes Hainan as a preferred processing and logistics hub for ASEAN–China trade.
2. A Dual Solution: Cost Optimization + Market Access
For industries such as high-end manufacturing, biotechnology, clean energy, and electronics, Hainan offers:
- Lower production costs due to duty-free equipment and raw materials
- Tariff-free sales into mainland China via value-added processing
This combination is unique within China’s economic system.
3. Emerging Innovation Clusters
Hainan is prioritizing advanced sectors including:
- Space and aerospace
- Deep-sea technology
- Biopharmaceuticals
- Agricultural technology
- Green and digital industries
These sectors benefit from fast-tracked approvals, stronger IP protections, and international-standard pilot programs.
Regional Impact: New Dynamics with Hong Kong and Singapore
1. Hong Kong: Toward Complementary Strengths
While Hong Kong excels in finance, professional services, and global connectivity, Hainan provides scale, cost advantages, and mainland access.
Future supply chains may adopt a “Hong Kong services + Hainan manufacturing + global distribution” model.
Hainan directly challenges Singapore’s traditional transshipment dominance:
- Faster customs clearance
- Value-added processing advantages
- Lower logistics costs
Yet cooperation is growing—PSA maintains routes in Hainan—signaling a shift toward a multi-hub Asia-Pacific network rather than a single-center model.
Conclusion: A More Diversified and Resilient Global Supply Chain
Hainan’s island-wide customs closure represents a major institutional innovation designed to support China’s high-level opening-up. It enhances the efficiency and resilience of global supply chains and strengthens economic integration with Southeast Asia.
For global companies, Hainan offers:
- A cost-effective production base
- A new gateway to the Chinese mainland
- Streamlined access to Asia-Pacific markets
- Long-term tax and regulatory advantages
As the Hainan Free Trade Port continues to expand its openness, it is poised to become one of the most strategically important economic hubs in the region and a powerful engine supporting global trade diversification.
