Imagine moving billions of dollars worth of goods through one of the world’s busiest ports without paying a single cent in customs duties. This isn’t a hypothetical scenario—it’s the daily reality for businesses leveraging Hong Kong’s unique position as Asia’s premier re-export hub. With its strategic location, world-class infrastructure, and unparalleled free port status, Hong Kong facilitates trillions of Hong Kong dollars in trade annually, serving as the critical gateway between mainland China and global markets.

Hong Kong’s Strategic Position in Global Re-Export Trade

Hong Kong holds a unique and indispensable position in global trade networks, functioning as one of the world’s premier re-export hubs. Strategically located on China’s southern coast with sophisticated infrastructure and free port status, Hong Kong facilitates the movement of goods worth HK$4,484.5 billion annually between mainland China and international markets. The city’s role as an entrepot—a trading post where merchandise can be imported and exported without attracting duties—has been fundamental to its economic success for over 180 years.

The Gateway to China’s Markets

Mainland China accounted for 84.3% of Hong Kong’s re-export trade in 2024, representing HK$3,780.4 billion (US$484.5 billion) in value. This positions Hong Kong as an indispensable gateway for businesses seeking to access Asia’s largest consumer market. The first eight months of 2025 demonstrated robust growth, with Hong Kong’s re-exports to the mainland increasing by 16.6% year-on-year, outpacing the 15.9% growth recorded in 2024.

Understanding Re-Export vs. Transshipment: Critical Distinctions

Understanding the precise terminology is essential for businesses engaged in Hong Kong’s trade sector. The Hong Kong Census and Statistics Department recognizes four primary shipment classifications, but the most critical distinction lies between re-export and transshipment operations.

What is Re-Export?

Re-export refers to goods imported into Hong Kong from one country and subsequently exported to another country after going through Hong Kong Customs. The defining characteristic is that these goods pass through Hong Kong’s customs clearance process. Even minor activities such as relabeling, repacking, or consolidating shipments mean that goods are no longer considered simple transit cargo and become re-exports.

What is Transshipment?

Transshipment involves cargo consigned from a place outside Hong Kong to another place outside Hong Kong but removed from one vessel and either returned to the same vessel or transferred to another vessel within Hong Kong waters. The critical distinction is that transshipment goods do not go through Hong Kong Customs valuations and typically remain sealed throughout the process.

Hong Kong’s Free Port Status and Customs Framework

Hong Kong has maintained free port status since 1841, creating one of the world’s most open trading environments. Despite the transfer of sovereignty from Britain to China in 1997, the Hong Kong Special Administrative Region (HKSAR) has preserved its separate customs territory status under the “One Country, Two Systems” principle, codified in the Basic Law.

Zero Tariff Policy with Limited Exceptions

The HKSAR does not levy customs tariffs, tariff quotas, or surcharges on imports. Similarly, no value-added tax (VAT) or general services tax (GST) applies to imports or exports. This tariff-free environment makes Hong Kong exceptionally attractive for businesses engaged in international trade and distribution.

The only exceptions to this zero-tariff policy are four categories of dutiable commodities subject to excise duty:

• Liquor: Alcoholic beverages with strength exceeding 30% by volume are subject to 100% excise duty. Wine and beer duties were reduced to 0% effective February 27, 2008
• Tobacco: All manufactured tobacco products face excise duties, including specific duties per kilogram (HKD 4,005 per kilogram for tobacco excluding cigarette manufacturing)
• Hydrocarbon Oil: Including motor spirit, aircraft spirit, and light diesel oil
• Methyl Alcohol: Subject to HKD 840 per hectolitre, with additional charges for alcohol strength exceeding 30%

Customs Procedures for Re-Export Operations

Businesses engaged in re-export trade must comply with Hong Kong’s streamlined but precise documentation requirements. Understanding these procedures is essential for smooth operations and compliance.

Documentation Requirements and Timelines

The core documentation requirements for re-export operations include:

1. Import Declaration: Must be lodged with the Census and Statistics Department within 14 calendar days after receipt of goods. Not required for sample shipments valued below HKD 1,000 or personal gift shipments.
2. Export/Re-Export Declaration (Form 2): The standard export/re-export declaration form used for non-Hong Kong manufactured clothing and footwear items, as well as articles exempted from declaration charges. Must be lodged within 14 calendar days of exportation.
3. Related Forms: Form 2A for export declaration of Hong Kong manufactured clothing and footwear items, and Form 2B for export/re-export declaration of articles exempted from declaration charges.

Declaration Charges and Penalties

Declaration charges range from HKD 0.2 to HKD 200 per declaration (plus Clothing Industry Training Levy for exports of Hong Kong manufactured clothing items). Penalties apply for:

• Failure to lodge required declarations within the specified period
• Knowingly or recklessly lodging inaccurate declarations
• Misuse of form types (requiring re-lodgement with correct form and payment of late lodgement penalties)

Licensing Requirements for Specific Commodities

Certain commodities require import or export licenses:

• Dutiable Commodities: Importers must obtain import permits and pay excise duty before shipment release
• Textiles: Registration with the Textile Traders Registration Scheme
• Reserved Commodities: Rice, frozen meat, and frozen poultry require import licenses from the Reserved Commodities Unit of the Trade Department
• Strategic Commodities: Under the Import and Export Ordinance (Chapter 60), licenses are required for import/export/re-export/transshipment of strategic commodities

Rules of Origin and Certificate Requirements

Proper origin certification is crucial for re-export operations, particularly when goods qualify for preferential treatment under free trade agreements.

Hong Kong Rules of Origin

Hong Kong follows the internationally accepted principle of substantial transformation when determining origin. Goods are accepted as Hong Kong-origin if they meet one of two criteria:

• They are natural products of Hong Kong, or
• They have undergone manufacturing processes in Hong Kong that permanently and substantially changed the shape, nature, form, or utility of materials used in manufacture

Certificate of Origin – Re-export (CR)

This certificate applies to shipments exported from mainland China (or other countries) to Hong Kong and subsequently re-exported to overseas destinations. The CR certifies that re-exports are of their declared origin and exported under the Hong Kong company’s name.

To obtain a Re-export Certificate of Origin:

• Eligibility: Any Hong Kong company with a valid Business Registration (BR) Certificate
• Primary Requirement: Certificate of origin issued by an authorized certification body in the originating country/place
• Alternative Documentation: In exceptional circumstances (where no certification service exists), supplier invoice from originating country plus transport documents (import manifest, Bill of Lading, or Air Waybill)

Practical Examples of Re-Export Scenarios

Understanding how re-export works in practice helps businesses plan their operations effectively. Here are three common scenarios:

Example 1: Electronics Distribution

Scenario: A Hong Kong trading company imports smartphones from South Korea and re-exports them to mainland China.

1. Import smartphones from South Korea to Hong Kong
2. File import declaration within 14 days (no import duty charged)
3. Store goods in Hong Kong warehouse
4. Repackage products with Chinese-language labels and documentation
5. Export to mainland China under CEPA preferential arrangements
6. File export/re-export declaration (Form 2) within 14 days
7. Obtain Certificate of Origin – Re-export (CR) certifying Korean origin

Benefits: No Hong Kong duties, efficient logistics, access to mainland market, simplified customs procedures.

Example 2: Wine and Spirits Distribution

Scenario: A distributor imports French wine (12% alcohol) and Scottish whisky (40% alcohol) for re-export to Asian markets.

1. Import wine and whisky to Hong Kong
2. Wine (12% alcohol): No excise duty (below 30% threshold)
3. Whisky (40% alcohol): 100% excise duty applies
4. Pay duty on whisky before release from bonded warehouse
5. File import declarations for both products
6. Re-export portions to Singapore, Vietnam, and mainland China
7. File export/re-export declarations
8. Obtain French Certificate of Origin for wine and Scottish origin for whisky

Benefits: Wine enjoys duty-free treatment; whisky duty paid only on portions entering Hong Kong market, not on re-exported quantities.

The CEPA Framework: Enhancing Hong Kong’s Gateway Function

The Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA), signed on June 29, 2003, further enhances Hong Kong’s gateway function. CEPA provides:

• Tariff-free export to mainland China for Hong Kong-origin goods
• Preferential access for specific service sectors
• Reduced or eliminated entry thresholds for Hong Kong service providers (enhanced in October 2024 revision)
• Institutional cooperation framework under “One Country, Two Systems”

CEPA demonstrates that mainland China regards Hong Kong as a separate customs territory with full and independent autonomy in conducting external commercial relations. This framework has been instrumental in maintaining Hong Kong’s position as mainland China’s third-largest merchandise trading partner, representing 5.0% of the mainland’s total trade in 2024.
