Exporters should ensure that the correct and latest dangerous goods classification, such as UN3556 for lithium-ion battery-powered vehicles, is accurately declared on commercial invoices.
As Hong Kong auto parts exporters navigate customs compliance requirements, DHL can provide expert customs clearance support to help reduce the risk of shipment delays.

The auto parts and accessories industry plays a significant role in Hong Kong's economy, contributing to both domestic and international trade. As a major logistics hub in Asia, Hong Kong International Airport is home to the world's busiest cargo airport, with over seven million tonnes of annual handling capacity. This robust infrastructure enables exporters to rely on highly efficient logistics solutions to seamlessly distribute car parts worldwide. This blog aims to provide an in-depth industry study focusing on the logistics of exporting auto parts and car components from Hong Kong, shedding light on new opportunities brought by the rise of the EV market.

Overview of the auto parts and accessories industry in Hong Kong

According to the Observatory of Economic Complexity (OEC), Hong Kong’s auto parts industry recorded total exports of USD 735 million in 2024, which made Hong Kong the 37th largest exporter in this category globally. Its core competitiveness is driven by entrepot trade, supply chain management, and regional distribution rather than local manufacturing.

  • Hub-and-Spoke Regional Distribution: Instead of domestic vehicle manufacturing, local enterprises focus on high-value activities such as procurement and cross-border distribution.
  • Cross-Border Transport with Mainland China: Exporters leverage close geographical ties and tariff preferences under the Closer Economic Partnership Arrangement (CEPA) to utilize bonded transport arrangements, effectively supporting the operational needs of Just-in-Time (JIT) delivery models.
  • Aftermarket Demand: Beyond new vehicle production, maintenance, replacement, and upgrade parts remain a key source of demand. Efficient logistics and customs clearance are essential to prevent delays and support supply chain continuity.

EV Battery & Parts: New Trends and Compliance

EV industry growth is expanding automotive parts export demand beyond traditional mechanical components to higher-value electronic and battery-related products. EV supply chains rely more heavily on batteries, electronic control systems, and charging equipment. These products often involve dangerous goods regulations, documentation requirements, and temperature-control considerations, making logistics and compliance capabilities increasingly important for cross-border trade.

  • Growing Market Demand: The International Energy Agency (IEA) reports global EV sales have surpassed 20 million, accounting for roughly one-quarter of global new car sales. China remains the largest market with a near 55% share, while manufacturers such as BYD continue to drive growth across the EV supply chain.
  • Lithium Battery Export Dangerous Goods Regulations: According to the 67th edition of the IATA Dangerous Goods Regulations, a lithium-ion battery shipped by air must have a SoC not exceeding 30% and must be accompanied by a UN38.3 test summary and a Material Safety Data Sheet (MSDS). Exporters must also declare the correct UN dangerous goods number, such as UN 3556 for lithium-ion battery-powered vehicles and UN 3558 for sodium-ion battery-powered vehicles.

Given the increasing complexity of shipping requirements, exporters should work with logistics partners with dangerous goods handling expertise.

Major Automotive Parts Exported from Hong Kong

Hong Kong exports a wide variety of auto parts and accessories across different  HS codes, requiring exporters to clearly understand product applications, dimensions, weights, and shipping requirements to determine the most appropriate packaging and transport solutions.

  • Engine, Transmission, Suspension, and Body Parts: This category covers engines, gearboxes, suspension system components, and exterior body accessories. Since some items are bulky or irregularly shaped, exporters must verify the packed dimensions and weight to select suitable packaging methods.
  • Electrical and Electronic Parts: This includes alternators, starter motors, wiring harnesses, car audio systems, navigation devices, and sensors. Shipping documents should explicitly state the product name and application; if the shipment contains any type of battery, the applicable carrier requirements must be confirmed beforehand.
  • Aftermarket Accessories: Encompassing high-performance components, vehicle modifications, and used car parts. Exporters must provide accurate descriptions on commercial invoices and prepare documentation based on the actual condition of the goods and the specific destination regulations.
  • EV Accessories: These involve dedicated energy storage, charging, or drive systems—such as battery modules, charging devices, electric motors, and battery management systems—which differ significantly from standard electronic components. Particularly for the EV battery, exporters must verify carrier policies and required documentation before booking transport.

Key Transportation Methods for Car Parts

The most suitable transport mode depends on shipment urgency, cargo size, and destination requirements.

  • Air Express: Ideal for high-value, compact, or emergency repair components like electronic circuit boards and control units. Depending on the destination, customs clearance, and service arrangements, shipments may be delivered as early as the same day.
  • Road Freight: Suitable for regular scheduled shipments between Hong Kong and Mainland China, easily accommodating inventory replenishment and factory production schedules.
  • Ocean Freight: The most cost-effective option for bulk orders or heavy automotive parts such as tyres, body panels, and suspension systems, albeit with longer transit times.

When component shortages threaten production, exporters should prioritize faster shipping methods to minimise equipment downtime. For scheduled restocking, comparing the time and costs of different methods is recommended. Exporters must also verify the packed dimensions, weight, and specific destination requirements before selection.

New Requirements for EV Battery Logistics

EV batteries often require tighter delivery timelines and stricter environmental controls than conventional automotive parts. EV battery modules contain a high concentration of precision electronic components that are more sensitive to changes in temperature and humidity. 

As a result, many EV parts exporters prefer temperature-controlled air freight or express delivery services. DHL Express facilities provide controlled storage environments that help protect battery performance throughout transit.
