The Zhuhai port of the Hong Kong-Zhuhai-Macao Bridge recorded import and export value of 96.17 billion yuan ($14.1 billion) in the first quarter, up 55.4 percent year-on-year, driven by the opening of a comprehensive designated supervision site at the port last year, according to statistics from Gongbei Customs.

The site, which expanded the range of goods that can clear customs at the bridge port, has been particularly consequential for trade with ASEAN countries. Import and export value to the bloc reached 26.8 billion yuan in the first quarter, a year-on-year jump of 203.1 percent, with exports of optical modules, plastic products and clothing among the main drivers.

"Optical module products are one of our core products, and currently we have shipments heading to ASEAN countries through the bridge almost every day," said Jiang Bo, head of the supply chain department at Guangdong Hisense Broadband Technology. "The convenient cross-border transportation via the bridge ensures reliable logistics efficiency, allowing us to handle special and urgent orders."

The supervision site has also opened new import channels for fresh perishables. Since becoming operational, it has accepted fresh products from Canada, New Zealand, and several Southeast Asian nations. Over the past year, 339.3 tons of chilled aquatic products, edible aquatic animals, and fruit have been imported via the bridge port, valued at more than 20 million yuan, Customs data showed.
