　　BEIJING, April 17 (Xinhua) -- A truck loaded with 1.3 tonnes of clothing, hats, sunglasses and other goods departed from the cross-border e-commerce warehouse at the comprehensive bonded zone of Beijing Daxing International Airport (BDIA), heading to the international cargo terminal of China Southern Air Logistics Co., Ltd. at the airport.

　　At 4 p.m., these made-in-China daily necessities were shipped to Tashkent in Uzbekistan via flight CZ6027.

　　“Almost every flight on this route carries goods in and out of the bonded zone,“ said Song Bing, a manager at the logistics company.

　　Comprehensive bonded zones are customs-supervised areas with streamlined clearance procedures, serving as vital platforms for China's opening-up endeavors. Policies such as tax refunds upon entry, bonded imports and the free flow of goods within the zone help enterprises significantly reduce institutional transaction costs.

　　Over 160 such zones nationwide play a crucial role in expanding trade, attracting foreign investment and driving industrial upgrades.

　　At the BDIA bonded zone, trucks carrying goods arrive continuously. Inside bonded warehouses and production workshops, modern machinery operates at full capacity, fueling a bustling environment featuring manufacturing and research and development (R&D).

　　Having settled in the zone in 2022, Beijing CRS Medical Device Co., Ltd. now produces 700,000 dental implants annually, serving clients nationwide.
